Heat
Zero-carbon heat at TWh scale
Large-scale heat consumers face an enormous challenge: they must decarbonize their operations, but securely, affordably and with minimal disruption. Unfortunately, most solutions proposed today are either too expensive, too risky, too intermittent, not secure enough, or create unacceptable interruptions in their operations.
Additionally, clients want to focus on their core business, and not divert time or precious capital to the energy business.
Thermaxa CASH solves all these problems with its affordable zero-carbon Heat as a Service, using secure local sources and simple drop-in solutions.

A different vision
EU industries and cities desperately need TWhs of affordable clean heat TODAY to remain competitive and fulfill their climate mandates. They simply can’t wait for new technology to be invented, take 20 years to de-risk, or end up too expensive (green H2).
We believe deploying bankable proven solutions with existing GW supply chains is the best way to deliver secure green heat at a climate-meaningful scale and timeframe.
