GoHubs Mozambique Green Fishing and Cold Chain Hubs
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
GoHubs Mozambique is a transformative network of solar-battery microgrid hubs serving the artisanal fishing sector in coastal communities of Mozambique. The primary objective of GoHubs is to provide smart reliable renewable energy solutions, infrastructure and equipment to unlock market access, reduce fish losses, and bolster the local fishing sector. The artisanal fishing industry plays a crucial role in Mozambique, accounting for 90% of the total catch and with over 15% of households depending on it for their livelihoods. However, inadequate energy and transport infrastructure in coastal areas restrict the availability of resources such as ice, cold storage, and access to non-local markets. These limitations lead to significant fish losses and reduced incomes within the sector. To address these challenges and create new opportunities, GoHubs introduces a pioneering business model that combines significant technological and commercial innovations. From a technical perspective, GoHubs integrates energy-intensive operations like ice production, cold storage, water pumping, and electric refrigerated transport into an integrated hub, powered by an on-site solar-battery microgrid. Smart control and load management system, ensures a reliable and efficient power supply and optimises across the critical loads. The entire systems is also integrated onto a single monitoring platform to simplify operations. From a commercial standpoint, this bundling approach ensures that a continuous reliable cold chain from boat to market is effectively and sustainably established. Furthermore, this strategy facilitates economies of scale, resulting in lower unit costs for ice and services. GoHubs not only sells ice and cold storage services but also supports the trading of local fish, providing electric refrigerated transport to larger markets. The business model also enhances resilience by diversifying revenue streams, and by including electric vehicle charging reduces the impact of volatile fossil fuel costs on transportation. By providing ice and services instead of selling energy units, GoHubs mitigates the uncertainty associated with the current regulatory environment. GoHubs is a pilot deployment in Inhambane Province on a public-private partnership model with a community fish market. GoHubs expects to improve the livelihoods of the fishing sector workers and the broader community through improved catch quality, better and reliable market access, and reduced losses and wastage and replicate the model across Mozambique and other countries where renewable and reliable cold chain can unlock green growth.
An Open-Water Demonstration of INWave Wave Energy Converter Power Plant in Vietnam
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
INWave, the onshore-type Wave Energy Converter, is suitable for shoreline and remote islands. IWES's business goal is to offer clean, affordable and reliable Wave Energy Converters, with a Simple, Scalable & Sustainable technology. The technology has been proven to be feasible at prototype level since 2015, with a Seal of Excellence award by European Commission's Horizon 2020 programme in 2016, MEA (Marine Energy Alliance) award achieving TRL 6-7 evaluation in 2019, and a successful Energy Catalyst Round 9 funding in 2022. INWave provides the unique approaches of: deploying the power generation device onshore, harvesting wave energy from the shallow nearshore water, and using the whole range of wave movements. It ensures durability, safety and affordability. This reduces costs and time, enabling sustainable supply for the smaller scale local market needs. INWave innovation brings access to clean and affordable energy to the coastal community. It is competitive with expensive diesel generators, which are commonplace in fishery harbours and remote coastal areas in Vietnam. In particular, in remotely scattered islands in the South China Sea (Vietnamese East Sea), meeting energy demand is very expensive relying on fossil-fuel based energy, due to the logistic and volatile cost conditions. Diesel generators, kerosene lamps and burning wood cooking are common occurrences. There is huge potential ocean energy in Vietnam and in Asia-Pacific Ocean countries that could be utilised to generate electricity. One of the beneficiaries of planned wave power plants are coastal communities from relatively traditional fishery, farming and aquacultural communities. This innovative technology will provide them with increased energy security at a lower cost and with largely reduced CO2 emissions. The object of the proposed project is to complete and demonstrate the successful construction and commissioning of a Wave Energy Pilot Plant in the selected site in Vietnam. Through appropriate project assessments, the pilot power plant is expected to yield significant impacts in technical, social, economic, and environmental aspects. The proposed innovation to be installed in a remote island is an onshore-type WEC technology. Onshore, because as opposed to most other offshore WECs under development, its power generation unit is located on the shoreline and not at sea. This design enables system stability, significant cost reductions and makes clean energy infrastructure investment more affordable. We will maintain collaborative partnerships with all relevant government stakeholders, which ensure project adequation with the country's sustainable development targets and regulatory framework, such as PDP8.
