In August 2022, for the first time ever, CO2 captured from a waste-water treatment plant in Switzerland was transported to Iceland for injection and mineralization in geological formations underground in the context of the pilot project DemoUpCARMA.
The choice of Iceland as a storage site, which significantly extends the length of the transport route, is no coincidence. Research projects have shown limited potential for storing CO2 in geological storage formations in the near future in Switzerland. Therefore, exploring alternative storage options is critical. After capturing the CO2 at ARA Bern, the CO2 is liquefied and loaded onto portable ISO containers with a capacity of 20 tons, which can keep the CO2 in a liquid state until arrival at the storage site. The ISO containers are transported via truck from ARA Bern to the train station in Weil am Rhein. From there, the CO2 is transported first via rail to Rotterdam and then via ship to Reykjavik. Once delivered in Reykjavik, the ISO container is transferred to the injection site via truck.
