Stock Photo - 02 November 2023, Hamburg: Pastor Sieghard Wilm of St. Pauli Church holds the statue of St. Barbara, patron saint of miners, next to godmother Katharina Fegebank (Bündnis 90/Die Grünen), Second Mayor and Senator for Science, Research and Equality, before the start of drilling for Hamburg's new district heating tunnel under the Elbe. In accordance with mining custom, the tunnel boring machine for the new district heating tunnel under the Elbe was christened ""Hermine"" in Hamburg-Waltershof. The Elbe tunnel, which is just under 1.2 kilometers long and can be walked through, will connect the Hafen energy park with its combined-cycle gas turbine power plant, which is still under construction, and the industrial waste heat from the port operations with the district heating network on the north bank of the Elbe. By the end of 2025, the aging coal-fired power plant in Wedel will be replaced. Photo: Marcus Brandt/dpa. - Hamburg/Hamburg/Germany
