capacity. Excess

hydrogen being blended

into the distribution

network.

Phase 1- Demonstration

project for hydrogen

blending within a local

network. 600 acre site at

Keele University.

Heavily focused on the

safety case and impact

to end users.

Phase 2- Trials on 2

public networks in the

North of England.

Hydrogen across the Gas Distribution Networks (GDNs)

Convert the entire city

of Leeds to hydrogen by

2026. Then rollout

across the North of

England. Supply of

hydrogen from Steam

Methane Reformers at

Teesside. The project

would require appliance

conversion, hydrogen

storage and CCS.

Building new PE assets

to run on hydrogen.

Earlier stages include a

demonstration network

and household

conversion. The project

would address many

safety concerns relating

to hydrogen

As with any major technological change, hydrogen

brings a host of challenges for the energy sector:

Future of the NTS

However, Hydrogen brings a lot of opportunities. We

need to understand the role the NTS can play:

Investment and Affordability £

Reduced reliance on electricity transmission

Introducing

National Grid | A role for the NTS in a hydrogen transition

HyNTS encompasses all of our work relating to hydrogen across

our business and wider industry. Ongoing programmes include:

Feasibility of

Hydrogen in the NTS

A feasibility study with

the aim of

determining the

capability of the NTS

to transport hydrogen.

Includes a review of

relevant assets,

pipeline case study

and draft scope for

offline trials.

Project Cavendish

A review of the

potential of the Isle of

Grain region to use

existing infrastructure

to supply hydrogen to

London & the South

East including

generation, storage,

transport and CCS.

Aberdeen Vision

A feasibility study for

the generation of

hydrogen at St

Fergus using the NTS

(up to 2%) to supply

the city of Aberdeen.

Includes generation,

injection, separation

and transport.

Deliverables

• Capability assessment: Review of the physical

capabilities of the NTS

• Standards review: Evaluation of existing hydrogen within

the UK and Europe and gap analysis for NTS

• Live trial optioneering: Evaluation of a range of potential

candidates for a Stage 2 offline trial.

• Draft scope for offline trials: Scope cover a wide range

of assets to test assumptions of the capability assessment

Case Study:

Gas Unie Hydrogen Pipeline



Owned by Gasunie Waterstof Services (GWS) a 100%

subsidiary of N.V. Nederlandse Gasunie

12,4 km pipeline:

11,7 km 16" (previously natural gas 66.2 bar (e) from 1996)

700 m 12" (new)

Typical gas composition of 70% vol. H2 and 30% vol.

CH4 at approx. 35 bar(e)

No compression or metering by GWS

Adjusted maintenance, repair & emergency procedures

because of gas properties (ignition, volatility)
