How much do you know about Hydrogen?

I think its measured in Tonnes of fuel [thumbsupbig]. I was going to ask some mates who are in the right area. My top deck type rating is funny as SONAR room was in the guts of the ship and Diving was often far below the engineering spaces [bigrolf]

Found a sort of science answer for you
"A hulking Arleigh Burke–class destroyer might typically burn a minimum of about 24 barrels (1,000 gallons) of fuel per hour"

The ship I mentioned was a Charlies F Adams class DDG (3,277 tons standard 4,526 full load)

The Arleigh Burke–class destroyer is displacement ranging from 8,300 to 9,700 tons. Thus we might be less than 1000 gallons per hour IF not speeding[biggrin][biggrin][biggrin]

FYI: What Kind Of Gas Mileage Can You Get From A Naval Warship?

Interesting. Do you know how far a destroyer can travel in an hour?

According to Wikipedia around 56KM [emoji6]

Arleigh Burke-class destroyer - Wikipedia

Wow roughly 7279lt/100km for a destroyer! Assuming $1.799/litre for diesel, that’s $13,094.92/100km or $130.95/km.

Retail price for diesel in the USA is just over $1.00 per litre and I’m sure the Navy don’t pay retail. [emoji6]

Most of the big aircraft carriers,etc,use nuclear power.

I do for several types. Johns right yet some information is not really always correct. 100% power for example might be the safe zone[bigwhistle][bigwhistle][bigwhistle]

The Danger Zone

A US navy DDG of the same type I love pushed it a bit + was moving very well above speed records until it blew up a boiler or two [biggrin]

Back to hydrogen to be boring [biggrin]


A Kiwi company FABRUM using a very cool storage and nifty "Membrane-Free Electrolyser™ (MFE) with cryogenic separation to deliver pure hydrogen and pure oxygen as separate gases" from Our Technology | CPH2Is very interesting any where spare cheap power is available perhaps.

Tasmania was in the News with possible off take agreements for its c02 free hydrogen.

Reading about tug boats, trucks, tractors and more powered by ammonia via a large investment fund (AP Ventures) about Amogy - Link below


Merks and others trying Ammonia for shipping I understand as well. [biggrin]

time line was tight!!


July— Successfully engineered the first-ever ammonia-powered emission-free drone flight at a 5kW scale

May— Successfully demonstrated a 100kW powerpack in a tractor, scaling 20x in less than a year

January—Presented the world’s first ammonia-powered semi-truck by scaling the powerpack to 300kW
Late 2023— Targeting to scale the powerpack to 1MW for a tugboat demonstration, initiating the commercialization of Amogy technology


Home - Amogy


Maersk is the bigget shipping company I think, It also neglects to say it will be using Hydrogen to make the ammonia

"With A.P. Moller - Maersk as one of the collaborators, Copenhagen Infrastructure Partners (CIP) has unveiled plans for the establishment of Europe’s largest production facility of green ammonia. A.P. Moller - Maersk is on a quest to find the marine fuels of the future with green ammonia being one of three preferred fuel types.

The Power-to-X facility located in Esbjerg on the Danish west coast will convert power from wind turbines to green ammonia. The green ammonia produced at the facility can be utilized by the agricultural sector as green fertilizer and by the shipping industry as a truly sustainable green fuel.

A.P. Moller - Maersk along with Danish companies Arla, Danish Crown, DLG and DFDS has signed a memorandum of understanding, committing to work towards realizing the establishment of the facility as well as supporting the off-take of the green ammonia from the facility once it is ready to be delivered to the market."

"Jemena said it had identified enough potential sources of biomethane – including wastewater plants, landfill, food, agricultural, and crop waste – to generate about 30 petajoules of biomethane each year" link to story which is not on hydrogen yet [biggrin][biggrin]

Just listened to a presentation by the cool poo farm hydrogen project in WA. The Cost of hydrogen via that process will be Seven times cheaper than Electrolysis !

The 100Mtpa plant in WA and 3 500 Mtpa in Japan, Canada and France suggesting the start of this which if 10 plants only covers 1% of existing dirty hydrogen replacement is going to be big.


The presentation may be on Hazer Groups web site in a few days. I am biased of course. The link to NSW 30 ptj of biomeathane is a thought bubble only!

Are you bias because you create lots of methane each day? [emoji4]
