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.

European Innovation Council
[EIC] Stage 2: EIC Accelerator Challenge
Objectives: The EIC Accelerator aims to support high-risk, high-impact innovations to create new markets or disrupt existing industries in Europe and globally. The program helps scale breakthrough technologies and deep tech innovations, particularly in areas where private investors may be reluctant to invest due to high risk. The EIC Accelerator is best suited for innovative companies with disruptive technologies that need funding to expand and enter global markets. Specific challenges: 1. Advanced Materials for Renewable Energy and Energy Storage System: - Supported start-ups and SMEs must d…
