Tokyo Gas unveils world’s largest underground liquefied natural gas storage tank
Tokyo Gas has unveiled the world’s largest underground liquefied natural gas storage tank to media. In Japan, demand for the resource has been rising as most of the country’s nuclear power stations were shut down after the 2011 disaster. Tokyo gas began building the tank four years ago in Yokohama City, near Tokyo. The underground liquefied natural gas storage tank measures 72 meters in diameter and is nearly 62 meters deep. The tank can store up to 250,000 kiloliters, enough to meet the average annual needs of about 360,000 households.
To prevent leaks, the tank’s interior is covered by 2-millimeter-thick stainless steel plates. The tank could also be used to store shale gas. Tokyo gas plans to start using the tank in November after its completion in July.
