Increased use of renewable energy sources is expected to contribute to long‐term sustainability and robust economic growth. A better global economy and lower greenhouse gas emissions are possible due to intensive research into more effective energy production, storage, and utilization technologies. The exciting solution for advancing the development of green hydrogen production and the clean transportation sector is the conversion of electrical energy generated from wind parks into green hydrogen. Therefore, herein, a technoeconomic optimization of hydrogen production for refueling fuel cell vehicles by comparing two different renewable energy sources is presented. Results obtained in this article demonstrate that Riyadh possesses sufficient wind speed and sunlight, which can be used to produce renewable hydrogen. It is evident from the evaluated and optimized results that the selected wind‐based hybrid energy system has the lowest net present cost, levelized cost of energy, and levelized cost of hydrogen of $247,654.00, $/kWh 0.1720, and $/kg 4.23, respectively, as compared to the other system counterpart, making the selected optimized hybrid energy system the preferred choice to fulfill the electricity and hydrogen production demand of the refueling fuel cell vehicles. It is expected that the stakeholders through this study can encourage the production of hydrogen in Saudi Arabia.

“…While striving for a carbon-free community powered by a sustainable economy, hydrogen has been considered an ideal solution for energy, green transportation, industry, and other domains. − In fact, hydrogen energy was thought to be the cleanest energy carrier since water was only the product from its combustion process. − Its high calorific value of 142.3 MJ/kg (three times higher compared to that value of gasoline) also makes it an efficient source of energy. , Figure illustrates hydrogen production technologies from other sources and hydrogen applications in many fields. , It could be seen that thermochemical conversion is considered as the most presently employed technology, and the majority of the hydrogen was derived from nonrenewable fossil feedstocks (such as natural gas, oil, and coal, oil) that are also associated with significant carbon emissions. , Thus, hydrogen is still a potentially game-changing species to attain carbon-free energy, but generating it without carbon emission is challenging. , Due to this reason, searching for sustainable hydrogen production technologies from noncarbon sources should be a prioritized approach for the energy sector in the future.…”

Hydrogen energy is environmental-friendly and considered an attractive alternative to fossil fuels. Among the feasible technologies for hydrogen generation, photocatalysis-derived hydrogen from water splitting is considered to be the optimal solution for meeting long-term sustainability and increased energy demands. In this context, various photocatalytic genres are proposed, with metal and carbon-supported photocatalysts demonstrating greater comprehensiveness and potential for addressing solar-driven hydrogen production from water. Several important aspects of the aforementioned photocatalytic genres are reviewed in the present work in an effort to provide pertinent researchers with new horizons for more advanced performance. The review is initiated by introducing the primary principles in photocatalysis, as well as the prerequisites for hydrogen generation from water. The focus then moves to metal-based photocatalysts, where the important features of these materials as photocatalysts are summarized. Related limitations are also discussed, along with the proposed strategies that could potentially mitigate them. Similar systematic summaries are made of knowledge on carbon-based photocatalysts. The review concludes with a discussion of potential future research directions in light of the bottlenecks currently encountered. With the proper research and development, metal-based and carbon-based photocatalysts could produce clean hydrogen from water, thereby fueling global development without causing environmental harm.

Offshore wind power is mostly of strong randomness and unpredictability, which brings a great challenge to proton exchange membrane (PEM) water electrolysis‐based hydrogen production. Besides, volatile temperature and pressure tend to impose prominent impacts on electrolyzer parameters as well. By analyzing the electrochemical characteristics of PEM electrolyzers, the electrochemical model of PEM electrolyzer in offshore wind power generation hydrogen production system is established. To ensure the control performance of PEM electrolyzers, the fractional‐order proportion integration differentiation (FOPID) control strategy and the improved firefly algorithm (IFA) are introduced, and the relevant parameters are optimized according to the overshoot and stability time as evaluation indicators. In order to adapt to the FOPID control requirements, a step‐type inertia weighting factor is employed to improve the classical firefly algorithm to avoid local optimum, and a mutation mechanism is used to expand the search range. Verification results show that the proposed IFAFOPID controller is superior to the traditional PID controller with a smaller overshoot and a shorter transition time subject to different disturbances, and thus is more beneficial to achieve precise voltage control and obtain stable hydrogen output.
