This gives them a broader perspective on the potential real-world applications of their knowledge. 5. Relate it to the Real-World: Cite Applications Chemistry, in general, is considered one of the most complex subjects as students fail to understand its relevance in the real world. Mostly that...
Direct seawater electrolysis eliminates the need for additional water purification processes provides an attractive pathway for hydrogen production in the oceans, but many challenges still exist. The composition of seawater is complex, containing at least 92 elements, many of which can exert a significan...
At last, the estimation of the PFNN model is achieved by utilizing a kernel function smoothing method to update the particles in each cluster. The proposed model has been tested on the real-world system for aluminium electrolysis manufacturing and compared with several closely related frameworks. ...
we found an increase in the CO adsorption energy and a decrease in the barrier for C–C coupling when a sub-monolayer coverage of OH*exists on
attention in recent years [3], partly because of the versatility of methane as a low-emissions energy carrier that makes it a suitable fuel for the transition to a fully renewable energy system [4]. Methanation processes offer the possibility to be integrated in so-called power-to-gas (PtG...
This phenomenon will impact the sensitivity of techno-economic parameters in the whole system electrolysis model, due to the consideration for the reduction of the lifetime of electrolysis stack, and reduced hydrogen production efficiency. The implementation of the contribution to overvoltage in the ...
Despite their theoretical promise of zero greenhouse gas emissions during production, real-world emissions vary based on system configurations and lifecycle assessments, highlighting the need for detailed evaluations of their environmental impact. Therefore, in this study, calculations were performed for the...

Furthermore, commercialization of PEMWE technology requires testing of PEMWE cells under real (more aggressive) working conditions, since most of the current PEM water electrolyzers have been tested in the laboratory under stationary conditions (temperature, current density, and pressure). All this lea...
Two types of contaminants were considered: 1—contaminants known to impact PEMFC performance (contaminants mentioned in the international standard ISO 14687:2019 [17]) and 2—contaminants emerging from seawater. A measurement of the hydrogen produced onboard a prototype is presented as evidence. This...
