About the Forum
The 2026 Forum will mark five years of the Ayrton Fund (2021–2026) — the UK Government’s flagship initiative advancing clean energy transitions in developing countries through strategic investment in the research, development and demonstration (RD&D) of innovative clean energy solutions, with a particular focus on Sub Saharan Africa, South Asia and the Indo Pacific.
The Forum will:
- Celebrate achievements and share lessons from the Ayrton Fund’s first phase, including its contribution to accelerating progress towards Sustainable Development Goal (SDG)7 (affordable, reliable, sustainable and modern energy for all) and SDG13 (climate action);
- Showcase latest progress in breakthrough clean energy innovations and delivery models emerging from the Ayrton portfolio, connecting technologists, entrepreneurs, financiers, and policy makers
- Help shape priorities and partnerships for the Fund’s next phase under the UK’s International Climate Finance (ICF) portfolio.
Sessions will be themed across the day, including: electrifying development, green industrialisation, powering inclusive growth, circular energy economies, green grids, and leaving no one behind.
The principal Forum will be held on Monday 22 June 2026.
