Biomethane

Biomethane is produced from organic matter through anaerobic digestion. This process not only captures methane emissions from waste but also converts them into a usable energy source. Unlike other renewables, biomethane can be directly injected into the natural gas grid, providing a versatile and continuous energy supply.

At Centrica Energy, we offer biomethane solutions that align with global standards, ensuring transparency and reliability. Interestingly, the carbon intensity (CI) of biomethane can sometimes be negative. This is because the process prevents methane, a potent greenhouse gas, from being released into the atmosphere, thus making biomethane a carbon-negative fuel in some cases.

Shortages in natural gas supplies to Europe have highlighted the role of biomethane as an important contributor to gas security of supply, and as greater shares of renewables continue to enter the grid, biomethane will play its role as a key provider of both baseload generation and flexibility as well as an alternative renewable fuel for hard-to-abate industries.

Beyond pioneering in the renewables and energy trading space, Denmark is also a global leader on injection of sustainable biomethane in the gas grid to replace natural gas. Just within the last few years, significant progress has been made in this field, with the share of biogas in the Danish gas grid rising from 17% in December 2020 to +40% in July 2025. This growth underscores Denmark's continued push towards renewable energy, aiming for 100% biogas coverage in the gas grid by 2030.
