Andrew Bissell, a entrepreneur, was inspired by an article about climate change to create a solution to store solar power as heat, which could be used for household heating and hot water. He co-founded Sunamp with his wife, Susan Lang-Bissell, and developed a thermal battery that uses three compounds, including a food flavoring used in potato chips, to store and release heat. The thermal battery, called Plentigrade, can last up to 40,000 heating cycles, or over 50 years, and is designed to be used in homes where space is limited. Sunamp is generating revenue in the tens of millions and is expanding its presence in Europe and the US, with a goal of making it possible for everyone to use renewable energy, regardless of their living situation.
