Floating Instream Tidal and Solar (FITS) Power Plant - Nepal Pilot Project
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Harvesting hydrokinetic energy from running river water presents a highly attractive addition to the existing renewable energy sectors. Critically, and unlike most other renewables, this technology guarantees a predictable and consistent energy output which can contribute to the baseload power requirements of its energy off-takers. AEL has developed an innovative hybrid technology which couples run-of-river hydrokinetic generation with solar - the Floating Instream Tidal and Solar (FITS) power plant. FITS technology has been specifically optimized for river deployments, and is scalable to enable both energy access and utility scale power generation. This project will deliver the first fully developed FITS pilot, supplying constant renewable power to an off-grid community in rural Nepal. The electricity supplied will be used to provide lighting and cooking facilities to households in the community, and will additionally power water filtration and pumping equipment, providing access to clean water for drinking and water for agricultural industry.
Harvest Cool
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Agriculture plays a significant role in the Nigerian economy, contributing 22.35% GDP (2021) and employing \>70% of its population at subsistence level(1). Onions are a lucrative, dry season irrigated crop and ~2 Mt/annum are produced, largely in Northern Nigeria. Opportunities for onion farmers are not fully realised, due to low investment in agronomic practices, and post-harvest losses (up to 50%). Traditional drying of onions could be replaced by a cool supply chain from field to market, however, access to energy for chilling hampers this initiative. The Harvest Cool project represents stakeholders from farming business, agricultural services, and technology providers who will deliver an integrated energy system to develop a low carbon cold storage system for onions grown in Nigeria. The partnership comprises PyroGenesys (biomass pyrolysis technology); Lavender Fields (agricultural produce aggregator and marketer); the Nigeria Agribusiness Group and Agrolog (agricultural extension services, Nigeria) and University College London (Life Cycle Assessment input). The project builds on a feasibility study carried out by Lavender Fields, identifying farming communities which sell to a major onion market (Karfi) in Kano, Nigeria, with a demonstrable need to develop cool supply chains for perishable crops. The project is innovative in bringing together unique engineering designs which address cold storage for transport from the field to a central storage point. The project is also innovative in the conception of a business model which considers energy provision; the benefits of food waste reduction; adding value to low income farming communities; and a circular carbon farming system with potential to improve agronomic conditions and carbon sequestration in soils. The project will be assessed quantitatively through Life Cycle Assessment of global warming potential (GWP) of the overall system and qualitatively through a programme of community interactions, demonstrating the project's contribution to addressing SDG7 Affordable and Clean Energy and SDG13 Climate Change.

Rice-straw powered biowaste to energy
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
This consortium, let by Carnot Ltd, seeks to develop the world's first profitable rice-straw bioenergy demonstrator for a rural community in Lombok Island, Indonesia. Rice straw is separated from the grains during harvesting and either combusted (producing CO2) or left to decompose (producing methane with 25\* Global Warming Potential) due to challenges with harvesting it, particularly in flooded paddy fields (a common occurrence). Straw Innovations has created innovative technology that overcomes the barriers to harvesting it in all weathers, unlocking a potential 300Mt of rice straw generated in Asia every year. Rice straw has high ash content (around 20%), comprising about 75% silica. This, combined with other components in the straw (chlorine, potassium) causes melting and slagging / fouling in boilers when combusted. Hence, it is not an easy fuel to chop or combust. PyroGenesys have developed a lower-temperature pyrolysis process which can convert rice straw into Biochar, a carbon-sequestering fertiliser that can be used by the rice farmers, and biofuel. The carbon sequestered can be traded on carbon removal markets. Surplus biofuel not used to generate electricity can be sold. Electricity is a low-value commodity and renewable electricity projects will typically require very large scale to be profitable and attract funding required from investors. PyroGenesys' process solves this problem by opening up two very high-value revenue streams. Carnot is developing ceramic engine gensets with double the efficiency of state-of-the-art diesel gensets, capable of operating on all fuels. These will provide electricity to the rice mills as their base load as well as electricity to a rural community. Integrating Carnot's gensets enables revenues generated by biofuel sales to be maximised. Indonesia: * Is the world's 5th largest GHG emitter. * Is the largest producer of biofuels worldwide. * Has mandated to convert a significant portion of its palm oil into FAME biodiesel. There is a reluctance to move to renewable energy due to fossil fuel sunk costs/subsidies and no proven profitable off-grid low-carbon energy business model. This demonstrator project aims to be the catalyst to breaking the deadlock and unleashing investment into Indonesia's enormous renewable energy potential. Key project outputs: * Pilot-scale demonstration of business model feasibility * 200,000kg rice-straw feedstock; * 76,000kg value-added-biochar/53,200kg carbon sequestration/80,000kg biofuel; * 2.28MWh electricity provided to rice mill.
