During Gastech, Korean Register (KR) and Daewoo Shipbuilding & Marine Engineering (DSME) signed a Memorandum of Understanding (MOU) to jointly collaborate for developing new propulsion systems capable of handling green fuels including ammonia and hydrogen. The move follows announcements that KR would be jointly developing a liquefied CO2 carrier with DSME.
Ammonia and hydrogen, widely recognized as green alternatives, but are considered to have more sensitive characteristics than commonly used LNG fuels. To be used as a marine fuel, extra technical requirements need to be addressed.
These include the toxicity of ammonia, hydrogen embrittlement, cryogenic conditions equivalent to -253 ° C, diffusion characteristics, as well as ensuring the same level of safety as existing ships.
This joint research agreement between the two parties will build on the unique strengths and accumulated technology of each company.
DSME aims to commercialize ammonia-powered container ships by 2025 based on its advanced technology, and is at an advanced stage in developing eco-friendly fuel technologies, including low-carbon ammonia carriers and liquefied CO2 carriers.
KR has also been actively seeking better options for decarbonization pathways. As well as publishing guidelines for ammonia-fueled ships, the classification society is developing its own hydrogen-powered ship rules and is working on enhanced decarbonization initiatives to ensure ship safety and a greener future.
