OT: ammonia powered ship

[Andy Burns]

Ammonia for ships has been discussed here before, lower energy density
compared to fuel oil.

<https://www.gov.uk/government/news/worlds-first-dual-fuel-ammonia-powered-vessel-arrives-in-the-uk>

Can anyone make sense of this wording?

"The vessel is the first of its kind,
powered by a four-stroke engine,
two of which are capable of being fuelled
by ammonia and diesel."

At <https://zero.fortescue.com/en/case-studies/green-pioneer> it states:
"Technological Breakthrough: Two of the four engines converted to
operate on a dual-fuel ammonia and diesel mix, with conversion completed
at Seatrium Shipyard’s Benoi facility."

Perhaps that got garbled in the gov.uk statement. There's a surprise...

Seems they have looked at the problem of NOx emissions, particularly N2O.

Yup, journalist read something technical, and got the wrong end of the
stick!

AI autocorrect? Sees the number "4" in close association with "engine"?
