Cleantech & Energy grants
DESNZ, Innovate UK and Horizon Europe funding for the energy transition
DESNZ and Innovate UK run the largest energy-transition grant programmes in the UK, backed by Horizon Europe's Climate, Energy and Mobility cluster for genuinely transformational bets. Assessors are engineers and they will check your numbers, cost per kilowatt-hour, round-trip efficiency, capture cost per tonne.
