Of all the proposed uses of hydrogen in transportation, shipping makes the most sense.

From Riviera Maritime, November 8:
The LNG dual-fuel box ships will be ammonia ready and able to operate on biomethane, while reports say Hapag-Lloyd will acquire shipmanager Hamburger Lloyd
Hapag-Lloyd has signed contracts with two Chinese shipyards for 24 new container ships, representing a combined capacity of 312,000 TEU and involve a total investment volume of around US$4Bn. Financing of US$3Bn has already been committed.
Of these, 12 newbuildings – each with a capacity of 16,800 TEU – will be built by Yangzijiang Shipbuilding Group to expand the capacity of current services. An additional 12 ships, each with a capacity of 9,200 TEU, have been ordered from New Times Shipbuilding Company Ltd to replace older units in the Hapag-Lloyd fleet.
All the newbuildings will be equipped with state-of-the-art low-emissions high-pressure liquefied gas dual-fuel engines. In addition, these vessels can be operated using biomethane, which can reduce CO2e emissions by up to 95% compared with conventional propulsion systems. The new ships will also be ammonia ready. Hapag-Lloyd will take delivery of the new vessels between 2027 and 2029....
