Climate change is the greatest challenge of this century. Reducing greenhouse gas emissions and the transformation to a low-carbon economy are high on the political agenda. Renewable energy, electrical energy grids and CO₂-based technology are essential to realize this paradigm shift. An important CO₂-based technology is 'Carbon Capture and Utilization' (CCU), which converts CO₂ into useful chemical building materials. The share of renewable energy will increase significantly during the energy transition, ultimately leading to predominantly renewable energy production. However, this introduces new challenges to keep the electrical energy grid reliable and stable. Moreover, this increases the tax on traditional power plants to balance production and consumption. Consequently, the system must become more flexible and adaptive in order to cope with an increased share of renewable energy and energy-intensive CO₂-based processes. More specifically, a control and decision system was developed in this PhD to optimally combine a chemical CCU process with wind energy to support the electrical energy grid as a hybrid system. This research therefore makes a valuable contribution to the development of the future energy grid with a high share of renewable energy sources.
