Hydrogen's interaction with polymers and metals in infrastructure and storage systems poses a significant challenge that needs to be addressed. Understanding the impact of hydrogen on these materials is crucial to ensure the development of robust hydrogen storage infrastructure. Polymers and metals can undergo degradation, embrittlement, or other structural changes when exposed to hydrogen. These effects can compromise the integrity and performance of the infrastructure and storage systems, leading to safety risks and reduced operational efficiency. Therefore, it is essential to gain a comprehensive understanding of these impacts to design materials and systems that can withstand hydrogen exposure effectively. Developing a thorough comprehension of the effects of hydrogen on polymers and metals requires extensive research and testing. This involves studying the mechanisms of hydrogen-induced degradation, such as hydrogen embrittlement and hydrogen-induced cracking. It also requires evaluating the compatibility of various materials with hydrogen and identifying potential vulnerabilities or limitations. By conducting comprehensive investigations, researchers and engineers can develop strategies to mitigate the negative impacts of hydrogen on infrastructure and storage systems, ensuring their long-term durability and reliability. Furthermore, understanding the impact of hydrogen on materials facilitates the design of hydrogen storage infrastructure that is resilient and meets safety standards. This knowledge enables the selection or development of appropriate materials and coatings that can withstand the challenges associated with hydrogen exposure. It also informs the design of storage systems to minimize the risk of leaks, ensure structural integrity, and optimize storage capacity. By addressing the hydrogen-material interaction, robust and safe hydrogen storage infrastructure can be established, promoting the widespread adoption of hydrogen as a clean and sustainable energy carrier.
