Water-derived adsorbed species are shown to be critical for methanol production under reaction conditions over copper catalysts - a fact not included in prior microkinetic models.  New mechanistic simulations provide a likely alternative that both precludes the direct hydrogenation of adsorbed formate, and accounts for the observed effects of water.
