In the coming years, European Union plans to establish Proton Exchange Membrane (PEM) electrolyzers, each with a 100 MW capacity. However, selection of their locations has not been systematically optimized leverage potential benefits, such as utilizing waste heat from large facilities for district heating. Presently, there are hardly any corresponding system models in literature dynamically simulating PEM electrolyzer this size. This paper introduces first model approach systems, drawing on parameters existing literature. It addresses inconsistency found regarding use exchange current density, which varies by factor 109. A novel optimization process is developed using an auxiliary parameter fit density newfound condition between anode and cathode side. The outcome comprehensive plant, exemplarily adapted Siemens Silyzer 300.

Energy and exergy-economic performance comparison of wind, solar pond, and ocean thermal energy conversion systems for green hydrogen production

International Journal of Hydrogen Energy, Год журнала: 2024, Номер unknown

The necessity of energy solutions that are economically viable, ecologically sustainable and environmentally friendly has become fundamental to economic societal advancement nations. In this context, renewable sources emerge as the most vital component. Furthermore, hydrogen generation systems based on energies increasingly recognized crucial strategies mitigate global warming. present study, a comparative analysis is conducted from an exergy-economic perspective find efficient configuration among three different for renewable-based power production. These wind turbine, salinity gradient solar pond (SGSP), ocean thermal conversion (OTEC). SGSP OTEC coupled with production unit by trilateral cycle (TLC) improve temperature match heating process. heat waste within these recovered thermoelectric generator (TEG), proton exchange membrane electrolyzer (PEME) used Under base case input conditions, net PEME estimated be approximately 327.8 kW across all configurations. Additionally, 3E (energy, exergy, exergy-economic) performance evaluated parametric study design optimization. results best reveal exergy efficiency achievable wind-based system in range 5.8–10.47% average speed 8–12 m/s. Correspondingly, favorable total cost rate attributed at 8 m/s, equating 66.08 USD/h. Subsequently, SGSP-based economical, ranging 42.78 44.31 USD/GJ.
