Energies, Год журнала: 2024, Номер 17(21), С. 5512 - 5512

Опубликована: Ноя. 4, 2024

This study develops a semi-empirical model of an alkaline water electrolyzer (AWE) based on thermodynamic and electrochemical principles to investigate cell voltage behavior during electrolysis. By importing polarization curve test data under specific operational conditions, eight undefined parameters are precisely fitted, demonstrating the model’s high accuracy in describing characteristics electrolyzers. Additionally, AWE system is introduced examine influence various efficiency. innovative approach not only provides detailed insights into dynamics systems but also offers valuable tool for optimizing performance enhancing efficiency, advancing understanding optimization technologies.

Frontiers in Marine Science, Год журнала: 2024, Номер 11

Опубликована: Июль 4, 2024

Green hydrogen is an important future energy source, which offers a vast potential to implement the decarbonization of marine sector and advance broad shift clean-energy alternatives globally. There are various advantages offshore floating photovoltaics (FPVs) technology for production; however, storage in FPVs-based production system faces several challenges. It found that major barrier concerning under investigation related safety. The current study aims present applicable system, involves both FPV section based on project China. A numerical 3D model performed investigate characteristics accidental damage through device failure during operation. release process presented with different wind conditions, parameters understanding motion state mode also analyzed. further explores dynamic development dispersion from platform, including momentum-dominated region, horizontal spreading vertical buoyancy region. In addition, influence explosive flame thermal evaluation illustrated, hazards conditions discussed. contributes better analysis FPVs–hydrogen elaborates evolution integrated system. concentrates environmental synergistic limits considering thermally damaged mechanical properties.
