Brenmiller: new flexible and sustainable tech for energy storage

Published on Monday, 11 November 2019

“Innovation for me is a state of mind. I believe that innovative people are driven by the desire to set a goal and achieve it”

– Avi Brenmiller, Chairman & CEO of Brenmiller

Storing high temperature energy

Lower costs, total flexibility, multiple energy sources, environmentally friendly and able to resist temperatures of up to 750º. This is the bGen™super system, which Brenmiller has developed.  “The main patented technology is for a high temperature energy storage based on crushed rocks. This combines three elements: a heat exchanger, thermal storage and a steam generator. The unit has low costs, minimal maintenance and no augmentation for 30 years, therefore driving the record low prices,” Brenmiller adds.

It is considered a ‘green engineering’ unit, as he explains: “No hazardous substances and no chemicals are used in the storage media. Accordingly, there are zero emissions  when using the bGen™. It also lowers the CO2 emissions by reducing fuel consumption”. The unit can receive heat or electricity from various sources in order to charge the storage unit, and can produce steam in various conditions using its inherent steam generator for multiple hours while maintaining a steady output in terms of temperature and pressure.

This technology can be used for a broad range of applications and markets. Specifically, “in the thermal world the bGen™ could be used in large and small thermal power plants to increase their flexibility and efficiency, recover waste heat, decouple electrical and thermal supply and electrify heat” Brenmiller explains.  Their target clients would be utilities, developers and Consumer and Industrial clients.

A genuine, shared belief in innovation

“Together with Enel’s Global Power Generation Innovation team, we have worked very closely for the last two years to explore the benefits that the technology can bring to the market”. Together, we have conducted a feasibility study where we analysed all technical and economic elements of Brenmiller’s technology. “The close work with and continuous feedback from Enel, and their 360º view of the market, have brought us to perfect our offering to the market and increase our value proposition” Brenmiller says. “This close perspective enables Enel to point us in the right direction”.

Brenmiller adds that the personal approach and the open mind towards innovation is something “very unique we see in our joint work with Enel”. He believes that “Many large organisations speak about the need for innovation. But when it comes to investing time and resources, they usually don’t take many risks. Enel is different, they continuously look around for innovative technologies and support best products up to the scale up on the market”.

What’s next? Brenmiller’s future plans include expansion in several markets and scaling up their production capabilities. For this reason their collaboration with us is highly relevant: “Enel play several roles that will support our growth, starting from market validation, and moving to installation in Enel’s power plants, both Thermal and Renewable”.