Technical and Societal Innovation for Delivering Access to Community Wide Affordable Cylindered CBG for Cooking and Sustainable Fertiliser
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Natural Synergies Ltd (NS) Industrial Research project "Technical/Societal Innovation for Delivering Community Wide Affordable Cylindered CBG for Cooking and Sustainable Fertiliser" is to establish new data and knowledge, which would eventually lead to establishing an demonstration waste to energy process based around an advanced anaerobic digestion treatment process that has been developed by NS. This seminal development work will utilise a sectoral system of innovation which will eventually lead to nationwide joint partnerships, between NS the (technology provider) and poorer sectors of the local community. NS together with project partners, are involved in a project that concerns advanced pre-treatment and processing of faecal sludge and organic waste, providing enhanced, efficient energy security/generation, utilising locally available resource and GHG emission savings. NS aims in this Industrial Research project, to develop a stand-alone enhanced energy pre-processing technology, for rural and peri-urban locations in developing countries, increasing the efficiency of energy generation for the supply of affordable clean energy, for cooking and transport to the poor and marginalised local community and also with the production and supply of a sustainable source of fertiliser to local farmers. The decentralised and localised waste to energy plant, will also serve as a low cost faecal sludge management system and organic waste treatment facility, preventing the dumping of waste into waterways and land, providing benefits to both the environment and health to the local community. During the course of the project, the team will work in close co-operation with existing co-operatives and where necessary, expand and create further entrepreneurial partnerships, encouraging women's empowerment, social inclusion and security in the overall waste supply chain and product sales and marketing. This will lead to establishing a circular economy for waste treatment with close co-operation between the energy plant operator and the local community. Although specialised components will be sourced in the UK, NS will establish non-specialised component manufacture/build using local industries leading to job creation in DC, economies in plant build, short inbound/outbound feedstock and product supply logistics, marketing, sales and service supply chain.

Generation Malawi: A study of family, maternal and childhood mental health
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
A lack of research training, resources, infrastructure and data in Low- and Middle-Income Countries (LMIC) greatly limits their ability to conduct studies of common mental health conditions. Nowhere is this more true than in Africa generally and in Malawi specifically, where sparse mental health care alone limits not only clinical research capacity, but also the ability to attract inward investment. In a partnership between UK and Malawian institutions, we propose to directly address this challenge by building clinical research capacity through the coordinated appointment of new researchers and research assistants, a programme of education and dissemination, and the development of a population mental health dataset focussed on an area of great unmet need - the mental heath of mothers and their children. After a period of piloting our research assessments and obtaining the necessary approvals, we will recruit 5000 mothers prior to delivery of their child from antenatal clinics in Lilongwe and Karonga districts, selected to represent urban and rural populations respectively. We will assess the mental health of mothers before and after birth, and the mental health of their spouses and other family members with a view to identifying the major risk factors for mental health disorders and mitigating variables that promote resilience. We will then examine the impact of maternal and, where possible, paternal mental health on the neurodevelopment of their offspring. In addition to creating new and highly valuable data, we will also create the bioresources needed for future genetics and 'omics based research. We believe this is essential to prevent the current imbalance in genetic research favouring rich countries of predominantly European ancestries leading to greater entrenchment of global health inequalities. As part of the proposed work, we will develop internationally competitive research capacity and datasets in Malawi, augment standard of care treatment, develop research training and the availability of affordable and effective interventions for depression and other common mental disorders, such as the "Friendship Bench" intervention. Our research will be multidisciplinary, involving experts from psychiatry, clinical psychology, nursing, reproductive and child health, and social sciences in both UK and Malawi. Throughout the project, we will carefully monitor our progress and impact on the participants and their communities. The project, if funded, will lead to a step change in mental health research capacity in Malawi, paving the way for new inward investment and the development of evidence based interventions and policies.
