Demonstration of thermal energy storage solutions for solar thermal plants and systems

Funds demonstrations of thermal energy storage that let concentrated solar and solar-thermal plants deliver power on demand.

ClosedEuropean CommissionEU

This Innovation Action from the European Commission funds demonstrations of thermal energy storage that let concentrated solar power or solar-thermal heat and cold systems deliver power on demand, cutting the cost of stored heat or energy. The portfolio-balance guarantee has an escape hatch the headline description doesn't spell out: if a single proposal addresses both concentrated solar power and…

The Commission wants demonstrations of thermal energy storage for either concentrated solar power or solar thermal heat/cold systems, aiming to cut the cost of stored heat or energy and improve the reliability and financing case for dispatchable solar thermal plants.
