Introduction to HyDeploy
To demonstrate for the first time that a blend of hydrogen and natural gas can be distributed and utilised safely & efficiently in the UK distribution network without disruptive changes for consumers.
Project Objective
Project Funded under OFGEM’s Network Innovation Programme
Why Blending Hydrogen?
Blending hydrogen into the gas grid delivers low carbon heat to customers without requiring disruptive and expensive changes in their homes
Blending 20% hydrogen into our existing gas grid would save as much carbon as
removing 2.5 million cars from the roads
Developing the science base, regulatory position, supply chain and customer perceptions of hydrogen`
Non disruptive
Material savings
Pathway to deeper savings
Blending is gaining recognition as an important element of the energy system
Why Keele?
• Under its Smart Energy Network Demonstrator (SEND) programme, Keele is at the forefront of energy network research
• The gas grid at Keele is particularly suitable for this project as it is self-contained and the buildings served are typical of a small town
• Keele is licensed transporter & supplier of gas to those customers. It is their gas network that they own and operate
• Provides a tightly managed context for a first of a kind project
600 acre site
Gas Safety (Management) Regulations GS(M)R
• Currently GS(M)R governs gas quality in the UK grid
• In order to transport a hydrogen blend in the gas grid, a specific Exemption is required to GS(M)R, which can only be granted the HSE
• Exemption can only be permitted only if the health and safety of persons likely to be affected will not be prejudiced by increasing the hydrogen content of the gas conveyed

EU Projects
• Having a strong regulatory framework is a valued enabler, not an impediment
• Extensive & constructive engagement with HSE throughout the process
• The application underwent challenge and review with the HSE regulatory & Science Division with over 140 clarification questions
• Excellent sessions with probing questions. This requires resource
• Exemption granted swiftly - in around 4 months

Team
Overall project lessons & attributes • The level of evidence required by the HSE to
evidence the safety case should not be underestimated
• Foundational evidence has been developed –for HyDeploy, and wider hydrogen adoption
• All Ofgem SDRCs to date have been successfully delivered
• The project is held in high regard by stakeholders in the UK and internationally
• Advisory Board complimentary about the quality of work & the value of this project in informing future heat policy
Overall
Technical Lessons Learned • This is necessarily an Exemption to deliver
a hydrogen blend into the specific site at Keele for a trial period only
• Manage the complexity for a First of a Kind project
• The focus of much of the work has been to ensure that the evidence for ‘no change’ is robust. This is often more arduous than justifying a specified change
• A summary of the key scientific/technical findings will follow in the next presentation
Procedure Lessons Learned • All applicable procedures have been
comprehensively reviewed and assessed for the Exemption
• The outturn changes to procedures are relatively limited
• Demonstrating that existing procedures are safe and suitable is a considerable task - even if the final outcome does not appear significantly different
• Operational deliverability & training is key
• A collaborative forum of operational knowledge combined with analytical science is invaluable
QRA Lessons Learned • The detailed 200+ gate/event Quantitative Risk
Assessment is central to the Exemption
• Available gas industry data is not always as detailed as would be ideal
• The most challenging task is translating core scientific findings into quantitative data for QRA
• As planned, at Keele conservative positions on inputs could be taken, where evidence is currently more limited. Compensated with specific mitigation measures, given the site & available controls
• For public network operation, evidence base must be extended, so the assessments of risk can be more precisely drawn; requiring less conservatism. Necessary as fewer specific measures can be applied
Customer Lessons Learned • Learning from best practice, the project
achieved excellent customer engagement
• A dedicated customer liaison officer; passionate about the project and addressing customer needs
• Feedback positive & good access achieved
• Don’t underestimate the time and effort to communicate with customers
• The ‘few’ require the ‘majority’ of the effort
• Issues are often not ‘project’ related
• Timing of engagement is important
Team Lessons Learned • The team is well formulated, complementary
and is delivering high quality work effectively • The marriage between scientific rigour and
practical experience is critical for success • Formalised governance arrangements from
separate teams within HSE/HSL worked well • Communicating assessments of complex risk
profiles effectively through organisations is important
• Internal project reporting processes provide visibility to enable informed decisions
• Collaborative engagement with other projects enables sharing of information & best practice, avoiding duplication and improving outcomes
Objective: Building on the foundational work at Keele University to demonstrate on public distribution networks that a blend of hydrogen and natural gas can be distributed and utilised safely & efficiently in the UK distribution network without disruptive changes for consumers.
Outcome: That a supplier of hydrogen is able to apply & inject hydrogen into a gas distribution network, just as biomethane producers can today.
