Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue on "Advancements and Innovations in Hydrogen Energy" in the open access journal Applied Sciences. This Special Issue aims to bring together cutting-edge research and innovative developments in the field of hydrogen energy, showcasing the latest advancements and their potential applications.

Hydrogen energy represents a pivotal area of research and development in the quest for sustainable and renewable energy sources. With the growing urgency to reduce carbon emissions and transition to cleaner energy systems, hydrogen has emerged as a key player due to its high energy content and environmentally friendly properties. This Special Issue seeks to explore the full spectrum of hydrogen energy research, from production and storage to distribution and utilization.

Topics of interest include, but are not limited to:

  • Advanced methods for hydrogen production, including electrolysis, thermolysis, and photolysis.;
  • Innovative hydrogen storage solutions, such as solid-state storage, liquid hydrogen, and advanced materials;
  • Hydrogen fuel cells and their applications in transportation, stationary power, and portable devices;
  • Integration of hydrogen energy systems with renewable energy sources;
  • Advances in hydrogen infrastructure, including distribution networks and refueling stations;
  • Emerging technologies and materials for hydrogen energy;
  • Applications of AI and machine learning for optimizing hydrogen production processes and systems;
  • Predictive analytics for demand forecasting and supply chain management in hydrogen networks;
  • Use of AI in modeling and simulation of hydrogen energy systems.

We invite researchers, scholars, and industry experts to contribute original research articles, reviews, and case studies that address these and related topics. Your contributions will help drive forward the understanding and application of hydrogen energy technologies, fostering a more sustainable and energy-efficient future.

Sincerely,

Dr. Somtochukwu Godfrey Nnabuife

The integration of wind and solar energy with green hydrogen technologies represents an innovative approach toward achieving sustainable energy solutions. This review examines state-of-the-art strategies for synthesizing renewable energy sources, aimed at improving the efficiency of hydrogen (H2) generation, storage, and utilization. The complementary characteristics of solar and wind energy, where solar power typically peaks during daylight hours while wind energy becomes more accessible at night or during overcast conditions, facilitate more reliable and stable hydrogen production. Quantitatively, hybrid systems can realize a reduction in the levelized cost of hydrogen (LCOH) ranging from EUR 3.5 to EUR 8.9 per kilogram, thereby maximizing the use of renewable resources but also minimizing the overall H2 production and infrastructure costs. Furthermore, advancements such as enhanced electrolysis technologies, with overall efficiencies rising from 6% in 2008 to over 20% in the near future, illustrate significant progress in this domain. The review also addresses operational challenges, including intermittency and scalability, and introduces system topologies that enhance both efficiency and performance. However, it is essential to consider these challenges carefully, because they can significantly impact the overall effectiveness of hydrogen production systems. By providing a comprehensive assessment of these hybrid systems (which are gaining traction), this study highlights their potential to address the increasing global energy demands. However, it also aims to support the transition toward a carbon-neutral future. This potential is significant, because it aligns with both environmental goals and energy requirements. Although challenges remain, the promise of these systems is evident. Full article
