Special Issue Information

Dear Colleagues,

The global end of reliance on fossil fuels for power and efforts towards achieving carbon neutrality are driving a clean energy revolution. Renewable energy sources such as wind and solar, which emit little or no greenhouse gases, have achieved remarkable milestones in the transition to low-carbon power systems. However, the high penetration of intermittent and variable renewable energy sources poses many technical challenges to electrical grids such as the issues related to power quality and generation–demand imbalances. Hydrogen energy is one of the leading solutions to absorbing and storing excess renewable generation. As a highly versatile energy carrier, hydrogen can also be applied in many hard-to-decarbonise sectors where electricity might not be suitable for their deep decarbonisation. Therefore, the co-development of renewable energy and hydrogen energy technologies will greatly contribute to the decarbonisation of the whole energy systems.

This Special Issue aims to present and disseminate the innovative research and advanced technologies in all relevant aspects of renewable energy and hydrogen energy. Topics of interest for publication include, but are not limited to, the following:

  • Hydrogen production;
  • Hydrogen storage;
  • Hydrogen transportation;
  • Hydrogen application;
  • Hydrogen fuel cell materials and their preparation;
  • Power system integration;
  • Power system modelling, planning and coordination;
  • Renewable energy forecasting;
  • Integrated energy system;
  • Power and energy conversion;
  • Energy storage and conversion for grid and transportation applications;
  • Energy management for energy storage systems.

Fuel cells, as clean and efficient energy conversion devices, hold great potential for applications in the fields of hydrogen-based transportation and stand-alone power systems. Due to their sensitivity to load parameters, environmental parameters, and gas supply, the performance monitoring and fault diagnosis of fuel cell systems have become crucial research areas. Electrochemical impedance spectroscopy (EIS) is a widely applied analytical method in fuel cell systems. that can provide rich information about dynamic system responses, internal impedance, and transmission characteristics. Currently, EIS detection is primarily implemented by using simple topologies such as boost circuits. However, the injection of excitation signals often results in significant power fluctuations, leading to issues such as uneven temperature distributions within the cell, unstable gas supply, and damage to the proton exchange membrane. To address this issue, this paper proposes a real-time EIS detection technique for a proton exchange membrane fuel cell (PEMFC) system that connects a lithium-ion battery and injects the load voltage perturbation through a triple active bridge (TAB) converter. By applying the small-signal model of the TAB converter and designing a system controller using a decoupling control method, the PEMFC power remains stable after the disturbance injection across the entire frequency range under tests. Furthermore, the lithium-ion battery can instantly track load changes during fluctuations. The proposed EIS detection method can acquire EIS data in real time to monitor the state of the PEMFC. Simulation results validate the effectiveness and accuracy of the proposed method for EIS detection. Full article

This paper provides a systematic visualization of the development, current status and challenges of salt cavern hydrogen storage technology based on the relevant literature from the past five years in the Web of Science Core Collection database. Using VOSviewer (version 1.6.20) and CiteSpace software (advanced version 6.3.R3), this study analyzes the field from a knowledge mapping perspective. The findings reveal that global research hotspots are primarily focused on multi-energy collaboration, integration of renewable energy systems and exploration of commercialization, highlighting the essential role of salt cavern hydrogen storage in driving the energy transition and promoting sustainable development. In China, research mainly concentrates on theoretical innovations and technological optimizations to address complex geological conditions. Despite the rapid growth in the number of Chinese publications, unresolved challenges remain, such as the complexity of layered salt rock, and thermodynamic coupling effects during high-frequency injection and extraction, as well as issues concerning permeability and microbial activity. Moving forward, China’s salt cavern hydrogen storage technology should focus on strengthening engineering practices suited to local geological conditions and enhancing the application of intelligent technologies, thereby facilitating the translation of theoretical research into practical applications.
