Maximising the role of green gas: how hydrogen & biomethane can help to decarbonise the gas network

Case Studies

Britain’s gas networks have launched a collaborative “Maximising the Role of Green Gas” project to explore how biomethane could help deliver quicker reductions in carbon emissions and potential cost savings to customers, and continue to grow as the hydrogen economy develops.

Wales & West Utilities, Cadent, SGN, National Gas and Northern Gas Networks want to understand the challenges and opportunities for biomethane production in the UK and what its development alongside low carbon hydrogen will mean for future network development, technology needs and investment. The organisations will be collaborating under ENA’s Gas Goes Green programme, as formally announced at ADBA‘s recent conference in London.

There are currently 110 plants across the UK with capacity to produce enough biomethane to heat over 770,000 homes each year, saving around 1.2m tonnes of carbon in 2022. The sector has potential to grow further, alongside the development of low carbon hydrogen, which will need to work together to maximise the role green gasses can play in delivery net zero.

Wales & West Utilities Head of Net Zero and Sustainability, Matt Hindle, who is leading the project said:

“Homes, industries, transport and power generation all rely on the gas networks today and need solutions to help them meet net zero.

“The UK has one of the world’s leading biomethane sectors, with over 100 sites injecting green gas into our networks, and an ambitious government strategy for low carbon hydrogen. As gas networks, we need to ensure that biomethane and hydrogen can work together seamlessly in the 284,000 km of pipelines we operate across Britain.

“Repurposing these networks for use with green gases like hydrogen and biomethane to help meet the challenge of the climate change act has the potential to reduce costs and with minimise gas customer disruption to gas customers compared to alternative decarbonisation solutions”

The final report, which is being delivered in partnership with ARUP, will document interactions between biomethane and hydrogen production; options for biomethane sites to produce hydrogen and hydrogen to support biomethane production; and consider the implications for the energy system.
