- The plant will process 4,000 tons of CO2 annually.
- Around 90% of CO2 produced, up to 3,000 tons annually, will be captured.
- The liquid CO2 will be stored and sold on the national market.
- Residual methane will be eliminated in the purification process.
Project Overview
CO2 Energie AG, a subsidiary of Regionalwerke Baden and Recycling Energie AG, is collaborating with Hitachi Zosen Inova and ASCO Carbon Dioxide LTD. to develop a CO2 separation and liquefaction plant at an existing biogas facility in Lenzburg, Switzerland. This initiative aims to make renewable CO2 available for industrial applications, reducing reliance on fossil CO2 and supporting global climate protection efforts.
Plant Capabilities
The new installation will capture CO2 that was previously released into the atmosphere, processing up to 4,000 tons annually. The CO2 will undergo filtration and dehydration under high pressure, promoting efficient utilization and substituting fossil CO2. The plant will capture around 90% of the CO2 produced, amounting to up to 3,000 tons annually.
Environmental Impact
Recycling Energie AG and RWB have previously collaborated in Nesselnbach, producing biogas for the regional natural gas grid. The new plant will further enhance sustainability by capturing and processing CO2 into liquid form, eliminating residual methane and minimizing environmental impact.
CO2 Utilization
The liquid CO2 will be stored in large tanks and collected by Messer Schweiz AG for sale on the national CO2 market. Applications include industrial processes, medical technology, and beverages in the food industry. This reduces the need for additional fossil CO2 production or imports.
Future Prospects
The collaboration between Hitachi Zosen Inova and ASCO Carbon Dioxide AG marks a significant step towards sustainable energy solutions. Further joint projects for Carbon Capture Utilization & Storage (CCUS) are already planned.
