The oil shock raises a hard question: can China turn its vast coal reserves into a lifeline for countries facing disrupted fuel supplies? Its expanding coal-to-oil industry offers one possible answer- but not a quick fix.
The International Energy Agency (IEA) said in its October 2026 report that global oil inventories were 509 million barrels below their end-February level. It forecast world oil demand to fall by 2.6 million barrels a day in 2026 as war-related disruption and high prices hit consumption.
China has coal and the technology
But China’s coal output rose slightly by 1.4 per cent in 2025 to 4.85 billion tonnes, according to the National Bureau of Statistics. This provides it with a large asset base and experience in coal power and chemicals.
Coal has the potential to produce more than electricity. It can be converted to synthetic fuels, such as diesel fuels, using coal-to-liquids technology. According to the IEA, in 2022 China consumed approximately 40 million tonnes of coal for the production of approximately 11 million tonnes of oil products. A recent report has revealed that a large plant in Ningxia burned 24 million tonnes of coal in 2025. The numbers indicate that the technology is in use at scale.
Coal chemistry can also provide a source of methanol and ammonia for producing fertiliser. This may alleviate the situation of industries needing chemicals. However, coal-fired electricity isn’t a direct replacement for petrol, diesel or jet fuel powering transport.
Why coal cannot replace oil overnight
The most difficult aspect is scaling. Plants, investment, water and time are required for coal to be converted to liquid fuels. Existing capacity is not available to make up a big shortfall in the world market in the blink of an eye, and synthetic products might require additional processing.
There’s an ecology price tag, too. Studies on the coal industry in China point to the need for greater water consumption and a higher level of carbon emissions than with standard oil travel. The availability of water in many water-rich regions in northern and western China is already limited, which makes expansion more challenging.
A buffer, not a silver bullet
Coal supplies from China might become available at a time of extended oil shock, and manufacturing power might be available for energy projects outside the country. How much relief it can offer will be determined by exports, costs, infrastructure and environmental constraints.
It’s not as if coal can save the world. There are several options for energy security: emergency stocks, reliable trade, cleaner power, renewables and more efficient fuel use. China’s coal technology will give it some time, but it won’t eradicate the risks of an oil-dominated world.
