The recent interest in the production of green hydrogen through water electrolysis is hampered by its high cost when compared to steam methane reforming. To overcome this disadvantage, some studies explore replacing oxygen with peroxide at anode, which has a higher value. Existing electrocatalysis research primarily focuses on synthesis, neglecting process design and separation. Additionally, peroxide's thermodynamic instability alkaline conditions existence other ions make separation difficult. This paper proposes novel concept for paired that can be used improve economics valuable chemical coproductions. Valorizing sodium percarbonate as final product was chosen address challenges. An electrolyzer stack 2 MW chosen, incorporating recirculating structure, boron-doped diamond anode enhance base case. According techno-economic analysis, stack, capital expenditure calculated 64.5 M€, operational expenses 21.6 revenue 2.5 resulting negative cash flow −19.1 M€. Results revealed profitable (breakeven point) capacity approximately 308 stacks, 616 capacity. A sensitivity analysis conducted determine how drivers including electricity price, Faradaic efficiency, price products tax subsidy affect breakeven point. point 60 stacks (120 MW) found 100% increase sale price. In comparison, theoretical efficiency material would result 38 (76 MW). Even more realistic 75% leads plant size 75 (150 Further, multiple two-parameter analyses were assess relations between For instance, if increases 75%, drops down 13 (26 Despite facing economic challenges proposed based available technologies, highlights key targets future works. It also provides insights into feasibility simultaneously producing electrolysis, indicating promising potential future.

Abstract H 2 O production in coupled electrochemical systems, where is generated through 2e‐pathway of water oxidation (2e‐WOR) at anode and oxygen reduction (2e‐ORR) cathode, offers an advanced alternative to the anthraquinone process. However, efficiency such system often hindered by limited activity selectivity electrocatalysts. Herein, a dual‐functional catalyst composed amorphous TiO embedded mesoporous carbon hollow spheres (TiO x @MCHS) reported, which exhibits exceptional electrocatalytic performance for both 2e‐WOR 2e‐ORR. By employing @MCHS‐loaded electrodes as cathode membrane‐free flow cell with 4 м K CO 3 /KHCO electrolyte, rate 108.3 µmol min −1 cm −2 Faradaic (FE) ≈145% are achieved voltage ≈2.5 V under constant current 240 mA (anode: 1 , cathode: ). Experimental computational results reveal crucial role low‐coordinated Ti optimizing adsorption intermediates involved two electrode reaction pathways, thereby enhancing these processes. This work establishes new paradigm development electrocatalysts design novel coupled‐electrolysis enabling scalable sustainable electrosynthesis.
