Centrica Business Solutions is set to begin injecting hydrogen into its existing gas peaking plant at Brigg, Lincolnshire as part of a UK first trial with HiiROC aimed at better understanding the role of hydrogen in power production.

The 12 month trial will be part funded by a grant from the Net Zero Technology Centre (NZTC), which has given 20 projects a total of £8m through its Open Innovation Programme. Each is aimed at developing technology which could reduce emissions offshore, accelerate clean energy production and enable the delivery of the UK’s net zero ambitions.

The 49MW gas fired plant at Brigg is designed to meet demand during peak times or when generation from renewables is low, typically operating for less than three hours a day. Mixing hydrogen in with natural gas reduces the overall carbon intensity.


It's anticipated that during the trial, getting underway in Q3 2023, no more than three per cent of the gas mix could be hydrogen, increasing to 20% incrementally after the project. Longer term, the vision is to move towards 100% hydrogen and to deploy similar technology across all gas-fired peaking plant.

HiiROC's proprietary technology converts biomethane, flare gas or natural gas into clean hydrogen and carbon black, through an innovative Thermal Plasma Electrolysis process. This results in a low carbon, or potentially negative carbon, 'emerald hydrogen'.

Greg McKenna, Managing Director of Centrica Business Solutions, said: "Gas still plays a huge role in maintaining a secure, stable supply of power in the UK, with around 40 per cent of our power coming from natural gas. So, it’s vital that we find ways to reduce the carbon intensity of gas plants like that at Brigg.

"We're delighted to get the grant funding from the NZTC in order to explore the role of hydrogen in providing the low carbon back-up power we’ll need in order to maintain security of supply as more renewable energy comes on stream."
