HA NOI – Twenty seven regions in the country's sea might be home to large gas hydrate reserves, according to recent research by the Ministry of Natural Resources and Environment's Department of Sea and Islands
The possible reserves are spread over a total area of 270sq.km.
The discovery is important since gas hydrate is considered an alternative energy source to coal and petrol. It is even listed by world researchers as one of the nine clean energy resources for the future.
The areas of great potential reserves include the Tri Ton and Phu Khanh islands and the south western part of the East Sea.
Research on seabed terrain has revealed various anomalous signals that show the possible existence of gas hydrate; for instance the sudden change of terrain from several hundreds meters deep to 2,000km deep and the features of underground volcanoes and plateaus.
Temperatures in the East Sea under 300m in depth is also said to be suitable to gas formation.
Gas hydrate is a crystalline solid; its building blocks consist of a gas molecule surrounded by a cage of water molecules. – VNS