Caregiver influences on child psychological adjustment following trauma; a longitudinal study of a high adversity South African population
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
"Children who experience very frightening or traumatic events (such as car accidents, assaults, serious injuries) are vulnerable to developing posttraumatic stress disorder (PTSD) and other psychological difficulties following their experiences. Such problems can be extremely distressing, and affect a significant proportion of trauma exposed children. One factor that has the potential to influence such outcomes is the informal support that children receive from their parents/caregivers posttrauma. In research we have conducted in the UK, we found that certain aspects of caregiver responses can have an impact upon children's psychological recovery following trauma. In particular, where caregivers encourage ways of coping in children that allow them to avoid being reminded of the trauma, and/or talk to children about what happened in a way that emphasizes high levels of threat associated with the trauma, children are more likely to experience persistent symptoms of PTSD. These caregiver responses may influence child symptoms as a consequence of children themselves then making more negative appraisals in relation to what happened, and by influencing child coping behaviours. We propose to extend our UK work to the study of a high adversity international population. To date, only a small proportion of PTSD research has been conducted in low-and-middle-income countries (LMICs). This omission is important, as LMIC children may be particularly vulnerable to trauma exposure for a variety of reasons (e.g., poverty, crime, regional conflict). It is essential to establish whether psychological and social processes that have been linked to child PTSD in lower risk settings still apply in contexts where levels of ongoing threat and the likelihood of exposure to recurrent traumas are high. In particular, although we know that caregiver support is a key predictor of child psychological recovery following trauma in high income countries, our understanding of the elements of support that can help children from high adversity, lower income contexts is almost non-existent. This is important, as such children are almost certain to rely on such informal support following trauma exposure, due to limited access to formal psychological services. To address this critical gap in our knowledge, we plan to study the psychosocial factors that contribute to PTSD in a group of children (aged 8-16 years) from a deprived community in South Africa, in which rates of serious trauma exposure are extremely high. We will recruit 250 children who have experienced trauma within 2 weeks following the event. We measure how caregivers provide support, as well as children's initial levels of symptoms. We will then follow-up children and caregivers 3 months and 6 months later, measuring their PTSD symptoms. We will examine whether there are particular elements of caregiver support in the aftermath of trauma that are associated with higher or lower levels of symptoms in children further down the line. We we also will test whether caregiver influences operate via changing key psychological processes (trauma appraisals, coping) in the child, and will take account of caregivers' own trauma-related distress in our study. In addition to helping us to understand what kind of social support is best for children who experience trauma, our project will provide much needed information about the development of PTSD in children from high adversity, low income communities. This is important: at the moment we are lacking even basic information about risk of PTSD in the acute aftermath of trauma among such children, including the proportion who will initially develop this disorder following trauma, the window of time during which children may recover naturally following the event, and the proportion likely to experience persistent disorder and need intervention. This is a major barrier to developing screening and intervention programmes, which our study will be able to address. " COVID-19
ESRC-FAPESP Creating competitive advantage by serving marginalised communities: UK multinationals and inclusive development in Latin America
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
"Multinational Enterprises (MNEs) are often blamed for only serving the elite population when they operate in emerging markets. In addition, they require local governments to create infrastructure and arrangements that can support their activities in the respective country, thus diverting resources from underserved communities within the country towards serving the elite population. The purpose of this study is to explore how multinationals from advanced markets can contribute to the achievement of the United Nations' Sustainable Development Goals by addressing the needs of underserved populations and marginalised communities in emerging markets, while also providing expectations of long term economic return to their shareholders. Considering the increased awareness of doing good while doing well, MNEs are beginning to realise that profit maximization is not the only route to success. They need to improve their image and demonstrate that their existence is beneficial for the society in general, that is a more long-term route to achieve a competitive advantage. We intend to uncover the mechanisms and actions required by these companies to serve marginalised communities and to create a positive image in the society. To do so, we build from stakeholder theory, social