In 2008, researchers at Oxford reported a laboratory method intended to convert glycerol—a biodiesel by-product—directly into methanol using catalytic hydrogenolysis. It was presented as a way to bypass the conventional syngas intermediate, but the report said the process had only been demonstrated in the laboratory. A patent also records a later problem with the early claim of exclusive methanol production: more complete product analysis did not reproduce it.
How was glycerol supposed to become methanol?
The Oxford proposal used hydrogen and a supported precious-metal catalyst to break glycerol’s carbon–carbon bonds while avoiding carbon–oxygen bond cleavage, which could produce gases such as methane and carbon dioxide. The 2008 Chemistry World report gave reaction conditions of 100°C and 20 bar hydrogen; it did not disclose the catalyst’s identity. Chemistry World, 5 November 2008.
The proposed advantage was a shorter process: rather than first converting glycerol into synthesis gas (syngas) and then synthesizing methanol, the catalyst would convert glycerol toward methanol directly. “Direct” describes the intended route, not proof that the reaction produced only methanol or that it was ready for industrial use.

What did the 2008 report establish—and what did it not?
The report described the work as a laboratory process and explicitly said it had only been demonstrated at that scale. It quoted project manager Jamie Ferguson saying catalytic processes had proved scalable in the past, but that was an opinion about potential, not a scale-up result for this particular process. The sources available here do not establish that the Oxford method reached commercial deployment.
#1 Best Overall
The report framed the work against methanol production then, saying around 90% of world production came from natural gas. That is a period claim reported in 2008, not a current production statistic. It also quoted research lead Edman Tsang estimating that around 350,000 tonnes of glycerol were incinerated annually in the United States. The report did not specify the estimate’s underlying year or source, so it should be treated as a historical attributed figure, not a verified current measurement.
Why is the early selectivity claim uncertain?
A patent application describing methanol production through hydrogenolysis of sugar alcohols, including glycerol, contains an important qualification. Its experimental section says initial results that claimed methanol as the exclusive product could not be replicated in subsequent tests using an improved analytical method that captured both gas and liquid products. US patent application US20090240178A1.
Rank #2
This matters because a product analysis limited to part of the output can miss compounds that leave as gases. The patent caveat does not, by itself, establish that no methanol was produced; it does undermine treating the early exclusive-product result as confirmed. Selectivity claims are meaningful only when the analysis accounts for the full product stream.

A later study titled “Efficient green methanol synthesis from glycerol” describes a distinct approach: converting crude glycerol with water over basic or redox oxide catalysts at low pressure, producing methanol along with other useful chemicals. It should not be treated as a replication or scale-up of the Oxford supported-precious-metal hydrogenolysis route. “Efficient green methanol synthesis from glycerol”.
These approaches are not interchangeable simply because both start with glycerol. A fair comparison needs to account for feedstock quality, catalyst family, hydrogen use and pressure, temperature, coproducts, completeness of product analysis, and demonstrated scale. The later study establishes that related glycerol-to-methanol research exists; it does not establish commercial deployment of the 2008 process.

Glycerol is one possible renewable carbon source, not a guarantee of a cleaner or cheaper final fuel. A meaningful comparison with other methanol pathways depends on the feedstock and carbon source, the energy required, process maturity, and the lifecycle-emissions boundary used. For example, gasification-based routes also face process-design challenges: a 2026 review highlights the need to clean syngas when impurities exceed process limits. That is context about an alternative pathway, not evidence about the Oxford route. Cabrera-Gallardo, Baena-Moreno, Rodríguez-Galán and Vidal-Barrero, 2026 review.
The same review gives approximate selling-price ranges of 100–300 €/t for fossil methanol, 350–1050 €/t for biomethanol, and 500–950 €/t for e-methanol. These are review-reported estimates, not live market prices or a cost estimate for the Oxford glycerol process. They should not be read as directly comparable without the review’s assumptions and the relevant production and lifecycle boundaries.
