Blue hydrogen is also produced with natural gas or meth-ane, but the process relies on carbon capture, utilisation and storage (CCUS)to trap and store CO2 emissions. Blue hydrogen is sometimes referred to aslow-emission hydrogen. But it is crucial to note blue hydrogen productionfrom fossil gas releases upstream and midstream GHG emissions, risks con-tributing to methane leakage, and often does not contribute to long-termcarbon sequestration as most active projects utilise captured carbon for en-hanced oil recovery3

In fact, capturing CO2 from ethanol production is so easy that ethanol production is the biggest source of purified CO2 in the US, and the second biggest source in Europe. This is where we source the CO2 that we use in fizzy drinks, food production, fire extinguishers, etc.

2030, capturing around 125 Mt CO2 per year

There are now around 40 commercial capture facilities in operation globally, with a total annual capture capacity of more than 45 Mt CO2.
