6 FAQs about [Cold energy storage power generation]
Which cold energy storage system can be used for LNG cold energy utilization?
The schematic diagram of the cold energy storage system by using LNG cold energy is shown in Fig. 11. The conventional cold energy storage systems which can be used for LNG cold energy utilization include liquid air system, liquid carbon dioxide system, and phase change material (PCM) system.
How to use LNG cold energy in power generation?
Several utilization ways of how to use LNG cold energy in power generation are discussed. Among them, LNG and gas turbine combined with CO 2 recovery cycle is recommeded. It is comprehensive usage of LNG cold energy recovery, power generation and carbon dioxide emission reduction.
How can a cold energy recovery system be used?
The researchers found that an ORC system, which converts low-temperature heat into electricity, is the most promising technique for recovering cold energy compared to other different kinds of power generation technologies.
What is a cold energy extraction system?
Cold energy extraction system is installed between pump and re-gasification systems or is replaced later one entirely. Representative examples are air separation, power generation, liquid CO 2 production, cold storage and district cooling. Country-specific installation details are shown in Table 2.
What are the basic cryogenic power generation cycles utilizing LNG cold energy?
The basic cryogenic power generation cycles utilizing LNG cold energy are direct expansion cycle, organic Rankine cycle, and Brayton cycle. Among these cycles, direct expansion cycle is a special one since it only utilizes the mechanical exergy (pressure exergy) of LNG .
Can LNG cold energy be stored?
The cold energy of LNG cannot be stored since LNG regasification is a continuous process , and hence must be transferred into an appropriate form of storage. It would be ideal to convert LNG cold energy into other types of cold energy that can be kept frozen for a long time.
