Comparative Study of LNG, Liquid Hydrogen ,and Liquid Ammonia Post-release Evaporation and Dispersion During Bunkering
Apr 2024
Publication
The use of alternative fuels is a primary means for decarbonising the maritime industry. Liquefied natural gas (LNG) liquid hydrogen (LH2) and liquid ammonia (LNH3) are liquified gases among the alternative fuels. The safety risks associated with these fuels differ from traditional fuels. In addition to their low-temperature hazards the flammability of LNG and LH2 and the high toxicity of LNH3 present challenges in fuel handlings due to their high likeli Read More
Strategic Optimization and Design of Cost-effective and Sustainable Hydrogen Supply Chain Networks - Qatar Case Study
Jan 2025
Publication
This study introduces a multi-period integrated optimization model for designing a strategic hydrogen supply chain (HSC) network concentrating on the post-production stages of conditioning storage transportation and post-conditioning. Qatar serves as the case study for evaluating three HSC pathways—ammonia (as a hydrogen carrier) liquefied hydrogen and compressed hydrogen—across pre-conditioning storage shipping and postconditioning stages. The Read More
Hydrogen Underground Storage in Silica-Clay Shales: Experimental and Density Functional Theory Investigation
Nov 2023
Publication
In the context of reducing the global emissions of greenhouse gaseshydrogen (H2) has become an attractive alternative to substitute the current fossil fuels.However its properties seasonal fluctuations and the lack of extended energy stabilitymade it extremely difficult to be economically and safely stored for a long term in recentyears. Therefore this paper investigated the potential of shale gas reservoirs (rich andlow clay−rich silica minerals) to sto Read More
Wind-powered Hydrogen Refueling Station with Energy Recovery for Green Mobility in Sustainable Cities
Jan 2025
Publication
This study presents the conceptual design and evaluation of an HRS for light-duty FCEVs. The proposed system integrates wind turbines a water electrolyzer three-stage hydrogen compressor heat recovery and storage a two-stage Organic Rankine Cycle (TS-ORC) hydrogen storage tanks a Vapor Compression Refrigeration Cycle (VCRC) and a hydrogen dispenser. Waste heat from the hydrogen compression process is harnessed to power the TS-ORC whe Read More
A Comprehensive Review of Hydrogen Safety through a Metadata Analysis Framework
Feb 2025
Publication
Hydrogen is widely recognized as a promising clean energy carrier but its highly flammable and explosive nature presents significant safety challenges in its production storage transportation and usage. Addressing these challenges is critical for the successful integration of hydrogen into global energy systems aligning with the United Nations’ sustainable development goals to support the transition to a low-carbon future. This study aims to provide a com Read More
