Malta
Venture Round in 2023
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.
Electric Era Technologies
Series A in 2023
Electric Era Technologies specializes in AI-controlled battery storage systems for efficient operation of electric vehicle (EV) charging stations. Its PowerNode-OS platform ensures optimized and reliable charging across all PowerNode stations.
Natel Energy
Series B in 2021
Founded in 2005, Natel Energy designs, builds, and sells restoration hydro turbines for generating renewable electricity from moving water across drops. Its turbines can be installed in various settings, including retrofit of existing turbines, non-power dams, irrigation canals, and new stream reach developments. The company also offers digital services like HydroForecast, which uses satellite imagery and machine learning for hydrologic modeling and power generation forecasting.
Mainspring
Series D in 2021
Mainspring Energy, Inc. is a technology company based in Menlo Park, California, that specializes in developing linear generator technology for low carbon, dispatchable energy solutions. Founded in 2010 by three Stanford engineers, the company focuses on creating advanced prototypes that convert fuel into electricity through a unique, low-temperature reaction of air and fuel. This innovative approach allows Mainspring to offer generators that provide affordable, reliable electricity while significantly reducing carbon emissions compared to traditional electric grids. The company's mission is to address climate change and enhance energy accessibility, contributing to the development of net-zero carbon energy systems for the future.
