Research progress in LNG cold energy utilization technology
The utilization of liquefied natural gas(LNG)cold energy supports the low-carbon transformation and healthy growth of China's cold industry.This paper summarizes the typical research results on using LNG cold energy in power generation,air separation,liquid carbon dioxide and dry ice preparation,cooling and ice production,freezing desalination of seawater,food cold processing and cascaded utilization and other technologies,along with their industrial applications.It analyses the challenges of low cold energy utilization rate and the limitation of single-project in operation,and envisions the development of a cold industry cluster with LNG cold energy as the core.This cluster integrates auxiliary energy supply technologies such as Boil Off Gas(BOG)combustion power generation,electric-driven compression refrigeration,energy storage,and photovoltaic power generation and integrated energy supply stations to foster multi-energy complementarity,energy storage load balancing,intelligent control,and comprehensive energy supply,encouraging the collaborative growth of distributed industries.
