In the context of the European project, SMHYLES, C2C-NewCap is developing two supercapacitor modules to integrate an energy storage system with batteries to support the grid. These demos will be online in 2026 and are located in island of Graciosa (Azores) and Maia (north of Portugal). The supercapacitor systems are designed to control the grid’s peaks of supply and demand and provide a more robust control of the its frequency.

Compared to conventional solutions, these new storage systems are expected to have a 40 per cent lower carbon footprint, also thanks to novel recycling solutions, and a 20 per cent higher reliability and availability, which should make our renewables-based power grids more resilient.
