The article discusses the increasing focus in the global shipping industry on transitioning towards decarbonization, highlighting hydrogen-powered vessels as a prominent solution to meet emission reduction targets. Specifically, it mentions the International Maritime Organization (IMO) goal of reducing emissions by 50% by 2050 and how hydrogen aligns with international regulations such as the IMO's greenhouse gas reduction strategy and the MARPOL Convention. The article acknowledges the regulatory support for hydrogen technologies and the advancements in fuel cell technology. However, it also outlines existing challenges in areas such as hydrogen storage, fuel cell integration, and operational safety. Currently, high-pressure gaseous hydrogen storage is deemed the most feasible option, despite spatial and safety limitations. The article also mentions alternative storage methods like cryogenic liquid hydrogen, organic liquid hydrogen carriers, and metal hydride storage, which hold promise but face technical barriers. The key to overcoming these challenges lies in continued innovation in vessel design, fuel cell technology, and storage systems, complemented by the establishment of comprehensive safety standards and regulations. Commercializing hydrogen-powered vessels is crucial for the decarbonization of global shipping and the achievement of climate objectives. The article emphasizes the significance of hydrogen in meeting international emission reduction targets and underlines the necessity of aligning with regulatory frameworks to propel sustainability in the maritime industry.
