AirLoom Energy develops wind energy technology that uses lightweight wings operating on a track to capture wind. The design aims to deliver the same amount of energy as conventional turbines at a fraction of the cost, enabling low-cost utility-scale wind energy. The system uses multiple small airframes on a slender oval track with downwind forces supported by a bridling system, and the configuration can be adjusted depending on the landscape, allowing clients to harvest wind energy in cost-effective and quicker ways.

Fourth Power specializes in utility-scale thermal battery storage solutions. It converts renewable energy into a reliable on-demand power source, addressing grid needs while facilitating the transition to decarbonized infrastructure.

Malta is a developer of industrial-grade, grid-scale electro-thermal energy storage technology. The system captures energy from wind, solar, and fossil generators, converts electrical energy into thermal energy by creating a temperature difference, stores heat in molten salt, and reconverts it to electricity with a heat engine to be dispatched to the grid when needed. The technology enables long-duration energy storage, helping mitigate wind and solar curtailment and improve the matching of generation and demand, addressing bottlenecks in distribution and transmission and supporting affordable, reliable electricity on demand. Founded in 2018 and based in Cambridge, Massachusetts, Malta's solution targets grid operators and energy players seeking to balance supply and demand with grid-scale storage.
