China's largest liquefied natural gas (LNG) storage tank, with a storage capacity of 270,000 cubic meters, was put into operation at Sinopec Qingdao LNG Receiving Terminal on Thursday, said its operator China Petroleum & Chemical Corp, also known as Sinopec.

The tank will have an additional gas storage capacity of 165 million cubic meters, which can meet the gas demand of 2.16 million households for five months during the winter, to ensure sufficient gas supply in the country, it said.

The storage capacity of the LNG storage tank, which is designed and constructed by Sinopec, also ranks as one of the top in the world, it said.

On the same day, the second phase of Sinopec Tianjin LNG Receiving Terminal was officially completed, adding more than 400 million cubic meters of gas storage capacity. The company vows to further step up LNG storage tank and receiving terminal construction to ensure sufficient gas supply in the country.
