Abstract The economics of conventional water electrolysis is restricted by the energy‐intensive oxygen evolution. To address this, we fabricate nanoneedle‐like NiCo 2 O 4 electrocatalyst capable of achieving efficient selective glycerol electrooxidation at low potential of 1.35 V vs. RHE, facilitated by synergistic redox cycling between Ni and Co sites in electrogenerated Ni/Co(OOH) species. Stable electrolysis at 500 mA cm −2 for 240 h markedly reduces the cell voltage by 551 mV and the energy consumption by 1.59 kWh Nm −3 H 2 as compared to water splitting. Impressively, we establish an industrial‐scale integrated electrolysis system with 11 electrode pairs (10 × 10 cm 2 each), enabling high production of potassium diformate within a short period of time. Techno‐economic analysis confirms strong profitability for the coupled system, validating a feasible “green‐hydrogen‐production‐sustained‐by‐chemical‐revenue” paradigm. This work offers a high‐performance spinel‐based anode material that efficiently drives coproduction of high‐value‐added chemical and hydrogen at the industrial level.
