Whitepaper: Cost benefits of flexibility in electrification
Buying electricity when its cheap and shifting these low prices throughout the day is what makes electrification cheap. From 30% to 150% can be saved on wholesale electricity when using the Kraftblock storage instead of direct electrification. Read more on our whitepaper.




Kraftblock’s innovative thermal battery offers large-scale, long-duration heat storage. This empowers industries to use renewable energy without the disadvantages of volatility. Kraftblock supplies steam, hot air, thermal oil, or hot water at temperatures between 50 °C and 1,300 °C. It also allows you to increase energy efficiency through heat recovery, to generate power from heat and to optimise CSP.
As Tempelman CEO, Eneco
“Kraftblock is the kind of solution we need to scale up and repeat because it makes a huge impact in a relatively short amount of time.”

Kraftblock is on a mission
to decarbonize the industry.

The global climate crisis is progressing fast and devastating. The biggest lever for to slow the progress is to decarbonize the energy system. To use cheap and volatile sources like wind and solar, to transition heavy and hard-to-abate industries that run on high-temperature, a linking puzzle piece is needed: a unique energy storage. This is what we set out to made. Learn more about our journey and how you can become a part of our valuable team.
