Gas Hydrates
Gas hydrates are ice-like, solid mixtures of water and small molecules such as methane, making them a potential energy source. The image shows a sample of gas hydrate recovered from the deep ocean seabed offshore Vancouver Island. NRC scientists are pioneers in the study of gas hydrates, and have identified them as a possible way to efficiently store hydrogen gas as a fuel. Only stable under high pressure or at low temperature, they're stored in liquid nitrogen (-196 °C). The cold causes water vapour in the air to condense (see image). |
