To undertake a feasibility study that will examine the financial and economic impacts of repurposing infrastructure for hydrogen, the technical considerations that will need to be addressed as well as a deployment route to its implementation.The deliverables from this commission will take the form of a report and a supporting digital asset based upon geospatial data and Geographical Information System (GIS) files. This provides an interoperable platform to support future project stages including detailed design and planning, through to operation.The report will include a set of recommendations for next steps in the development process.Aspects considered are: Business case Identification of carbon saving Benefit cost assessment Outline reference design / technical concept Indicative costs Stakeholder views Road map Next Steps The feasibility study will be examined over four phases.1. Discovery Phase: This stage would be used to gather As is data, and to inform vested stakeholders of the projects goals. We would undertake the following tasks during this phase: A review of the gas network to meet heating demand (this includes distribution and transmission gas networks) Technology for separating hydrogen from a hydrogen / methane blend Geological review of IoG An assessment of potential hydrogen users in the area, including TfL Stakeholder Engagement including identifying Initial stakeholders and ecosystem mapping Examine commercial arrangements required for investment purposes and how this would develop over time to a wider use of hydrogen for transport and heating in the London area. 2. Design & Modelling Phase: Our study will provide an outline reference design of a hydrogen gas network linking into London from the IoG, and present this in diagram format, indicating the major component parts and sequencing. We will also outline the indicative costs associated with the options examined. We would undertake the following tasks during this phase. Technical concept development Production, CCSU (if needed), Pipeline, Storage, identifying modifications that would be required to the network and how much might this might cost. CO2 reduction - its implications on health costs, contribution to Clean Growth Strategy Business Model / Business case -Our modelling will assess a number of development scenarios, considering the volume of hydrogen production over time, TfLs capacity as an end user, the ability to distribute and use hydrogen locally End state future vision of hydrogen in South London (aligning with BEIS & element energy vision work on the future of Londons energy landscape). 3. Analysis Phase: This phase will analyse the options and costings developed during the Design and Modelling Phase in greater detail, in order to provide the parties with a preferred solution. This would include the following tasks: Refinement of cost estimates Wider economic benefits: Examine commercial/funding - the provision of subsidies equivalent to green electricity What regulatory arrangements would be needed? Road map & modular design Stakeholder and communications 4. Completion Phase: During this phase the study will be concluded, developed and the final report presented. This phase will also include: Report on Lessons learnt Final report with recommendations Outlining Next Steps that may include Reinforcing the transmission network for hydrogen Reinforcing the existing distribution network for hydrogen Determine the viability of utilising existing infrastructure to enable the Isle of Grain region to supply decarbonised hydrogen to London and the South East. Ascertain what additional infrastructure would be required if the Isle of Grain was to supply all of Londons hydrogen, including the identification of critical environmental issues and ecosystem mapping of stakeholders. Generate a reference design showing the outline of a hydrogen system linking the Isle of Grain to London and the South East Generate a business case showing the economic and environmental benefits to consumers and UK PLC Develop a roadmap with next steps for hydrogen development in the region

To undertake a feasibility study to help support the potential of the Isle of Grain as a location for hydrogen production and storage.
