## About

Established in 2023 and based in Edinburgh, UK, Exergy3 Limited, a spin-off from the University of Edinburgh operates as a manufacturing company that offers thermal storage to its clients to help them convert CO2 emissions to thermal energy. In April 2026, Exergy3 Limited raised GBP 10 million in seed funding from Axeleo, Bayern Kapital, Kibo Invest, Old College Capital, Zero Carbon Capital, Scottish Enterprise.

The firm develops and commercializes ultra-high-temperature energy storage technology that converts renewable electricity into thermal energy, supplying high-temperature heat for industrial processes and district heating systems. It also enables the storage of excess renewable energy during periods of low demand for later use. Exergy3’s system is scalable and adaptable for various industrial applications, to reduce carbon emissions and reliance on fossil fuels. 

The company will use the April 2026 funding to scale its high-temperature thermal energy storage technology for industrial heat, accelerate European market expansion, and support commercialization of systems that enable electrification and decarbonization of industrial processes.
