Don't forget that technology is rapidly advancing to allow green amonia to be used in existing diesel engines, allowing retrofit. MAHLE Powertrain AFC Energy University of Nottingham are currently having very successful results cracking some of the amonia into hydrogen, then injecting it alongside the amonia to allow combustion in diesel engines. Trial should be completed around March 2025. This will totally transform the shipping insldustry allowing vessels to be retrofitted to allow them to run on green amonia.

Hey there, Hydrogen Insight team 👋 Great to see a 30% surge in orders for hydrogen-fueled ships in 2024! This highlights the maritime sector’s growing commitment to decarbonization and showcases hydrogen’s pivotal role in shaping sustainable shipping. Speaking of #hydrogen innovations, don’t miss the 𝟑𝐫𝐝 𝐈𝐧𝐝𝐨𝐧𝐞𝐬𝐢𝐚 𝐈𝐧𝐭𝐞𝐫𝐧𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐇𝐲𝐝𝐫𝐨𝐠𝐞𝐧 𝐒𝐮𝐦𝐦𝐢𝐭 𝟐𝟎𝟐𝟓, where the future of clean maritime transport will take center stage. 🚀 🗓️ July 23–24, 2025 📍 Jakarta Convention Center Check out www.indonesia-ihs.com for details. Let’s sail toward a greener future together! 😉

Truth is, LNG is the big-time winner when it comes to alternative shipping fuel. And this because it is a solid compliance alternative to large shipping fleet owners exposed to FuelEU regulations, setting them up for success until 31/Dec/2039, at least (and possibly beyond that with uptake of bio LNG). DNV's alternative fuel tracker (link in comments) has only 33 ammonia-powered ships on order - which corresponds to only 0.47% of the total on order across conventional and alternative fuel ship types. The potential demand of this order book to only ~600 ktpa NH3 by 2033 - not enough to fully subscribe a single at-scale green or low carbon ammonia project! At the same time, LNG-powered ships on order are at 1,273 most of which distributed across containerships (452), car carriers (208), crude tankers (126) and chemical carriers (116). Again, according to IMO's actual fuel consumption data, the potential demand across these ship types sits at ~8 ktpa LNG per year per ship, if indeed they are ever to run 100% on ammonia. This translates to a potential demand to ~8-10 mtpa LNG by 2033 - not a small amount and around ~1.8x what Germany as a whole imported as LNG back in 2023!
