Here, we demonstrate a single-step, energy-efficient bipolar membrane electrodialysis (BMED) system integrated with CCU, enabling the simultaneous conversion of NaCl brine and CO2 into high-purity sodium bicarbonate (NaHCO3) with unprecedented efficiency, but without requiring external alkali sources or energy-intensive thermal regeneration steps. By optimizing key parameters \u2013 such as current density and CO2 aeration rate, and gas\u2013liquid flow ratios \u2013 we achieved a bicarbonate concentration of 1.186 mol\/L in the alkaline chamber, coupled with 57.65% carbon sequestration efficiency and an energy consumption as low as 3.1 kW\u00b7h\/m\u00b3 CO2 (or 716.9 kW\u00b7h\/t NaHCO3). This approach not only recovers valuable sodium resources from brine but also enhances CO2 absorption through electrochemical mechanisms, potentially reducing global carbon emissions by up to 20% in brine-intensive industries. Our work paves the way for scalable, sustainable CCUS technologies, transforming waste streams into economic assets and advancing the fight against climate change.<\/jats:p>","DOI":"10.2166\/wst.2025.085","type":"journal-article","created":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T23:52:37Z","timestamp":1751068357000},"page":"127-138","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":4,"title":["A sustainable bipolar membrane electrodialysis process for effective conversion of CO2 and NaCl brine into NaHCO3"],"prefix":"10.2166","volume":"92","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6893-2010","authenticated-orcid":false,"given":"Wei","family":"Wang","sequence":"first","affiliation":[{"name":"a National Institute of Clean-and-Low-Carbon Energy, Beijing 102211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoxuan","family":"Li","sequence":"additional","affiliation":[{"name":"b Engineering Research Center of Seawater Utilization of Ministry of Education, School of Chemical Engineering and Technology, Hebei University of Technology, Tianjin 300401, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Xie","sequence":"additional","affiliation":[{"name":"b Engineering Research Center of Seawater Utilization of Ministry of Education, School of Chemical Engineering and Technology, Hebei University of Technology, Tianjin 300401, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingying","family":"Zhao","sequence":"additional","affiliation":[{"name":"b Engineering Research Center of Seawater Utilization of Ministry of Education, School of Chemical Engineering and Technology, Hebei University of Technology, Tianjin 300401, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rihua","family":"Xiong","sequence":"additional","affiliation":[{"name":"a National Institute of Clean-and-Low-Carbon Energy, Beijing 102211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"key-10.2166\/wst.2025.085-1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.iecr.6b04617"},{"key":"key-10.2166\/wst.2025.085-2","doi-asserted-by":"publisher","DOI":"10.3390\/min7110207"},{"key":"key-10.2166\/wst.2025.085-3","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2024.155092"},{"key":"key-10.2166\/wst.2025.085-4","doi-asserted-by":"publisher","DOI":"10.1021\/ie402538d"},{"key":"key-10.2166\/wst.2025.085-5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jgsce.2023.205070"},{"key":"key-10.2166\/wst.2025.085-6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclepro.2018.04.046"},{"key":"key-10.2166\/wst.2025.085-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.desal.2017.02.005"},{"key":"key-10.2166\/wst.2025.085-8","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemmater.0c02829"},{"key":"key-10.2166\/wst.2025.085-9","doi-asserted-by":"publisher","DOI":"10.1021\/acs.energyfuels.8b01666"},{"key":"key-10.2166\/wst.2025.085-10","doi-asserted-by":"publisher","DOI":"10.1016\/j.seppur.2013.04.053"},{"key":"key-10.2166\/wst.2025.085-11","doi-asserted-by":"publisher","DOI":"10.1021\/acs.est.8b00980"},{"key":"key-10.2166\/wst.2025.085-12","doi-asserted-by":"publisher","DOI":"10.1016\/j.fuproc.2012.01.023"},{"key":"key-10.2166\/wst.2025.085-13","doi-asserted-by":"publisher","DOI":"10.1016\/j.seppur.2020.116795"},{"key":"key-10.2166\/wst.2025.085-14","doi-asserted-by":"publisher","DOI":"10.3390\/cleantechnol4040073"},{"key":"key-10.2166\/wst.2025.085-15","doi-asserted-by":"publisher","DOI":"10.1021\/es102671x"},{"key":"key-10.2166\/wst.2025.085-16","doi-asserted-by":"publisher","DOI":"10.1080\/19443994.2012.715421"},{"key":"key-10.2166\/wst.2025.085-17","doi-asserted-by":"publisher","DOI":"10.1016\/j.seppur.2023.125331"},{"key":"key-10.2166\/wst.2025.085-18","doi-asserted-by":"publisher","DOI":"10.4491\/eer.2016.042"},{"key":"key-10.2166\/wst.2025.085-19","doi-asserted-by":"publisher","DOI":"10.1039\/D4EE00048J"},{"key":"key-10.2166\/wst.2025.085-20","doi-asserted-by":"publisher","DOI":"10.1038\/nclimate2882"},{"key":"key-10.2166\/wst.2025.085-21","doi-asserted-by":"publisher","DOI":"10.1016\/j.memsci.2014.09.006"},{"key":"key-10.2166\/wst.2025.085-22","doi-asserted-by":"publisher","DOI":"10.1021\/ie400284v"},{"key":"key-10.2166\/wst.2025.085-23","doi-asserted-by":"publisher","DOI":"10.1016\/j.apenergy.2019.03.138"},{"key":"key-10.2166\/wst.2025.085-24","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2024.159082"}],"container-title":["Water Science &amp;
