Ore Energy develops long-duration batteries built from iron, water and air that the company says can store electricity for up to 100 hours. Its chemistry is designed to be manufactured through a fully European supply chain and to avoid reliance on imported critical raw materials such as lithium or cobalt. The startup has signed a major long-duration energy storage system deal with Dutch energy supplier Budget Thuis and aims to commercialise its technology at scale. The company plans to use the proceeds of its recent funding to establish its first manufacturing facility. Financially, Ore Energy has raised a total of $61 million following the $43 million Series A. The company frames its product as addressing a key bottleneck for renewables and industrial growth by providing extended-duration storage capacity.
