Objectives | The methodology is to call on experienced subcontractors and combine this with design experience of a Hynet multi-consumer hydrogen network. The work will focus on the issues associated with operating such multi-consumer hydrogen networks. Work package 1 – Commercial and Demand. Conducting meetings with potential users to have an initial commercial conversation about connecting to the H2 pipeline and getting an update on potential demand. This updated demand will then be used to update modelling scenarios Work package 2 – End to End Chain Basis of Design. This includes defining key objectives, project stages and scope definition, key interfaces (including hydrogen production and storage interface), understanding Pre-FEED work including key locations and system description (overview e.g Pipelines, AGI and Storage), HSE requirements (Safety Case, COMAH, CDM, DSEAR, National Codes & standards). Key operating parameters, availability, design lifeWork Package 3 – Process BoD. Included within the Process Basis of Design are a Pre-FEED design summary including specific codes, standards and specifications. Specific process elements that will be included are flow assurance modelling requirements, including future connections, boundary limits and forecast flow and consumption/data demand. Other process elements to be considered includes process data (operating conditions, design limits, velocities and fluid properties), odorisation requirements, zoning (including hazardous and process hazard) and operation and control philosophies (pressure control, start-up/shut-down, gas quality, relief and blowdown, isolation, noise abatement, utilities, sparing and metering.Work Package 4 – Pipeline and Facilities BoD. This is a large work package and includes Pipeline control philosophy, pipeline material requirements, QRA and consequence modelling, pipeline design data, network schematic, connections, battery limit. Work will be done looking at and reviewing installation philosophy (including leak protection and pigging etc), commissioning and start-up requirements, logistical constraints and testing and pre-commissioning requirements. The primary scope of this project is the facilitation of a Basis of Design document for the HyNet FEED and consenting which is due to start in the new year. The Basis of Design will cover and consolidate all the work undertaken in the Pre-FEED stage to date and will be handed over to the project team to execute the project. The following areas are included with the scope of this project:Safety and environmental considerations: This includes safety cases identifying major hazards, risk assessments, Major Accident Prevention Document (MAPD). Environmental considerations should relate to Environmental Impact Assessment (EIA) and H&SE environmental plan.Project phases: Any phasing that needs to be considered.Flow Assurance: Line sizing, any necessary flow assurance studies that have been carried out, overview of demand, exit and entry processes, operating design limitations at each connection, overall process macro demand and consumption profilesFlow Process Diagrams: High level PFD, Demarcations of next sections against the PFD, demarcation between facilities and pipelineOperating and Design Philosophies: Introduce overall operating and design philosophies. Including (but not limited to) control of pressure, gas quality, isolation, relief and blowdown, line sixing, noise etc. Other considerations includes operations manning levels, maintenance and inspection philosophy, process control philosophy, power supply/management philosophy, operating and installation philosophyEntry Facility: This section will look to define the entry facility provided at the interface from hydrogen production into the network. A number of different aspects will be looked at including but not limited to process gas specs, process flow diagram, cooling requirements, H2S scrubbing, site layout, site security etc.Hydrogen Pipeline System- Describe the pipeline system to transport hydrogen to end user exit connections. Detail codes, specifications, standards, size throughput and design requirements.Above Ground Installation: Describe the above ground installation to be provided for processing hydrogen gas into the distribution pipeline system as well as storage sitesCommercial Arrangements for Connections: Draft process for connecting to the H2 pipeline is agreed. Also work is undertaking to look at a draft Hydrogen UNC.Define hydrogen demand: Engage with potential consumers to further define hydrogen demand (which will go into the modelling) and look to agree outline connection philosophy. The project will enable a FEED BoD to be developed, which will be further updated during the FEED itself. The FEED BoD will have:Sufficient detail to define the scope of work, Scope of Requirements (SoR) and design data to establish the design basis for the FEED project stageOnce the BoD has been finalised and accepted at the end of the project, there after it will be subject to the project Management of Change Procedure (MoC)The BoD is to be followed and developed further if required by the project team who undertake the FEED. The BoD will be used to establish the scope and detailed design which is to be carried out during the FEEDRefresh the feasibility study hydrogen demand forecasts which underpins the sizing and key connection locations of the planned network.Create a draft hydrogen UNC and connections methodology. It will be necessary to outline the expected connections approach to customers whilst detailing connection and consumption profilesThe BoD will also need to have an interface with other parts of the HyNet project such as the hydrogen production and storage. These interfaces will be managed to ensure that the BoD works alongside these interfaces.This BoD will also look at Policy Resilience. Including the project being categorised as an NSIP and any other relevant policy decisions that need to made at this stage of the project. | |
Abstract | HyNet is a well-advanced, integrated Hydrogen and Carbon Capture Utilisation and Storage (CCUS) project located in the North West of the UK. It has been developed in order to materially reduce regional CO2 emissions from hard to reach sectors of the economy, including industry, heat and transport. HyNet will provide low carbon hydrogen for fuel switching of industrial users and dispatchable power generators, together with injection into the local transmission system (LTS) for blending with NG at key points. Transport fuelling locations can also be served. The initial network will be developed incrementally over the coming decade to serve users with varying demand profiles and connect with hydrogen storage to provide balancing and system resilience. Cadent intends to participate in HyNet by joining the consortium seeking partial funding for engineering design and consenting of the hydrogen distribution assets from the IDC Deployment fund competition organised by UKRI. If successful, Cadent will complete Front End Engineering Design (FEED) and Consenting of Phase 2 of the Hydrogen Distribution network. Cadent is seeking to prepare the Basis of Design (BoD) for the Hydrogen Distribution Network Phase 2 before the IDC Deployment funding is awarded, so that work can commence on the FEED as soon as the main funding is available. | |
