Evaluation of Sourcing Decision for Hydrogen Supply Chain Using an Integrated Multi-Criteria Decision Analysis (MCDA) Tool
Apr 2023
Publication
The use of fossil fuels has caused many environmental issues including greenhouse gas emissions and associated climate change. Several studies have focused on mitigating this problem. One dynamic direction for emerging sources of future renewable energy is the use of hydrogen energy. In this research we evaluate the sourcing decision for a hydrogen supply chain in the context of a case study in Thailand using group decision making analysis for Read More
Technical, Economic, Carbon Footprint Assessment, and Prioritizing Stations for Hydrogen Production Using Wind Energy: A Case Study
Jul 2021
Publication
While Afghanistan’s power sector is almost completely dependent on fossil fuels it still cannot meet the rising power demand of this country. Deploying a combination of renewable energy systems with hydrogen production as the excess energy storage mechanism could be a sustainable long-term approach for addressing some of the energy problems of Afghanistan. Since Badakhshan is known to have a higher average wind speed than any other Afghan Read More
Green Hydrogen and Electrical Power Production through the Integration of CO2 Capturing from Biogas: Process Optimization and Dynamic Control
Jun 2021
Publication
This study describes the optimization of a modelling process concerning biogas’ use to generate green hydrogen and electrical power. The Aspen Plus simulation tool is used to model the procedure and the approach employed to limit the emissions of gas from the hydrogen production process will be the CO2 capture method. This technique uses slack lime (Ca(OH)2) to absorb CO2 capture since it is readily available. The study analyzes many critica Read More
Proton Exchange Membrane Electrolyzer Modeling for Power Electronics Control: A Short Review
May 2020
Publication
The main purpose of this article is to provide a short review of proton exchange membrane electrolyzer (PEMEL) modeling used for power electronics control. So far three types of PEMEL modeling have been adopted in the literature: resistive load static load (including an equivalent resistance series-connected with a DC voltage generator representing the reversible voltage) and dynamic load (taking into consideration the dynamics both at the anode and the Read More
Performance and Cost Analysis of Hydrogen Production from Steam Reforming and Dehydrogenation of Ethanol
Aug 2020
Publication
Mitigation of carbon dioxide (CO2) emission has been a worldwide concern. Decreasing CO2 emission by converting it into higher value products such as methanol can be a promising way. However hydrogen (H2) cost and availability are one of key barriers to CO2 conversion. Ethanol can be a sustainable source for H2 due to its renewable nature and easy conversion to H2-rich gas mixtures through ethanol steam reforming process. Nevertheless st Read More
Overview of Hydrogen Production Technologies for Fuel Cell Utilization
Jun 2023
Publication
With rapidly depleting fossil fuels and growing environmental alarms due to their usage hydrogen as an energy vector provides a clean and sustainable solution. However the challenge lies in replacing mature fossil fuel technology with efficient and economical hydrogen production. This paper provides a technoeconomic and environmental overview of H2 production technologies. Reforming of fossil fuels is still considered as the backbone of large-s Read More
Maximizing H2 Production from a Combination of Catalytic Partial Oxidation of CH4 and Water Gas Shift Reaction
Jan 2025
Publication
A single-bed and dual-bed catalyst system was studied to maximize H2 production from the combination of partial oxidation of CH4 and water gas shift reaction. In addition the different types of catalysts including Ni Cu Ni-Re and Cu-Re supported on gadolinium-doped ceria (GDC) were investigated under different operating conditions of temperature (400–650 ◦C). Over Ni-based catalysts methane can easily dissociate on a Ni surface to give hydrog Read More
Enhancing Hydrogen Production from Chlorella sp. Biomass by Pre-Hydrolysis with Simultaneous Saccharification and Fermentation (PSSF)
Mar 2019
Publication
Simultaneous saccharification and fermentation (SSF) and pre-hydrolysis with SSF (PSSF) were used to produce hydrogen from the biomass of Chlorella sp. SSF was conducted using an enzyme mixture consisting of 80 filter paper unit (FPU) g-biomass−1 of cellulase 92 U g-biomass−1 of amylase and 120 U g-biomass−1 of glucoamylase at 35 ◦C for 108 h. This yielded 170 mL-H2 g-volatile-solids−1 (VS) with a productivity of 1.6 mL-H2 g-VS−1 h −1 . Pre Read More
Open-Circuit Switch Fault Diagnosis and Accommodation of a Three-Level Interleaved Buck Converter for Electrolyzer Applications
Mar 2023
Publication
This article proposes a novel open-circuit switch fault diagnosis method (FDM) for a three-level interleaved buck converter (TLIBC) in a hydrogen production system based on the water electrolysis process. The control algorithm is suitably modified to ensure the same hydrogen production despite the fault. The TLIBC enables the interfacing of the power source (i.e. low-carbon energy sources) and electrolyzer while driving the hydrogen production of the s Read More
