Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue on Advances in Hydrogen and Energy Transition. As known, hydrogen has emerged as a promising energy carrier. It is essential for decarbonizing heat and power across different sectors such as buildings, transportation, industry, logistics, and more. Hydrogen-based solutions can play a crucial role in mitigating greenhouse gas emissions and fostering a sustainable future.

This Special Issue invites contributions from researchers and practitioners in academia, industry, and the government actively working on hydrogen-related topics. We welcome original research articles, review papers, and case studies related to, but not limited to, the following topics:

  • Hydrogen production technologies;
  • Hydrogen storage and transportation;
  • Integration of renewable energy sources into hydrogen systems;
  • Hydrogen utilization in buildings and district heating systems;
  • Hydrogen as a fuel for transportation (vehicles, refueling infrastructure, et cetera.);
  • Integration of hydrogen in energy systems;
  • Life cycle analysis and sustainability of hydrogen systems;
  • Policy, regulatory, and market issues related to hydrogen adoption;
  • Economic and business models for hydrogen-based solutions.

This Special Issue will provide a platform for exchanging knowledge and ideas among researchers and practitioners in the hydrogen and energy transition field. We look forward to receiving your contributions and thank you for your interest in this Special Issue.

This paper offers a set of comprehensive guidelines aimed at facilitating the widespread adoption of hydrogen in the industrial hard-to-abate sectors. The authors begin by conducting a detailed analysis of these sectors, providing an overview of their unique characteristics and challenges. This paper delves into specific elements related to hydrogen technologies, shedding light on their potential applications, and discussing feasible implementation strategies. By exploring the strengths and limitations of each technology, this paper offers valuable insights into its suitability for specific applications. Finally, through a specific analysis focused on the steel sector, the authors provide in-depth information on the potential benefits and challenges associated with hydrogen adoption in this context. By emphasizing the steel sector as a focal point, the authors contribute to a more nuanced understanding of hydrogen’s role in decarbonizing industrial processes and inspire further exploration of its applications in other challenging sectors.

Assessing the Feasibility of Hydrogen and Electric Buses for Urban Public Transportation using Rooftop Integrated Photovoltaic Energy in Cuenca Ecuador

A main restriction of renewables from intermittent sources is the mismatch between energy resource availability and energy requirements, especially when extensive power plants are producing at their highest potential causing huge energy surpluses. In these cases, excess power must be stored or curtailed. One alternative is increasing urban solar potential which could be integrated to feed electric buses directly or alternatively through hydrogen (H2) as an energy vector. H2 from renewable electricity can be stored and used directly or through fuel cells. This study aims to determine the H2 capability that could be achieved when integrating large-scale photovoltaic (PV) generation in urban areas. This analysis was carried out by determining the PV energy potentially generated by installing PV in Cuenca City downtown (Ecuador). Cuenca is in the process of adopting renewal of the public transport vehicle fleet, introducing a new model with an electric tram main network combined with “clean type buses”. The conventional diesel urban transport could be replaced, establishing a required vehicle fleet of 475 buses spread over 29 routes, emitting 112 tons of CO2 and burning 11,175 gallons of diesel daily. Between the main findings, we concluded that the electricity that could be produced in the total roof area exceeds the actual demand in the study area by 5.5 times. Taking into account the energy surplus, it was determined that the available PV power will cover from 97% to 127% of the total demand necessary to mobilize the city bus fleet. The novelty of this work is the proposal of a combined methodology to find the potential to feed urban transport with urban solar power in cities, close to the equatorial line. Full article

This paper aims to perform a systematic review, with a bibliometric approach, of the techno-economic evaluation studies of hydrogen production. To achieve this objective, a comprehensive outline of hydrogen production processes from fossil and renewable sources is presented. The results reveal that electrolysis, classified as water splitting, is the most investigated process in the literature since it contributes to a reduction in greenhouse gas emissions and presents other advantages, such as maturity and applicability, energy efficiency, flexibility, and energy storage potential. In addition, the processes of gasification, classified as thermochemical, and steam reforming, classified as catalytic reforming, are worth mentioning. Regarding the biological category, there is a balance between research on photo fermentation and dark fermentation. The literature on the techno-economic evaluation of hydrogen production highlights significant gaps, including a scarcity of comprehensive studies, a lack of emphasis on commercial viability, an absence of sensitivity analysis, and the need for comparative analyses between production technologies.