BioEnergy Powering Agriculture and Rural Livelihoods Enhancement- BEPeARLe
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
According to the International Energy Agency, 770 million people worldwide do not have access to electricity today, primarily in Asia and Africa. Energy insecurity is one of the biggest problems in rural areas because poor grid infrastructure and connections are a significant contributor to the lack of access to power, which impedes socioeconomic development. Rural electrification will not only spur economic growth but also narrow the urban-rural divide. How can we address energy infrastructure on a budget when high-capacity batteries are (mostly) prohibitively expensive? Solar photovoltaics (PV) is already a tried-and-true method of producing electricity off-grid. Our vision is to provide all three components of the energy trilemma - affordability, reliability, and sustainability of clean energy access - to marginalized communities in five target countries -- Botswana, Cambodia, Nigeria, Uganda and Zambia, via our Agrivoltaic Solar - Biomass Gasification - Biogas Hybrid system. Mandulis, through its zero-waste circular economy model, generates clean energy solutions from waste, enabling smallholder farmers to access clean electricity for powering their households and businesses, clean cooking fuel, energy-saving cookstoves, agricultural processing services, and soil enhancers. The uniqueness of our circular economy model, leveraging on and revalorizing residues and byproducts of the process, makes all these goods and services affordable, reliable, and sustainable for smallholder farmers, having a great positive impact on poverty alleviation, climate resilience, and biodiversity protection. This project will demonstrate the economic benefits that can be achieved by integrating agriculture and energy. As a core business objective of Mandulis Energy, bringing these two sectors together will foster cross-sectoral engagement, stimulate business opportunities, and partnerships between smallholder farmers in the targeted areas with larger economic players. It will also develop locally the skills necessary to put these multifunctional technologies into use and keep them maintained. To disseminate knowledge, comprehend end-user requirements, and develop a supply-chain integration strategy, we will work directly with local communities, energy developers, and SMEs in all target countries as we implement: 12 PV - biomass gasification - digestion systems in Uganda (6 sites - 100 kW, 1 site - 500 kW), Botswana (1 sites - 100 kW), Nigeria (1 site - 100 kW), Zambia (1 site - 100 kW) and Cambodia (1 site - 100 kW), generating low carbon, reliable, affordable and productive renewable energy to drive post-harvest processing, clean cooking fuel and biofertilisers.
Project GANESHA - Getting power Access to rural-Nepal through thermally cooled battery Energy storage for transport and Home Applications
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Project GANESHA focusses on development, manufacture and implementation of an innovative battery module solution for powering Nepal rural-based small passenger vehicles and off-grid low-power home energy systems. Solar-power installations will be constructed to pilot our innovation in two seperate rural-Nepal pilot sites with marginal-/zero-power access. Our consortium including three-UK and two-Nepal organisations, was formed to assist solution-development for commercial challenges faced by the Nepal Electric Vehicle Institute (NEVI) in achieving its ambition to provide Nepal-wide zero-carbon public-transport/power access. NEVI were established in the mid-1990s when growing urban-population densities led to exponential-increase in urban-internal combustion engine (ICE) vehicle registrations/polluton. NEVI were pioneers in retrofitting Nepal-ICE-rickshaws to EV, and developing battery-solutions to power these vehicles. It rents batteries to marginalised-/low income-communities through its its affordable model, to facilitate their independant-income-generation (60% of its work-force being female). Limitations of Nepal's rural-/urban-location power grid/distribution restrict EV-rollout across the country. NEVI are forced to depot-recharge EV-rickshaws during night-periods when power-demand is low and risk of powercuts are minimised. Limited depot-space and grid-power restrictions limit EV-rickshaws numbers NEVI can provide each location's public-transport market. NEVI wish to access solar-power to charge vehicle battery packs and envision a removable solution simlar to products currently