"The next major step is to build the infrastructure to convert seawater into fuel on a massive scale. The Navy would first start mass-producing fuel in land-based operations, which would be the first step toward installing fuel generation systems on ships. The Navy predicts the seawater fuel would cost about $3-6 per gallon, and could be commercially viable within a decade."
