Carbon Capture, Usage and Storage (CCUS) and hydrogen are likely to play an essential role in helping the UK achieve net zero by 2050. For example, our analysis suggests that around 270TWh of hydrogen could be needed across the economy by 2050, which could increase considerably depending on application across heat and transport sectors. Low carbon hydrogen could be produced through gas reformation with CCUS, electrolysis, or biomass gasification. The precise split of this across end uses will depend on a variety of factors including cost, availability and technical application.
