Coal is not vanishing from China's economy, it is simply moving to a different address. While coal fired electricity generation fell by 113 TWh in 2025 to 6,294 TWh, the country still burned through roughly 440 million tonnes of coal per month in December, and record volumes of the fuel are now flowing into synthetic fuel and chemical plants rather than power stations.
At a Glance
- China's electricity demand rose 5% between 2024 and 2025 to 10,368 TWh, with nuclear and renewables absorbing the entire increase (up a combined 617 TWh).
- Coal fired generation dropped 113 TWh even as China approved or revived 161 GW of new coal power projects in 2025, a record, with 291 GW more under construction.
- Coal to liquids and coal to chemicals plants now consume about 380 million tonnes of coal a year, according to the IEA, with roughly 80% of ammonia and methanol output now coal fed.
- Domestic coal inventories fell from 25 million tonnes to about 18 million tonnes in the second half of 2025, while imports eased to 373.5 million tonnes from 2024's record 427 million tonnes.
- Coal in Qinhuangdao trades near $105 to $110 a tonne, against a Brent crude equivalent of roughly $525 a tonne at $71 a barrel, a gap that keeps synthetic fuel economics attractive.
Why Renewables Are Winning the Power Sector
The cost curve tells most of the story. Utility scale solar's levelized cost has dropped 80% since 2015, from $115 per megawatt hour to $30, while wind has fallen three quarters, from $90 to $25. Renewable generation has grown more than tenfold over the same stretch, and nuclear capacity climbed from 27 GW in 2015 to 62 GW by early 2026. Those numbers alone would make coal a tougher sell in the power market, but China also solved a logistics problem. Most of its wind and solar sits in remote western provinces like Inner Mongolia, Xinjiang and Gansu, far from the industrial coast. Roughly 340 GW of ultrahigh voltage transmission lines now move that power east, removing what had been a hard ceiling on renewable growth.
None of this means Beijing is walking away from coal plants themselves. Instead, coal capacity is being repositioned as backup muscle for the grid, insurance against drought, weak wind, or fuel disruptions. Those risks are not hypothetical: blackouts hit more than 20 provinces in 2021 and 2022, and a 2022 drought in Sichuan, where hydropower supplies about 80% of electricity, forced shutdowns at plants run by Toyota and Foxconn. That memory helps explain why China approved or revived 161 GW of coal power capacity in 2025, a record, with another 291 GW under construction. As that capacity comes online, utilization at coal plants, already averaging just 51% over five years, could slide toward 40%.
Where the Missing Coal Is Actually Going
Here is the puzzle in the data: if coal fired power is shrinking, why do production, imports and consumption not show a matching decline? China still mined about 440 million tonnes of coal in December alone. Imports slipped to 373.5 million tonnes in 2025 from 2024's record 427 million tonnes, but that is still well above the roughly 260 million tonnes a year typical before 2022. Exports edged down to 13.9 million tonnes, and domestic stockpiles fell hard in the second half of the year, from 25 million tonnes to about 18 million tonnes. Falling inventories alongside falling power sector demand point to one conclusion: coal consumption elsewhere in the economy is not slowing at anywhere near the pace power generation numbers suggest.
The answer sits in coal to liquids and coal to chemicals technology, an industrial process China and South Africa are the only countries running at real scale. Using Fischer Tropsch synthesis, coal gets converted into diesel, gasoline, naphtha and petrochemical building blocks like olefins used in plastics. The IEA puts China's coal use for chemicals and synthetic fuel at 380 million tonnes annually, with the bulk of that flowing into chemicals rather than fuel. Coal has effectively replaced natural gas as the primary feedstock for ammonia and methanol, with about 80% of that chemical output now coal based.
The Economics of Synthetic Fuel
China's flagship facility, the Shenhua Ningxia plant that started up in 2016, turns about 44,000 tonnes of coal a day into roughly 100,000 barrels a day of synthetic fuel. A standard refinery would need only about 14,000 tonnes of crude oil to match that output, but the price gap makes coal competitive anyway. Coal at Qinhuangdao runs $105 to $110 a tonne, while Brent's crude equivalent works out to about $525 a tonne with oil, tracked broadly by the USO ETF, near $71 a barrel. Even after factoring in conversion costs, that spread leaves coal based synthetic fuel with a real economic edge, particularly when oil markets get volatile.
Energy Security and the Political Logic Behind the Shift
China imports a large share of its crude from countries exposed to sanctions or conflict risk, including Iran, Venezuela and Russia. Domestic coal converted into synthetic fuel offers a hedge against supply shocks, shipping chokepoints or sanctions pressure, even though CTL still covers only a modest slice of total fuel demand. There is also a regional employment angle. Most CTL and CTC projects sit in coal rich, economically lagging inland provinces such as Inner Mongolia, Ningxia, Shaanxi and Xinjiang, areas where roughly 3 million people work directly in coal mining and several million more depend on it indirectly. Shifting coal from power plants into chemical and fuel production lets Beijing keep mining output and jobs intact while still showing a cleaner electricity mix in official reporting.
That reporting angle matters more than it might seem. Pulling coal out of the power sector improves the headline decarbonization numbers that show up in environmental disclosures, even though CTL and CTC processes are often more carbon intensive per unit of fuel than conventional refining, and they use heavy volumes of water while producing contaminated wastewater, a particular concern in the water scarce northern provinces where most of these plants operate. Emissions from coal burned for chemicals simply attract far less public attention than emissions from a coal fired power station's smokestack.
Is China's Coal Use Actually Falling?
The honest answer is no, not in aggregate, it is being rerouted. Renewables are outcompeting coal in electricity generation on cost, scale and political optics. But coal itself is being redirected into synthetic fuels and petrochemicals, sectors that let China preserve industrial output, mining jobs and a buffer against energy security risks tied to imported oil. The country's coal story in 2025 is less about retreat and more about repositioning, with the fuel showing up in diesel tanks and plastic pellets even as it fades from the grid.
