Generation of Hydrogen and Oxygen from Water by Solar Energy Conversion
Dec 2021
Publication
Photosynthesis is considered to be one of the promising areas of cheap and environmentally friendly energy. Photosynthesis involves the process of water oxidation with the formation of molecular oxygen and hydrogen as byproducts. The aim of the present article is to review the energy (light) phase of photosynthesis based on the published X-ray studies of photosystems I and II (PS-I and PS-II). Using modern ideas about semiconductors and biolo Read More
Hydrogen Embrittlement in Pipelines Transporting Sour Hydrocarbons
Sep 2017
Publication
Lamination-like defects in pipeline steels can be of both metallurgical and operational origin. In pipelines transporting hydrocarbon usually such defects are not a big challenge since they do not propagate under operating conditions. Nonetheless in presence of a corrosion phenomenon and sour gas (H2S) it is possible to observe blisters and cracks which may propagate in the steel. The observed damage mechanisms is Hydrogen Embrittlement and in sp Read More
Ranking Locations for Hydrogen Production Using Hybrid Wind-Solar: A Case Study
Apr 2021
Publication
Observing the growing energy demand of modern societies many countries have recognized energy security as a looming problem and renewable energies as a solution to this issue. Renewable hydrogen production is an excellent method for the storage and transfer of energy generated by intermittent renewable sources such as wind and solar so that they can be used at a place and time of our choosing. In this study the suitability of 15 cities in F Read More
Resource Assessment for Green Hydrogen Production in Kazakhstan
Jan 2023
Publication
Kazakhstan has long been regarded as a major exporter of fossil fuel energy. As the global energy sector is undergoing an unprecedented transition to low-carbon solutions new emerging energy technologies such as hydrogen production require more different resource bases than present energy technologies. Kazakhstan needs to consider whether it has enough resources to stay competitive in energy markets undergoing an energy transition. Green hyd Read More
Increasing Technical Efficiency of Renewable Energy Sources in Power Systems
Mar 2023
Publication
This paper presents a method for refining the forecast schedule of renewable energy sources (RES) generation by its intraday adjustment and investigates the measures for reserving RES with unstable generation in electric power systems (EPSs). Owing to the dependence of electricity generation by solar and wind power plants (PV and WPPs respectively) on natural conditions problems arise with their contribution to the process of balancing the power s Read More
A Mini-review on Recent Trends in Prospective Use of Porous 1D Nanomaterials for Hydrogen Storage
Nov 2021
Publication
The sustainable development of hydrogen energy is a priority task for a possible solution to 26 the global energy crisis. Hydrogen is a clean and renewable energy source that today is used 27 exclusively in the form of compressed gas or in liquefied form which prevents its widespread 28 use. Storing hydrogen in solid-state systems will not only increase the bulk density and 29 gravimetric capacity but will also have a positive impact on safety issues. From th Read More
Solar-Powered Water Electrolysis Using Hybrid Solid Oxide Electrolyzer Cell (SOEC) for Green Hydrogen—A Review
Nov 2023
Publication
The depletion of fossil fuels in the current world has been a major concern due to their role as a primary source of energy for many countries. As non-renewable sources continue to deplete there is a need for more research and initiatives to reduce reliance on these sources and explore better alternatives such as renewable energy. Hydrogen is one of the most intriguing energy sources for producing power from fuel cells and heat engines without rel Read More
High-Entropy Alloys: Innovative Materials with Unique Properties for Hydrogen Storage and Technologies for Their Production
Jan 2025
Publication
This paper presents a review of a number of works devoted to the studies of high-entropy alloys (HEAs). As is known HEAs represent a new class of materials that have attracted the attention of scientists due to their unique properties and prospects of application in hydrogen power engineering. The peculiarity of HEAs is their high entropy of mixing which provides phase stability and flexibility in developing materials with given characteristics. The main focus Read More
