Physical integration of the electrolyser and customer site acceptance test

The HPEM2GAS project aims to demonstrate an innovative PEM electrolyser at the Emden Council in Germany to assess the stack’s and system’s robustness to cope with dynamic situations under real-life operating conditions in a field test campaign. The produced hydrogen is fed into the local natural gas grid. For the start of the field testing activity site preparation and connections between the electrolyser and the electricity and gas grids had to be made in Emden. Before the electrolyzer was delivered to Emden, Germany, all necessary measures were taken in this regard and discussed in this deliverable.

For the integration of the electrolyser, a control station was positioned before feeding the hydrogen it into the natural gas network. This runs through the control station to the mixer in the gas transfer station. Several safety-relevant elements are installed along the route. All installed elements were approved by a German Association of Gas and Water (DVGW) expert. Before the start of the field test, an inspection by a TÜV inspector also had to be carried out. Only after the approval by these two organisations is was legally permitted to put the electrolyzer into operation.