entrepreneurship and value creation literature, and offer a qualitative cross-country study in Latin America. We will focus specifically on the experience of UK multinationals in Brazil and Colombia. We will collect data through focus groups and in-depth interviews with multiple actors (such as multinationals' executives, NGOs, underserved consumers, community leaders, local government representatives, investment promotion organizations, and local entrepreneurs). We will triangulate by comparing data from focus groups, interviews, and secondary sources to draw trustworthy conclusions. Further, we will use pattern matching and case comparison to analyse and make sense of data and draw conclusions. The MNEDEVELOP project is context specific and will culminate in a set of good practices for decisionmakers to incentivize positive actions by foreign firms that result in economic and social benefits for poorer communities in Brazil and Colombia. To address this complex research question, resources and expertise from the UK and Brazil will be combined. Principal and co-investigators have a successful track record in conducting research on MNEs impact in developing countries, on local firms, on engaging in training for managers, and working directly with policy makers. Key investigators are well-known international business scholars and experts with numerous relevant high-level publications. The UK team will contribute with theoretical framing, sharing research and training skills with local researchers, taking the lead in the analysis of data, producing actionable documents for stakeholders, and drafting academic publications. The Brazilian team will provide indepth knowledge of the research context, drawing on wider networks with businesses locally and close engagement with local societies while collecting data. As results we will provide guidelines for multinationals and other stakeholders as to how inclusive development can be achieved. " COVID-19
Highlight SDAI: Successful Reintegration Trajectories of Ex-Combatants in Colombia
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
In collaboration with researchers at ARN and academics at Jorge Tadeo Lozano University, the proposed research has identified the need to better understand what constitutes a successful reincorporation trajectory contrasting inclusion and marginalisation of former combatants. The project will identify the individual socioeconomic determinants of successful reintegration as well as the spatial and institutional context in which former FARC combatants find themselves. Moreover, the reincorporation process includes the provision of seed funding for business projects, so-called "productive projects". The research also aims to better understand why some productive projects have been successful while others failed. Here too, we will consider individual and contextual factors. Apart from data held by the ARN, relevant regional and municipal level data are held by the Colombian National Planning Department, the Ministry of Defence, National Service of Employment, Ministry of Education, the Institute for Family Protection, and the Office of People Advocacy (Ombudsman Office). The research project aims to support information exchange between ARN and these relevant Colombian institutions, as well as strengthen the capacity within the ARN to analyse such nested data using spatial and network analysis techniques.
(2REST) Responsibilities for Resilience Embedded in Street Temporalities: mapping street youth lived resiliences through analysis of secondary data
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
2REST aims to explore the experinces of homeless street youth and their resilient reponses to diffculties as they grow up in contexts of stress and vulnerability in African cities. Through secondary data analysis of the Growing up on the Streets qualitative data, the objective is to go beyond individual person-centred responses to stress and understand the multiple systems involved in overcoming difficulties over space and time as young people grow up. The resulting evidence will provide a better understanding of street youth resilience and all the factors involved. The 2REST project further aims to translate these findings and apply the learning to outcomes for policy and practice in order to improve street youth lives.

Highlight: Identifying barriers to mental healthcare for civilians affected by protracted armed conflict in Colombia
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
"This will be the first project to identify invisible victims using innovative data-linkage between i) a nationally representative psychiatric epidemiological study (N=12k+) that used active case ascertainment in the general population, and; ii) data fromthe national mental health programme (N=1 million+), and the first to examine quality of care at the population level. We will use robust statistical analysis to identify: 1) social, health, and demographic drivers of being an invisible victim of conflict - who has conflict-related mental health needs but who never accesses services 2) social, health, and demographic drivers of treatment delay, quality of care, and outcome in people with conflict-related mental health needs who successfully access services 3) the extent to which gender-based and sexual violence mediates conflict-related mental health needs and poor treatment access / outcome in women and girls All 3 aims address urgent national policy issues. Aim 3 was suggested, and most prioritised by, our panel of people with lived experience of the armed conflict who will continue to co-produce this project."
