Sounds like LPG/Diesel, but for Hydrogen

That makes sense. The 2 biggest challenges with Hydrogen in an ICE environment have always been the production of NOx and the fact it has such a low effective octane rating the only engine it doesn't tend to detonate to pieces in short order is a Wankel. This sounds like an ideal compromise, because NOx in a Diesel is already a mostly solved issue, and knock is something they're built to both control and tolerate. It appears the use of Diesel with the Hydrogen helps control the knock, and the idea of it being able to revert entirely to Diesel if Hydrogen is absent means Hydrogen will only get used if it's actually cheaper in real terms.

Sounds like a good idea to me.

The question I want answered is how do you store the hydrogen on farm and how do we refuel tractors out in the paddocks, as we do now?
No one can answer this for me. I am told there will be a way. Sounds like jumping out of an aeroplane hoping someone will pass you a parachute on the way down.

I think the key to this is this particular technology already has the parachute built in. It'll run like a regular diesel on regular diesel. It's a bit of a "build it and they will come" thing. There's no point developing the hydrogen infrastructure because there's currently no way to use it. Doing it this way, you have a device that runs on regular diesel. It just has the ability to run cheaper on Hydrogen when someone figures out how to get it to you in a manner you can use.

Without having a viable use case, nobody in their right mind is going to dedicate resources to the supply chain. "Hey, we can getcha plenty of cheap hydrogen" is not much use when the only thing you can do with it is fill a zeppelin.

Its a huge issue Lindsay. Hydrogen specific storage tech is developing rapidly. PV1 a shipping design/engineering company has some nifty designs at low pressures not that much more than my diving kit at a SHIP sized scale[biggrin].

Storage tanks type 1 to type 4 stores are of most interest for me (in a investment mode) "There are four standard types of cylinders that are used for hydrogen storage:
Type I—all-metal cylinders,
Type II—all-metal hoop-wrapped composite cylinders,
Type III—fully wrapped composite cylinders with metallic liners (e.g., Al-6061), and
Type IV—fully wrapped composite cylinders with nonload bearing nonmetallic "


The last is very interesting as it may be cheaper, lighter, stonger and faster to make.

A EU company type 4 are of course as first of $$$$$$$$$$$ The technology is not that different to our oxy/acetylene which are often borrowed/hired from BOC?

Price wise buying hydrogen which used to costs a few $$ via steam methane reforming is about to see both large and small scale onsite production

It might be this storage pod cast on storage that covered the tank types very well. Unsupported browser (https://open.spotify.com/episode/2xeQ0rnZbVRUIGu4sQnXIN'si=e516f72fcc114126)


It might have been another one - excuse me if I missed the storage tanks!

Edit- sorry it was "Hexagon Purus | Hydrogen high-pressure Type 4 cylinders (https://hexagonpurus.com/our-solutions/hydrogen-systems/hydrogen-type-4-cylinders)"

The Hydrogen trains and trucks coming on stream now will see this type of tech follow Moores law I think!

What I have read recently was that a diesel engine will run on hydrogen, however it will reduce the power output when that engine running on it. If you have to bump up the power, you will increase the pollutants from said engine. Not sure where I read it because it is a concern to many people and as we store about 17,000 litres
it is a concern for us.