marketed in India and Sub-Saharan Africa to expand its service to rural-communities where solutions are most needed (aligning with its original mission). However, current module-products are recharged at low C-rates and require large capital-investment. To supply a public-transport EV-fleet NEVI would require large module-stocks and high-area solar-arrays. Our projects innovation/case study-sites resolve this dilemma. A new module will be designed, manufactured, and mobilised incorporating PAK-Engineering Ltd's robust-/lightweight-heat exchanger technology. PAK's system facilitates high C-rate charging and design-versatility enabling PAK to adapt/optimise its function to suit multiple environmental-conditions. EPT Ltd will design module-incorporated state-sensor/communications technology so module-function is optimised, and location tracked when in use. Gamma-Meon Ltd will design, adapt and incorporate a specilised payment systems platform that EV-rickshaw operators and users will use to access NEVI services. Our solution will reduce mentioned-capital investment-requirments, and enable rollout to two rural-communities with marginal-/zero-power access in project-timescales. NEVI via partneship with Nepal-famed gender/social-equity pioneer 3 Sisters Trekking Group will construct two rural-solar arrays for charging our-modules, for powering 8-10 EV-vehicles adapted to location-conditions, and provide home-energy-kits for lighting and small-device charging for imroving life-quality in these locations.
Project RICE (Renewable, Inclusive, Carbon-positive Energy)
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
PROBLEM Modern agriculture is so critically dependent on fossil fuel inputs that they often outweigh energy outputs from the food produced. Hence modern farming has been described as "the use of land to convert oil into food". Undoubtedly, diesel-powered mechanisation has greatly reduced backbreaking drudgery for countless millions of farmers, and conversion of natural-gas into ammonia/nitrogen fertilisers is currently feeding a third of humanity. Nevertheless, the downsides are painfully obvious: Input Costs: Centralised production/distribution of fossil fuels mean farmers in remote areas across Africa and Asia often pay more than double for diesel-fuel/N-fertilisers. Those who cannot afford them are stuck in cycles of hard labour/low-yields/poverty. Those who can afford them lose around 60% at point-of-use(waste-heat from engines, or leaching/volatilisation from N-fertilisers). Food Prices: Food uses around a third of all energy globally, so when fossil-fuel prices rise, food prices follow, creating political instability and hardship for the world's most vulnerable(urban-poor and farmers in developing countries). Greenhouse Gas(GHG) Emissions: Agricultural emissions continue to rise, accelerating climate change, disproportionately impacting farmers in developing countries. VISION Development of efficient agricultural technologies powered by renewable energy to lower emissions whilst increasing farmer productivity and profitability in developing countries. Our focus is on the world's number 1 food crop: rice. Known as a "Poverty Crop"(low-margins for smallholder-farmers). Responsible for 48% of all crop GHG emissions. 91% of rice is produced/consumed in Asia. Straw Innovations("SI") (British SME operating in the Philippines) has pioneered a suite of technologies for collecting rice straw at harvest-time, avoiding field-burning/rotting that accounts for almost half of rice emissions. In this project, they will convert their "straw-catcher" machine to run on solar-PV electricity/batteries instead of diesel. Takachar(multi-award-winning Indian SME) has developed a cost-effective mobile biochar production unit that can transform rice straw from a major pollutant into a vast carbon sink. They will make a 10x scaled-up version and send it to SI, who will tap the waste process heat for the first time to dry rice, instead of diesel/kerosene. The char will then be returned to the farmers' fields as a more efficient fertiliser/soil-amendment, incorporated by the same SI electric "rice/straw-collectors" that harvested it. SI will also send their machines from the Philippines to India mid-project and the two countries will test out different business models for farmer adoption/benefit. Aston University(home of SUPERGEN Bioenergy Hub) leading sustainability specialists will invite stakeholder feedback and also calculate GHG savings from the new system.
Solar And Biogas Off-grid Power (SABOP) for Rwenjeru Agrotourism and Demonstration Farm, Mbarara, Uganda.
