Objectives	A site has been identified in NGN for occupied 100% Hydrogen conversion trials, utilising the existing distribution network. This NIA is to undertake appropriate research and review of the previously developed research within NIA_NGN_268. This review is to analyse the potential intervention areas including the additional requirements for Hydrogen Production and storage that could prevent or delay progression to a safe and secure future trial.  To undertake a desk top review and assessment of the two documents developed under NIA 268 – Occupied Trials to identify any potential intervention areas within the assessment of documentation in relation to GSMR and Safety case exemption Phase 3 NIA output table H21 Phase 3 Work Packages - 1.2 Identify and scope the work required to gain HSE exemption - 1.4 Identify and scope GSMR work required The scope is limited to reviewing the two-documents above and providing an output report of any potential gaps for NGN consideration and further assessment.  Providing an output report of any potential gaps for consideration and further assessment that also indicates potential costs and timescales to address any gaps. The objectives of the is project following a review of the research and documents generated under the first phase of the project. We will be working to provide an output report of any potential gaps for consideration and further assessment to enable a future live trial.
Abstract	The H21 project aims to demonstrate the feasibility of using 100% hydrogen in a GD network and as part of the layering of confidence to the stakeholders and the HSE, to provide this we require expert assistance and assessment on gaining an Exemption from our current gas safety case. Therefore, NGN have requested Pipeline Integrity Engineers (PIE) to undertake a review and assessment of the documents developed to identify any potential intervention areas within the assessment of documentation in relation to GSMR and Safety case exemption. A key point from this assessment is to identify any potential gaps within the assessment of documentation in relation to GSMR and safety case exemption in order to operate a 100% hydrogen converted natural gas network.
