Fuel cells will be part of the energy supply in the future, especially if they are operated with green hydrogen. However, in order to fully exploit their contribution to system security and grid-forming properties, unit and system certification is essential. This certification in accordance with FGW TR 8 ensures that every fuel cell meets the standards of VDE-AR 4105, 4110 and/or 4120 and is therefore a reliable component of a modern, sustainable energy system. In addition to storing energy in the form of hydrogen, the systems must be able to adapt dynamically to demand and at the same time support grid stability in normal and disrupted grid operation. This applies regardless of the size and design of the generation unit.

Your certification by M.O.E.

This means that the same requirements apply for fuel cells as for other decentralized generation systems, regardless of the operating mode. Fuel cells must also be electrically measured with regard to the grid connection when they feed into the grid. This is done as part of unit certification, which forms the basis for system certification. M.O.E. covers all certification and testing processes for this area via component certification (e.g. parking controllers) and model validation. Currently, system certification is carried out in accordance with VDE-AR-N 4110 “Technical rules for the connection and operation of customer systems on the medium-voltage grid (TAR Medium Voltage)” in conjunction with FGW TR 8. The unit certification requirement applies to all fuel cells regardless of size. System certification may be required from a size of 135 kW and a connection to the medium-voltage grid, i.e. from 1 kV to 60 kV.
