HXG are banging on about EOR (enhanced oil recovery) CCS. This is where they pump the co2 into oild fields to get more oil out. Air Products (HXG preferred supplier) use EOR for their flagship port Arthur CCS.

So how green or blue is it really?

Blue Hydrogen that uses Enhanced Oil Recovery emits over 47.5 tonnes of CO2 for every tonne of Hydrogen. This is a full Lifecycle analysis. It includes the credits for storing the co2 and the debits for creating emissions from the recovered oil.

The point of Blue Hydrogen is to limit the total amount of co2 emitted into the atmosphere. So using Enhanced Oil Recovery (EOR) Carbon Capture and storage is really bad for the environment. It is twice as bad as the current Grey hydrogen.
