A new software tool named SCO2T helps quickly find good spots to store lots of CO2 underground. It looks at many underground places and figures out how much CO2 each can hold and how much it might cost to store. The tool also links how fast CO2 can be put in the ground and how big the storage area might be. By studying various aspects like depth, thickness, and permeability of underground formations, they found that deeper and more permeable places can store more CO2 and cost less, while higher porosity makes storing cheaper without affecting the injection rate. This tool can be very helpful for capturing and storing CO2 to fight climate change and could lead to better, cheaper ways of keeping the planet healthy.
