HIIROC Hydrogen to Power (H2P) Project

Centrica’s Brigg Gas Peaker provides flexible electricity during peak demand or low renewable output. In a UK-first trial, low-carbon hydrogen from HiiROC’s pilot plant was blended into the fuel mix, rising from 3% to 20%, to explore hydrogen’s role in power generation. The project is part-funded by the Net Zero Technology Centre. Read the full story here.

Hydrogen Trial Milestone: First Blend into UK’s National Transmission System

Centrica and National Gas successfully trialled a 2% green hydrogen blend in the National Transmission System, powering Brigg Power Station and feeding electricity into the grid. This UK-first proves hydrogen blending is technically and operationally viable, supporting flexible power generation and the UK’s Clean Power goals for 2030. Read the full story here.

Decarbonising lime production at Singleton Birch

This early project for a 10MW electrolyser at the  Melton Ross Quarries to blend hydrogen into the natural gas-fired kilns producing lime, a vital foundation industry key for making batteries, steel, as well as being used in construction, agriculture and wastewater treatment.   The project will allow Centrica to build early skills and project knowledge, key for scale-up. 

Redeveloping Rough Energy Storage

Rough sits in the heart of the Humber.  It currently provides half of the UK’s long duration storage capacity.  Storage will remain key to manage the energy system, increasingly reliant on weather dependent renewables.  Longer term, it is envisaged that Rough could become a more responsive, seasonal storage asset, able to store larger volumes of hydrogen ( Up to 16TWh equivalent - 80,000 grid sized batteries) to meet seasonal energy needs during longer cold, windless spells during winter.

This redevelopment can create over 4,000 transient jobs across the supply chain and a further 100 full-time jobs post-completion.

Humber Hydrogen Pipeline (HHP)

HHP is being developed by Equinor in partnership with both Centrica and SSE to create a network of producers and users across Holderness in East Yorkshire, linked by 45km of dedicated pipelines.  The project links Centrica’s large scale hydrogen production at H2H Easington (with Equinor) to H2H Saltend (Equinor),  including energy generation and key users at the Saltend Chemicals Park, with Aldbrough hydrogen storage and pathfinder project (Equinor and SSE).  Humber Hydrogen Pipeline is a key infrastructure asset to unlock hydrogen cost reductions and drive swift scale up of the system, focused around government’s priority hydrogen users.

The network will include proposals for a Humber crossing and has been designed to enable connection into the wider Project Union & East Coast Hydrogen infrastructure.  It could also work alongside the proposed East Coast Cluster CO2 pipeline to deliver a key regional hydrogen eco-system.
