OGE is a German gas grid operator and key player in the energy transition. With a pipeline network of around 12,000 km in length, OGE is one of Europe’s leading gas transmission system operators. OGE will perform long-term corrosion tests to assess the effect of critical impurities for safe design and operation of CO2 transport networks. They will also develop venting procedures for pipelines and perform experiments and assessment of underground leakage and dispersion.
