Electrified Thermal Energy Storage (ETES)

Flexible Power-to-heat up to 1,200 °C

Replacing fossil fuels at industry scale – from 50 °C to 1,300 °C
‍
Renewable electricity and Kraftblock are the most cost-efficient ways to replace fossil fuels for industrial heat generation. The thermal battery uses electricity from cheap times and makes it available throughout the day, eliminating volatility and providing energy security. The electrification system using power-to-heat provides process heat as steam, air or thermal oil from 50 °C to 1,300°C.

How it works

Power-to-heat

At times of low prices, electricity from the grid or surplus power from own sun or wind power plants is converted into heat with 98% efficiency using a resistive heater.

Thermal Energy Storage

The heat is stored in the thermal battery from minutes to several days. The sustainable material provides high energy capacity.

Discharging process heat

The stored heat is discharged as air, steam, thermal oil, water or gas and adapted to the right temperature to supply the process. Including this step, the whole system has a round-trip efficiency of over 95%.

Electrification with Kraftblock's thermal storage allows industries to benefit economically by reducing energy costs. By utilising prices from times of low or negative costs and shifting them throughout the day, OPEX for electrification sinks drastically. Read more on the savings of flexible electricity purchase with Kraftblock in our whitepaper. The thermal battery also allows for a secure and resilient energy supply. Additionally, Kraftblock costs less than other thermal energy storage systems and only a fraction of battery storage.
