I see it as oil companies being more CO2-efficient. Of course it doesn’t solve the fundamental problem or continuing to emit CO2.

It’s not as negative as it could be. If oil companies didn’t have captured CO2 for EOR, they would use natural CO2 (from geological reservoirs) or CO2 generated by burning natural gas for this purpose.

Don’t we have this information? One could come up with an infographic or animation showing that the slope of change of temperature and CO2 is orders of magnitudes different. I work in industry and often find that marketing people react more when the graphs are spectacular.

Who is pushing for hydrogen in homes? Hydrogen should not be more dangerous than natural gas. It is odorless but that can be solved, either by adding an odorant impurity or relying on sensors rather than human senses.
