LightSail Energy

LightSail, founded in 2008, was initially developing a product focused on using compressed air to power a scooter. Their focus shifted to compressed-air power generators that could fit inside a shipping container around 2012.

Other energy storage competitors include Energy Vault, which develops gravity-based energy storage systems; Primus Power, which develops flow batteries; Vionx Energy, which develops flow batteries; National Renewable Energy Laboratory, which is developing high temperature, low cost thermal energy storage systems; Brayton Energy, which is developing a storage system combining thermal storage and a gas turbine; Form Energy, which is developing an energy storage system using a sulfur and water-based solution; Quidnet Energy, which is developing a modified pumped hydro energy storage system using sub-surface rocks; Echogen Power SystemsEchogen Power Systems, which is developing a storage system using carbon dioxide heat pump cycle to convert energy; United Technologies Research Center which is developing an energy storage system based on new flow battery chemistry; and Antora Energy, which is developing a thermal energy storage system using carbon blocks.
