Integrated system (100, Fig. 1) for producing methanol comprising: a gas feed for supplying a methane rich feed gas; and apparatus for converting the methane rich feed gas to methanol. The apparatus comprises an autothermal reformer 206 configured to partially oxidise the methane rich feed gas to maintain the autothermal reformer at a working temperature. The autothermal reformer further comprises electrical heating to maintain the working temperature. Preferably, the electrical energy for the electrical heating is derived from a renewable energy source. The system may comprise an organic waste material digestor (110, Fig. 1) for providing biogas as the methane rich feed gas. The methane rich feed gas may also be natural gas. The system may comprise gas purifying and separating apparatus 204 for removing sulphur components and for separating carbon dioxide. The system may comprise electrolysis apparatus 208 for electrolysing water to provide oxygen and hydrogen feed gases. The system may comprise an agitation tank, bubbler, or continuous flow for adding an additive to the produced methanol in order to constitute a liquid fuel. Also claimed is a method for producing methanol using the integrated system.
