Desalinating seawater generally produces brine as a by-product that cannot be purified economically with current technologies and which is instead released to the environment. In this Perspective, we discuss direct electrosynthesis of sodium hydroxide (NaOH) and hydrochloric acid (HCl) from sea-water desalination brine as an emerging alternative solution. In this direct electrosynthesis (DE) process, the water splitting reaction is used to produce H+ and OH–, which combine with the brine stream to produce NaOH and HCl. After introducing the scope of the process, we describe developments in earth-abundant catalysts for water splitting and the competing chlorine evolution reaction (CER), as well as challenges in inefficiency and productivity associated with these processes. Finally, we discuss the economic impact and feasibility of direct electrosynthesis.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Direct electrosynthesis of sodium hydroxide and hydrochloric acid from brine streams","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:33:17.380843","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2019-04-15","DateCreate":"2019-04-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000458554800005","VABBcode":null,"OpenAcc":0,"DOI":"10.1038/s41929-018-0218-y"},"refs":null,"anarec":{"AnaID":310308,"PubliDate":2019,"Pagination":"106-113","XtraPublOfAnaID":null,"ISBN":null,"Volume":"2","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":310307,"SerRR":"Nature Catalysis.
