About Exergy3

Exergy3 is focused on a major challenge of our time: how to decarbonize industrial processes while still keeping economic practicality in view. Its answer is scalable, efficient, and cost-effective: ultra-high-temperature thermal batteries.

As a spin-out from the University of Edinburgh, Exergy3 combines leading academic research with entrepreneurial execution, turning technological innovation into industrial reality.

In March 2025, the company established its European headquarters at Königsplatz in Munich to expand into the EU market, bridge trade barriers, and open the business to European talent.

The Munich location is not a satellite office, but a second core base for the company. Over time, all business functions are expected to be represented there, from research and development to executive leadership.

Working at Exergy3 means joining a highly driven, international team tackling one of the most urgent issues of our time. The pace is fast, ownership is real, and the stakes are high in the best possible way.

If that kind of mission-led environment excites you more than it intimidates, you may be a strong fit.
