Ore Energy builds iron-air batteries for long-duration energy storage.
$43MSeries A
Iron-air batteries are finally getting real capital—this $43M Series A signals that long-duration storage (8+ hour discharge) is moving from R&D theater to commercialization. Ore's likely burning this on scaling manufacturing and proving cycle life at grid scale, which means the category is past the "does it work in a lab" phase. If you're building anything that needs predictable, cheap energy availability (industrial heat, hydrogen production, data centers), watch whether Ore hits their cost targets—that's the real gate for whether this tech actually displaces lithium for stationary storage.
