The poor performance of the cold thermal energy storage is a bottleneck to achieve cost-effectiveness of the system. The objective of this paper is to identify the most appropriate storing material to be used in cold packed bed energy storage. Four types of storing materials, three sensible heat materials and a latent heat material with cryogenic phase change materials, were evaluated. Thermodynamic models for the components of the system integrated with a 1-dimensional transient numerical model, the concentric dispersion model, of the packed bed system were developed. The total number of required packed bed tanks and the cost of the cold thermal energy storage were estimated for each material. The results suggest an optimum charging pressure of 18.5 MPa, and a discharging pressure of 10 MPa for the liquid air energy storge system with a capacity of 100 MW as input power and a constant capacity of cold thermal energy storage. The maximum round-trip efficiency and the liquid air yield of the system are 50.2 % and 69.3 %, respectively.

This paper presents a new approach for cycles within which expansion is contained within the two-phase region (which can include the trilateral flash cycle and partial evaporation organic Rankine cycle), based upon fundamental thermodynamic relations. Thermodynamic properties need only be determined for saturated and liquid states, which along with system constants and independent variables, allows for the rapid evaluation of important cycle parameters. In this paper, a definition is provided for a two-phase power cycle, governing equations are presented, and the thermodynamic derivation of the model is provided. The different types of working fluid are discussed with respect to the considerations which must be made for each. Lastly, a comparison between three simple algorithms (proposed model, hybrid model, and conventional model) is presented to demonstrate the validity of the proposed model and the improvements possible over the conventional method. Results show that the algorithm running the proposed model shows substantial improvements when compared to the conventional approach, demonstrating an improvement in runtime by a factor of 44.77, a reduction in cyclomatic complexity of 72.73%, and a reduction in reliance upon equations of state of 99.72%, with no compromises in accuracy.</div></div>","PeriodicalId":23062,"journal":{"name":"Thermal Science and Engineering Progress","volume":"60 ","pages":"Article 103415"},"PeriodicalIF":5.1,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
