About this report
Stiesdal is a Danish technology group active in several climate-oriented industrial domains, including wind technology, hydrogen production systems, and long-duration thermal electricity storage.
Within this portfolio, the GridScale storage concept represents an approach to energy storage that differs structurally from electrochemical battery systems. The concept stores electrical energy as heat in crushed rock contained within insulated tanks and later reconverts that thermal energy into electricity when needed.
