Objectives	The aim of the proposed work is to assess the operational envelope of hydrogen injection up to 20% by volume under the existing regulatory regimes. The objectives are as follows: Establish a suitable Case Study to illustrate the likely operational envelope given the regulatory constraints. The case study suggested is to assess impacts on the North West LDZ and assume hydrogen injection at one or more offtakes or locations in a lower pressure tier. Illustrate any constraints on hydrogen content for different locations of injection within the current regulatory regime, (assuming an exemption to GSMR is in place allowing up to 20% h2 by vol.) Illustrate any constraints on biomethane content for different locations of injection within the current regulatory regime.Establish either one or two case studies for other LDZs. This would permit an assessment of impacts across the UK a)Construct a model of daily LDZ energy flows, daily LDZ volumes, daily flow-weighted averageCVs for each day in a selected year. The model will assess hydrogen and biomethane injectionat NTS offtakes and into lower pressure tiers. The model will permit identification of calorificvalue (CV) constraints associated with the existing billing regime set by the GasCOTEregulations, and Wobbe index (WI) constraints set by the GSMR.b) Populate the model with daily data for an LDZ and assess hydrogeninjection at NTS offtakes to determine the likely operating envelope initially (when natural gas is the dominant gas conveyed) and in future scenarios (where biomethane and hydrogen are dominant). The objective of the project is to understand the impacts of blending hydrogen into a GD LDZ to understand the operational envelope and any limitations on hydrogen or biomethane content allowable in the gas stream under the current and proposed regulatory regimes.
