In a compelling argument for energy diversification, Chris Huhne, Chair of the Anaerobic Digestion and Bioresources Association, has highlighted that the United Kingdom must not limit itself to a binary choice between expanding North Sea drilling or increasing imports of liquefied natural gas (LNG). Instead, he advocates for a strategic shift towards biomethane, a renewable and homegrown gas source that could significantly enhance the nation's energy security while aligning with climate goals.
The Critical Role of Gas in the UK Energy System
Gas remains an essential component of the UK's energy infrastructure, crucial for heating homes and ensuring power system resilience for the foreseeable future. However, reliance on volatile global markets for LNG exposes the country to price shocks and potential disruptions, as noted by commentators like Nils Pratley. This vulnerability underscores the urgent need for more stable and sustainable alternatives.
Biomethane: A Overlooked Domestic Solution
Biomethane, produced from organic wastes through anaerobic digestion and injected into the existing gas grid, presents a third, often-neglected option. Unlike LNG, which depends on international shipping routes and geopolitical dynamics, biomethane is fully domestic, low carbon, storable, and dispatchable when required. It offers a secure energy source that does not hinge on global uncertainties.
Moreover, unlike new fossil fuel extraction, biomethane supports the UK's climate commitments by reducing greenhouse gas emissions. It also strengthens energy, food, and economic security by utilising waste materials and supporting rural communities and farmers. The International Energy Agency has consistently emphasised the role of green gases in achieving net zero systems, with its 2025 Renewables report identifying biomethane as the fastest-growing renewable if net zero targets are to be met.
International Examples and UK Potential
Within the European Union, countries like Denmark and France demonstrate the viability of scaling up biomethane. Denmark now meets 40% of its gas demand from green gas, while France has seen annual growth exceeding 20% since the Russian invasion of Ukraine in 2022, highlighting its potential for rapid expansion in response to energy crises.
If energy security is the primary objective, the solution lies not merely in producing more fossil gas but in replacing and blending it with green alternatives wherever feasible. Backing biomethane would reduce import dependence, cut emissions, and bolster rural economies, all while leveraging existing infrastructure. The UK possesses the technological and resource capabilities to pursue this path; what is lacking, according to Huhne, is the political will to scale these initiatives effectively.
In summary, prioritising sources of gas that are both homegrown and renewable, such as biomethane, could transform the UK's energy landscape, offering a pragmatic route to enhanced security and sustainability without compromising on environmental or economic fronts.
