The Energetic Modernisation of Neumayer Station III

Uwe Nixdorf, Peter Köhler, Thomas Matz, Christine Wesche Alfred Wegener Institute (AWI), Germany The AWI has erected and commissioned the first of the new wind turbines at Neumayer Station III, starting with the ship supply by the RV POLARSTERN in January 2023. The turbine, which rotates around its vertical axis and is operated several locations in Europe as a of the shelf product. It has been technically upgraded and tested in a climate chamber in advance and is now being tested under polar conditions. In order to be able to evaluate the stability of the lattice tower’s foundation in the snow with annual uplift, as well as the turbine's operational behaviour during strong storms prevailing at the station's coastal location, several monitoring systems were installed. Their data can be evaluated live in Europe. The station's power management system now controls and switches the electrical and, in part, thermal outputs of an HVAT, a VAWT (Vertical Axis Wind Turbine), a test solar plant and the CHP plant. The VAWT with a capacity of 50kW will feed directly into the station's network from March 2023 on and is designed to achieve annual fuel savings of about 10% in the prevailing wind field. After their successful testing, further VAWTs of the same type are to be installed, which will reduce the station's CO2 emissions as an essential element of an energetic modernisation concept. The NAP of Germany is investing considerable resources and funding in the conversion of the year-round Neumayer Station III for an even more energy-efficient operation. On the one hand, this is intended to expand the increased utilisation of the station over the years. This aims to reduce the CO2 footprint.
