The automatice speed variable volume control on many cars now may suggest this is a well known issue[bigrolf]
Hunting big BANG is ok with me as well. A Bow is almost silent and my mates who do that seldom return the the gun powered sticks[bigwhistle] I am not good enough sadly.
Some hydrogen use is not so quiet of course "Hydrogen -- a light and extremely powerful rocket propellant NASA"
That use will satisfy most of our explosive speed needs[biggrin] Of interest is plans to make hydrogen for rocket fuel and Oxygen on Mars Researchers Develop Hydrogen and Oxygen Harvesting System for Use on Mars | Sci.News
Got to love science[thumbsupbig] Clearly distances are relative of course. To Mars and back is a long way. Around Australia a few times on land would do it for me! I have done the wet outside a few times [biggrin]
We are seeing change of course. Time frame is the real questions.
Have a great day
AFR 20/12/22
An Australian-developed technology to convert ammonia into green hydrogen is being trialled in the United Kingdom, with hopes the Fortescue Future Industries-backed method will help turbocharge the uptake of hydrogen as a clean energy source, especially for fuel cells.
While Andrew Forrest’s FFI signed a $20 million partnership with CSIRO in 2018 to develop the ammonia cracking prototype, Siemens Energy has announced a $6.5 million trial of the new Metal Membrane Technology (MMT) in Newcastle in the UK.
AFR is a month old or older perhaps? I missed it
Siemens Energy, FFI and GeoPura developing prototype ammonia cracker to produce hydrogen - Green Car Congress
"A Siemens Energy-led consortium has begun work in Newcastle, UK on a new £3.5 million (US$4.24 million) ammonia cracker prototype designed to produce green hydrogen at industrial scale. The prototype will use ammonia to deliver 200kg of hydrogen a day—enough to power around 5-10 hydrogen fuel cell-electric buses.The ammonia cracker system will provide the potential to produce green hydrogen at scale, wherever and whenever it is needed. The system will be designed to deliver high-purity hydrogen, suitable for PEM fuel cell use, using FFI’s Metal Membrane Technology (MMT) purification process. The MMT process developed by FFI and Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organization (CSIRO) (earlier post, earlier post) is key to producing high-purity hydrogen from the ammonia cracking process. It selectively filters the hydrogen while blocking other gases, allowing it to be used as a fuel and converted as needed, at the time of re-fueling."
" The UK Government estimates that hydrogen could make up to one third of the UK’s energy mix by 2050 but there are challenges with hydrogen storage and transport that need to be addressed to make this viable. The ammonia cracker prototype aims to help tackle these challenges.
Siemens Energy and FFI are providing engineering expertise and innovative technical solutions. GeoPura will provide onsite management, and as the off-taker will be taking the hydrogen product from the prototype ammonia cracker system for use in their fuel cell power generation technology. "
That Siemens in now doing some of the testing of this is great. Hazer plants may have a lot of hydrogen to shift. PV1 Hydrogen carriers new yet to be built ships and The metal membrane technology process cracking Ammonia is according to the CSIRO "in its final phase of Development "
Perfect timing for a business about be producing 1000 tonnes per annum from 2023
The cost for the metal membrane technology testing by CSIRO, Siemens , BOC, Toyota and Hyundai looks incredibly cheap! If the plant running costs cracking Ammonia to Hydrogen are efficient the options it provides are very welcome.
CSIRO metal membrane technology reconverts ammonia to hydrogen in a two-stage process:
- firstly, a ruthenium catalyst cracks ammonia into its constituent elements, nitrogen and hydrogen.
- secondly, a vanadium-based metal membrane separates hydrogen from the other elements.
Note1 "Ruthenium is one of the rarest metals on Earth."
Note2 "Vanadium is the fifth most abundant transition metal in the earth's crust, often found with titanium and iron in their ores, and significant concentrations are found in certain coal and oil deposits, such as crude and shale oils."
Have a great day
Bit surprised the Oz research that H and O separation by electrolysis can be increased 14 fold by using HF sound waves hasn't been mentioned,,,,,,,,,,,,,, by anyone in this thread.
Was on RN about 10 days ago.

Below is a very interesting video on the production of Toyota Mirai.
(4) Toyota Fuel Cell PRODUCTION 🇯🇵 HYDROGEN Car Factory (Japan) - YouTube
Usual sort of factory with typical Toyota attention to detail ( not present when they designed air filters sarc.)
I have a few questions
1 is there any boot space at all?
2 What happens to "boil off hydrogen? ( BMW prohibits parking in a garage in case it vents off and finds an ignition source)
The front unit looks very very complex. Hope never to hit anything.
How much does it weigh?
How much does it cost to produce? I have been in many car plants and have never seen such a leisurely pace of production.
Regards PhilipA
Boil off is a issue in Natural gas ships as it is/will be with hydrogen ships Philip The nice company I have a few shares in suggests rather than venting and burning as happens in LNG and some gasses, using it to fuel the ships is a better solution?Quote:

Cannot help you with boot space. That's a bit Changeable[bigrolf]
The Mirai fuel cell is just one of many of course. I would love the mass prodution to start ASAP. The grumbles about the fumes by the ski. Ski tubes needs a option to allow the retirement of my boat motor ASAP. I could grumble about the cost of fuel but the Disco towing the boat cost me a lot more[bigwhistle]
160kph Chinese train and over 1000km for "On Thursday, 15 September 2022, the Alstom Coradia iLint, the world's first hydrogen train successfully traveled 1,175 km without refueling its hydrogen tank. "
Some days it feels its getting closer [thumbsupbig]
