As the UK explores options to decarbonise domestic heating, biomethane emerges as a controversial yet promising alternative that leverages agricultural waste and existing infrastructure, though its future remains uncertain amid ongoing debates over sustainability and climate impact.
Biomethane is emerging as a quiet but contested option in the UK’s effort to decarbonise home heating, with industry figures arguing that gas made from farm waste could cut bills, reduce imports and make use of existing networks.
Supporters say the case is compelling because biomethane is chemically identical to natural gas, meaning it can be blended into or injected directly into the current gas grid rather than requiring households to rip out boilers overnight. That matters in a country still heavily dependent on gas for heating, where around 25 million homes remain on the network.
Future Energy Networks, the trade body for gas networks, says the UK already has enough production capacity to heat about one million homes, even though only a small share of available organic farm waste is currently being used. The group argues that a larger biomethane industry could eventually supply more than two thirds of Britain’s gas demand by 2050, while cutting dependence on imported gas and easing exposure to global price shocks.
The policy push comes as ministers continue to back heat pumps as the main route away from fossil-fuel heating. Biomethane advocates say that leaves too little room in the debate for a fuel that can use existing pipes and appliances, while also offering an outlet for manure, slurry, food waste and other organic residues from farms and food systems. SGN, one of the gas network operators, says the fuel is renewable and still far from fully exploited, with just 2.5 per cent of available organic farm waste being used.
The industry also argues that biomethane could support rural investment and strengthen energy security. James Earl, chief executive of Future Energy Networks, said the fuel could be deployed quickly where there is local demand and would bring jobs and capital into countryside communities. Chris Huhne, former energy secretary and now chair of the Anaerobic Digestion and Bioresources Association, has also backed a larger role for the sector, saying it can be stored, dispatched when needed and delivered through infrastructure the UK already has.
But the case is not universally accepted. Green Alliance has warned that a growing share of feedstock can come from purpose-grown crops rather than genuine waste, raising land-use concerns, while methane leakage during production and transport remains a climate risk. The MCS Foundation, which favours heat pumps over gas-based solutions, has gone further, arguing in research that biomethane could meet only a limited share of UK gas demand by 2050 and is not a realistic substitute for widespread home heating.
That leaves biomethane in a middle ground: useful, but contested. It is already being used in the UK, including at major plants such as Apsley Farms’ facility, which has been supplying renewable gas to the grid for years, but the sector’s future depends heavily on policy. The Department for Energy Security and Net Zero says producers can apply for support through the Green Gas Support Scheme, while a consultation is under way on how biomethane should be treated under the UK emissions trading system.
For industrial decarbonisation professionals, the real question is not whether biomethane matters, but how far it can scale without competing with other land, waste and climate priorities. Its advocates see a homegrown bridge fuel; its critics see a useful niche rather than a system-wide answer.

- https://www.sgn.co.uk/about-us/future-of-gas/biomethane – Biomethane is a renewable gas produced from organic materials like food waste, manure, and sewage. It is chemically identical to natural gas and can be used for heating and cooking. Currently, only 2.5% of the UK’s available organic farm waste is utilised to create biomethane, indicating significant untapped potential. Increasing its distribution is a key component of SGN’s strategy to reduce carbon emissions and move towards a net-zero future.
- https://www.agrirs.co.uk/key-terms/biomethane – Biomethane is a renewable gas produced by upgrading biogas to remove carbon dioxide, water vapour, and impurities, resulting in a high-purity methane fuel chemically similar to natural gas. It is typically generated from agricultural feedstocks such as manure, slurry, crop residues, and food waste through anaerobic digestion, before being refined to grid-quality standards. Biomethane plays a central role in decarbonising rural energy systems and supporting Net Zero farming strategies.
- https://www.theguardian.com/environment/2025/sep/30/biomethane-not-viable-for-widespread-use-in-uk-home-heating-report-finds – A study by the MCS Foundation found that biomethane could account for only up to 18% of the UK’s current gas demand by 2050. The research suggests that while biomethane has a role in decarbonising certain sectors, it is not a viable alternative for widespread home heating. The study advocates for a focus on heat pumps as the primary solution for decarbonising domestic heating.
- https://www.apsleyfarms.com/biomethane/ – Apsley Farms operates the UK’s third-largest biomethane plant, supplying renewable natural gas to the UK gas grid since 2014. The facility processes plant material obtained from their own and neighbouring farms, producing biomethane with a carbon footprint approximately one-fifth that of natural gas. This sustainable fuel contributes to meeting the UK’s energy needs and climate targets.
- https://www.goodenergy.co.uk/our-energy/green-gas/ – Good Energy supplies gas produced from organic matter such as leftover food and agricultural waste, processed in anaerobic digesters to produce methane gas. This biogas is then injected into the gas grid and used in the same way as natural gas for heating and cooking. Good Energy supplies 10% biogas, representing the maximum percentage of the UK’s gas demand that can be met from sustainably produced, UK-generated biogas.

The taskforce aims to promote the key role of green gases in the energy sector’s net-zero transition while boosting energy security and driving growth. They believe that biomethane has far greater potential to decarbonise the energy system than is currently being realised and can be readily scaled up.
