In Grevesmühlen, the two energy specialists Fenecon and The Mobility House Energy are building a high-performance large-scale storage facility with a capacity of 48 MWh, similar to a sister project with 8 MWh in North Rhine-Westphalia.
Once the local substation in the German state of Mecklenburg-Western Pomerania has been completed by the local energy company E.DIS Netz GmbH, the storage facility is planned to start operating in the second half of 2025. The special feature of the stationary battery system is that only new, but obsolete traction batteries from electric vehicles will be used. Preparation for the construction are nearly complete, according to the initiators.
The not-used batteries will be taken from a variety of different manufacturers and standardised in stationary large-scale storage systems, which The Mobility House then plans to bring to market “based on its many years of expertise and intelligent marketing algorithms that minimise battery ageing and maximise economic efficiency.”
This is not the first such cooperation between Fenecon and The Mobility House, who have a container-based stationary battery storage concept operating in both Iggensbach, Germany, and Greenville, USA. These are also using multiple sources of batteries, which the operators advertise as follows: “Many of these very high-quality and long-lasting battery packs, which are not installed in the vehicle due to model changes, surplus production or missed car sales plans, are thus used sustainably in the sense of a circular economy.”
“In Germany, more brand-new and high-quality electric vehicle batteries, which have unfortunately become obsolete, are currently thrown into the shredder every year than batteries are installed as part of large-scale storage systems – which in turn are usually newly produced here from China,” explained Franz-Josef Feilmeier, CEO of Fenecon, adding: “Our mission and that of our committed partners and customers is to utilise these high-quality batteries in the energy market as part of Made-in-Germany stationary storage systems, taking advantage of the properties of these batteries in terms of round-trip efficiency or thermal management and thus lower operating costs.”
In Germany, The Mobility House has also established a joint venture together with Green Energy Storage Initiative to build and market large-scale battery storage systems, planning to operate in capacities of 250 MW and later expand to 500 MW.
