Article and interview in Solar365 magazine: Elestor to build largest hydrogen battery ever
For the energy transition to succeed, sufficient renewable generation is required, but also the ability to store that energy for longer periods. Technologies capable of storing energy between eight and one hundred hours can play a crucial role. A broad consortium has received €22 million in funding from the Dutch National Growth Fund for the so-called SLDBatt project (Sustainable Long Duration Battery), which focuses on long-duration electricity storage.
