These focus on capturing CO2 from industrial exhaust gases and transporting it through existing pipeline networks. Although various capture techniques are available, they may introduce impurities such as O2, N2, Ar, H2O, NH3, and others into the CO2 stream. These contaminants can significantly alter the thermophysical behaviour of the fluid, making the phase behaviour predictions, reliable for pure CO2, much more complex. Pressure and temperature variations along pipelines can induce unexpected phase transitions, affecting fluid composition and potentially triggering corrosion. This review examines the formation of condensates within pipelines and their role in initiating corrosion phenomena, with a focus on top of the line corrosion (TLC) and conventional CO2-induced corrosion (sweet corrosion). The main literature findings highlight how phase changes and altered fluid composition due to corrosion processes can significantly intensify degradation mechanisms during CO2 transport.<\/jats:p>","DOI":"10.3390\/ma19102048","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T07:50:15Z","timestamp":1778745015000},"page":"2048","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Corrosion Behaviour in CO2 Pipeline Transport: A Review of the Impact of Condensates and Impurities"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9454-7984","authenticated-orcid":false,"given":"Luca","family":"Gritti","sequence":"first","affiliation":[{"name":"Department of Engineering Applied Science, University of Bergamo, 24044 Dalmine, Italy"},{"name":"INSTM, Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali, 50121 Firenze, Italy"},{"name":"CSGI, Consorzio Interuniversitario per lo sviluppo dei Sistemi a Grande Interfase Center for Colloid and Surface Science, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1217-4983","authenticated-orcid":false,"given":"Denny","family":"Coffetti","sequence":"additional","affiliation":[{"name":"Department of Engineering Applied Science, University of Bergamo, 24044 Dalmine, Italy"},{"name":"INSTM, Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3135-6996","authenticated-orcid":false,"given":"Lorenzo","family":"Nani","sequence":"additional","affiliation":[{"name":"Department of Engineering Applied Science, University of Bergamo, 24044 Dalmine, Italy"},{"name":"INSTM, Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali, 50121 Firenze, Italy"},{"name":"CSGI, Consorzio Interuniversitario per lo sviluppo dei Sistemi a Grande Interfase Center for Colloid and Surface Science, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1337-7590","authenticated-orcid":false,"given":"Sergio","family":"Lorenzi","sequence":"additional","affiliation":[{"name":"Department of Engineering Applied Science, University of Bergamo, 24044 Dalmine, Italy"},{"name":"INSTM, Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali, 50121 Firenze, Italy"},{"name":"CSGI, Consorzio Interuniversitario per lo sviluppo dei Sistemi a Grande Interfase Center for Colloid and Surface Science, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3901-8657","authenticated-orcid":false,"given":"Marina","family":"Cabrini","sequence":"additional","affiliation":[{"name":"Department of Engineering Applied Science, University of Bergamo, 24044 Dalmine, Italy"},{"name":"INSTM, Consorzio Interuniversitario Nazionale per la Scienza e Tecnologia dei Materiali, 50121 Firenze, Italy"},{"name":"CSGI, Consorzio Interuniversitario per lo sviluppo dei Sistemi a Grande Interfase Center for Colloid and Surface Science, 50019 Sesto Fiorentino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,14]]},"reference":[{"key":"ref_1","unstructured":"Masson-Delmotte, V., Zhai, P., P\u00f6rtner, H.-O., Roberts, D., Skea, J., Shukla, P.R., Pirani, A., Moufouma-Okia, W., P\u00e9an, C., and Pidcock, R.
