How a cold energy storage system works?

The energy storage system can release the stored cold energy by power generation or direct cooling when the energy demand increases rapidly. The schematic diagram of the cold energy storage system by using LNG cold energy is shown in Fig. 11.

Which cold energy storage systems can be used for LNG cold energy utilization?

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. Using LNG to cool the compressed air into the liquid air is one route .

How much power does a cold storage system use?

The operation power consumption is about 1/3. However, cold storage only can installed nearby LNG receiving terminal (within 1 km) due to piping cost and cold storage of relatively high-temperature (around 0 °C) is less economical. The system schematics are shown in Fig. 10.

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 .

How is LNG cold energy used in data centers?

The use of emissions by 34,772 t per year. This is because LNG cold conventional cooling systems in data centers. The adoption of LNG cold energy as a cooling the LNG receiving terminal and digital companies. Another recent study by Sermsuk et al. emissions by 83,859 t per year. The exergy efficiency of this approach was (IRR) of 62%.

Can cold energy be used to generate power?

This study explores various techniques for harnessing cold energy to generate power, ranging from simple to complex technologies. It conducts a comparative analysis of promising technologies suitable for converting cold and cryogenic energy into power.
