The article discusses the ongoing efforts within the maritime industry to address the global warming crisis by reducing greenhouse gas emissions. With the introduction of FuelEU Maritime, vessels are now required to decrease the carbon intensity of their fuel use, ultimately aiming for an 80% reduction by 2050. Clean hydrogen is highlighted as a potential solution to achieve these targets, especially for inland navigation vessels and short-sea ships. The article also mentions the feasibility of using hydrogen as a fuel source for larger vessels like cruise ships while at berth. However, several challenges lie ahead for hydrogen adoption, including safety concerns, storage solutions, availability of green hydrogen, and the need for supportive regulatory frameworks. Overall, the sentiment towards hydrogen in the maritime industry is positive, with a recognition of its potential to significantly reduce carbon emissions once these challenges are addressed.
