No - I was only joking -
do you really want to have something that is at 10,000 psi and flammable if you crash?

And socko just can't wait to open up a hydrogen fool bowser and make 1 cent per liter profit and hoping the punters will make up the difference by buying more chocolate bars from his store LOL

dear Juliar,
All I'm saying is that anything -
& especially something flammable at 10,000 psi is incredibly dangerous.
Petrol is bad enough but it least it's not pressurised.
There is no doubt that Lithium batteries are also dangerous.


Also - what about trying to fill up a tank of hydrogen at 10,000 psi?
You are dealing with cryogenic temperatures that could instantly
freeze your fingers.
What is stopping the nozzle from coming loose & forcing out
hydrogen at 10,000 psi into your face?


Juliar - no offence as your heart is in the right place - but I don't
believe that you or anyone else here including me
are qualified to assess all the dangers & quantify them.

Hi Nail,
and Juliar has failed to come back to this thread and apologise
for posting nonsense when confronted with the facts.

dear Juliar,
I wonder which hydrogen storage method will prevail?
All will have their positive and negative attributes.

I still think battery cars will win this race.
At least you can charge them from solar panels so
it costs nothing except the setup cost.
People will not be reliant on petrol or hydrogen filling stations.
They won't be slaves to multi-national companies charging them for fuel.

The shrunken heads of the lying SPAMMING TROLLS are drowning in their own uneducated GROSSLY IGNORANT TECHNICALLY OBTUSE SLIME.

Oh Bobby you and Lee are the ONLY intelligent beings here.

I am just slagging the disreputable useless troll with the IQ of a deceased ant. And there are two of these Greeny type trolls making the place untidy.

The exciting future of the hydrogen energy revolution gets ever more exciting while the dead end all electrics languish in the doldrums of range anxiety inconvenience.



New catalyst material could ignite fuel cell revolution
23rd January 2018 11:08 am

A new type of catalyst to replace the platinum in fuel cells could potentially make hydrogen-powered vehicles considerably cheaper.



Developed at the University of California, Riverside (UCR), the material is made of porous carbon nanofibres embedded with ions from either cobalt, iron or nickel. Due to their relative abundance, these metals can be up to 100 times cheaper than platinum, a key component in most polymer electrolyte membrane fuel cells (PEMFC) used today. The work is published in the journal Small.

Employing a technique called electrospinning, the UCR researchers made paper-thin sheets of carbon nanofibres embedded with the metal ions. Once heated, the ions formed ultrafine metal nanoparticles that catalysed the transformation of carbon into a high-performance graphite. The metal nanoparticles and residual non-graphite carbon were then oxidised, leading to a highly porous network of nanoparticles dispersed in a porous network of graphite.



“The key to the high performance of the materials we created is the combination of the chemistry and fibre processing conditions,” said David Kisailus, Professor in Energy Innovation at UCR’s College of Engineering. “The remarkable electrochemical properties were primarily attributed to the synergistic effects obtained from the engineering of the metal oxide with exposed active sites and the 3D hierarchical porous graphitic structure.”

In collaboration with researchers from Stanford University, the UCR team demonstrated that the catalytic nanocomposite performed as well as platinum-carbon systems, but at a fraction of the cost. According to Kisailus, an added benefit of the was that new material’s graphite fibre provided additional strength and durability, which could enable it to serve as a structural component as well as a fuel cell catalyst.

“An important challenge in making high-performance vehicles is reducing weight, both from the body of the vehicle as well as extra weight from the battery or fuel cell, without affecting safety or performance,” he said. “The material we created may enable automakers to turn structural components, such as the hood or the chassis, into functional elements that help power cars.”

Once this is combined with hydrogen stripping from liquid fuels, and the carbon used in the new 600 degree carbon fuel cell, I see EV’s being truly electrical without the obvious drawbacks of battery powered vehicles.

Net result is water vapor, and carbon dioxide with the CO2 in its own pure stream, heck, maybe even capture that as liquid CO2, and discharge it to storage when you fill up.

The CO2 has its own uses, including green house growth accelerator, so atmospheric release is not necessary. This can be a real boon, renewal fuel or not.

I always thought fuel cells were the answer. Much better than batteries.

Put this together with the report on photon friendly graphene membranes and we are getting somewhere.
