I really can not see them using Hydrogen to generate electricity, especially when they are using electricity to get the hydrogen in the first place, for the most part and the whole round trip is costly, energy wise.  I can't even see them using H2 as a storage medium for excess power production short term until the evening duck bill hits, or the cloudy week rolls in.  There are other ways to store energy that are much safer and cheaper.

Even then, power plants, shit leaks, if you ever worked at a gas fired plant, you smell it all over the place, it's the nature of the  beast.  Hydrogen is so FKN dangerous, ignites SO easy and you can't see the flames really when it burns, unlike NG where you can see the flame pretty easy.

Hydrogen needs special materials too, the molecule is so small it seeps out very easy AND it is very hard on steel / steel alloys.  They get brittle and wear out much faster.

Anytime I had to work on the H2 system, even for minor stuff like replacing a gauge or something, id always take the IR gun with me to check for fires before I touched a thing.  Nothing will wake you up in the morning faster than going to turn a lever to open up the cock for a pressure gauge and feeling the hair on your arm singe because there was a tiny leak and it ignited itself coming out that pinhole leak from the friction.  YES the stuff really is that unstable.

Today we have more hydrogen highway news. This time it compares H2 busses with all electric busses. It would appear that the Santa Cruz bus transit plan is to go all in on H2 and just hope it works out. Page 1.

Well, for rapid turn around it would make a bit more sense, you can refill the H2 in about 15 minutes .vs. an hour or so to charge the battery.  Especially for a bus, which in theory, may be running 24 hours a day.  Going to be expensive though.  Why not just go with propane, or LNG which although is less energy dense, at least there's sort of an infrastructure there already.  A bus does not have to go  0 to 60 in 3.2 seconds.

I can appreciate you scanning in the newspaper as opposed to posting a link with lots of advertising and who knows what else behind the scenes.  Page 2 is just too tiny in this instance.

That is odd. I don't have any problem reading page 2 and my eyesight sucks.    Did you click on the picture to enlarge the thumbnail in my post?

[Fran K]

Yes I clicked on it, opened it in new window I did somelthing to download to my download folder as a 342kb file opened it in photos which is the default picture opening file.  it is about 830x635 pixels.  I guess now if I open it in paint and do zoom in it is readable but still better to type in the author and a few words in the title into seardh.

I have been hearing and reading about fuel cell research for years.  Sure some of it was used during the manned moon missions but I am not thinking that far back.  Kind of local as in state level like what you post about state for you.  I have not heard about vehicles run on compressed air for quite a whild so things might be looking up.  If the green electricity and used it to pump water up and then used it to run a turbine to recharge batteries later how would that compare to the effeciency of this?  Are there any purity issues with hydrogen.  I think that is a problem with gasoline fuel cell.   Am I dreaming, something about a fuel cell Corvette (gasoline) that was when the dow index was around 7000.  Not sure about natural gas fuel cell there is one electricity generating fuel cell of that sort I have read about in this state.

From now on I will try to resize my article camera photos (I don't own a scanner) as close to the forum's 600kb limit as I can.

BTW, the Hydrogen Highway still isn't going anywhere at the Skylonda facility across from Alice's restaurant. It remains abandoned, parts are starting to rust and the place isn't even secured. The access door leading to a set of stairs was open and the place is really looking sad. What a waste of money. Whoever thought that an H2 refilling station at that location either had their head in the sand, or got a government grant to build it and then just walked away from the project.   

[Specter]

It's all about the money.  Green New Scam.  Govt throws money, they grab it, and run.  Look at Solyndra look at Rivian now, the next soon to be Solyndra IMO.  All they need to do is build it, and the 'owners' whom they built it for, it's on them to make it work, they got their cha ching and are hightailing it out of town.

I have yet to see any H2 vehicles TBH.  I see the trucks carrying it in bulk to deliver here and there but nothing that runs on it.  Funny as it sounds, I actually have a BBQ from like 25 years ago, that burns hydrogen as the fuel.  The meat is really moist when you cook on it, because the 'exhaust' of hydrogen burning is literally, water.  As you can imagine this thing can be stupid dangerous, because well, Hydrogen.  if it accumulates anywhere, it will go off with a bang, and it don't take much at all to set it off, hell a mean look can set it off just about    The good thing is, hydrogen will dissipate very quickly in open air, it wants to rise and do so quickly.

The Hydrogen Highway across the street from Alice's Restaurant was removed last week. I guess the hydrogen highway hit a dead end and is heading for greener pastures.

And so it ends. 

[Specter]

not too many vehicles use it, those that do, fleet ,usually have their refill on site / at the depot, etc and have a big tank of hydrogen, and have someone like airgas come out and fill them up as needed.   hydrogen deliveries are very common, power plants go thru tons of it, its used for cooling and of course leaks.