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
In this project, we will integrate of 2 well-established technologies (solar photovoltaic power and biomethane from biodigestion of waste biomass) to create a 24-hours' all-weather electricity supply minigrid that will tackle the colossal lack of access to energy in Uganda (particularly Rwenjeru Agrotourism and Demonstration Farm). Also, we will implement a renewable milk chiller as a productive use of energy at Rwenjeru. Furthermore, we will conduct a market analysis and develop a business plan for the viable and affordable deployment of the project outcome and for future scale-up beyond the project. Our waste-to-energy anaerobic digestion system will help to process food and agricultural waste that will otherwise pollute the environment, into clean renewable energy (24hrs) for an agrotourism business and \>1,000 farmer's household. By performing initial socio-economic appraisal, we will access the affordability of potential end-users and the viability of the SABOP energy platform. We will leverage on the intrinsic waste-to-energy approach of the SABOP system to match the affordability of Ugandans. The implementation of a smart minigrid allows us to accurately measure loading and generation capacity of SABOP and to effectively plan for expansion into neighbouring communities. We will engage with local and national stakeholders to ensure buy-in and share outcomes from the project to improve energy policy in Uganda. The use of biomethane as an alternative to gasoil is expected to improve local air quality, with regards to NOx and particulate matter. We will reduce Rwenjeru's dependence on highly polluting diesel and petrol powered electricity generators. By generating electricity with solar power instead of fossil fuels, we can dramatically reduce greenhouse gas emissions, particularly carbon dioxide (CO2). Our stakeholders and community engagement (workshops, social media, and flyers) will increase environmental awareness and prompt end-users to be more resource efficient in other parts of their daily life. Reliable electricity supply from the SABOP system will improved street and community lighting which will enhance security in Rwenjeru. By increasing the productivity and profitability through energy access, as well as providing cheaper biofertilizer to farmers (76% women), households will be able to improve the quality and quantity of food in the homes with positive impact on the general health and well-being of people.
Development of a HIGH Capacity FLEXible Energy Storage System for Mini-Grid Application in Sub-Sahara Africa (High ESS)
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
This collaborative project will develop and demonstrate a new technology (HIGHFLEX) that consists of a high-capacity flexible energy storage systems (HIGHFLEX ESS) integrated with innovative Battery Management System (BMS); Power Conditioning Unit (PCU) and intelligent monitoring and performance management system (Digital Twin) for mini grid applications in hot climates. The new technology is a portable and scalable system that facilitates: Quick development of mini grids in SSA. Storage of high-capacity energy generated from clean power sources during peak hours for off-peak utilisation. Delivering reliable and affordable power system through innovative solutions e.g., Digital twin, second life battery, real-time performance management and heat control system. The project's vision is to rapidly accelerate access to affordable off-grid electricity from clean energy sources in SSA. The project taps into the expanding global mini grid markets to offer affordable energy access for social mobility and inclusion in SSA communities not served by main power grids. HIGHFLEX will facilitate steady supply of electricity to rural and unserved areas and reduce energy access gaps between rural and urban communities in SSA where inaccessibility to affordable electricity is one of the main drivers of poverty to over 600 million people. This project has chosen Nigeria as a case for deployment of HIGHFLEX technology because of its over 200 million population and majority of its rural population (48% of its total population) do not have access to affordable and low carbon electricity. The project addresses barrier (access to electricity) to adoption of advancements in healthcare system; developing new technologies for agriculture, commerce, education; and entrepreneurship. HIGHFLEX makes it possible to deliver low carbon electricity to unlock sustainable economic development in SSA communities. This will empower women and children to lead more productive lives and have a better wellbeing. This will in turn encourage gender equality by learning digital and modern skills, which gives girls and women equal access to education, healthcare and enterprise. Furthermore, access to clean energy via mini grid will reduce crime and social unrest, since majority of the population would be productively engaged (Bloomberg 2020). This will lead to improved human security and cohesive communities and societies driven by mutual objective for sustainable development. HIGHFLEX will accelerate access to affordable and low carbon clean energy from bio-diesel, solar and wind (SDG 7), which lower environmental impacts from continued use of diesel-powered generators in Nigeria (world's leading generator consumer) to combat climate change effects (SDG 13).
