Energy Storage: 13 MWh second-use battery for grid stabilization in Lünen
The world's largest second-use battery storage is starting up. The 13 MWh project is now nearing completion after a construction time of just under one year: a total of 1000 battery systems from second-generation smart fortwo electric drive cars are being grouped into a battery storage in Lünen, Westphalia. The first power units are already in the grid.
Full capacitity before the end of the year
The 13 MWh battery storage will put its full capacity at the disposal of the German energy market before the end of this year. The output will be available to the winner of the weekly auctions among the network operators for primary controlling power range, with fully automatic energy storage and feed-in.
Efficient management of energy and material resources
Efficient management of energy and material resources also applies to all components used in electromobility. The joint venture between partners Daimler AG, The Mobility House AG and GETEC has a future-oriented answer to the key question of reusing electric vehicle battery systems with this second-use battery storage. Because the lifecycle of a plug-in or electric vehicle battery does not end after the vehicle's operating life.
Ten years longer cost-effective use
If used in stationary power storage, the systems are fully operational even after the service life guaranteed by the manufacturer – with slight capacity losses only of secondary importance. Cost-effective use in stationary operation is possible for at least an estimated ten years longer. Reusing the modules from electric cars in a battery storage doubles their economic value and also demonstrably improves their eco-balance.
With the project in Lünen, the four partner companies cover the entire battery added value and second-use chain. This includes the recycling of these battery systems at the end of their lifecycle and the return of the valuable raw materials to the production cycle, which will be the remit of REMONDIS. (HCN)
