MAN Truck & Bus SE has set itself an ambitious goal of reducing CO2 emissions by 50% by 2025 compared to 2015. The introduction of the energy management system in accordance with ISO 50001:2018 in all plants and the continuous further development of the CO2 roadmap are essential building blocks for the Group on the way to achieving this goal.
In order to replace the climate-damaging fuel lignite with CO2-free heat, the site managers decided to connect the plant to the local district heating network of N-Ergie. In addition to the conversion of the heat supply, several optimisation measures in the local heating network were also investigated in order to achieve the maximum CO2 savings.
In the project different approaches to waste heat utilisation were analysed technically and economically. Waste heat sources and sinks were compared and concepts were developed, for which the funding possibilities according to the “Bundesförderung für Energieberatung im Mittelstand” were researched.
eta Energieberatung also carried out the repeat audit for the SRH Group. During the audit, numerous individual measures were analysed and the potential savings identified. However, more urgent than the implementation of investment measures is the introduction of a comprehensive energy (data) management.
