Asegun Henry, an innovator and professor at MIT, says that energy storage is arguably the single most important technological problem we have to solve. He is developing and commercializing a new type of battery based on thermal energy conversion instead of the conventional electro-chemical reaction—a battery that’s been dubbed, “sun in a box.” He shares what it takes for a new technology to compete in today’s market and how his technology might be the gamechanger we need to decarbonize the power grid.
