E-methanol provides an option of carbon-neutral mobility, as it is readily to be consumed directly by diesel and gasoline engines, as well as by fuel cells of electric vehicles. In addition, methanol plants can be integrated into existing industrial facilities such as green hydrogen, biogas, and district heating to create sector coupling and CO2 neutral closed loop industrial ecology. However, green hydrogen supply capacity depends on renewable electricity energy sources, which poses several supply reliabilities challenges for green hydrogen, and e-methanol plants, due to power output and energy prices fluctuations.
Addressing the challenges, project “Kassø” will build Power to X (PtX) supply chain that consist of a network of green hydrogen, biogas, and district heating to create sector coupling and CO2 neutral closed loop industrial ecology. The PtX plant will be constructed at Kassø, in Southern Denmark. Simulation and optimization models are developed to build a supply chain wide digital twin of the PtX plant at Kassø. The simulation model consists of hard infrastructure (transporters, end users of methanol, storage tanks, pipelines, biogas, electrolyzer and methanol reactors, and distillation columns, heat pumps, district heating plant), and soft infrastructure (data analytic tools) to synchronize information and materials flows in the supply chain. The project will act on the following activities:
- Investigation of utilization of Power to X waste heat in district heating by developing agent-based simulation of Danish District Heating ecosystem.
- The development of simulation and optimization models of an integrated system of green hydrogen system.
- The development of agent-based simulation of power-to-methanol supply chain, integrated to district heating, by utilizing carbon from renewable resources.
- Prototyping of digital twin of power-to-methanol supply chain, integrated to district heating, by utilizing carbon from renewable resources.
