Systems and methods are provided for conversion of renewable power into hydrocarbons, such as hydrocarbon fuels, via a methanol intermediate. In addition, it is desired to capture and reuse carbon dioxide in order to form these hydrocarbons. When the conversion of carbon dioxide is performed using hydrogen generated by electrolysis (preferably from renewable electricity), the management of process water is beneficial for reducing or minimizing the overall water requirements for the process as well as extending the lifetime of the electrolyzers. Systems and methods are also provided for recovery and purification of process water for recycle to the electrolyzers.
