Shipping fuel transition: carbon pricing and hydrogen costs will decide newbuilding choices

Shipping's move away from fossil fuels will stay limited unless carbon pricing rises sharply, according to a new study from GCMD and BCG. The report models 12 fuel pathways and finds that at $380 per tonne CO2, conventional fuels still dominate, with VLSFO and fossil LNG making up 40% of fleet energy by 2050. Only at $700 per tonne do new fuels become competitive, reaching 61% of consumption. Hydrogen cost is the biggest swing factor. If renewable hydrogen falls to $2/kg, e-methanol and e-ammonia could supply 36% of global fleet demand by 2050. The report urges owners to build optionality rather than bet on a single fuel, especially with more than half of 2050's fleet coming from orders placed before 2035. The newbuilding boom, with $3.1 trillion in cash generated since 2021, makes these decisions urgent.

Key takeaway: without a carbon price near $700/tonne, fossil fuels stay dominant. The report basically says the IMO penalty at $380 is too low to move the needle. Owners ordering now need to build in fuel flexibility.

The hydrogen cost assumption is the big swing factor. If green H2 drops to $2/kg, e-methanol and e-ammonia become competitive. But that depends on cheap renewable power and electrolyzer scale. What's the realistic timeline for that?

Carbon pricing is the lever. But $700/tonne by 2050 is a big ask. The report shows how sensitive the fuel mix is to that number. Policy makers need to set a clear trajectory so owners can plan 25 year asset lives.

Interesting that e-methanol and e-ammonia end up at similar cost around $52/GJ. Ammonia is cheaper to produce but storage and bunkering costs kill the advantage. Good to see the full cost breakdown, not just production cost.

The newbuilding boom complicates things. Ships ordered now will still be sailing in 2050. The report says more than half of 2050 fleet comes from orders before 2035. So fuel choices made today lock in emissions for decades.
