Special Issue Information

Dear Colleagues,

In the third decade of the 21st century, large amounts of energy are needed to meet the needs of individual residents and large technology companies. Electricity and heat are essential in our homes, vehicles and various industrial processes. Replacing existing fossil energy sources with hydrogen will be the basis for the climate and energy transition of technology and transport companies, as well as the entire local and international community. According to experts, the time has come for hydrogen technologies to be effectively implemented in the various areas mentioned above. In this Special Issue, we encourage you to critically review the technologies currently on the market for the production of hydrogen in renewable energy systems.

Review articles will facilitate the significant decision-making required in the selection of the best technologies for specific applications and will also be the basis for their integration into effective energy and production systems. Another important focus will be the description of current market implementations of individual technologies for the production of low-emission hydrogen from renewable energy sources and their combinations. The analyses and research presented in these articles will enable a comparison of theoretical assumptions related to their functioning with industrial practice. They will enable the optimization of hydrogen production processes using the latest methods and traditional and AI-based algorithms. Furthermore, this Special Issue will focus on innovative technologies for hydrogen production in renewable energy systems. This includes solutions known but not yet used in industrial practice due to high costs, but also those resulting from scientists' discoveries in recent months. The editors encourage you to submit articles and also participate in the article review process.

The topics of interest for publication include, but are not limited to, the following:

  1. Energy production from renewable energy sources and their combinations together with the use of energy storage systems.
  2. Integration and optimization of RES with hydrogen production systems.
  3. Traditional and innovative technologies for hydrogen production together with its preparation and storage.
  4. Modeling the dynamics of energy and hydrogen production.
  5. Methods for the effective processing of measurement data using traditional and AI-based algorithms.
  6. Case studies of practical implementations of hydrogen technologies, along with their scientific description and efficiency assessment.
  7. Modeling and simulation of individual low-emission hydrogen production processes.
  8. Integration and optimization of complex processes.
  9. Development of hydrogen valleys and local communities friendly to hydrogen technologies.
  10. Ecology and economics in the hydrogen economy.

We encourage not only scientists working at universities, research and development institutes, science and technology parks, but also those in research and development centers of technology companies to publish in the Special Issue. Effective cooperation between science and business is highly desirable for the rapid and safe implementation of low-emission technologies in various areas of life and industry.

Low-emission hydrogen generation systems require large amounts of energy from renewable energy sources. This article characterizes the production of low-emission hydrogen, emphasizing its scale and the necessity for its continuity. For hydrogen production defined in this way, it is possible to select the appropriate renewable energy sources. The research part of the article presents a case study of the continuous production of large amounts of hydrogen. Daily production capacities correspond to the demand for the production of industrial chemicals and artificial fertilizers or for fueling a fleet of hydrogen buses. The production was placed in the Lublin region in Poland, where there is a large demand for low-emission hydrogen and where there are favorable conditions for the production of energy from a photovoltaic–wind mix. Statistical and probabilistic analyses were performed related to the generation of power by a photovoltaic system with a peak power of 3.45 MWp and a wind turbine with an identical maximum power. The conducted research confirmed the complementarity and substitutability relationship between one source and another within the energy mix. Then, unsupervised clustering was applied using the k-Means algorithm to divide the state space generated in the power mix. The clustering results were used to perform an operational analysis of the low-emission hydrogen generation system from a renewable energy sources mix. In the analyzed month of April, 25% of the energy generated in the photovoltaic–wind mix came from the photovoltaic system. The low-emission hydrogen generation process was in states (clusters), ensuring that the operation of the electrolyzer with nominal power amounted to 57% of the total operating time in that month. In May, the share of photovoltaics in the generated power was 45%. The low-emission hydrogen generation process was in states, ensuring that the operation of the electrolyzer with nominal power amounted to 43% of the total time in that month. In the remaining states of the hydrogen generation process, the power must be drawn from the energy storage system. The cluster analysis also showed the functioning of the operating states of the power generation process from the mix, which ensures the charging of the energy storage. The conducted research and analyses can be employed in planning and implementing effective climate and energy transformations in large companies using low-emission hydrogen. Full article
