Epyr raises €15 million Series A for industrial heat storage

SlateVC leads funding to deploy further European projects.

Epyr announced an oversubscribed €15 million Series A on October 13, led by SlateVC. AENU, Daphni, WEPA Ventures, OVNI Capital and Aurum Impact also participated.

The capital supports new industrial heat storage projects, including a planned 35 MWh installation for French papermaker Papeco. It follows a unit commissioned at WEPA’s Troyes mill in May.

Epyr stores electricity as high-temperature heat, allowing factories to buy power when prices are lower and use the energy when their processes need it.
