Experimental Investigation and Evaluation of Newly Designed Electrodes for Hydrogen Production in Alkaline Water Electrolysis
Jan 2025
Publication
Alkaline water electrolysis is a promising clean hydrogen production technology that accounts for a small percentage of global hydrogen production. Therefore the technique requires further research and development to achieve higher efficiencies and lower hydrogen production costs to replace the utilization of non-renewable energy sources for hydrogen production. In this study electrodes are fabricated through fused deposition modelling 3 Read More
Techno-economic Assessment of a Solar-powered Green Hydrogen Storage Concept Based on Reversible Solid Oxide Cells for Residential Micro-grid: A Case Study in Calgary
Feb 2025
Publication
Solar photovoltaic (PV)-based electricity production has gained significant attention for residential applications in recent years. However the sustainability and economic feasibility of PV systems are highly dependent on their grid-connected opportunities which may diminish with the increasing penetration of renewable energy sources into the grid. Therefore securing reliable energy storage is crucial for both grid-connected and off-grid PV-based reside Read More
Integration of a Model-based System Engineering Framework with Safety Assessment for Early Design Phases: A Case Study for Hydrogen-based Aircraft Fuel System Architecting
Feb 2025
Publication
Novel hydrogen-based aircraft concepts pose significant challenges for the system development process. This paper proposes a generic adaptable and multidisciplinary framework for integrated model-based systems engineering (MBSE) and model-based safety assessment (MBSA) for the conceptual design of complex systems. The framework employs a multi-granularity modelcentric approach whereby the architectural specification is utilized for desi Read More
Hydrogen Pipelines and Embrittlement in Gaseous Environments: An Up-to-date Review
Mar 2025
Publication
Pipelines represent the most economical and efficient means for transporting hydrogen in large volumes across vast distances contributing to accelerated realization of hydrogen economy. Nowadays the development of hydrogen pipeline projects including repurposing existing pipelines for hydrogen service has become a global interest especially in those major energy-producing and energy-consuming countries. However steel pipelines are susceptible to Read More
Development of a Novel Thermochemical Cycle Without Electrolysis Step to Produce Hydrogen
Jan 2025
Publication
This study presents a new three-step Cu-Cl cycle that can operate with heat input without electrolysis. While the sensitivity analyses of the system are performed to evaluate the system performance through the Aspen Plus thermodynamic analyses of the system are performed with energetic and exergetic approaches. The highest exergy destruction among the components in the system was the decomposition reactor with a rate of 50.6%. Furtherm Read More
