China's Coal-to-Gas Capacity Set to Triple by 2030, Threatening LNG Export Markets
Rystad Energy estimates China's synthetic gas output will reach 28 billion cubic metres annually by 2030, a scale that could displace Australian, Qatari and US LNG volumes.
China's coal-to-gas industry is on course to triple its output by 2030, Rystad Energy said in analysis published on August 11 (2026-08-11), as Beijing's 15th Five-Year Plan backs the world's only large-scale commercial program for converting coal into synthetic natural gas.6
Rystad estimates Chinese CTG capacity will reach 9.4 billion cubic metres annually by end of 2026, then grow to 28 Bcm per year by 2030. Around 20 Bcm per year of new CTG capacity is already under active development. JKM, the Asian LNG benchmark, stood at $21.88/MMBtu in the August 18 (2026-08-18) session. Sustained growth in domestic synthetic gas supply, if realised, would reduce China's reliance on purchased spot and term LNG at those prices.4,5,6
Beijing's rationale for CTG is energy security. Supply chains for imported LNG cross geopolitically sensitive sea lanes, and China is building a domestic buffer that can operate independently of international markets. Rystad described CTG as one of "China's many hedges" against supply shocks. No other country has scaled synthetic gas from coal to any meaningful commercial volume.6,4
The LNG market implications flow directly from the scale of the buildout. China is the world's largest LNG buyer, so structural changes in its import appetite ripple through global contract and spot markets alike. Rystad said rising CTG capacity could increasingly influence markets tied to Australian, Qatari and US export projects. Developers of new LNG export capacity financed on long-term Chinese offtake agreements are operating in a market where a domestic substitute is scaling simultaneously.5,4
The CTG expansion sits uneasily with China's parallel low-carbon commitments. The process synthesises gas from coal, sustaining coal combustion at source rather than displacing it. Carbon Brief reported in early June 2026 (2026-06-04) that China's CO2 emissions climbed 2% in the first quarter of the year, partially because wind and solar generation was being curtailed rather than dispatched. The 15th Five-Year Plan wraps CTG inside a low-carbon narrative, but the carbon arithmetic does not straightforwardly support that framing.1
The broader coal picture reinforces the same point. China accounted for 78% of all new coal power generation capacity added globally in 2025, according to OilPrice. As of January 2026, the country still had 206GW of coal-fired capacity under construction, following a year of record additions. China's state oil majors are simultaneously pivoting toward renewables, but the CTG programme and the coal power build together represent a continued large-scale commitment to fossil fuel infrastructure.2,1,3
The 15th Five-Year Plan frames energy security and low-carbon development as parallel rather than competing objectives, and the CTG buildout fits within that construct. Rystad's capacity estimates show the energy security track accelerating sharply. The emissions data, and the scale of the coal power pipeline, suggest the decarbonisation track has yet to gain comparable momentum.6,1
The 20 Bcm of CTG capacity currently under development is the concrete number to test against Rystad's 28 Bcm by 2030 target. If the buildout runs to schedule, the synthetic gas volume would represent a meaningful portion of China's annual LNG import requirement. If it falls short — through project delays, financing constraints or coal supply bottlenecks in production regions — the impact on JKM and spot markets for Australian and Qatari cargoes will be correspondingly limited. China's monthly LNG import data over the next 18 months will be the first indicator of whether CTG is already starting to reshape the demand curve.5,4,6
