Low Carbon Hydrogen Well-to-Tank Pathways Study
A report for Zemo Partnership prepared by Element Energy
Project Aims
- Hydrogen is a potentially vital fuel in the UK’s plan for meeting its decarbonisation
targets in the mobility sector for 2050. However, 99% of UK hydrogen today is ‘grey
hydrogen’ and is not low carbon. - In order to effectively appraise hydrogen’s value in decarbonising transport and
develop appropriate policy, UK decision makers need a clear and transparent
evidence base of hydrogen’s lifecycle emissions. This work has been instigated due
to a lack of data specific to the UK on the carbon intensity (GHG emissions) of
different low carbon hydrogen pathways. - The study had the following aims:
- To identify the range of hydrogen production, distribution and dispensing
options that are emerging - To provide an exhaustive, transparent and up-to-date analysis of the
emissions and energy use related to different low carbon hydrogen pathways
(Well to Tank), considering feedstocks, production, distribution and
dispensing - To identify the key sensitivities influencing the carbon intensity of the
pathways considered - To create an Excel model to contain this data and allow users to easily
explore the impact of a range of scenarios and sensitivities on full H2
pathway emissions - This work will serve as the evidence base for decision and policy makers
- To identify the range of hydrogen production, distribution and dispensing
This report provides a clear overview of the key findings and was delivered by Element
Energy for Zemo. The study benefited from input from Zemo members and the wider
UK supply chain.
