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

Procedures

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.