DARA Development in Africa with Radio Astronomy Phase 3
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
This proposal is to continue, deepen and expand the Development in Africa with Radio Astronomy (DARA) project. DARA is a human capital development programme with the principal aim to develop high tech skills in radio astronomy in the eight developing African countries that partner with South Africa in the hosting of the mid-frequency telescope of the Square Kilometre Array (SKA). The first two phases utilized the Newton Fund and delivered a basic training to over 300 young people as well as Masters and PhD level training. This proposal is once again a bilateral UK-SA project bidding for Official Development Assistance (ODA) funding as part of the Tomorrow's Talent strand of the new International Science Partnership Fund (ISPF). In this new phase we will extend the HCD pipeline to establish postdoctoral fellows in African partner institutions for the first time. The aim is to complete the establishment of radio astronomy research groups in each partner country so that their citizens can fully engage with the SKA project. We will also continue the basic and Masters level training programme. This third phase will also encompass elements of the DARA Big Data sister project to deepen the training in machine learning techniques required to analyse SKA data and embed synergies with Earth Observation data. We will also continue and expand our partnership with the space sector to showcase how the skills of radio astronomy can be utilized to address development challenges in Africa. The industrial partners also bring entrepreneurship and business start-up experience. Overall, the DARA project addresses the UN Sustainable Development Goals (SDGs) in terms of increasing high tech skills, research activity and international cooperation.

Efficient Photoelectrochemical Green Energy System based on Hematite Photoanodes Heterostructured with Selected 2D Transitional Metal Dichalcogenides
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
This project addresses the urgent need for sustainable energy solutions by enhancing photoelectrochemical (PEC) water-splitting technologies, which convert solar energy into storable hydrogen fuel. With the increasing global focus on mitigating climate change, the development of efficient, renewable energy technologies is paramount. PEC water splitting, a process that uses sunlight to produce hydrogen, presents a promising pathway to this goal. Our initiative centres on improving the efficiency of hematite-based PEC devices through innovative heterostructures incorporating two-dimensional (2D) transition metal dichalcogenides (TMDCs), such as SnS₂, MoS₂, SnSe₂, and MoSe₂. Hematite has long been studied for its potential in solar-driven water splitting due to its strong visible light absorption and favourable theoretical solar-to-hydrogen (STH) conversion efficiency. However, its practical application has been limited by issues such as poor electrical conductivity, slow charge transport, and high recombination rates of electron-hole pairs. By integrating hematite with 2D TMDCs, we aim to overcome these challenges, enhancing the material’s performance through improved charge transfer, reduced recombination losses, and optimised band alignment. This approach promises to boost STH conversion efficiency and achieve the 10% benchmark set for practical applications, making a significant contribution to the development of scalable, clean energy solutions. The project not only advances scientific knowledge but also brings substantial benefits to researchers and institutions in Africa. The collaboration between UK and African institutions facilitates access to cutting-edge facilities and expertise in the UK, which are critical for the successful implementation of this research. African researchers will have the opportunity to train on advanced characterisation tools and gain hands-on experience with state-of-the-art PEC technologies. This exposure is invaluable for building their technical skills and enhancing their research capabilities. Moreover, the project fosters networking and collaborative opportunities between African and UK researchers, promoting the exchange of knowledge and ideas. This international collaboration helps to strengthen research networks, opening doors for future partnerships and joint ventures. African institutions will benefit from the establishment of sustainable partnerships and the development of local expertise in advanced energy technologies. Additionally, the project includes outreach and dissemination activities, which will raise awareness and engage various stakeholders, including the public and industry players. These activities will not only highlight the advancements in PEC technology but also showcase the contributions of African researchers to global scientific progress. In summary, this project is poised to make significant strides in improving PEC water-splitting efficiency, with the added advantage of enhancing research capacity and collaboration between African and UK institutions. By addressing key challenges in renewable energy technology and providing valuable training and networking opportunities, the project aims to contribute to the global transition to clean energy while strengthening the scientific community in Africa.
