From seawater to hydrogen via direct photocatalytic vapor splitting: A review on device design and system integration

Frontiers in Energy 2024年第3期18卷 291-307页

Solar-driven hydrogen production from seawater attracts great interest for its emerging role in decarbonizing global energy consumption. Given the complexity of natural seawater content, photocatalytic vapor splitting offers a low-cost and safe solution, but with a very low solar-to-hydrogen conversion efficiency. With a focus on cutting-edge photothermal–photocatalytic device design and system integration, the recent research advances on vapor splitting from seawater, as well as industrial implementations in the past decades were reviewed. In addition, the design strategies of the key processes were reviewed, including vapor temperature and pressure control during solar thermal vapor generation from seawater, capillary-fed vaporization with salt repellent, and direct photocatalytic vapor splitting for hydrogen production. Moreover, the existing laboratory-scale and industrial-scale systems, and the integration principles and remaining challenges in the future seawater-to-hydrogen technology were discussed.

Depositional Environment, Petrophysical Evaluation and Electrical Properties of Zeit Formation, Northwestern Shore of Gulf of Suez, Egypt

引用

Journal of Earth Science 2024年第5期35卷 1720-1737页

作者： mohamed M.Gomaa Emad A.Abd El Aziz Geophysical Sciences Department National Research Centre

The Zeit sand reservoir is one of the most prolific formations at Northwestern side of the Gulf of Suez. In this research we will try to coordinate between electrical, petrophysical properties, depositional environment and facies discrimination in order to evaluate the hydrocarbon potentiality of studied Zeit Formation. The statistical parameters for potassium（K）, thorium（Th） and Th/U ratio contents have a general increase towards northwestern parts, whereas uranium（U） content has a general increase towards southeastern parts. The sandstone facies is distinguished from the other facies by its thorium content >4 ppm. U has high carbonate content（U ≥ 1 ppm）. Rocks' electrical properties vary greatly depending on a number of factors. Electrical measurements were taken at frequencies range of(5 × 10-4Hz–100 kHz) for fully saturated samples（clayey sandstone） with NaCl（20 gm/l）. As salinity, clay content, and frequency increase, consequently does the electrical properties. The continental condition are present in northwestern part（back-sea） which is distinguished by high K percent, high Th, high Th/U ratio, and low U contents. low K, Th, and Th/U ratio contents, with high U contents, characterize the marine depositional environment that existed around the east and southeastern parts（foresea coincide with the dipping of strata）. Furthermore, the studied Zeit Formation has good petrophysical properties that coincide with marine conditions. The middle and eastern parts（around ISS-94 and CSS-288） is a good reservoir（porosity 36%–39%, shale content ration 71%–92%, and net pay thickness 17–63 feet）.
