BOS-Brandenburg: 115 fuel cell systems

In grid section 43 of the state of Brandenburg, 115 base stations were equipped with fuel cells as grid replacement systems (W-NEA). The implementation was carried out within a funding project from the National Hydrogen and Fuel Cell Technology Innovation Programme (NIP) of the then Federal Ministry of Transport, Building and Urban Affairs (BMVBS) under the technical supervision of the National Organisation Hydrogen and Fuel Cell Technology (NOW GmbH). Special attention was paid to the testing of fuel cells as grid replacement systems within a critical infrastructure. It was therefore a logical step to test the reliability of the fuel cell systems in operational use. This task was carried out over two warm/cold periods within the framework of scientific monitoring by the Technical University of Wildau. At each location, fuel for at least 72 h emergency power supply. In total, 450 kW of fuel cell power was installed in NA43 and tested in 4620 provoked power outages, during radio operation. The basis for this was a comprehensive online monitoring system, which enables the control and monitoring of the systems in real time and guarantees the required availability. The retrospective cooperation with all project partners and contractors was and is on a technically high level and has taken the state of Brandenburg a big step towards the required reliability in the context of network hardening.
