Mobile energy storage equipment in Hamburg Germany

Mobile energy storage provides a clean alternative to diesel generators for locations with no grid connection or only a weak one. Grid congestion creates increasingly long waiting times for companies who want to increase their grid connection. Mobile energy storage is the temporary solution to keep your business running.

The 130MWh Electric Thermal Energy Storage (ETES) demonstration project, commissioned in Hamburg-Altenwerder, Germany, in June 2019, is the precursor of future energy storage solutions with gigawatt-scale charging and discharging capacities. Siemens Gamesa, Hamburg University of Technology, and Hamburg Energie.

This leads to considerable energy losses, which drive up the price of electricity. To counter this, Germany needs enormous storage capacities. We already have more than 100 gigawatts of excess solar and wind capacity in the 4 to 5 hours of midday, which is lost without storage.

Alfen's mobile energy storage products are sustainably produced, fully recyclable, and ensure zero emissions on-site. Mobile energy storage provides a reliable power solution that is easy to operate and robust enough to withstand harsh conditions. Perfect for temporary energy needs.

The Electric Thermal Energy Storage system can store up to 130MWh of thermal energy for a week, which can be converted back into electrical energy using a 1.4MW steam turbine generator that can produce electricity for up to 24 hours.

The Hamburg ETES demonstration facility is designed to draw surplus electricity from the grid, store it in the form of thermal energy, and utilise the same to produce electricity, when it is most needed. The facility is capable of powering 1,500 German households a day.
