Research Progress, Trends, and Current State of Development on PEMFC-New Insights from a Bibliometric Analysis and Characteristics of Two Decades of Research Output
Nov 2022
Publication
The consumption of hydrogen could increase by sixfold in 2050 compared to 2020 levels reaching about 530 Mt. Against this backdrop the proton exchange membrane fuel cell (PEMFC) has been a major research area in the field of energy engineering. Several reviews have been provided in the existing corpus of literature on PEMFC but questions related to their evolutionary nuances and research hotspots remain largely unanswered. To fill this gap the curr Read More
Optimal Hybrid Renewable Energy System: A Comparative Study of Wind/Hydrogen/Fuel-Cell and Wind/Battery Storage
Dec 2020
Publication
This paper performs a technoeconomic comparison of two hybrid renewable energy supplies (HRES) for a specific location in Ghana and suggests the optimal solution in terms of cost energy generation capacity and emissions. (e two HRES considered in this paper were wind/hydrogen/fuel-cell and wind/battery storage respectively. (e necessity of this study was derived from the rise and expansion of hybrid renewable energy supply in a decentralised netw Read More
Techno-economic Viability of Decentralised Solar Photovoltaic-based Green Hydrogen Production for Sustainable Energy Transition in Ghana
Feb 2024
Publication
Transition to a sustainable energy supply is essential for addressing the challenges of climate change and achieving a low-carbon future. Green hydrogen produced from solar photovoltaic (PV) systems presents a promising solution in Ghana where energy demands are increasing rapidly. The levelized cost of hydrogen (LCOH) is considered a critical metric to evaluate hydrogen production techniques cost competitiveness and economic viability. This stud Read More
Evaluating the Economic Viability of Decentralised Solar PV-based Green Hydrogen for Cooking in Ghana
Jul 2024
Publication
Developing countries including Ghana face challenges ensuring access to clean and reliable cooking fuels and technologies. Traditional biomass sources mainly used in most developing countries for cooking contribute to deforestation and indoor air pollution necessitating a shift towards environmentally friendly alternatives. The study’s primary objective is to evaluate the economic viability of using solar PV-based green hydrogen as a sustainable f Read More
Investigation of Hybrid Power-to-hydrogen/Nautral Gas and Hydrogen-to-X System in Cameroon
May 2024
Publication
In Sub-Saharan Africa (SSA) the capacity to generate energy faces significant hurdles. Despite efforts to integrate renewable energy sources and natural gas power plants into the energy portfolio the desired reduction in environmental impact and alleviation of energy poverty remain elusive. Hence exploring a spectrum of hybrid technologies encompassing storage and hydrogen-based solutions is imperative to optimize energy production while mitigatin Read More
Techno-economic Analysis of Green Hydrogen Production and Electric Vehicle Charging Using Redundant Energy on a Solar Photovoltaic Mini-grid
Nov 2024
Publication
The trajectory of the world’s energy use has moved towards the use of renewable energy to increase energy access. Solar energy’s pace of growth as a result of its low cost has resulted in it being used to generate electricity for areas that do not have access to grid electricity. Thus solar photovoltaic mini-grid systems have been deployed in several areas. Over time it has been found that these systems generate a significant amount of redundant energy Read More
