Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Kohlenstoffdioxidgewinnung umfassend folgende Schritte: a) anodisches Oxidieren von Wasserstoffgas, wobei ein saures Oxidationsprodukt erhalten wird; b) Umsetzen des sauren Oxidationsproduktes mit einer alkalischen carbonathaltigen wässrigen Lösung, welche insbesondere einen pH-Wert von > 7 bis 9 aufweist, wobei eine saure wässrige Lösung erhalten wird; c) Entnahme von Kohlenstoffdioxid aus der sauren wässrigen Lösung, wobei Kohlenstoffdioxidgas und eine entgaste saure wässrige Lösung erhalten werden; d) kathodisches Reduzieren saurer Komponenten der entgasten sauren wässrigen Lösung, um kathodisch erzeugtes Wasserstoffgas zu erhalten, wobei zusätzlich eine alkalische wässrige Lösung erhalten wird, welche einen pH-Wert von 9,4 bis ≥ 8 aufweist.
