Tan Deku, a manager from CNPC’s Liaohe Oilfield, said that the peak daily gas extraction can meet the demands of 30 million households. Since the first round of gas extraction in 2016, the gas storage group in Liaohe has extracted 5 billion cubic meters of gas, reducing carbon dioxide emissions by 4.353 million tons, compared with coal of the same combustion value.
The expansion project has strategic significance in adjusting China's energy structure, and promoting energy conservation and greenhouse gas emissions reduction, in order to cope with climate change, as well as ensuring gas supply security and national strategic reserves, analyst said.
In 2035, the project is expected to consist of the largest underground gas storage group in China, with a peaking capacity of 10 billion cubic meters.
