Covestro to deploy innovative heat battery from Rondo Energy

The battery will generate 10% of the steam needed at the Covestro site in Brunsbüttel with renewable energy

Covestro is partnering with Rondo Energy to install an innovative heat battery for the first time. The Rondo Heat Battery stores intermittent renewable electricity and delivers continuous high-temperature steam, thus offers a sustainable alternative to steam generation with fossil fuels.

The Breakthrough Energy Catalyst foundation set up by Bill Gates and the European Investment Bank (EIB) are supporting this installation of the Rondo RHB100 heat battery, which is scheduled to begin operation at Covestro’s Brunsbüttel site at the end of 2026. The project will then produce ten percent of the steam required at the site, saving up to 13,000 tons of CO 2 emissions per year.

"As an innovation company, we are always excited when we can further develop and test promising ideas that can bring us closer to our goals of a circular economy and climate-neutral production,” says Dr. Thorsten Dreier, CTO of Covestro. “The heat battery is such an idea: a new technology that allows us to go one step further on our way to a sustainable future.”

"Rondo Heat Batteries deliver deep decarbonization by changing the fuel, not the factory,” said Eric Trusiewicz, CEO of Rondo Energy. “We’re honored to be working with Covestro to prove our safety, reliability, and efficiency under real conditions on large scale over a long period of time. And we’re excited to be deploying in Brunsbüttel, where large flexible electricity loads are particularly valuable to the electricity grid.”
