The main objective is to develop deliverables that will provide a blueprint for the upgrading of all Offtake locations on SGNs network, in support of the Heat Policy reopener. The design will not only identify relevant asset upgrade requirements but will also include timescale recommendations and associated roll out costs.Site survey & problem definitionOfftake sample site selectionFull site survey of selected typical offtake siteTelemetry benchmarked against industry requirements Ofgem FWACVNGGT custody transferReview of ATEX accreditation relevant telemetry Review of SR25 for 2% & 20% hydrogen blendOverview of DSEAR requirements for 2% & 20% hydrogen blendAsset recommendation and testingSite requirement workshopHorizon scanning and benchmarking of relevant metering equipmentLaboratory testing and demonstration of novel technologiesIdentify changes to HPMISReport on identified and recommended asset requirementsHydrogen blend upgrade designApply outcomes from WP2 to inform site specificationHigh level site design for SGNDetailed design to be produced in line with PS/5 & PS/6Design independently appraised and approvedDelivery of roadmap and final reportingApply blueprint design to relevant SGN locations to determine roll out timescalesEvidence process for Ofgem approval for the new CV measurement and a new version of DANINT Detailed CBA for roll out to three SGN LDZsFull report to inform Heat Policy Reopener application In order to ensure SGN are able to meet the challenges associated with accepting blends of hydrogen through the relevant Offtake sites, the project will seek to assess and review onsite assets, carry out relevant laboratory testing to ensure existing equipment can perform the required functions and, if necessary make recommendations for further calibration requirements, asset upgrades and/or new metering installations. Further to this, considerations will be given to SR/25 hazardous area drawings, ATEX ratings of equipment, SCADA upgrades, DSEAR considerations and changes to HPMIS.A site-specific, detailed design will be produced, compliant with TD/13 and appraised and approved in line with SGNs PS/6 process. This design, although site specific, will comply with PS/5 to provide a blueprint for the upgrading of all Offtake locations on SGNs network, in support of the Heat Policy reopener. The design will not only identify relevant asset upgrade requirements but will also include timescale recommendations and associated roll out costsThe approach adopted in this project is potentially repeatable at other similar sites across GB, however this project will mainly focus on SGNs asset configurations and create blueprint designs for hydrogen conversion of this specific asset groups The objective of this project is to determine the impacts of 2% and 20% hydrogen blends on SGNs national offtake sites. By undertaking an assessment and review of a specified number of sample sites, Kelton will produce a site-specific blueprint design compliant with TD/13 and appraised and approved in line with SGNs PS/6 process. This will provide a roadmap for the upgrade of all SGN offtake locations.
