Methane hydrate is a solid compound made of water and methane, where methane molecules are trapped within a lattice of ice. It typically forms in ocean sediments and permafrost under high pressure and low temperature conditions. Methane hydrate is considered a potential energy resource, as it contains a large amount of methane, which can be used as a fuel. When methane hydrate is heated or depressurized, it can release methane gas. This process raises concerns about climate change, as methane is a potent greenhouse gas. Understanding and managing methane hydrate is crucial for both energy production and environmental protection.
