Summary: This paper discusses the feasibility of using a photovoltaic energy system to produce hydrogen from solar energy in the four main cities of Iraq. A simulation of an off-grid photovoltaic system with an alkaline electrolyser, hydrogen compressor, and hydrogen tank was conducted for one year. The results show that the annual hydrogen production ranges from 1713.92 kg to 1891.12 kg, with an evaluated cost of $3.79/kg. The study suggests that the optimal sites for solar hydrogen production systems are in the midwest of Iraq and other cities with similar climates.

Summary: This study compares the design of PV-H2 hybrid systems with and without batteries, and finds that directly connected systems operate at intersection points between PV output and electrolyzer input curves, while battery assisted systems increase the size of electrolyzers. The study concludes that operating the electrolyzers at a fixed rate is not cost-effective, and recommends running at minimal load at night and adjusting daytime operations for null cumulative energy each season.

Summary: The aim of this study is to analyze a solar-driven unit on the non-interconnected island of Kythnos, Greece, which is capable of producing electricity and green hydrogen. The unit utilizes solar energy through parabolic trough collectors and stores the generated heat in a thermal energy storage tank. By incorporating an organic Rankine unit, electricity is generated to meet the island's demand, with excess power being stored as hydrogen for future use.

Summary: Green hydrogen production using wind energy as the electricity source has significant implications for energy transition and economy decarbonization. This study investigates the feasibility of hydrogen production from the WindFloat Atlantic offshore wind farm in Portugal. Results suggest that combining oxygen sales and allowing for production during both nights and afternoons can make the project more economically viable. Furthermore, the ratio between the hydrogen plant power and wind farm capacity has a notable impact on the cost of hydrogen production, with a minimum cost observed at a ratio of approximately 30%.

Summary: Hydrogen, a zero-pollution, sustainable, low-cost, and high-efficiency energy source, has great potential for the 21st century. Solar water-splitting techniques, such as photovoltaic-electrolysis (PV-EC) and photoelectrochemistry (PEC), have shown promise with solar-to-hydrogen conversion efficiency over 10%. However, there is a gap between laboratory research and practical application, which can be addressed by understanding the basic principles, historical developments, and performing comprehensive techno-economic analysis.
