Objectives A site has been identified for the occupied trials, utilising the existing HyDeploy 2 project site, located at Winlaton village in Gateshead. The project will convert houses from 20% blended hydrogen to 100% hydrogen in two stages, starting with an initial phase of 50 homes, utilising the HyDeploy 2 existing infrastructure and equipment following successful delivery of Hydeploy2 trials at the end of 2021. The occupied trial will then move into a second phase converting the surrounding 670 homes including one business, a school and a church that were part of the Hydeploy2 trial.The HyDeploy 2 project utilises a blended hydrogen methane mix up to 20% hydrogen and many of the components purchased by NGN for this project can be re-purposed for the H21 Phase 3 Occupied Trial. The H21 project differs from the HyDeploy 2 project as it is a conversion to 100% rather than a blend and so in order to deliver the H21 Occupied Trial at 100% hydrogen, a different set of prerequisites reviewing and completing where possible prior to the conversion trial. Review and completion where possible of these prerequisites prior to commencing the trial will be covered under this NIA project.The prerequisites include such requirements as:• Legal consents and exemptions;• Confirmation of Hydrogen production and supply;• Surveying of the existing system and homes;• Co-ordinating supply of the required appliances;• Co-ordinating stakeholder engagement;• Duty holders approval.This NIA project will be delivered in two phases. This PEA relates to Phase One and will be delivered in three stages:• Stage 1 – Detailed Review of the Site - To review the site and identify houses to be included in the Trial through Network Modelling. • Stage 2 – Ascertain Prerequisites - Required to assess the prerequisites that require addressing to allow the H21 Phase 3 project to commence.• Stage 3 – Review & Report - To bring together the selection of properties for the initial H21 Phase 3a converting circa 60 houses and Phase 3b converting the remaining >600 properties and confirmation of the prerequisites that require completing, where possible, during Phase 2 of this project. The project scope will include researching and completing, where possible, the following prerequisites to the H21 Phase 3 Occupied Trials project:• Understanding the Legal and Regulatory requirements for running the phase 3 occupied trials:- HSE Exemption for 100% hydrogen;- UNC Derogations;- GS(M)R;- Billing;- Other Legal and Regulatory License Requirements.• Hydrogen production and storage requirement to meet 1 in 20 peak demand and provide resilience:- Identify the most suitable sources of Hydrogen based on site conditions; - Volume of Hydrogen based on calculated demand levels;- Storage requirements.• Modelling for sectorisation and natural gas transition to 100% hydrogen.• Modelling for network sizing to ensure the 1 in 20 can be met i.e. velocities and pressure restrictions encompassing existing mains and services population for the specific area.• Asses other options for temporary provision of heat during supply interruption.• Equipment compatibility across the gas network.• Analyse the Phase 1 QRA output for any mitigation measures, i.e. excess flow valves, meter boxes on external walls.• Liaising with appliance manufacturers for availability of replacement appliances in the required timescales.• Preparation of stakeholder engagement and communication plans. To undertake the required prerequisites to allow the H21 Phase 3 Occupied Trial on 100% hydrogen to be undertaken post completion of the HyDeploy2 project at the end of 2021.
Abstract As part of the overall H21 Project; and detailed in the Executing the H21 Roadmap document, this project will follow Phase 1 of the H21 NIC project and work in parallel with Phase 2 [H21 NIC project
