natural gas The Troll A natural gas production platform in the North Sea, 80 km (50 miles) northwest of Bergen, Norway. Troll A, the largest movable structure ever built, rests on the seafloor some 300 metres (990 feet) below the surface and rises more than 100 metres (330 feet) above the sea. The platform regulates the recovery of gas from 40 wells located on the seafloor.

Extracting methane hydrates requires extreme caution because these deposits are located in highly sensitive polar ecosystems and marine ecosystems.1

Methane hydrates are unique molecular structures where methane is trapped within icy, cagelike lattices of water. Because these structures rely on very specific, delicate combinations of pressure and temperature to remain stable, any extraction technology must be carefully designed to avoid disrupting the surrounding environment.1

The potential for environmental impact is significant, as these reserves are found beneath permafrost in polar regions and within the ocean bed along continental shelves. Furthermore, methane is a potent greenhouse gas. Because human activities are already increasing atmospheric methane concentrations faster than natural sinks can offset them, any accidental release during extraction could exacerbate the greenhouse effect and contribute to climate change. Consequently, researchers are currently exploring methods to ensure that any future extraction is both economically viable and environmentally sustainable.123
