Domestic NG(billion m3) imported LNG
imported pipeline NG Consumption Growth Rate
Domestic NG Production Rate
LNG imports growth trend will continue, but
growth rate may get slow, since
Natural gas accounts for only 7.8%.
Consumption VS production growth rate.
Government's Environmental Policy.
LNG Seasonal peak-shaving role.
Challenges faced by LNG domestic market
LNG fueling face competition from
electric vehicles.
Import LNG lacks competitiveness.
Chinese LNG facilities
1. Current situation of Chinese LNG industry
Current LNG facilities
20 LNG receiving terminals in operation with total capacity
of 71.25MTPA. 7 terminals in construction.
190 small LNG plants(<1MTPA) in operation, with total
capacity of 27MTPA.
2528 LNG fueling stations, 310,000 LNG vehicles.
280 LNG power ships and 18 inland LNG filling wharfs have
been built. 4 LNG power coastal tugs in operation.
