Objectives The project will involve five main work streams including the following: An evaluation into a number of options for hydrogen supply identifying associated engineering and civil costs to determine the optimal solution for the Grangemouth to Granton, live pipeline trial. Development of a route map and methodology to detail how the existing GB LTS network can be repurposed for use with 100% hydrogen, and utilising a live demonstration project to repurpose the existing Grangemouth to Granton pipeline and associated installation, and additional testing in the HYNTS FutureGrid experimental research programme being progressed by National Grid at Spadeadam. Illustrate the statistical representativeness of the Grangemouth to Granton pipeline and cost effectiveness of hydrogen conversion, complete severity analysis on the GB LTS pipeline materials, and produce a comprehensive testing approach for offsite testing of LTS assets..Undertake land referencing activities for repurposing of the Granton to Grangemouth pipeline to 100% hydrogen. Feeding from outputs of workstream 1 on potential options for hydrogen supply for the trial of the Granton to Grangemouth pipeline, one option is a pipeline from a Steam Methane Reformer (SMR) located in the Grangemouth industrial cluster. This investigate the feasibility of routing the 100% hydrogen pipeline from the refinery to gas network. Work streams 4 and 5 have been recently developed following discussions and agreement with OFGEM to bring aspects of LTS Futures programme forward to keep momentum on the programme and the NZASP funding decision does not affect timelines. The scope and objectives of the Project should be clearly defined including the net benefits for consumers (eg financial, environmental, etc). This section should also detail the financial benefits which would directly accrue to the GB Gas Transportation System and/or ET or distribution. Hydrogen OptioneeringInitial discussions with SGN and Grangemouth refinery to set boundaries of the study and identify available options CAPEX and OPEX of hydrogen options ranging from: Routing of pipe within refinery (2inch and 18inch) from SMR production to Granton to Grangemouth pipeline.Choice of pipeline material and operating pressureEquipment required for injection from tube trailerFunctional specification of PRS Odorization unit specification Specification of purging systems from nitrogen to hydrogenCommissioning planDecommissioning plan Liaison with SGN and review test programmeOverall cost estimateRepurposing StrategyDevelop technical strategy and the work programme and plan to deliver it Define technical studies required including hydrogen release studies and equipment trials to establish scope of further works Conduct parametric variable analysis of the UK LTS system, which enable understanding and demonstration of the applicability of the R&D programme to the whole LTS network. Carry out Value for Money analysis to identify if repurposed pathway provides the best value for money for the whole system.G2G Statistical RepresentativenessDetermine the statistical representativeness of the Granton to Gangemouth pipeline against the GB population of LTS infrastructure Determine the cost effectiveness of hydrogen conversion of the LTSComplete a severity investigation to ensure the worst case materials are covered for material testing allowing for prioritisation of material testing. Gap analysis to confirm that the LTS Futures programme of testing covers all the evidence gaps but considers new evidence to be generated by the FutureGrid programme of work to avoid necessary duplication Define a high-level approach for testing LTS assets alongside/between the existing H21 and FutureGrid projects at DNV SpadeadamLand referencing for 100% hydrogen pipelineLand referencing to understand the effects on the landowners are along the 100% hydrogen Grangemouth to Granton pipeline and identify any previous interactions 100% Hydrogen pipeline supply designFeasibility study to supply hydrogen from the refinery to gas networks, the project will:complete of a utilities survey to understand any existing utilities lines that may cross the potential route of 100% hydrogen pipeline from the hydrogen supply (SMR) to the Grangemouth to Granton pipeline.Desktop ground investigation to decide upon pipeline routing techniques (e.g. HDD or micro tunnelling) for the 100% hydrogen supply pipeline A topographical survey will be completed for the 100% hydrogen supply pipeline Geotechnical investigation will be completed for the 100% hydrogen supply pipeline Internal camera inspection of Grangemouth pig trap to locate hydrogen supply tie in The objectives of the project are to undertake preparatory works for development of the live trial of the Grangemouth to Granton pipeline under the LTS Futures programme. The project will illustrate the pipelines statistically representative nature to GB LTS infrastructure, identify a clear strategy for the repurposing of LTS assets and identify the material testing strategy based on severity of the materials in the GB LTS pipelines. Potential routing and design of a hydrogen supply pipeline will also be completed post decision on the most cost-effective approach for hydrogen supply for the trial. All work programmes will be key in developing the live trial of the Grangemouth to Granton pipeline and will feed into the blueprint for repurposing. 
Abstract The UK government has committed to reducing greenhouse gas emissions to Net Zero by 2050. All future energy modelling identifies a role for hydrogen in providing decarbonised energy for heat, transport, industry and power generation. A key element of transition to hydrogen is to deliver compelling evidence for the enduring use of existing gas network assets in the form of a pathway to decarbonisation. This project seeks to undertake critical work to ensure completion of a live field trial in a statistically representative pipeline. The LTS programme seeks to develop a blueprint for repurposing of LTS pipelines for hydrogen transmission whenever, wherever. Project findings will be key to support the transition to 100% hydrogen.
