Special Issue Information

Dear Colleagues,

The world's energy dynamic is shifting dramatically as countries work to slash carbon emissions and pivot towards more sustainable power sources. Hydrogen is emerging as a pivotal player. As an abundant and versatile energy carrier, hydrogen offers solutions to the variability inherent to renewables such as solar and wind, ensuring steady energy flow. However, hydrogen's low volumetric density and potential explosivity pose challenges, especially concerning storage and transportation.

This Special Issue explores the challenges and innovations of hydrogen energy storage. We are inviting submissions on the following topics:

  1. Materials Science: Advancements enhancing hydrogen production, storage, and conversion. This includes metal hydrides, chemical storage solutions, and advanced porous materials.
  2. Storage Techniques: Innovative storage methods, from compressed gas and liquid hydrogen to solid-state and underground options. Key focus: safety, durability, efficiency.
  3. Technological Insights: Integration of hydrogen storage with renewables, grid management, and real-world usage. Articles should offer insights into system design and optimization.
  4. Economic and Environmental: Analyses of hydrogen storage's economic feasibility and environmental impact, considering the full hydrogen lifecycle.
  5. Regulation and Market Dynamics: Exploration of how policy, regulation, and market trends influence hydrogen energy storage's trajectory and its stakeholders.
  6. Future Outlook: Predictions and insights into hydrogen storage's future, covering potential breakthroughs and anticipated challenges.

This research investigates the potential of using bedded salt formations for underground hydrogen storage. We present a novel artificial intelligence framework that employs spatial data analysis and multi-criteria decision-making to pinpoint the most appropriate sites for hydrogen storage in salt caverns. This methodology incorporates a comprehensive platform enhanced by a deep learning algorithm, specifically a convolutional neural network (CNN), to generate suitability maps for rock salt deposits for hydrogen storage. The efficacy of the CNN algorithm was assessed using metrics such as Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Square Error (RMSE), and the Correlation Coefficient (R2), with comparisons made to a real-world dataset. The CNN model showed outstanding performance, with an R2 of 0.96, MSE of 1.97, MAE of 1.003, and RMSE of 1.4. This novel approach leverages advanced deep learning techniques to offer a unique framework for assessing the viability of underground hydrogen storage. It presents a significant advancement in the field, offering valuable insights for a wide range of stakeholders and facilitating the identification of ideal sites for hydrogen storage facilities, thereby supporting informed decision-making and sustainable energy infrastructure development.
