The report highlighted growing efforts to cut emissions along the gas value chain. Operators are electrifying processes, improving leak detection and expanding carbon-capture and storage (CCUS). Biomethane production, described as the most promising low-carbon gas, reached 9.6 bcm in 2024 – seven times the level a decade earlier – supported by European feed-in tariffs and premiums. Global output is projected to rise 14% annually through 2040, driven by targets in Europe and China. CCUS capacity is also climbing, with major projects reaching final investment decision or start-up this year. 

Global unrisked carbon-capture capacity is expected to hit 79 mn tonnes per year in 2025 and could rise  more than sevenfold to 577 mn tonnes by 2030, though most planned projects remain in early stages. “[Accelerating progress requires] clearer regulatory frameworks, streamlined permitting and more mature carbon markets,” the IGU said. Clean-hydrogen development has lagged expectations because of inflation and weak demand from potential buyers, discouraging new projects. The report said stronger policy support and long-term offtake agreements are needed to build market confidence and attract investment. Governments can spur low-carbon gas adoption by guaranteeing long-term purchases to give producers revenue certainty, the IGU added. Policies such as book-and-claim systems for biomethane, contracts for difference for CCUS, and auctions for hydrogen offtake can help secure f inancing and speed commercial rollout.
