Augwind Energy is developing an air battery system in Germany, targeting a commissioning timeframe of 2027-2028. Utilizing underground salt caverns, the system can store 3 to 8 gigawatt-hours of electricity, sufficient to support thousands of homes for several days.
The technology uses compressed air energy storage without reliance on lithium or rare minerals, presenting a significant cost advantage with estimated storage costs of $10 to $15 per kilowatt-hour. Germany's potential storage capacity is estimated at 330 terawatt-hours, significantly surpassing current European battery capacity.
This initiative may help mitigate Dunkelflaute, a challenge of low renewable energy generation. Success in this project could inform broader deployment across Europe by 2030.
