Thermal Energy Storage project at Hospital will reduce GHG emissions by 95% and thermal energy costs by 40%

Thermal Energy Storage (aka- "Thermal Batteries) continues to advance as cost-effective solution for decarbonizing thermal energy loads traditionally dependent on fossil fuels. A key differentiator of Thermal Energy Storage (TES) is the ability to use off-peak power, when rates are lowest, and efficiently convert & store this power into useful thermal energy. This stored thermal energy can then be used, as needed, to provide either steam or hot water loads. The Wolfson Hospital is a 635 bed, multi-disciplinary medical facility. The hospital's management wanted to reduce their GHG emissions, in addition to reducing their annual energy costs. After reviewing numerous options, the hospital selected the Brenmiller patented bGEN technology to replace their aging boiler system. The final system sizing and design specified a 15 MW-hour bGEN system which now provides steam to the facility for building heat, domestic hot water, and HVAC systems. The bGEN system will reduce Carbon emissions by 3,900 tons per year, and overall GHG reduction of 95%. Since the bGEN system is charged during off-peak hours, when prices are lowest, this reduced their annual energy cost of steam production by 35%. The Wolfson Hospital finalized their agreement to procure a bGen(TM) ZERO system from Brenmiller via an energy-as-a-service (EaaS) model. bGen ZERO will replace Wolfson Hospital's old diesel boilers that are both costly and polluting. The electric heat provided via Brenmiller's bGen(TM) ZERO TES system will save Wolfson Hospital up to $1.3 million annually and reduce the hospital's local carbon footprint by 3,900 tons per year (a reduction of 95% related to building heat). "The project is expected to drive reduction in our fuel oil consumption to nearly zero," said Gadi Davidovitz, Chief Engineer at Wolfson Hospital. "It will significantly reduce emissions generated by the hospital while saving on energy costs."
