Implenia starts work on the tunnel in Hamburg
Construction of Hamburg's district heating tunnel has started. Implenia is building an almost 1.2-kilometre-long tunnel under the Elbe on behalf of the client, Wärme Hamburg. From the winter of 2024/25, it will transport industrial waste heat from the south to the north of the city.
Construction work on Hamburg's district heating tunnel began on August 5, Implenia announced in a statement . The construction and real estate company from Opfikon is realizing the project on behalf of Wärme Hamburg . The 1.16 kilometer long tunnel will cross the Elbe about 2 kilometers west of the Elbe tunnel for the autobahn.
From the winter of 2024/25, this will be used to transport waste heat from industrial processes in the south to the north of the Hanseatic city. This is a requirement so that the coal-fired power plant in Wedel can be replaced by energy from the future Hafen Energy Park of Hamburger Energiewerke GmbH . "We are pleased that we can plan and implement this large and complex infrastructure project for the Hamburger Energiewerke and thus contribute to a sustainable energy supply in Hamburg," said Thomas Fiest, Head of Tunneling Germany at Implenia.
In the first construction phase, Implenia is constructing the start and target shaft with diaphragm walls 1.5 meters thick and 30 meters deep. Then a tunnel boring machine will bore the actual tunnel with a diameter of 4.55 meters. Access and operating equipment for the operation should be accommodated in the shafts.
