Green hydrogen is a key part of Germany’s drive to decarbonize industry and transition to clean energy. To that end, the country is establishing a core network, spanning 10,000 kilometers all across Europe’s largest economy. What are challenges faced by the new distribution grid? How many of the old natural-gas pipelines can be repurposed? How much new construction is needed. Germany’s biggest gas network operator and the German Association for Gas and Water give us some answers.    Our Guests:   Philipp Ginsberg is Head of Grid and Heating Policy at the DVGW, the German Association for Gas and Water, which currently has around 14,000 members, including 2,000 utility companies.
