Introduction: The project will seek to explore the current commercial regime and how it will need to be adapted to allow hydrogen blending.

Objectives: The objective of this project is to understand the changes required to the current commercial market to deploy hydrogen blending across Transmission and Distribution networks. With consideration of
• Injection from 100% Hydrogen networks like HyNet.
• Blended injections from other networks e.g. NTS.
• Interaction between distribution grid and the NTS, in terms of controlling offtake flows and the potential for hydrogen blends coming off/on to the NTS, including the need to potentially instruct hydrogen producers on another network.
