In 2008, Oxford researchers described a laboratory process intended to turn glycerol, a biodiesel by-product, directly into methanol using catalytic hydrogenolysis. It aimed to avoid making synthesis gas first, but the report said the process had only been demonstrated in the lab. A patent also records a later analytical caveat that weakens the early claim of methanol selectivity.
What was the proposed cleaner route?
The route reported by James Urquhart in Chemistry World on 5 November 2008 began with glycerol, a by-product of biodiesel production. Researchers at Oxford proposed converting it directly into methanol through catalytic hydrogenolysis, rather than first turning the feedstock into synthesis gas (syngas) and then making methanol from that gas.

The idea addressed two connected issues raised in the report: methanol was largely made from natural gas, while surplus glycerol could be difficult to use. The article attributed to the period the claim that around 90% of world methanol production came from natural gas; it did not give a separate statistical source or reference year, so that figure should not be read as a current estimate. Edman Tsang, the research lead, also cited around 350,000 tonnes of glycerol incinerated annually in the US. The report did not specify the year or underlying source for that historical estimate.

How did the laboratory process work?
The 2008 report describes glycerol reacting with hydrogen over a supported precious-metal catalyst. It gives reaction conditions of 100°C and 20 bar of hydrogen. The intended chemistry broke glycerol’s carbon–carbon bonds while avoiding carbon–oxygen bond cleavage, which could produce gases such as methane and carbon dioxide. The article did not identify the catalyst.
#1 Best Overall
The proposed advantage was a shorter process route: direct conversion of glycerol instead of a separate syngas-production stage followed by methanol synthesis. Fewer steps are an attractive process concept, but by themselves they do not establish higher overall efficiency, lower emissions, better economics, or suitability for industrial operation.
Was the process scaled up?
No scale-up is established by the 2008 report. It states explicitly: “So far the technique has only been demonstrated in the laboratory.” The article quoted Jamie Ferguson, project manager at Isis Innovation, saying, “Such catalytic processes have proved to be scaleable in the past.” That was a contemporaneous view about potential, not evidence that this particular process was subsequently scaled or commercialized.
Rank #2
The available sources do not verify commercial deployment of the Oxford process. A laboratory result and a general expectation that catalytic processes can scale are not substitutes for a demonstrated pilot or industrial plant.

The patent application describes a methanol-production process based on hydrogenolysis of sugar alcohols, including glycerol. Its experimental section adds an important qualification: initial results claiming methanol as the exclusive product could not be replicated in later tests using an improved analytical method that captured both gas and liquid products. That caveat matters because product selectivity is central to judging whether the conversion works as claimed and what separation or coproduct handling might be required.
The patent record does not, on its own, establish the eventual performance, economics, or deployment status of the Oxford process. It does mean that the early exclusive-methanol result should not be presented as a settled, independently confirmed outcome.
How does this compare with later glycerol research?
A later study titled “Efficient green methanol synthesis from glycerol” describes a distinct route: crude glycerol is converted with water over basic or redox oxide catalysts at low pressure, producing methanol together with other useful chemicals. It should not be conflated with the 2008 Oxford route, which the report describes as hydrogenolysis over a supported precious-metal catalyst at 20 bar hydrogen.
Comparing glycerol-conversion claims requires more than checking whether methanol appears among the products. Relevant differences include whether the feed is crude or purified glycerol, catalyst family, hydrogen source and pressure, temperature, product selectivity and coproducts, how completely gas and liquid products were measured, and the demonstrated scale. The later study is evidence of related research, not proof that the Oxford process advanced to commercial use.

The title phrase refers to the proposed use of a biodiesel by-product and the possibility of bypassing a syngas intermediate; it does not establish a measured lifecycle-emissions advantage. A full environmental comparison would need to account for the glycerol’s origin and treatment, hydrogen production, process energy, coproducts, separation, and the chosen system boundary.
Best Value
For context, a 2026 review of methanol production from biomass and waste gasification highlights gas-cleaning requirements because syngas impurities can constrain process design. That is relevant background on an alternative renewable pathway, not evidence about the Oxford route’s scale-up or environmental performance. The review also reports approximate selling-price ranges of 100–300 €/t for fossil methanol, 350–1,050 €/t for biomethanol, and 500–950 €/t for e-methanol. These are review-reported estimates, not live market prices or a cost estimate for methanol made by the Oxford process.
What did the researchers say about methanol’s value?
Tsang told Chemistry World: “Methanol is undoubtedly one of the key chemicals in our present chemical industry with a huge potential as a source of renewable energy and also a building block for the production of other chemicals.” That explains the interest in alternative feedstocks, but the promise of methanol as a chemical or energy carrier does not establish the performance of any particular production route.
