Up to 5% hydrogen blend

Blending up to 5% hydrogen by volume helps to reduce the amount of carbon dioxide produced by the gas network.

This scenario assumes small amounts of blending across the network within the framework of the current flow weighted average CV process (FWACV).

Low impact on CDSP systems

• Introducing hydrogen at this level represents a small-scale, low-risk step towards decarbonisation, with minimal impact on CDSP systems.
• Provided the CV of the blended gas remains within FWACV tolerances, only limited system changes are expected.
• If differentiation between blended and non-blended gas is required, new CDSP data items would need to be developed.
• Overall, this scenario is a manageable transition that can be delivered within existing network and billing frameworks.
