Fuel cell instead of lead-acid battery

Stromnetz Hamburg inaugurates eco-friendly alternative at its main distribution site at Lokstedt . Fuel cell secures energy supply in case of cuts

With the inauguration of a fuel cell in Stromnetz Hamburg’s main distribution on 2 December, an innovative emergency power concept has seen its Northern German premiere. The Heliocentris fuel cell will ensure the operation of the mai distribution work during a power failure.

Safeguarding the Energy Supply During Power Cuts

Each power distribution plant requires a network-independent auxiliary power supply in order to provide energy for for at least eight hours during large-scale power outages. With the implementation of a fuel cell, a major step towards eco-friendliness has been taken. The goal of environmentally sound construction of distribution plants is almost fully achieved. In addition to reducing the use of lead, the hydrogen needed for the operation of the fuel cell will be produced by renewables. Even though smaller in size, the fuel cell solution significantly extends the time a power cut can be covered, as hydrogen can be easily reloaded.

Low-Maintenance and Eco-Friendly Technology

By using the energy carrier hydrogen, lead and other heavy metals will no longer be needed. The fuel cell operates as an electrochemical converter, in which hydrogen and oxygen are being connected in a controlled electrochemical process. From this connection, electricity and heat can be recovered.

Michael Pollmann, State Council of Environment and Energy of the Free and Hanseatic City of Hamburg: “The project of Stromnetz Hamburg vividly demonstrates the advantages of this technology: it is low-maintenance and environmentally conscious. Fuel cells are the future.”

Dr. Dietrich Graf, technical director of Stromnetz Hamburg GmbH: “By using this technology, we are securing that our plant will be efficiently supplied with emergency power. Our fuel cell stands for a modern and environmentally friendly system concept. “
