Covestro Launches Heat Battery Project at Brunsbüttel Site

Key highlights
  • The Rondo Heat Battery at Brunsbüttel will operate by end of 2026.
  • It will save up to 13,000 tons of CO2 emissions annually.
  • The battery will produce 10% of the site's steam needs.
  • Breakthrough Energy Catalyst and EIB support the project.

Project Overview

Covestro and Rondo Energy have initiated the construction of a Rondo Heat Battery at Covestro's Brunsbüttel site. This innovative system will store surplus renewable energy in bricks, providing a sustainable alternative to fossil fuel-based steam generation for industrial processes.

Significance for Schleswig-Holstein

The project is a key step towards climate-neutral transformation in Schleswig-Holstein, as highlighted by Tobias Goldschmidt, the state's Minister for Energy Transition. It aligns with the region's goals of expanding renewable energy and achieving energy sovereignty.

Technical Details

The 100 MWh Rondo Heat Battery is expected to be operational by the end of 2026. It will supply 10% of the steam required at the site, potentially reducing CO2 emissions by up to 13,000 tons annually. The system uses bricks, a traditional heat storage material, to generate emission-free steam.

Support and Future Plans

The project receives backing from Breakthrough Energy Catalyst and the European Investment Bank. Covestro is assessing the potential for larger-scale deployment based on the Brunsbüttel site's experience.

Industry Implications

Eric Trusiewicz, CEO of Rondo Energy, emphasized the project's role in addressing Europe's energy challenges by providing reliable, affordable, and clean industrial heat. This initiative aims to enhance energy infrastructure and support the competitiveness of European industry.
