A Norwegian startup has secured USD 17.5 million (EUR 15 million) in a Series A funding to develop a new seasonal energy storage system aimed to help homes store excess amounts of solar energy in summer for use during the winter.

Designed by Oslo-based energy storage scaleup Photoncycle, the seasonal solid-state hydrogen energy storage system is set to roll out commercially in Denmark and the Netherlands. It aims to tackle long-duration storage across seasons, one of the greatest challenges facing renewable energy systems.

Likely a metal hydride based system. It is at present the only geniuinely mature way of storing hydrogen in a solid state form.
