Consultation description

This consultation seeks to gather evidence to help inform our assessment of the potential strategic and economic value of blending hydrogen into the existing GB gas transmission network. It sets out our assessment of the aspects of commercial, market, technical and billing arrangements that would be needed to accommodate hydrogen blending into gas transmission networks, should blending be supported and enabled by government.

It also considers the implications for existing end users of gas directly connected to the transmission network and developments across Europe in relation to the EU Hydrogen and Decarbonised Gas Market Package. We are seeking stakeholder views on this current assessment of blending, including the economic analysis and whether any complexities and challenges could be mitigated.

The consultation is open to all, but we expect it to 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
