There is uncertainty about the extent to which blue hydrogen can play a role in a Net Zero economy in the mid to long term, even if it may be cheaper and ready to deploy in certain industrial settings sooner than green hydrogen, as some industrial users already possess the necessary infrastructure. The Government should not be dependent on either blue or green hydrogen alone in the short-term. The Government’s decision to continue using blue hydrogen should be dependent on the standard CO₂ capture rate reaching 95% by 2030 and in excess of 99% well in advance of 2050. In its response to this Report the Government should set out its expectations of how much CO₂ could be captured in hydrogen production and which industrial settings it sees as being ready to utilise blue hydrogen prior to 2050.
