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

 

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.
