Currently, pumped storage power plants provide the most large-scale storage in the world. Another option for large-scale system storage is compressed air energy storage (CAES). This paper discusses a particular case of CAES\u2014an adiabatic underwater energy storage system based on compressed air\u2014and its evaluation using advanced exergy analysis. The energy storage system is charged during the valleys of load and discharged at peaks. The model was built using Aspen HYSYS software. Advanced exergy analysis revealed interactions between system components and the potential for improving both system components individually and the system as a whole. The most significant reduction in exergy destruction can be achieved with heat exchangers. The round-trip efficiency of this system is 64.1% and 87.9% for real and unavoidable operation conditions, respectively.<\/jats:p>","DOI":"10.3390\/e25010077","type":"journal-article","created":{"date-parts":[[2023,1,2]],"date-time":"2023-01-02T04:17:38Z","timestamp":1672633058000},"page":"77","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Advanced Exergy Analysis of Adiabatic Underwater Compressed Air Energy Storage System"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6646-2297","authenticated-orcid":false,"given":"Lukasz","family":"Szablowski","sequence":"first","affiliation":[{"name":"Institute of Heat Engineering, Warsaw University of Technology, 00-665 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2968-4293","authenticated-orcid":false,"given":"Tatiana","family":"Morosuk","sequence":"additional","affiliation":[{"name":"Institute for Energy Engineering, Technische Universit\u00e4t Berlin, 10587 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"603","DOI":"10.1016\/j.egypro.2014.12.423","article-title":"Overview of current development in compressed air energy storage technology","volume":"62","author":"Luo","year":"2014","journal-title":"Energy Procedia"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"799","DOI":"10.1016\/j.applthermaleng.2008.05.020","article-title":"Optimal operation strategies of compressed air energy storage (CAES) on electricity spot markets with fluctuating prices","volume":"29","author":"Lund","year":"2009","journal-title":"Appl.