SAPPHIRE : Supra-African Physics Partnership for Health Innovation and Radiotherapy Expansion
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Vision: SAPPHIRE is a UK-African research and training partnership which will build capacity in Africa to obtain better fault information of M-LINACs and to feed into an M-LINAC tailored to low- and middle-income countries (LMICs). Importance: Our previous STFC funded ITAR project surveyed 28 African countries, revealing two major challenges: 1) many African M-LINACs suffer from considerable down-time down due to frequent breakdowns of specific components; and 2) a shortfall exists in radiotherapy workforce, especially trained physicists. Team: We will bring together M-LINAC facilities in Accra and Kumasi (Ghana) and Pretoria (South Africa), two STFC accelerator centres in Oxford & Lancaster, and medical physics expertise from Cambridge in partnership with CERN and ICEC. Our global team has decades of experience in accelerator and M-LINAC research and has engaged in collaboration with African partners since 2010. Areas of Focus: Specific focus will be given to post-acceleration beam-shaping systems that match radiation beam to tumour target (i.e. multi-leaf collimator devices). MLCs are prone to frequent breakdowns. Project SAPPHIRE has 3 key objectives: Objective 1: To identify junior physicists in Africa to train in electronic data collection and analysis of usage and fault data from M-LINAC stock in their own centres. Objective 2: To use gathered data to assess the effect of faults and to define MLC tolerances, studying different candidate leaf designs for an improved and robust MLC unit. Objective 3: To compare the performance of candidate designs with current-generation commercial M-LINAC devices for treatment planning using real-world clinical data. We will achieve these objectives through four key Physics Education And Research Linkage work packages (PEARLs): PEARL-1 Data Capture. We will create a solution for electronic data capture (EDC) of M-LINAC fault and usage data, enhanced with key environmental factors (e.g. operating temperature, voltage stability, humidity and atmospheric particulate levels). Hasford, Addison and Nethwadzi will supervise training of junior physicists for EDC work in Ghana and South Africa. PEARL-2 MLC Improvements. Dosanjh, Burt, Addison, Hasford and Nethwadzi will develop an understanding of the causes of MLC faults, analyse the implications on the radiation patterns using Geant4 and develop improvements of the MLC design. This will allow researchers throughout our collaboration to investigate the relationship between reported fault and environmental data and the design constraints of the MLC. PEARL-3 Training workshops. Burt, Dosanjh, Jena, Ayette, Addison, Grover, Hasford, and Nethwadzi will establish two physics schools in Africa, first one in Ghana focussing on LINACs, their sub-components and faults/maintenance of those system and the second in Pretoria focussing on radiation physics simulations and imaging and treatment planning. PEARL-4 Treatment planning. Jena, Dosanjh, Ayette and Grover, will compare the performance of candidate hardware designs with current-generation commercial M-LINAC devices in a suite of treatment planning tasks typical of today’s clinical demands. Pathway to success: 1) We have a rich and capable multi-professional team and a long track record of successful collaboration. 2) We will make lasting impact through successful upskilling of junior physics staff in Africa, to perform better research and development in M-LINAC component design and operational robustness. 3) Data from SAPPHIRE will be used by our global consortium (ICEC) to design and deploy a novel fault tolerant M-LINAC design for LMICs by 2030.
Temperature-sensitive Earth-abundant Catalysts for green Hydrogen production
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Hydrogen production via water electrolysis technology has been a major focus of discussions for practical carbon-neutral transportation fuel and a key component for other chemical syntheses for the past decade. Particularly, Africa’s total announced electrolyser pipeline capacity has reached 114 gigawatts. However, the costs of water electrolysis to be reported in the range of 2-5 £/kg H2, which is still twice as expensive as the existing fossil fuel-based technologies. Among various electrolyser technologies for hydrogen production, alkaline water electrolysis is considered to be the most mature type for industrial scale-up and has strong cost-effectiveness. Despite these advantages, its cold-start nature, unfortunately, requires a certain ramping-up time (approximately 1 hour). This makes it challenging to integrate with renewable energy sources, which are difficult to predict. Alkaline water electrolysis at elevated starting temperatures offers a promising solution to enhance catalytic reactivity and reduce required electric energy, increasing cost-effectiveness. The cobalt- and nickel-based catalysts, known for their prominent temperature dependence, could be the key to enhancing the hydrogen production rate. In this study, we aim to establish a feasible fabrication method of temperature-sensitive catalysts for alkaline water electrolysis and to explore the multi-element catalysts' physical and chemical bonding structure change at elevated temperature conditions. Exploring the underlying mechanism of intrinsic kinetics change is a challenging yet crucial step towards more efficient and cost-effective hydrogen production. The ultimate goal of the proposed collaboration entitled "Temperature-sensitive Earth-abundant Catalysts for green HYDROgen production (TECHydro)" is not to develop new catalysts but to discover new combinations that have a high-temperature sensitivity and explore underlying principles, giving rise to fresh perspectives of the developed catalyst for their application to AWE. The outcomes will provide a methodological achievement in cost-effective catalyst preparation. Moreover, the project will make a rigid bridge for further joint-research funding applications and staff exchange between African (South Africa and Kenya) and UK partners. We believe that the outcomes of this study could set benchmarks for hydrogen production that operates more efficiently in South Africa and Kenya's hot climate, contributing to the global transition towards a hydrogen economy.
