Aytaç Yilmaz, Ore Energy CEO, said that with renewable energy already being curtailed at times of overabundance in Europe, “wasting electricity that costs billions to generate,” grids are currently dependent on fossil fuels to fill the gaps.

“Short-duration batteries alone can’t fix this. They shift solar by a few hours, but wind-heavy European grids need storage that works across days, not hours,” Yilmaz said.

Similarly, Budget Thuis CEO Annemarie Buitelaar said that the iron-air technology will enable the utility to “store clean electricity when it is abundant and deliver it when it is most valuable.”

The Ore Energy technology is “especially compelling because it is designed for the long-duration use cases that conventional batteries are not built to cover, with a cost structure suited to multi-day storage,” Buitelaar said.

“For us, this is about reducing exposure to volatile fossil fuel prices while giving customers access to cleaner and more predictable electricity over time. Ore Energy has demonstrated the technology and has the expertise to deploy it, which is why we are committing to 1GWh across our portfolio, starting with a 400MWh first phase.”
