The energy supplied to EUREF-Campus is CO2-neutral. GASAG Solution Plus GmbH operates the EUREF Energiewerkstatt, which is the heart of the property in terms of energy. It generates 100 percent of the heating required on site.
The main element of the Energiewerkstatt is a combined heat and power plant. Biomethane combustion is used to power a generator to make electricity, which is fed directly into the Berlin power grid. The waste heat is used to heat water. At EUREF-Campus this is used to heat offices. The 90-degree water is pumped to the buildings through the underground district heating pipeline, which measures 2.5 kilometres.
Together with two smaller combined heat and power plants that produce electricity for operating the energy hub and zeeMobase, a large portion of the heating requirements at EUREF-Campus is covered. If additional heat energy is needed on very cold days, two low-temperature gas boilers are available for peak loads. In addition, the energy hub also provides cooling for the air-conditioning systems in the many service rooms and offices.
The energy hub is controlled by means of artificial intelligence, the so-called eco tool. Some 1,000 data points from the Energiewerkstatt and buildings transmit information on which energy is consumed in which buildings when. Weather forecasts and energy market data also factor into these calculations.
Power-to-heat / Power-to-cold technology makes it possible for the energy hub to store renewable energy. If too much energy is produced in solar parks or wind parks on sunny or windy days, this is registered in the energy hub. The excess electricity is then used to heat or cool water. The hot or cold water is stored in two well-insulated water tanks.
This storage system is part of the research project WindNODE, which is subsidized by the Federal Ministry for Economic Affairs and Energy.
In addition, Audi operates a 1.9 MWh second-use battery at the Campus. 20 discarded batteries from e-tron test vehicles are hooked up to form a large stationary battery and serve the Campus as a testing environment and grid stabilizer.