Compound-Semiconductor-Enabled Renewable Energy System for Powering Critical Buildings in Africa
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Africa’s power supply systems for critical loads, such as healthcare facilities, are transitioning to a more sustainable, efficient and reliable future. This is driven by the integration of renewable energy, which includes AC and DC power conversion enabled by power semiconductors switching at increasingly high frequencies (e.g., 10–100 kHz). The semiconductors’ operation causes power loss, reducing energy efficiency, and they are the most vulnerable components, counting for 20%–30% of the failure of power conversion systems. Improving the performance of the semiconductors will thus provide significant benefits in energy saving and system reliability improvement. For example, a 1% increase in efficiency in solar photovoltaic (PV) inverters and a 1% in reliability will make 150 GWh more energy available to critical healthcare facilities in Africa. This project’s overarching aim is to leverage the latest advancements in Silicon Carbon (SiC) semiconductor technology to develop high-efficiency and reliable solar photovoltaic-battery energy storage system (PV-BESS) for critical loads. Such compound semiconductors have low conduction loss, fast switching speed, and high operating temperature, which provides all potential for developing low-carbon PV-BESS. Challenges are that high-frequency switching of SiC semiconductors can increase thermal stress and create electromagnetic interference (EMI) due to their high-speed voltage transients (e.g. dv/dt over 10kV/us), affecting the reliability of the PV-BESS and lifespan of critical components such as capacitors and batteries. SiC semiconductors exhibit various material defects and variability, leading to variations and high non-linearities in their electro-thermal performances. Integrating SiC semiconductors into PV-BESS requires a better understanding of induced parasitic parameters and their coupling with components, including capacitors, inductances and gate drivers. To address these issues, the project has three research work packages (WP1-3): Develop accurate characterisation and modelling methods for semiconductor devices (WP1): Accurate SiC electro-thermal models and lifetime models will provide a new understanding of SiC semiconductors, which will be built to evaluate component efficiency and reliability under various environments. Integration optimisation of SiC-based PV-BESS (WP2): This involves studying and modelling the multiphysics coupling between SiC semiconductors and other components, investigation of induced parasitic parameters and system-level topology design of PV-BESS to reduce power conversion stages, thus improving overall efficiency and reliability. Validation and operation optimisation of SiC-based BESS in various operation conditions (WP3): This will investigate integration strategies and verify the benefits brought by SiC devices' advantages to ensuring the BESS’s high-efficiency and reliable operation in both normal and fault conditions. The main deliverables will include validated tools and a testbed for modelling and characterisation of SiC semiconductors (WP1), hardware-in-the-loop demonstrator for validating the SiC-based PV-BESS (WP2), and optimal operation strategies for PV-BESS (WP3). These will be useful to physics R&D institutions, renewable equipment vendors, and power system operators. The project will involve international partnerships with the University of Nairobi, with support from Scottish Power Energy Networks (SPEN) and Toshiba Europe. Researchers involved will benefit from the unique collaboration and training, and the project will help Africa build new physics research capacities in the renewable energy and semiconductor sectors. The project output will boost the PV-BESS’ energy conversion efficiency by 1%–2%, and extend their mean-time-between-failures by 20%. Developed compound semiconductor technologies will have a wider impact across applied industries, including electrified transportation sectors, robotics and aerospace. The integration and BESS technologies can be extended to generic low—and medium-voltage energy systems.
