A method for converting waste water into potable water using power from an electrical grid. The method comprises flowing the waste water through an electrolysis cell coupled to the grid, and, when power availability on the grid is above an upper threshold, biasing the electrolysis cell to form hydrogen. Hydrogen evolved in the electrolysis is then provided as fuel to one or more fuel cells. When the power availability on the grid is below a lower threshold, electric current and potable water are drawn from the one or more fuel cells.
