Safe pump technology from HERMETIC contributes to Carbon Capture and Storage (CCS) value chain

In March of 2023, CO₂ has been stored underground for the first time worldwide, and on a transnational basis, within the scope of project “Greensand” to counteract the effects of climate change. This project demonstrates how CO₂ emission sources can be combined with suitable CO₂ storage areas. Canned motor pumps from HERMETIC-Pumpen GmbH are used within the scope of the CCS value chain, which involves the separation of carbon dioxide, its transportation and the geological storage of CO₂ below the seabed.
