Epyr raises €15M for industrial heat storage tech
French industrial energy startup Epyr has raised a €15 million Series A round led by SlateVC. Existing investors also participated.
The funding follows the company’s first commercial deployment of its high-temperature heat storage system at an industrial site. The technology captures excess renewable energy as heat in ceramic bricks, then releases it on demand to replace fossil-fuel boilers in processes such as cement and steel production.
While thermal storage is not new, Epyr’s modular, containerised approach targets mid-sized factories that may lack the space or capital for larger-scale solutions. The Series A will fund further deployments in markets where industrial heat accounts for a significant share of energy demand.
The round arrives as manufacturers face tightening carbon regulations and volatile energy prices. Unlike battery storage, which competes with grid-scale projects, thermal storage is rarely discussed in venture circles—yet it directly addresses the hardest-to-abate sectors. Epyr’s raise suggests investors are warming to the segment after years of pilot projects.
