Dutch β¬30M Consortium for LDES
The Dutch SLDBatt project is bringing together a number of organizations to develop a new type of LDES to store renewable energy for 8 to 100 hours. Backed by over β¬30 million in funding from the Nationaal Groeifonds and the Rijksdienst voor Ondernemend Nederland (RvO), members of the seven-org group include two aqueous players:
- AQUABATTERY BV, which will develop a 50 kW saltwater acid-base power module prototype with 10 hours of storage duration.
- Elestor BV will install a 100 kWβ1 MWh hydrogenβiron flow battery pilot.
