Replacing the kinetically sluggish and energy-intensive oxygen evolution reaction (OER) at anode with oxidation of more thermodynamically favorable small organic molecules is a promising strategy for boosting hydrogen production. This study focuses on sustainable generation cathode facilitated by ethylene glycol (EGOR) anode, coupled production value-added formate. For this, we designed deposited cobalt- iron-based fluorinated two-dimensional (2D)-nanosheets (2D-CoFe@OF) through straightforward hydrothermal method onto nickel foam substrate (NF). The resulting 2D-CoFe@OF/NF exhibits an anodic potential that 100 mV lower in 0.5 M EG-added 1.0 KOH electrolyte to achieve benchmark electrolysis current density 10 mA cm–2, compared pure electrolyte. Additionally, assembling two identical 2D-CoFe@OF/NF||2D-CoFe@OF/NF electrode-based electrolyzers resulted 150 reduction operating cell voltage when electrolyzing particularly OER was replaced EGOR, thereby demonstrating significant improvement energy efficiency. Under this condition, electrolyzer demonstrated nearly 100% Faradaic efficiency (HER). Furthermore, practical application system studied EG-seawater suggests its replace freshwater abundant seawater, expanding horizon generation. study, thus, highlights 2D-CoFe@OF nanosheets EGOR advancing green technology toward future.

Green Hydrogen Production From Non‐Traditional Water Sources: A Sustainable Energy Solution With Hydrogen Storage and Distribution

The Chemical Record, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 23, 2024

Abstract Green hydrogen development plays an essential role in creating a sustainable and environmentally conscious society while reducing reliance on traditional fossil fuels. Proton Exchange Membrane Water Electrolysers (PEMWEs), are sensitive to water quality, with various impurities impacting their efficiency, the quality of produced, device‘s lifespan. High‐purity is required for PEM electrolyzers; Type II water, which commercial electrolyzers, must have resistivity greater than 1 MΩ cm, sodium, chloride concentrations less 5 μg/L, total organic carbon (TOC) content 50 parts per billion. The majority electrolyzers operate freshwater, or dissolved solids (TDS) <0.5 g/kg, whereas brackish, rainwater, wastewater, seawater TDSs 1–35 0.01–0.15 0.5–2 35–45 respectively. This critical review offers, first time, comprehensive overview relevant operating impact. findings this study indicate that electrolysis‐based H 2 processes promising options contribute production capacity but require improvements produce larger competitive volumes. In addition, main challenges opportunities generating, storing, transporting, distributing hydrogen, as well large‐scale adoption discussed.
