Literature Review of Hydrogen Energy Systems and Renewable Energy Sources

Abstract

The role of hydrogen as a clean energy source is a promising but also a contentious issue. The global energy production is currently characterized by an unprecedented shift to renewable energy sources (RES) and their technologies. However, the local and environmental benefits of such RES-based technologies show a wide variety of technological maturity, with a common mismatch to local RES stocks and actual utilization levels of RES exploitation. In this literature review, the collected documents taken from the Scopus database using relevant keywords have been organized in homogeneous clusters, and are accompanied by the registration of the relevant studies in the form of one figure and one table. In the second part of this review, selected representations of typical hydrogen energy system (HES) installations in realistic in-field applications have been developed. Finally, the main concerns, challenges and future prospects of HES against a multi-parametric level of contributing determinants have been critically approached and creatively discussed. In addition, key aspects and considerations of the HES-RES convergence are concluded.

A Comparative Study on Discrepancies in Residential Building Energy Performance Certification in a Mediterranean Context

“…The majority of different technologies and types of energy sources have contributed to this situation [19,20], with the choice of energy sources being significantly influenced by political and economic factors [21,22]. The dual substitution policy has been effective in promoting the transition to cleaner heating, with income, energy costs, and education playing key roles [23,24].…”

A Review of the Role of Hydrogen in the Heat Decarbonization of Future Energy Systems: Insights and Perspectives

“…The integration of hydrogen technologies with existing renewable energy resources, such as solar and wind, demonstrates its potential to emerge as a vital energy ecosystem, offering solutions for energy production, storage distribution, and utilization. Additionally, literature reviews on hydrogen energy systems provide insights into the challenges, prospects, and convergence with renewable energy sources (RESs), shedding light on the critical role of hydrogen in the transition to sustainable energy economies [8]. Different aspects of available technologies for utilizing hydrogen as an energy carrier in various countries such as the United Kingdom (UK), Germany, the United States, Norway, and Australia are demonstrated in [9].…”
