Breakthrough Renewable Energy Technologies

Funds high-risk renewable energy concepts that prove technical feasibility at TRL 4–5 and outperform current commercial options.

ClosedEuropean CommissionEU

Europe needs renewable energy options that can change the economics and environmental performance of the energy system, not only incremental improvements to established products. This topic backs high-risk, high-return concepts while requiring credible evidence on impacts, viability and public trust.

Research can address catalysts, renewable energy storage other than batteries, hybrid generation

Research can address catalysts, renewable energy storage other than batteries, hybrid generation systems, heating and cooling, renewable fuels, direct solar fuels, solar-driven chemical processes or direct use of renewable sources. The concept must establish technical feasibility through a robust methodology and reach TRL 4–5.
