On behalf of the Port of Rotterdam Authority, the Wuppertal Institute developed three possible pathways for a decarbonised port of Rotterdam until 2050. The port area is home to about 80 per cent of the Netherlands' petrochemical industry and significant power plant capacities. Consequently, the port of Rotterdam has the potential of being an international leader for the global energy transition, playing an important role when it comes to reducing CO2 emissions in order to deliver on the EU's long-term climate goals.
The three decarbonisation scenarios all built on the increasing use of renewables (wind and solar power) and the adoption of the best available technologies (efficiency). The analysis focuses on power plants, refineries and the chemical industry, which together are responsible for more than 90 per cent of the port area's current CO2 emissions.
The decarbonisation scenarios describe how CO2 emissions could be reduced by 75 to 98 per cent in 2050 (compared to 2015). Depending on the scenario, different mitigation strategies are relied upon, including electrification, closure of carbon cycles or carbon capture and storage (CCS). The study includes recommendations for local companies, the Port Authority as well as policy makers. In addition, the study includes a reference scenario, which makes it clear that a "business as usual" mentality will fall well short of contributing adequately to the EU's long-term climate goals.
Distributed cogeneration units are flexible and suited to providing balancing power, thereby contributing to the integration of renewable electricity. Against this background, we analysed the technical potential and ecological impact of CHP (combined heat and power) systems on the German minutes reserve market for 2010, 2020 and 2030. Typical CHP plants (from 1 to 2800 kWel) were evaluated in relation to typical buildings or supply cases in different sectors. The minutes reserve potential was determined by an optimisation model with a temporal resolution of 15 min. The results were scaled up to national level using a scenario analysis for the future development of CHP. Additionally, the extent to which three different flexibility measures (double plant size/fourfold storage volume/emergency cooler) increase the potential provision of balancing power was examined. Key findings demonstrate that distributed CHP could contribute significantly to the provision of minutes reserve in future decades. Flexibility options would further enhance the theoretical potential. The grid-orientated operating mode slightly increases CO2 emissions compared to the heat-orientated mode, but it is still preferable to the separate generation of heat and power. However, the impacts of a flexible mode depend greatly on the application and power-to-heat ratio of the individual CHP system.
