Overview of the UK Cluster-Based Hydrogen Strategy

The United Kingdom has adopted a regional cluster-based approach to hydrogen deployment, targeting decarbonization of heavy industrial zones. This strategy integrates low-carbon hydrogen production with carbon capture, utilization, and storage (CCUS) to reduce emissions from sectors such as steelmaking, chemicals, refining, and cement. Two flagship projects—HyNet in the Northwest and the East Coast Cluster in Teesside and Humberside—exemplify this model, leveraging existing infrastructure and shared resources to scale hydrogen while minimizing costs.

Regional Hydrogen Clusters: HyNet and East Coast Cluster

Both clusters repurpose industrial hubs for hydrogen and CCUS deployment, with distinct targets and capacities.

Parameter	HyNet	East Coast Cluster
Location	Liverpool, Manchester	Teesside, Humberside
Hydrogen capacity target (by 2030)	4.5 GW	1 GW (scaling to 5 GW by 2040)
CO2 storage capacity (annual by 2030)	10 million tonnes	27 million tonnes
Key industrial partners	CF Fertilisers, Essar Oil UK, Pilkington Glass	BP, Equinor, SSE Thermal, British Steel, Sabic
Regional emissions reduction target by 2030	25%	50%

CCUS Integration: A Critical Enabler

Both clusters rely on shared CO2 transport and storage networks to reduce costs and improve efficiency. HyNet captures over 90% of CO2 emissions from steam methane reforming and stores captured CO2 offshore in depleted gas fields in Liverpool Bay. The East Coast Cluster links Teesside and Humberside via pipelines to North Sea storage sites, minimizing infrastructure duplication.

• HyNet CO2 pipeline network connects multiple industrial sites to offshore storage
• East Coast Cluster unified CCUS backbone integrates two industrial regions
• Shared infrastructure lowers cost per tonne of CO2 stored

Industrial Applications and Decarbonization Pathways

Hydrogen is used to replace natural gas in high-temperature industrial processes, as a fuel for steelmaking, and as a chemical feedstock. Specific applications include:

1. Steelmaking: Hydrogen-based direct reduced iron (DRI) technology at British Steel’s Scunthorpe plant, potentially cutting emissions by 80%
2. Chemicals: Hydrogen as feedstock for ammonia and methanol production, reducing reliance on fossil-derived inputs
3. Refining and cement: Substitution of fossil fuels in process heat and reactions

Policy Support and Funding Mechanisms

The UK government provides support through the Industrial Decarbonisation Challenge and the CCS Infrastructure Fund. HyNet and the East Coast Cluster were selected as the first two CCUS-enabled hydrogen hubs under the Ten Point Plan for a Green Industrial Revolution. Policy frameworks include the Low-Carbon Hydrogen Standard, which sets emissions thresholds for hydrogen production.

• Funding accelerates development with operational targets by mid-2020s
• Government backing reduces investment risk for infrastructure
• Standard ensures cluster projects meet stringent decarbonization criteria

Challenges and Scalability

Scaling hydrogen and CCUS infrastructure requires significant capital investment. Industrial users must commit to long-term offtake agreements to justify production capacity. The cluster model mitigates these risks by aggregating demand across multiple users, creating a more stable market. HyNet’s phased rollout allows incremental expansion based on actual industrial demand, reducing financial exposure.

Future Outlook and Broader Implications

The HyNet and East Coast Cluster projects will serve as blueprints for additional hydrogen hubs, such as the Scottish Cluster centered around Aberdeen. Emphasis on industrial decarbonization and CCUS integration ensures that hydrogen adoption targets hardest-to-abate sectors first. Lessons learned will inform global efforts, as the UK’s cluster approach demonstrates feasible large-scale hydrogen economies with measurable emission reductions.
