For more than 15 years, Nuremberg Airport has been obtaining district heating from its direct neighbor, the Scherzer vegetable growing company. The heat is produced in a so-called wood chip heating plant. The heat is generated in the Scherzer heating plant using two large wood chip boilers and is piped to the airport as hot water via a pressure pipe. There, it is distributed in the buildings via the existing network to the radiators and ventilation systems. The heat from the wood chip plant is sufficient to heat the airport even on days with temperatures around freezing point. The gas heating only has to provide support during longer periods of frost. In order to merge the previously separate east and west heating networks in 2022, an approximately 500-meter-long, insulated connecting line was laid. This gave the large departure hall 2 and the DFS Tower, among other things, their own district heating connection, so that the entire airport site can now be supplied with district heating. "By connecting the two heating networks, Nuremberg Airport is taking another big step towards reducing CO2 emissions," said Airport Managing Director Dr. Michael Hupe. In addition, security of supply is increased, as two independent heating plants can now feed into the airport's heating network. Klaus Dotzauer, Managing Director of Nuremberg Airport Energy Company, adds: "Wood chips are largely climate-neutral and a raw material that does not depend on pipelines and is currently available in sufficient quantities. Last winter, we were able to almost do without the use of natural gas as an energy source." The Scherzer family business, which specializes in growing vegetables in greenhouses, has been using biomass since 2007: At that time, the wood chip heating plant went online within sight of the airport. In 2022, the plant was extensively modernized. The
