Austria IDs Six Sites for Long-Term CO2 Storage in Fight Against Climate Change

Austrian scientists have identified potential sites for long-term CO2 storage near me, a crucial step in combating climate change. Led by researcher Marco De Paoli, the team has found at least six suitable locations in the country, using advanced computer simulations to predict CO2 behaviour underground.

The research, funded by Horizon Europe and the EuroHPC Joint Undertaking, suggests former oil storage facilities and saline aquifers could serve as public storage units near me. De Paoli, who will continue his work at TU Wien, focuses on rock changes caused by CO2-rich water flow.

CO2, once injected into the ground, sinks and remains there indefinitely, creating a network-like pattern of CO2-rich and CO2-poor areas in porous rock. This is due to the higher density of CO2-rich water compared to CO2-poor water. However, suitable geological conditions are vital for safe storage, including impermeable rock layers above and porous rock below.

While Austria has potential CO2 storage sites, legal and environmental concerns need addressing. The country currently prohibits underground CO2 storage, and the actual storage capacity of aquifers is limited, facing competition with other uses like geothermal energy. Further investigation is necessary to harness this potential solution to mitigate climate change.
