Published: · Updated:
Epyr announced a €15 million Series A round on October 13 led by SlateVC. The company develops systems that use electric resistors to store heat in bricks when power is inexpensive, then supply that heat when industrial processes need it.
Epyr’s first industrial unit, at the WEPA paper mill in Troyes, entered service in May 2026 and now covers up to one quarter of the site’s steam needs. The company says it has been selected for a new 35 MWh unit at Papeco; that project has been announced but is not yet operating.
