Methane-munching microorganisms meddle with metals

On the continental margins, where the seafloor drops hundreds of meters below the water's surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential ...

Arctic gas hydrate: Vast energy resource or climate threat?

Arctic gas hydrate is a fossil resource mainly consisting of methane. It may represent a larger energy supply than all other oil and gas resources put together. But what is the potential impact of gas hydrate on climate change ...

Japan extracts 'fire ice' gas from seabed

Japan said Tuesday it had successfully extracted methane hydrate, known as "fire ice", from its seabed, possibly unlocking many years' worth of gas for the resource-starved country.

New tool for measuring frozen gas in ocean floor sediments

A collaboration between the National Oceanography Centre (NOC) and the University of Southampton is to develop an instrument capable of simulating the high pressures and low temperatures needed to create hydrate in sediment ...

The great gas hydrate escape

For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis of the ice and gas compound, known as a gas hydrate, reveals key details ...
