Hydrogen Blending into GB Gas Distribution Networks

Closed 27 Oct 2023

Opened 15 Sep 2023


Hydrogen blending refers to the blending of low carbon hydrogen with other gases (primarily natural gas) in pre-existing gas network infrastructure and appliances. We are assessing whether there may be value in having hydrogen blending available to support the early development of the hydrogen economy. 

The government previously explored the potential strategic role of hydrogen blending as part of the consultation on Hydrogen Transport and Storage Infrastructure in 2022. We are now seeking further stakeholder views to help inform our assessment of hydrogen blending’s potential strategic and economic value and lead options for its implementation, if enabled. This will help to inform a strategic policy decision on whether to support blending of up to 20% hydrogen by volume into the GB gas distribution networks.

The consultation contents are as follows:

  • Nature and scope of blending policy decision
  • Strategic role of hydrogen blending
  • Commercial support models
  • Market and trading arrangements
  • Technical delivery models
  • Gas billing arrangements
  • Economic analysis

This consultation is open to all, but we expect will be of most interest to stakeholders involved in the hydrogen economy and natural gas networks, including:

  • Hydrogen producers
  • Hydrogen consumers
  • Gas transporters
  • Gas shippers
  • Gas consumers
  • Storage operators
  • Investors
  • Consumer champions
  • Trade associations
  • Academics

What happens next

The Department for Energy Security and Net Zero will analyse all consultation responses to address any relevant points made by stakeholders to ensure we can fully achieve our policy aims.

On-going engagement will form an important part of our work. We intend to continue to engage with stakeholders such as through working groups and bilateral meetings.