Frugal Innovation for Societally-Important Challenges in Africa (FISICA)
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Historically, Physics is seen to be a key driver of novel techniques and instrumentation that draw on our advances in scientific understanding. Such instrumentation often plays a critical role in helping to solve societal challenges in areas such as agriculture, climate change, energy generation, and healthcare. Sadly, much state-of-the-art technology is prohibitively expensive for developing countries, limiting its adoption. Here, we will bring together partners from the UK and several African countries – Ghana, Rwanda, South Africa and Tanzania – to collaborate on developing cost-effective instrumentation. The two types of instrumentation to be worked on are a hyperspectral imager and a gamma-ray spectrometer: A hyperspectral imager is an instrument that can be used to analyse fine details of the light reflected by the leaves of plants in different parts of the visible or infra-red spectrum. The properties of this reflected light turn out to be very sensitive to the health of plants or crops. In this manner, a hyperspectral imager can be a major benefit to monitoring of crops and other aspects of agricultural development. A gamma-ray spectrometer is an instrument that is sensitive to gamma radiation. Gamma radiation is emitted from so-called naturally occurring radioactive material (NORM) found in certain rocks, minerals and soils. A gamma-ray spectrometer can both quantify the radiation and identify its origin. This project will begin with two workshops: one in the UK and one in South Africa. The workshops will be facilitated by experts in innovation to help the project partners co-create mini projects making use of the novel instrumentation to address challenges specific to their own localities, with a particular focus on issues such as agriculture and climate change. The project will deliberately challenge people to work in a highly interdisciplinary way and collaborate with other researchers well outside their immediate field of expertise. Impacts are expected not only in technology development but also from the field trials to be carried out with the novel instruments. The project will also lead to capability building and upskilling of significant numbers of early career researchers at universities and organisations across several Africa countries. The project builds on existing strong collaborations between the University of York in the UK and three Universities in South Africa: University of Pretoria (UP), University of the Western Cape (UWC) and the University of Zululand (UZ). Indeed, this new project will, in part, exploit earlier STFC investments (Funder Award Reference ST/S003118/1) that built the Modern African Nuclear DEtector LAboratory (MANDELA) at the two historically disadvantaged universities, UWC and UZ.
Stability of the South African Power Grid ---A data-driven Statistical Physics-based Approach
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
South Africa (SA) primarily relies on coal-fired power plants for its electricity supply. At least 12% of the population does not have access to power and roughly 10% cannot adequately afford electricity, particularly in rural areas. There is a particular challenge with reliable electricity supply in SA, as currently there is inability to deliver sufficient power according to the country’s demand. This has led to the implementation of rolling blackout load shedding events across the country. Load shedding has marked deleterious societal effects. In 2021, the citizens and industries of SA were afflicted by a lack of power and periodic load shedding for over 48 days of the year. There are also unplanned outages (known as non-technical losses) for parts of the network. During electricity outages, people and households typically use Diesel generators (if they can afford them), others simply remain without power. The use of Diesel generators during load shedding periods has severe detrimental effects, in financial, environmental, and health terms. Diesel generators are also frequently used in other African countries if there is no reliable connection to the power grid. Our project aims to better understand, model, and mitigate the above load shedding situations in SA, working towards sustainable solutions (alternatives to Diesel generators) with no Carbon emissions that can be afforded by all. The overall aim is to model, understand and improve the stability of the African power grid using methods from statistical physics. To model the South African power grid as a whole, we will be using cutting-edge research methods in statistical physics modelling of complex systems, data-driven analysis and machine learning. A central aspect of our work plan will be the analysis of frequency fluctuations in the main grid, the control of microgrids, and the analysis of wind energy statistics, working towards future implementation of zero-emission generators based on wind power, solar panels, and batteries. We will model and analyse the overall demand patterns of electricity consumers in SA in a data-driven way, to finally arrive at practical solutions and concrete mitigation strategies. We aim at solutions that are particularly suited for the poorest in SA. At the same time our approach will contribute to lowering the Carbon footprint of SA in the long-term. The main general objectives of our proposal are as follows: Model and forecast the stability of the SA power grid. Model the fluctuating electricity demand of individual households in a data-driven statistical-physics inspired way. From a complex system point of view, take up the challenge of modelling a system where demand and supply don’t match. Model microgrids that use Diesel generators and/or zero-emission generators during load shedding periods. Measure frequency fluctuations in the grid and feed the data into theoretical statistical-physics based models. Develop statistical physics models that capture the essential features of the dynamics. Using neural nets, predict wind power fluctuations in SA. Prepare the ground for long-term mitigation strategies and a reliable electricity supply for all (in particular the poorest communities in SA) during load shedding periods and beyond, based on wind power, photovoltaic systems, and batteries. Foster new scientific collaborations between SA and the UK, dealing with statistical physics-based modelling of power grids. Work together towards a long-term strategy where power is provided in a reliable way, at the same time reducing the Carbon footprint of SA.
