Crestline Bike Co. Announces 2 New eMTBs
@hamncheez: That does sound expensive. Many current vehicles using hydrogen use a 700bar rated carbon Fibre tank. It sounds like you and/or your university are researching hydrogen storage for use in hydrogen fuel cells. When speaking of a hydrogen fuel cell, I am strictly referencing the "chamber" in which oxidation takes place and electricity is produced. Certainly experimental versions of fuel cells are pricy by nature, and in the case of what are you are describing, solid-state storage of hydrogen in a hydrogen permeable solid medium would I suspect be expensive. I know nothing about it except that it exists and the hope is to more safely store larger a larger mass of hydrogen at lower pressure. Sounds like something aimed at aerospace as hydrogen storage is one of the bigger barriers challenging the use of H2 in aircraft. Anyways, I'm not trying to be a dick, and I'm confident whatever is being done at your University is cutting edge and justifies the cost, but I'm also confident there are cheaper modalities being used by industry for many years.

@hamncheez: I don't know what you mean by $200 000/kg for fuel cells. I don't doubt their lab setup may have cost that, or simply the cost of the fuel cell required for their use case. But just like batteries and combustion engines size and use cases affect prices. Check out the Toyota hydrogen car. That runs off a fuel cell. You can also buy very basic water electrolysis hydrogen expirment kits on Amazon for under $5000 for educational use. If your talking a per kg price I would expect that to be referencing the cost of the fuel itself. Hydrogen is a similar price to many fuels with regards to available energy vs cost. Quoted per m³, our labs have purchased it at $1.50/m³ not including delivery cost, tank rental, etc. All that to say it is scaleable, and while not cheap, certainly more affordable than suggested, though I doubt there could be a use case on a mountain bike... maybe some sort of electric cargo bike where weight and space are less of a concern.

@hamncheez: lol, that is not correct... fuel itself is 10-15$ a kilo. Fuel cell cars start around $50 000.

Video: Controversial Features? - Inside the Tape at Vallnord
Ski matting is always a terrible idea!!! I've seen a few really bad crashes caused by it during practice at Windham WC years back due to the matting lifting as riders cornered or braked! F that stuff!!!
