Large scale power storage
Store excess renewable energy for later use with our mineral thermal storage systems.
Seasonal storage
Our mineral thermal energy storage enables seasonal energy storage. Saving solar energy during the summer months for use in winter. Overcome the intermittency of solar power and provide a reliable source of renewable energy throughout the year. This ensures a consistent supply of clean energy, reducing reliance on fossil fuels.
100%
100% full power all the time. Run your power plant at full capacity. Charge the Grensle storage during surplus hours.
180 days
180 days storage cycle in Grensle large-scale mineral storages. Save energy from summer to winter.
1% cost
Store energy at only 1% of storage cost compared to the cheapest electric battery stations.
Hot mineral thermal storage
Save surplus electric energy in Grensle hot mineral storages. Built on site with local natural minerals and materials.
