Methane hydrate test well shows promising results

Methane hydrate, often called 'ice that burns', is a crystalline structure of frozen water containing methane molecules. It holds a significant amount of methane, making it a promising natural gas source. Formed under pressure and cold temperatures, methane hydrate is found globally under oceans and permafrost. The US Geological Survey suggests these deposits may exceed all fossil fuels combined. A successful test on Alaska's North Slope involved injecting carbon dioxide and nitrogen to release methane, demonstrating a potential extraction method.
