Spanish renewable energy giant and offshore wind energy leader Siemens Gamesa Renewable Energy last week inaugurated operations of its electrothermal energy storage system which can store up to 130 megawatt-hours of electricity for a week in volcanic rock.
Siemens Gamesa, a company known more famously for its offshore wind turbines, is nevertheless a large-scale renewable energy technology manufacturer, with its hands in various renewable technology pots. One of these pots is energy storage, and last week the company announced the beginning of operations of its electric thermal energy storage system (ETES), claimed by the company as a world first. The opening ceremony for the pilot plant in Hamburg-Altenwerder was held last week to celebrate the beginning of operations.
The newly-opened electric thermal energy storage system is billed by Siemens Gamesa as “The Future Energy Solution” and as costing “significantly” less than classic energy storage solutions. Specifically, according to the company, even at the gigawatt-hour (GWh) pilot scale, ETES “would be highly competitive compared to other available storage technologies.”
