Brenmiller Energy Joins Forces with Baran to Scale Thermal Energy Storage Solutions Globally

The thermal energy storage sector is witnessing a major shift as Brenmiller Energy and Baran Energy announced a landmark partnership aimed at accelerating the commercial deployment of cutting-edge heat battery technology worldwide. This collaboration brings together Brenmiller’s pioneering bGen™ ZERO thermal storage systems with Baran’s extensive infrastructure development expertise and financial capabilities.

What This Partnership Means for Industrial Heat Solutions

Under the framework agreement, Baran Energy—the project development arm of the Baran Group, Israel’s most established engineering conglomerate—will acquire selected thermal energy storage projects from Brenmiller’s existing portfolio. The two companies will jointly pursue new opportunities across both Israeli and international markets, with the primary goal of generating sustainable, recurring revenue streams while simultaneously reducing industrial greenhouse gas emissions.

This strategic alignment represents more than just a commercial transaction. It reflects the growing recognition within the energy sector that thermal storage technology is essential for supporting renewable energy adoption and decarbonizing industrial processes. Baran’s four decades of infrastructure project execution experience, combined with Brenmiller Energy’s innovative heat battery platform, creates a powerful foundation for scaling clean energy solutions.

The Scale of Opportunity

Brenmiller Energy’s current project pipeline tells an impressive story. With over $440 million in commercial opportunities already identified, the company has positioned 103 MWh of bGen™ thermal storage capacity across multiple projects in various stages of operation and construction worldwide. This pipeline represents substantial momentum in a market that’s increasingly demanding alternatives to fossil fuel heating systems.

Avi Brenmiller, the company’s founder and CEO, emphasized that the partnership enables faster market response. “Growing demand from Fortune 500 companies and other global leaders means we need reliable execution partners,” he noted, highlighting how Baran’s project management capabilities address a critical bottleneck in deployment speed.

Understanding bGen™ Technology

The bGen™ system works by converting low-cost renewable electricity into stored thermal energy within crushed rock formations. When industrial customers need heat—for steam generation, hot water, or process air—the system discharges on demand. This approach provides industries with a zero-emission alternative to traditional natural gas boilers while maintaining cost competitiveness.

The technology gained significant validation in 2023 when TIME magazine named bGen™ among its Best Inventions in the Green Energy category. Beyond industrial applications, the system also contributes to grid stability by providing flexibility and load-balancing capabilities for renewable energy infrastructure.

Long-Term Growth Trajectory

Izek Frank, CEO of Baran, positioned the partnership within the company’s broader energy sector strategy. “Targeted project investments in thermal storage create dual value: meaningful cost reductions and emissions decreases for industry, alongside long-term shareholder returns,” he stated. Baran’s first two thermal energy storage projects with Brenmiller Energy mark the beginning of what both partners expect to be a progressively larger collaboration.

The cooperation framework allows Brenmiller Energy to maintain its focus on technology development and customer relationships while Baran handles project execution, financing structuring, and local market navigation—a division of labor designed to accelerate deployment while controlling costs and managing technical risks effectively.
