At present, the LNG cold energy power generation technology is relatively mature, if cold energy generated by LNG gasification is completely converted into electric energy, each ton of LNG can generate about 240KWh of energy, the annual import quantity of the LNG in China in 2017 is 3593 ten thousand tons, and if the cold energy is completely utilized for power generation, the KWh is 86.2 hundred million. It can be seen that the electric quantity contained in the electric energy is so large that if the electric energy is fully utilized, a lot of resources can be saved.

However, the cold energy power generation of the small-sized LNG vaporizer has its own advantages, such as short pipeline transportation distance, no need of large investment and maintenance of underground pipelines, and low vaporization pressure, and the utilization of the cold energy has a relatively high economic value.
However, if a construction mode of large-scale LNG cold energy power generation is adopted to generate power by using the cold energy of the small-scale LNG vaporizer, not only is the project investment large, but also the long-term stable operation of the power generation system throughout the year is difficult to guarantee, and the economic benefit of the system is difficult to guarantee.
In order to effectively utilize the cold energy of the LNG, the problem of downstream industrial chain matching needs to be considered in the planning and construction of an LNG receiving station, but the problem that the small-sized gasification station is difficult to be matched with the downstream due to the restrictions of geographical position, scale and the like is solved. Compared with the cold load supply, cold energy power generation is a mode with a shorter downstream industrial chain, the electricity is very wide in application range and convenient to consume on site, and the load of a power grid can be relieved after grid connection.
