Provides bGen thermal batteries that turn electricity or residual heat into industrial heat, steam, or power. Revenue can come from system sales, engineering and maintenance, or long-term Energy-as-a-Service arrangements, with a planned shift toward owning and operating integrated energy assets.
Designs and deploys bGen thermal energy storage systems, which use crushed rock to convert electricity or residual heat into industrial steam, hot air, hot water, heat, or power. Modular bCube units are manufactured in Israel and assembled on site; a gated product-development process runs from feasibility and basic design through alpha and beta sites to a detailed product file. Target markets include the United States, Europe, and Israel.
Generates revenue through equipment sales and integration, engineering and maintenance, and Energy-as-a-Service agreements to supply heat or steam. Plans under the BrenX brand also encompass solar generation, battery storage, energy management, and ownership of integrated energy assets. Project financing, construction and performance, local energy and boiler approvals, third-party suppliers and contractors, and the bGen platform are central dependencies.
