Kisik se lahko na podoben način proizvaja tudi z elektrokatalizo oksidov in oksi kislin. V kemičnih generatorjih kisika in kisikovih svečah, ki se uporabljajo v podmornicah in v komercialnih letalih med dekompresijo potniškega prostora, se uporabljajo tudi kemični katalizatorji. Ena od tehnologij za pridobivanja kisika je prisilno raztapljanje dušika s prepihavanjem zraka skozi keramične membrane iz cirkonijevega oksida pod visokim tlakom ali z električnim tokom, ki daje skoraj čist kisik.<sup id="cite_ref-FOOTNOTEEmsley2001301_40-1" class="reference"><a href="#cite_note-FOOTNOTEEmsley2001301-40"><span class="cite-bracket">[</span>40<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Skladiščenje"><span id="Skladi.C5.A1.C4.8Denje"></span>Skladiščenje</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Kisik&veaction=edit&section=19" title="Uredi razdelek: Skladiščenje" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Kisik&action=edit&section=19" title="Urejanje izvorne kode razdelka: Skladiščenje"><span>uredi kodo</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Iz litra tekočega kisika se pri 20 °C in atmosferskem tlaku razvije 840 litrov plinastega kisika, zato je bolj gospodarno njegovo skladiščenje in transportiranje v tekočem stanju v ustreznih toplotno izoliranih cisternah.<sup id="cite_ref-FOOTNOTECookLauer1968500_6-9" class="reference"><a href="#cite_note-FOOTNOTECookLauer1968500-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Tekoč kisik se pred uporabo uplini v toplotnih izmenjevalcih.
