Ayrton Fund

Ayrton Fund is sponsored by Department for Energy Security and Net Zero, Department for Science, Innovation and Technology, and Foreign, Commonwealth & Development Office. Supports clean energy research, development, and demonstration to accelerate the clean energy transition in developing countries.

The Ayrton Fund supports clean energy research, development and demonstration (RD&D) to accelerate the clean energy transition in developing countries.

Department for Energy Security and Net Zero , Department for Science, Innovation and Technology and Foreign, Commonwealth & Development Office Get emails about this page The UK government has committed up to £1 billion through the Ayrton Fund to support clean energy research, development and demonstration ( RD&D ) between April 2021 and March 2026. This is part of the wider UK commitment to tackle climate change and spend £11.

6 billion of International Climate Finance (ICF) over the same period. The Ayrton Fund aims to accelerate the clean energy transition in developing countries, by creating and demonstrating innovative clean energy technologies and business models. It will demonstrate UK leadership and expertise in cutting global emissions through world-leading innovations.

It seeks to make clean energy options the most affordable, accessible and attractive options in developing countries. This supports Sustainable Development Goal (SDG) 7 (Affordable and Clean Energy) and SDG13 (Climate Action). It also supports the ambitions of important initiatives such as the COP26 Glasgow Breakthroughs and Green Grids Initiative .

Specifically, it supports RD&D around 3 themes: lower-cost, flexible clean energy supplies suited to the resources of developing countries super-efficient demand via innovative services, processes and equipment meeting the needs of poor consumers and enterprises smart delivery systems and resources to manage variable clean energy and reduce the costs of delivering reliable clean energy The Foreign, Commonwealth & Development Office ( FCDO ) , the Department for Energy Security and Net Zero ( DESNZ ) and the Department for Science, Innovation and Technology ( DSIT ) jointly manage the Ayrton Fund.

They do this through a portfolio of ongoing, new, and scaled-up clean energy platforms and programmes, including thematic challenge programmes, and country and regional demonstrators.

Ayrton thematic challenges target technology priorities that are important for the achievement of SDG7 and SDG13 , including: sustainable cooling for all industrial decarbonisation inclusive energy and leave no-one behind Use the Ayrton Fund Explorer Tool to find more information about the fund’s programmes and projects across these thematic challenges.

These include, for example: Transforming Energy Access (TEA) This FCDO research and innovation platform supports early-stage testing and scale-up of innovative technologies and business models that accelerate access to affordable, clean energy. It helps poor households, enterprises, and social institutions in developing countries in Sub-Saharan Africa, South Asia, and the Indo-Pacific.

Climate Compatible Growth (CCG) This FCDO research and innovation platform develops evidence and global public goods to help countries develop and implement economic strategies and plans. It also works on policies to attract investment into low-carbon growth opportunities across various sectors, including grid-scale energy and transport.

Accelerate to Demonstrate (A2D) This DESNZ Facility aims to accelerate the commercialisation of innovative clean energy technologies in developing countries, in critical minerals, clean hydrogen, and cross-cutting energy transitions themes, such as industrial decarbonisation and smart energy.

Clean Energy Innovation Facility (CEIF) This DESNZ platform aims to accelerate the commercialisation of innovative clean energy technologies in developing countries in key themes. These include industrial decarbonisation, sustainable cooling, smart energy, and energy storage. Ayrton Challenge Programme This DSIT programme funds a portfolio of research projects that seek to accelerate the clean energy transition in developing countries.

It supports both the development of innovative technologies, and the generation of knowledge needed for long-term sustainable change. Global Challenges Research Fund (GCRF) This DSIT research and innovation Fund supports UK and international researchers and innovators to address important issues affecting developing countries, including access to clean energy. UK Research and Innovation (UKRI) run GCRF Ayrton Fund activities.

Modern Energy Cooking Services (MECS) This FCDO programme develops clean cooking research products and supports clean cooking scale-up and innovation. Through a consortium of world-leading UK universities and innovators, it aims to support the transition from biomass to genuinely clean cooking fuels in developing countries.

Low Energy Inclusive Appliances (LEIA) This FCDO research and innovation programme focuses on improving the efficiency, performance, and availability of electrical appliances and solar technologies for off-grid and weak-grid settings. At the same time, it aims to lower their cost for consumers, particularly in Sub-Saharan Africa, Southeast Asia, and the Indo-Pacific.

Catalysing Agriculture by Scaling Energy Ecosystems (CASEE) This FCDO research and innovation project supports innovative energy and agricultural technology businesses in Sub-Saharan Africa and South Asia. It aims to strengthen energy, agriculture, and food systems, boosting the productivity, income, and resilience of smallholder farmers.

It is part of the wider Strengthening Impact Investment Markets for Agriculture (SIIMA) programme and follow-on Scaling Agriculture Investment in Digital, AI and Innovation (SAIDAI) programme. Africa Regional Climate and Nature (ARCAN) This regional FCDO programme supports the World Bank’s Sustainable Renewables Risk Mitigation Initiative (SMRI) and the Africa Development Bank’s Sustainable Energy Fund for Africa (SEFA) .

These initiatives are scaling-up proven renewable energy technologies and demonstrating the integration of energy storage, smart/mini-grids and new guarantee instruments. The programme contributes to sustainable and environmentally sound economic development and low carbon green energy generation and access across Africa.

Accelerating Smart Power and Renewable Energy in India (ASPIRE) This FCDO country programme supports India’s clean energy transition. It focuses on key areas such electricity distribution, e-mobility, industrial energy efficiency, solar energy, offshore wind energy, energy storage and green hydrogen.

This FCDO country programme is expanding rural household energy access by catalysing private sector innovation and investment and government support in Mozambique. It aims to increase domestic and business energy solutions through the supply of household solar, mini-grids, and improved cooking technologies.

Mitigation Action Facility (MAF) This DESNZ -supported Facility is a UK-German multi-donor fund that drives lasting policy and technology change in developing countries. It focuses on hard-to-abate sectors, offering high-value grants and technical assistance to projects in areas such as energy and transport.

Pacific Clean Energy Programme (PCEP) This FCDO regional programme aims to improve access to affordable clean energy in Pacific Island Countries by increasing investment into renewable energy. It includes a Regional Clean Energy Investment Fund that mobilises funding and supports local developers to build a pipeline of viable renewable energy projects.

It also includes the Papua New Guinea Clean Energy Investment Fund in partnership with Australia. This provides grants to civil society organisations to scale-up clean energy access in remote and marginalised communities not served by government systems. Pioneer Outcomes Fund (POF) This FCDO programme includes a £13.

5 million contribution to the World Bank’s Clean Cooking Fund. It seeks to drive private sector investment into the clean cooking sector by using outcome-linked financing to incentivise the innovation, adoption, and scaling of modern cooking technologies across Sub-Saharan Africa, South Asia, and the Indo-Pacific region.

Pioneering a Holistic approach to Energy and Nature-based Options in MENA for Long-term stability (PHENOMENAL) This regional FCDO programme supports innovations and investment in renewable energy, transport, hydrogen and low carbon industry in the Middle East and North Africa (MENA).
