LNG Gasification Energy Recovery With Integrated Cold Storage

The patent combines multiple previously separate systems (negative energy recovery, power generation, and energy storage) into a single integrated LNG system. The gasification device, heat exchangers, turbines, and energy storage tanks work together as a unified system, allowing simultaneous recovery of negative energy, generation of power, and storage of energy, thereby dramatically improving heat-absorbing utilization efficiency while managing system complexity through functional integration

The integrated system performs multiple functions simultaneously: the gasification device not only vaporizes LNG but also recovers negative energy; the heat exchangers transfer heat for both power generation and energy storage; the turbines generate electricity from multiple heat sources. This multi-functionality allows the system to maximize energy utilization from LNG while maintaining a coordinated structure that manages complexity through shared components

The patent converts waste heat, which was previously a harmful loss, into a beneficial resource for power generation. The heat exchangers capture waste heat from the gasification process and transfer it to turbines, which generate electricity. This transforms the harmful waste heat into useful energy, reducing energy loss while the systematic integration of heat utilization components manages the complexity through coordinated heat transfer pathways

The system recovers energy that would otherwise be discarded as waste heat. The heat exchangers intercept heat from the LNG gasification process before it is lost, and transfer it to the power generation subsystem. This recovery process converts previously discarded thermal energy into electrical power, reducing energy loss while the integrated structure manages complexity by systematically routing heat through multiple utilization pathways
