The company, Air Fuel Syndication, then uses the carbon dioxide and hydrogen to produce methanol which in turn is passed through a gasoline fuel reactor, creating petrol.

The mice's consumption of oxygen and production of carbon dioxide dropped ten minutes after they began inhaling hydrogen sulphide and remained extremely low as long as the gas was administered.

This gas contains approximately 80% of the original energy content of the coal, and is a combination of hydrogen, carbon monoxide, carbon dioxide, and methane.

The idea is that it would be fed hydrogen and carbon dioxide, derived, perhaps, from natural gas, which has been discovered in great quantities in the U.S. and elsewhere recently.

That's just 10% what the plant emits, but Jones argues Skyonic should get credit for avoiding 220, 000 tons of carbon dioxide because it is creating products, like hydrogen, that would otherwise come from natural gas and release lots of carbon dioxide.

The highly toxic H2S (hydrogen sulfide) and CO2 (carbon dioxide) are removed along with excess water to get the gas below 7 ppm (parts per million).

FutureGen would be a near zero-emissions plant that converted coal into hydrogen, to power electric turbines, and carbon dioxide, to be pumped underground.

The 275-megawatt demonstration plant is designed to prove the feasibility of producing electricity and hydrogen from coal, while simultaneously capturing the carbon dioxide and sequestering it in deep underground reservoirs.

The gas is then fed into a stack of solid oxide fuel cells, where a chemical reaction between hydrogen and oxygen occurs, producing electricity, water vapor and a tiny amount of carbon dioxide.

Carbon dioxide, blamed for global warming, is produced when fuels like coal and natural gas are broken down to make the hydrogen used in fuel cells.
