Brenmiller's second generation thermal energy storage system, the bGen ZERO

Brenmiller's second generation thermal energy storage system, the bGen ZERO

The bGen ZERO offers a modular, flexible design with fast charge and discharge times, all without the use of hazardous materials. Additional highlights and improvements from prior bGen™ systems include:

  1. Improved Efficiency: 33% reduction in heat loss, 99% charging efficiency, 97% cycle efficiency (power to heat), and 98% year-round availability.
  2. Boosted Energy Density: 34% improvement in energy density and 40% improvement in discharge power.
  3. Swift Response and Continuous Operation: Engineered for fast one second response rate and uninterrupted operation at maximum capacity, tailored for high demands of the power grid for reserve power and stability.
  4. Compact and Modular: Fully modular, productized solution that ensures the highest quality standards, rapid on-site installation, and commissioning. Occupies minimal space due to its unlimited storage height.
  5. Impressive Steam Power Generation: Delivers substantial steam power generation, offering a stable steam supply for various power, commercial and industrial applications.
  6. Smart and Safe Operations: Features an intelligent module operation package with predictive maintenance and optimized performance based on market prices one day ahead, coupled with storage performance insights. Remote control operation via the Brenmiller control center. Robust cyber protection measures to ensure security and reliability.

The unveiling of this new product underscores a strategic evolution in the Company’s focus on power-to-heat for the industrial market. The bGen ZERO design, paired with performance improvements, presents a multi-use solution to tap into decarbonization which Brenmiller believes will unlock new revenue streams across applications including grid services. Brenmiller has also identified to avenues in which to offer their product in order to expand access to its TES solution:

  1. Direct Equipment Sale: Brenmiller continues to offer its second-generation TES solution for direct purchase by and integration with industrial facilities and power plants. The Company generates recurring revenues by providing after sales services such as warranty, maintenance, and optimization.
  2. Energy as a Service: Brenmiller generates recurring revenue streams by partnering with clean energy utilities for grid services. Brenmiller provides the bGen ZERO technology and integration while the partner provides clean electricity and financial support. Engaging in grid services unlocks a new, significant revenue stream for Brenmiller, while the end customer benefits from no capital expenditures, reduced operation risk, and emissions reductions. The bGen ZERO helps boost flexibility and stability for power grids by using excess renewable energy to generate heat.

“We named our next-generation system ZERO, because it charges from clean power sources such as solar and wind, produces clean heat, eliminates carbon in the production process, reduces costs, and importantly, bGen ZERO itself is built from environmentally friendly, nonhazardous materials,” said Avi Brenmiller, President and CEO of Brenmiller. “Our new high-performance design is the culmination of years of pilots and installations with customers across a variety of applications. Based on our market experience, we believe that the greatest impact our technology can deliver for the environment and for our customers is in the electrification of heat to provide 100% clean energy to industry, replacing the outdated polluting boilers of yesterday.”

Brenmiller has signed several memorandums of understanding and is currently in talks with major industrial and clean energy companies for more collaborative agreements. The Company’s commercial pipeline includes systems which could be deployed in multiple industries including food and beverage, hospitals, chemicals and green hydrogen.

The Company will host a live webinar today, August 9, at 11 AM EDT, followed by Q&A. Register here. The webinar will be held in Hebrew on Thursday, August 10, at 10:30 AM IDT. Register here. The webinars will also be made available on-demand on the Company’s website.

About Brenmiller Energy Ltd.

Brenmiller Energy delivers scalable thermal energy storage solutions and services that allow customers to cost-effectively decarbonize their operations. Its patented bGen thermal storage technology enables the use of renewable energy resources, as well as waste heat, to heat crushed rocks to very high temperatures. They can then store this heat for minutes, hours, or even days before using it for industrial and power generation processes. With bGen, organizations have a way to use electricity, biomass and waste heat to generate the clean steam, hot water and hot air they need to mold plastic, process food and beverages, produce paper, manufacture chemicals and pharmaceuticals or drive steam turbines without burning fossil fuels.
