Rock Energy Storage is a privately held company based in New York. It is focused exclusively on taking advantage of the sizable TES storage opportunity in the United States by distributing, installing, and servicing Brenmiller’s bGen™ TES solutions throughout the Northeast. RSP Systems will act as Rock Energy Storage’s lead subcontractor. Brenmiller had previously announced on January 11, 2024 that it had signed a Memorandum of Understanding with RSP Systems; the current agreement with RES supersedes the previous agreement and is a natural evolution of the companies’ successful collaboration.

“The Northeast is a strategic U.S. market for Brenmiller because of its forward-looking approach to electrification and decarbonization and is well-suited to take advantage of the sustainability and flexibility benefits that our cost-effective bGen™ technology unlocks,” stated Brenmiller’s Chairman and CEO, Avi Brenmiller. “We have enjoyed a very productive working relationship with RSP Systems since 2019 and are excited to grow our collaboration with the team through Rock Energy Storage.”

RSP Systems, a leader in choosing and implementing award-winning energy generation systems since 2004, worked with Brenmiller on its first U.S. bGen™ installation in New York.

“Brenmiller’s TES system is the competitive decarbonization solution we’ve been looking for, and we have already seen excellent reception from a range of market sectors and organizations that are forward-leaning in their efforts to decarbonize, including utilities, commercial and industrial, institutional, and food and beverage,” said Cory Glick, President and CEO of Rock Energy Storage. “Brenmiller’s technology qualifies for substantial federal incentives through the Inflation Reduction Act, and state and utility programs will provide additional tailwinds for our work to introduce the bGen™ to more states in the U.S. We look forward to partnering with Brenmiller to meet our energy customers’ rapidly changing and growing demands for clean power.”

As of May 1, 2024, Brenmiller and RES have numerous active project proposals in their shared pipeline, representing over 1,200 MWh of TES capacity.

Brenmiller’s bGen™ TES technology replaces the need for fossil fuel boilers at industrial and power plants, which contribute to nearly one-quarter of all global emissions. It uses crushed rocks to store low-cost electricity from renewable or other sustainable sources and dispatches steam, hot water, or hot air according to customers’ needs. Brenmiller’s TES technology is modular and highly configurable and provides heavy-emitting and mission-critical customers with scalable access to zero-emission heat while ensuring 24/7 operational reliability.

About bGen™

bGen™, Brenmiller’s TES system, converts electricity into heat to power sustainable industrial processes at a price that is competitive with natural gas. The bGen™ charges by capturing low-cost electricity from renewables or the grid and stores it in crushed rocks. It then discharges steam, hot water, or hot air on demand according to customer requirements. The bGen™ also supports the development of utility-scale renewables by providing critical flexibility and grid-balancing capabilities. bGen™ was named among TIME’s Best Inventions of 2023 in the Green Energy category.
