This is called Carbon Capture and Storage and so far it has never been worth it energetically. And the only companies doing it are oil companies in a process known as enhanced recovery which pushes more co2 out than is pushed in. The OP was right. Better to leave it in the ground
You can have 100% renewable energy. You can't realistically produce cement or steel without using and exhausting large amounts of CO2. This has to be addressed, even if it costs energy (which, as we agreed, can be 100% carbon-neutral).
