Has flown radio controlled plane using 'sea fuel' in first test of new fuel
New technique can capture 92% of CO2 in water to create jet fuel
Could be used to create fuel for any vehicle without having to modify engines
The NRL process begins by extracting carbon dioxide and hydrogen from seawater.
As seawater passes through a sepcially built cell, it is subjected to a small electric current.
This causes the seawater to exchange hydrogen ions produced at the anode with sodium ions.
As a result, the seawater is acidified.
Meanwhile, at the cathode, the water is reduced to hydrogen gas and sodium hydroxide is formed.
The end product is hydrogen and carbon dioxide gas, and the sodium hydroxide is added to the leftover seawater to neutralize its acidity.
In the next step, the hydrogen and carbon dioxide are passed into a heated reaction chamber with an iron catalyst.
The gases combine and form long-chained unsaturated hydrocarbons with methane as a by-product.
The unsaturated hydrocarbons are then made to form longer hydrocarbon molecules containing six to nine carbon atoms.
Using a nickel-supported catalyst, these are then converted into jet fuel.
