LightSail Energy

LightSail believes that a low-cost grid-scale energy storage solution holds the key to unlocking the true potential of increasingly competitive renewable energies, optimizing power grids, democratizing access to energy, and helping to make the world a safer and better place for future generations.

LightSail aims to produce the world’s cleanest and most economical energy storage systems. Compressing air creates heat energy. Until now, this was wasted, drastically reducing efficiency.

Their innovation: an elegant method of capturing this heat energy and regenerating useful energy from it. They inject a fine, dense mist of water spray which rapidly absorbs the heat energy of compression and provides it during expansion.
