US Scientists have revealed how natural gas locked up in frozen water crystals could provide massive amounts of energy, and claim that it could even be totally emissions-free.

The astonishing claim was made by Tim Collett of the United States Geological Survey at last weeks national meeting of the American Chemical Society. Collett told the gathering that, to the naked eye, clathrate hydrate (CH) looks like everyday ice but, as well as being partly made of water, the molecules are also organised into “cages”, which trap individual molecules of methane.

Remarkably, a new method of extracting the methane and ’swapping’ it with carbon dioxide could turn the substance into a revolutionary carbon-neutral fossil fuel.
