Ore Energy signs 1GWh iron-air battery supply agreement with Budget Thuis for multi-day energy storage deployment in the Netherlands

Type: Supply Agreement · Technology: Storage · Country: Netherlands · Capacity: 1 GWh · Announced: 2026-06-22

Ore Energy, a Dutch multi-day energy storage startup headquartered in Amsterdam, signed a supply agreement with Budget Thuis, a Dutch energy and telecoms utility supplier, to deploy up to 1,000MWh of iron-air battery energy storage systems. The first phase commits Budget Thuis to 400MWh of capacity, scheduled for delivery in 2028, marking a material commercial deployment for Ore Energy's non-lithium, cobalt-free technology. Ore Energy's iron-air batteries use iron, water, and air chemistry, configured for discharge durations of 24 to 100 hours, packaged in 40-foot enclosures suitable for utility-scale applications. The technology is positioned as a solution to store excess wind energy in the Netherlands, addressing curtailment challenges and reducing reliance on fossil fuel generation during periods of low renewable output. Budget Thuis CEO Annemarie Buitelaar emphasized the iron-air technology's suitability for long-duration storage, enabling the utility to store clean electricity when abundant and deliver it during peak demand periods. Ore Energy CEO Aytaç Yilmaz highlighted the technology's European supply chain advantages and its potential to become as critical for wind energy as lithium-ion has been for solar PV.
