Storelectric Ltd

Storelectric’s innovative forms of Compressed Air Energy Storage (CAES) enable renewables to power the grid stably, resiliently and affordably.

Each technology is a simplified configuration of existing operating plants, using off-the-shelf equipment to create electricity storage sized from 20MW to multi-GW, with durations of 4hours to multi-days, the most cost-effective and widely replicable technology at this scale. Plants have 40-50 year life and can be future-proofed for hydrogen, built with today’s technology, validated by numerous engineering multinationals.

Adiabatic TES (Thermal Energy Storage) CAES is zero emissions, 62-70% grid-to-grid efficiency depending on size, cheaper $/MWh than batteries.

CCGT CAES is (uniquely) retro-fittable to suitably located power stations. 50-60% efficient, much cheaper than other CAES, it reduces a power station’s emissions and adds storage- and flexibility-related revenue streams.

Hybrid CAES is CCGT CAES with thermal storage: considerably more efficient, and longer duration.

All technologies deliver more real inertia and related stability services than an equivalent-sized power station, 24/7, and over 6x real reactive power and load. Profitable without subsidy where regulations permit. Low levelised cost. Grid-scale back-up to intermittent and baseload generation, enabling a Net Zero grid. Enormous additional synergies if associated with renewable and nuclear generation. Potential locations are plentiful world-wide
