Fuel from Seawater?
Researchers at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, have been able to produce liquid hydrocarbon fuel from hydrogen and carbon dioxide extracted from seawater. Using their own proprietary electrolytic process, the research team were able to extract dissolved CO2 and H2 from carbonates in the seawater. These gases were then recombined in their gas-to-liquid process into long-chain hydrocarbons, which they then demonstrated in the off-the-shelf internal combustion engine of a radio-controlled airplane.
With added research, this novel approach to producing fuel from regular seawater may hold some promise for our energy future.
