The Navy Is Trying To Turn Water Into Fuel
A hazardous work environment, a less than stellar relationship with the Middle East, and soaring gas prices has created a requirement to make fuel out of water. Take a look into the Navy's answer for refueling at sea in the future.
From the Navy's Naval Research Laboratory:
NRL has developed a two-step process in the laboratory to convert the CO2 and H2 gathered from the seawater to liquid hydrocarbons. In the first step, an iron-based catalyst has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production from 97 percent to 25 percent in favor of longer-chain unsaturated hydrocarbons (olefins).
