“…The yearly quantity of hydrogen required by the UAVs, assuming full power at all times (a conservative hypothesis), and a fuel cell efficiency of 55 %, is 3.2•10 8 kg, while the current worldwide hydrogen production is 7.5•10 10 kg per year (Li et al, 2023). Hence, the hydrogen required by the system would correspond to about 0.4 % of the hydrogen produced every year, as of now.…”

Marine cloud brightening can be obtained using a system with lab-generated salt particles, dispersed using Unmanned Aerial Vehicles (UAVs).• Salt nanoparticles generated by this system have a narrow size distribution, saving weight and making UAVs a viable solution for dispersion.• Preliminary analysis shows that this system could be more readily developed, and would cost less than a ship-based system.

“…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.

“…Firstly, the increased availability of renewable energy sources can reduce the amount of energy derived from burning fossil fuels, which is the primary source of CO 2 emissions in the majority of developing countries (Adebayo et al 2023 ; Caglar and Askin 2023 ; Li 2023 ; Karaaslan and Camkaya 2022 ). Secondly, the introduction of renewable energy sources can help to reduce the cost of energy, making it more affordable for individuals and businesses in developing countries, which in turn reduces the amount of energy consumed and reduces related CO 2 emissions (Li et al 2023 ; Zhang et al 2023 ; Yan et al 2023a ; Razzaq et al 2023 ). Finally, the increased use of renewable energy sources can help to create jobs (Candra et al 2023 ; Hanna et al 2023 ; Wang et al 2023 ) and stimulate economic growth in developing countries, which can also help to reduce CO 2 emissions (Sadiq et al 2023 ; Nahrin et al 2023 ; Adebayo et al 2023 ; Mukhtarov et al 2023 ).…”

In this study, energy losses, energy prices, and the relationship between green energy and environmental quality are investigated for 15 energy-importing emerging economies. In addition, the validity of the environmental Kuznets curve is tested in this study. Autoregressive Distributed Lag (ARDL) approach based on panel dataset, related intermediate estimators including PMG, MG, and DFE were used as a method. In addition, FMOLS and DOLS estimators were used for robustness testing in the study. According to empirical findings, the environmental Kuznets curve is valid in energy-importing emerging economies. In addition, green energy use and energy prices have a reducing effect on CO 2 emissions. However, energy losses increase CO 2 emissions. While the long-term results of the variables were similar, the short-term results were mixed. This situation is attributed to different economic growths in energy-importing developing economies, the share of energy resources in total energy resources, and energy-efficient technologies in the energy field. The fact that these variables have never been investigated for this economy group makes the study different. Graphical Abstract
