Progress of LNG Cold Energy Cascade Utilization Research

Liquefied natural gas (LNG), as a clean and efficient form of energy, its cold energy utilisation has been a research hotspot in the energy field. With the adjustment of global energy structure and the enhancement of environmental protection awareness, LNG cold energy cascade utilisation technology has gradually received wide attention. This paper reviews the latest research progress of LNG cold energy cascade utilisation technology, analyses the requirements of different cold energy utilisation units on cold energy quality and the economic benefits of the products, and puts forward directions and suggestions for further research.
