Looks like there is a computer malfunction somewhere in that the files are to big to upload to this site. Sorry everyone though I expect some one can help.!!

Hyrodgen fuel storage  :o ...our Australian dingbat Politicians are suggesting we can be the green  Country for the World


Thats probably why they are suggesting the actual storage tanks are not permitted into the [ACT] Canberra....probably for fear of an explosion  >>:-(

Hydrogen is little different to natural or town gas for explosion risk. I expect politicians are relying on a good proportion of the population to be too knee-jerk to realise this.


I appreciate that Hydrogen has a lighter atomic weight and is simpler than the other two, thus slightly more difficult to store, but we hear of gas explosions all the time.


Anyhow this is nautical forum so, I will read the articles. If using conventional engines, there is an issue with hydrolysing the cylinders and pistons making them brittle over time, so an additive needs to be mixed with the hydrogen to reduce/prevent this.

I do not know how many of you fellows are old enough(or young enough) to remember the R N experimenting with Hydrogen Peroxide to power conventional subs. The two subs built for the trials were Excalibur and i think the other Explorer, but I remember the trials were an abject failure. Stories of valves shattering and several fires, until they were both towed away for razor blades.

Interesting wiki article on HMS Explorer (Submarine) and why it was known as HMS Exploder

my only recollection of hydrogen peroxide, was related to torpedo's or a similar fuel that was used for the providing air to generate the power for the torpedo's running, was it not the reason for the Kursk going down?

I used to work with a few Comex guys that did the record depth hydrox saturation diving team back decades ago (LSS, Dive Supervisors etc, not the Divers)  I shudder to think what it was like keeping a mix of hydrogen and oxygen in storage was like.  But that was old days.  Fuel cells are a different animal entirely.

Talking of torpedo fuel, remember once on RMAS Arrochar loading drums of a torpedo fuel sealed in a thick plastic lined steel drums which were sealed in plastic about 1987. The fuel encased like that because it was very carcinogenic it was loaded with a special team with special sensors. Turns out a new weapon was coming in service and i went round the various Armament Depots collecting it before it went to one for special disposal, after we discharged it it still left trace readings in the hold, only thing I knew it was orange in colour. But yes remember in the late 1970's/early 1980's aerial / ship launched short torpedoes were primed by men in ABC suits with breathing sets. Mind you some of the stuff mixed into aircraft fuel and engine fuel have some nasty chemicals put in, know that from my garden, a leaked trail of oil killed my plants out right and you could see a line of dead plants over several gardens.
