The article delves into the evolving role of hydrogen in the maritime industry as part of the sector's transition towards decarbonisation and green technology. Mr. Darr, a key figure in the industry, discusses the potential of hydrogen both as a marine fuel and as a critical fuel stock for various synthetic forms like methanol and green ammonia. While acknowledging the challenges related to the volume of green hydrogen needed and the current gaps in production, there is a clear optimism about the industry's ability to meet the 2050 net-zero target. In addition to exploring hydrogen's direct applications, the article also sheds light on the technological innovations being pursued, such as converting ammonia into hydrogen using a cracker, and the importance of a global regulatory framework to drive the energy transition forward. Mr. Darr emphasizes the necessity for energy providers to step up and play a significant role in producing the required molecules to support these green initiatives. Furthermore, the article touches on the need for industry players to remain creative, open-minded, and adaptable to future developments, stressing the importance of not fixating on current solutions but being prepared to pivot based on evolving technologies and requirements. The discussion also extends to the importance of a collaborative approach between industry stakeholders and governments to establish effective regulatory frameworks and fuel standards that can facilitate a smoother transition towards sustainable practices in maritime operations.