Off-Grid Renewable Energy Production and Storage with Organic Rankine Cycle, Solar and Waste (RESORCS)
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
According to the International Energy Agency, around four percent of the world electricity supply comes from solar electric cells. Solar energy is abundantly available in South Asia and in Sub Saharan Africa that is not harnessed nowhere near its full potential. The conventional technologies that harness solar energy are solar thermal and solar electric cells. Solar electric cells have a low conversion efficiency compared to solar heating cells and other thermal based energy conversion methods, for example an IC engine. Despite having a recycling efficiency of around 95%, recycling of solar electric cells is currently an expensive process. RESORCS project aims to design, construct and test an off-grid renewable energy production technology with a novel high output Rankine engine, local waste and solar energy harnessed with a concentrated solar collector. A concentrated solar collector can collect thermal energy efficiently and relatively cheaply. Collected thermal energy is used to propel a Rankine Cycle engine based rotary turbine generator to generate electricity. Thermal energy collected can be boosted using thermal energy produced with waste combustion and bio-gas generated using waste. This hybrid combination can produce high grade thermal energy that will also increase thermodynamic efficiency of the prime mover, in this case, the FeTu turbine. Thermal energy collected during day is stored in a thermal energy reservoir that can be regulated based on demand. Electricity generated can be used directly, fed to the grid or stored in a battery bank for night time use or during high demand. It can also be used to power sustainable clean transport systems such as electric cars. The system can be used either as a standalone application or a grid connected system. The system is suited for a cluster of households or a small-scale enterprise. In summary, the project aims to: design and optimise a concentrated solar collector system with environmentally friendly materials and technology for optimal efficiency; develop a thermal energy storage system and a Organic Rankine Cycle engine based turbine generator which is suitable for the concentrated solar collector system; design electricity generation and control system with the concentrated solar system Stirling engine generator with grid connectivity; design and integrate a waste combustion system to boost energy; prototype the combination system and test its performance in different modes of use; and investigate the design and impact of the system, pre and post design and construction
Piloting Basic Solar Energy Grants for Equitable Access to Energy
DEPARTMENT FOR SCIENCE, INNOVATION AND TECHNOLOGY
Like many emerging markets, South Africa has a fast-growing urban population, resulting in the proliferation of informal settlements on land often unsuitable for grid electrification. Nevertheless, under South African law, municipalities have a legal obligation to provide basic services, including energy, to all households but prioritising the poor. While existing national policies do allow for alternative (off-grid) energy services, these policies were not initially intended for urban informal settlements and are thus not fit for that demographic. A number of municipalities are thus exploring how to develop their own policies to meet this need. For example, the City of Cape Town is considering implementing a grant for eligible low-income households that do not have grid electricity. The monthly grant could be put toward an energy service of each household's choice. An advantage of such a grant is that it would provide affordable and varied options for consumers, and would stimulate innovation and competition amongst potential service-providers. Before implementing such a policy the city is seeking evidence to help establish an optimal grant-value that ensures a high level of inclusivity. iShack and Zonke Energy have been providing off-grid solar energy services (via Solar Home Systems and Solar-Towers, respectively) for a number of years in various informal settlements around Cape Town. They have tested a range of financial and operating models, and have shown conclusively that for the South African informal settlement context, private enterprise alone cannot fill the gap of energy access due to a lack of affordability. Thus, some form of state support is needed. In this project a Basic Energy Grant (funded by Energy Catalyst Round 10) will be implemented in one large community in order to demonstrate its effect on inclusivity, as well as build the case for viable business models. iShack and Zonke will collaborate to provide a choice of basic solar energy services. The project will run for two years, during which each participating household will have the benefit of the grant, which they can use towards the purchase of a Solar Home System or access to Solar-Tower electricity. A programmatic community engagement element will support a co-productive relationship with the community as well as promote energy democracy and capacity building, gender equality and inclusivity. Progress and outcomes will be monitored by Future Advisory Ltd who will conduct communications to disseminate the results of the pilot to relevant stakeholders, in particular to municipalities.
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.
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.
