About Malta Inc.
Malta Inc., recently named to TIME Magazine’s World’s Top GreenTech Companies and America’s Top GreenTech Companies 2025, is advancing a new standard in long-duration energy storage with its proprietary Malta Steam Energy Management and Storage (Malta SEMS) system. Powered by a high-performance heat pump and steam as a working fluid, Malta SEMS stores electricity as thermal energy in molten salt and reconverts it into power and heat on demand. The system provides a flexible, cost-effective solution for storing energy from 8 hours to several days at grid scale, helping decarbonize hard-to-abate sectors while supporting grid reliability.
Originally incubated at X, Alphabet’s Moonshot Factory, Malta’s technology is built on proven industrial components and widely available materials—enabling rapid deployment, lower cost, and minimal environmental impact. The system can be deployed as a standalone asset or integrated into existing energy infrastructure, including repurposed fossil-fired plants, providing synchronous generation, dispatchable power, and medium-grade heat for industrial and district heating applications. With Malta SEMS, the company offers a future-proof platform for energy storage and flexible power and heat delivery—ready to meet today’s operational challenges and decarbonization goals.
