Israel Hospital Cuts 3,900 Tons of Emissions Annually

Wolfson Medical Center in Holon, Israel, just started construction on a thermal energy storage system that will replace its fossil fuel boilers with clean electricity.

The $4 million project will cut the hospital's carbon emissions by 3,900 tons annually. That's equal to taking 1,000 cars off the road every single year.

Brenmiller Energy and Baran Energy are installing a 12 megawatt-hour system that charges from the electric grid during off-peak hours. The stored energy then delivers steam around the clock for sterilization, heating, and other critical hospital operations.

The technology works like a giant battery for heat instead of electricity. It converts cheap overnight power into thermal energy that the hospital can use whenever needed.

Construction should wrap up by the end of 2026, with the system going live in early 2027. Israel's Ministry of Health, Ministry of Energy, and Ministry of Finance all endorsed the project.

The Ripple Effect

This project shows healthcare facilities worldwide a blueprint for cutting costs and emissions simultaneously. The $1.5 million in annual energy savings can fund better patient care, new equipment, or additional staff.

Gadi Davidovich, Wolfson's Chief Engineer, says the system is expected to significantly reduce and potentially eliminate fuel consumption at the hospital over time. That means cleaner air for patients, staff, and the surrounding community.

The Energy-as-a-Service model used here makes the transition even easier. The hospital doesn't need to pay the full $4 million upfront. Instead, it pays over time through the energy savings the system generates.

Hospitals operate 24/7 and use enormous amounts of energy for heating, sterilization, and climate control. If other medical centers follow Wolfson's lead, the healthcare sector could become a major driver of emissions reduction.

CEO Avi Brenmiller says the project demonstrates that thermal energy storage can operate at meaningful scale while delivering measurable value. The technology is ready now, not years away.

Healthcare facilities around the world spend billions on energy every year while contributing significantly to carbon emissions. Wolfson is proving they don't have to choose between quality care and environmental responsibility.
