PILOT PROJECT: HIGH-TEMPERATURE STEEL STORAGE IN BERLIN

  • As part of our pilot project in boiler house II on Bottroper Weg, we have built a high-temperature steel storage tank in Berlin-Tegel to test the commercial use of the technology and transfer it to regular operation. The storage tank was integrated with the existing heat supply system of Vattenfall Energy Solutions into the district power and local heating supply of the surrounding 1970s multi-storey apartments of Gewobag. By using our storage tank, the CO2 balance of 362 apartments on Bottroper Weg will be further improved.
  • 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
