The objectives of this work package are:
- Investigate the techno-economic, environmental, and reliability performance of (i) early mover CCUS and CCTS chains with foreseen implementation in the near-term (e.g., before 2030), and (ii) of a Swiss CO2 network interconnected to an EU-wide shared infrastructure as long-term solution.
- Develop scenario-based roadmaps of Swiss CCUS and CCTS infrastructure rollout over time compatible with Swiss climate and energy goals and industry roadmaps.
- Assess optimal integration options for post-combustion CO2 capture technology in Waste to Energy (WtE) and cement plants with reference to specific Swiss emitters and generalization to other plants.
- Explore how to build viable business models that support the implementation of CCTS and CCUS technologies for the WtE, cement, and chemical and pharma sectors.
The overall purpose of this WP is to assess the upscaling potential of carbon capture, utilization and storage (CCUS) and carbon capture, transport and storage (CCTS) chains in the near term as well as that of a CO2 network connecting Swiss emission sites to national and international storage sites in the long term. In the following, CO2 supply chains that involve CO2 capture and transport abroad for geological storage are referred to as CCTS, while CO2 supply chains that involve CO2 capture and usage and storage in concrete via mineralization are referred to as CCUS.
First, we will focus on the analysis of few Swiss point-source emitters from the WtE, cement and biogas sectors (e.g., KVA Linth, ERZ plant in Hagenholz, Jura cement plant in Wildegg) that may deploy CCUS and CCTS as an emission mitigation solution in the near-term, e.g., before 2030. This work will consider the overall CO2 supply chain with CO2 capture and liquefaction at the emitter’s site, transport, and storage in concrete (domestic solution) or in a geological reservoir abroad. Because of the near-time horizon, it is expected that these supply chains will mostly rely on CO2 transport by truck and train.
In a next step, the development and optimal integrated design of a CO2 network interconnected to a pan-European shared infrastructure will be investigated as a long-term emissions mitigation solution. The analysis will be extended to other sectors, i.e., chemical, pharma, and life sciences sectors.
Such a network will serve the Swiss point-source emitters and will include Direct Air Capture (DAC) units, whose optimal location with respect to operational CO2 storage hubs abroad will be investigated. Finally, the optimal integration of post-combustion CO2 capture with WtE and cement plants will be evaluated with reference to the Jura Cement plant in Wildegg (Aargau) and the ERZ WtE plant in Hagenholz (Zürich), and guidelines will be provided to generalize the outcomes of this analysis to other Swiss emitters from these sectors.
