PILOT PROJECT: HIGH-TEMPERATURE STEEL STORAGE IN BERLIN

  • With Vattenfall Energy Solutions and Gewobag, a housing society, we are piloting a steel-based district storage system in the disused heating station of a large apartment block in Berlin. The sector-coupling steel storage system will absorb regional generation peaks from wind and solar energy and later provide renewable energy as heat and electricity. This project aims to show how well our steel-storage technology is suited to effectively store large amounts of wind and solar energy.
  • With this pilot project we want to demonstrate in a very practical way the special technical and economic suitability of thermal storage systems for the effective use of large amounts of wind and solar energy.
  • Storage capacity: 2,4 MWh
  • Implementation period: April 2018 to October 2020

This project is co-financed by the European Regional Development Fund [ERDF].

DEMONSTRATOR AT THE HTW GRID SIMULATION LABORATORY

  • Since 2018 we have been testing our high-temperature steel storage systems under real conditions in the grid simulation laboratory of the University of Applied Sciences (HTW). In particular, we are testing the fast charging of the steel storage with high power current – as it would occur at times of high solar and wind power peaks.
  • Storage capacity: 450 kWh
  • Implementation period: April 2018 to October 2020

This project is co-financed by the European Regional Development Fund [ERDF].
