Installing multi-renewable energy (RE) power plants at designated locations, known as RE parks, is a promising solution to address their intermittent power. This research focuses on optimizing parks for three scenarios: photovoltaic (PV)-only, wind-only, and hybrid PV-wind, with the aim of generating green hydrogen in locations different potentials. To ensure rapid response fluctuations, Proton Exchange Membrane (PEM) electrolyzer employed. Furthermore, this proposes detailed models manufacturer-provided wind curves, efficiency against its operating power, cost towards capacity. Two optimization cases are conducted MATLAB, evaluating optimum sizes minimizing levelized (LCOH) using classical discrete combinatorial method determining ideal PV-to-wind capacity ratio PEM within PV-wind particle swarm optimization. Numerical simulations show that power-based production more cost-effective than PV-only parks. The lowest LCOH, $4.26/kg H2, highest $14.378/kg obtained from wind-only configurations, respectively. Both occurred Adum-Kirkeby, Denmark, it has average speed irradiance level. Notably, LCOH reduced configuration. results suggest 65:35 indicate sensitive electrolyzer's electricity tariff variation. study highlights two important factors, i.e., selecting suitable location based available resources size between park.

Metal node engineering, which can optimize the electronic structure and modulate composition of poor electrically conductive metal–organic frameworks, is great interest for electrochemical natural seawater splitting. However, mechanism underlying influence mixed-metal nodes on electrocatalytic activities still ambiguous. Herein, a strategic design comprehensively demonstrated in mixed Ni Co metal redox-active centers are uniformly distributed within NH2–Fe-MIL-101 to obtain synergistic effect overall enhancement activities. Three-dimensional metallic MOF nanosheet arrays, consisting three different nodes, were situ grown foam as highly active stable bifunctional catalyst urea-assisted A well-defined NH2–NiCoFe-MIL-101 reaches 1.5 cm–2 at 360 mV oxygen evolution reaction (OER) 0.6 295 hydrogen (HER) freshwater, substantially higher than its bimetallic monometallic counterparts. Moreover, electrode exhibits eminent catalytic activity stability seawater-based electrolytes.

Abstract Seawater electrolysis holds great promise for sustainable, green hydrogen production but faces challenges of high overpotentials and competing chlorine evolution reaction (CER). Replacing the oxygen with methanol oxidation (MOR) presents a compelling alternative due to its lower anodic potential which mitigates risk CER. While NiOOH is known MOR activity, performance limited by sluggish non‐electrochemical kinetics Cl‐induced degradation. Herein, MoO 4 2− ‐modified electrocatalyst reported that significantly enhances MOR‐assisted seawater splitting efficiency. In situ leached from heterojunction optimizes adsorption facilitates proton migration, thereby accelerating steps in MOR. Additionally, adsorbed effectively repels Cl − , protecting electrodes ‐induced corrosion. The electrolyzer using NiMo||Ni(OH) 2 /NiMoO₄ requires only 1.312 V achieve 10 mA cm −2 substantially than conventional alkaline (1.576 V). Furthermore, it demonstrates remarkable stability, sustaining current densities (up 1.0 A ) over 130 h. This work promising strategy designing high‐performance electrocatalysts efficient sustainable seawater.
