This project explored a new way to produce methanol—a useful fuel and chemical—using waste gases from renewable sources. Methanol is widely used in fuels and the chemical industry, but the UK relies heavily on imports. The aim was to create a local, sustainable method of producing methanol using carbon dioxide from biogas and hydrogen from wind energy.
Researchers from Queen’s University Belfast worked with three industry partners to design and test a small-scale pilot system. This system used carbon dioxide captured from anaerobic digestion plants and hydrogen generated from excess wind power. The gases were combined in a specially designed reactor to produce methanol. The team also developed new catalysts to improve the efficiency and purity of the methanol produced.
The project showed promising results. One of the new catalysts achieved better conversion rates and higher methanol selectivity compared to existing commercial options. The team also explored ways to make the process more stable and scalable.
If developed further, this approach could help Northern Ireland reduce its carbon emissions and create new economic opportunities. Methanol production from local waste sources could support energy independence, reduce reliance on imports, and open up new business models for rural communities. The project laid the groundwork for future investment and larger-scale production, with the potential to attract commercial partners and contribute to a greener economy.
