From Theory to a Successful Proof of Concept

Malta’s system is built upon well-established principles in thermodynamics, storing energy as heat (in molten salt) and as cold (in a chilled liquid). The idea is the brainchild of a Nobel Prize-winning Stanford University physics professor, who theorized the fastest way to transition to a decarbonized electric system is to integrate existing technology and supply chains. Malta was incubated at X, Alphabet’s Moonshot Factory, which identified the Malta system as a product that had the potential to unlock a wealth of inexpensive clean energy to address global energy demands. The team at X designed and tested individual system components and determined the Malta technology can work in the real world at a competitive price-point. Malta was formed as an independent company, outside of Alphabet, in December 2018.

Today: Acceleration

Today Malta is in advanced discussions with a more than a dozen utilities in Europe, and the Americas over plans to deploy Malta’s long duration energy storage technology. As the urgency of the energy transition grows, interest in Malta’s ready-to-market, thermo-electric energy storage solution has skyrocketed. Meanwhile, Malta’s talented scientific and engineering team are establishing, testing, and refining rigorous design standards and associated supply chain relationships to prepare the company to scale rapidly over the next three-to-five years. In 2022, Malta’s board issued a directive to management to find, hire and unleash the best and brightest available talent in energy, business and tech. A quick scan of recent Malta news shows this directive is already fully in action.

We’re focused on helping to build a more sustainable future.
