TL;DR: In this article, an efficient cryogenic energy storage (CES) process using the exergy from liquefied natural gas (LNG) regasification was developed, where the cold exergy of LNG is transferred in two forms: cold transfer by heat exchange to liquefy air, and shaft work transfer by direct expansion of the LNG to compress the air.

TL;DR: In this article, the authors proposed a novel and advanced integration (denoted as LNG-LAES) for enhancements in flexibility, safety, and power generation, where LNG is re-gasified in two different manners: it flows into a parallel two-stage regenerative Rankine cycle for conventional power generation during peak times or transfers high-grade cold energy to LAES for energy storage during off-peak times.

TL;DR: In this paper, a combined liquid air energy storage (LAES) and LNG regasification process is proposed, in which the air is cooled via heat exchange with LNG and compressed by using the generated power from LNG.

TL;DR: In this paper, a comprehensive review of the geothermal energy systems is carried out from the perspective of systems analysis, design, and optimization, and the results illustrate that limited sets of parameters have been considered in most studies on design and optimization.

TL;DR: In this paper, the authors proposed an industrial-feasible design for the LNG-CES process and energy optimization to maximize net power output from the process, which demonstrated an 11.04% increase in the net power generation from the feasible configuration of the base design.
