Quantum Fuel Systems Technologies Worldwide - also known as just Quantum Technologies - has just announced that it has supplied an as-yet-unnamed fuel cell bus manufacturer with its next generation hydrogen storage technology.

I'm guessing that might well be Mercedes or GM?

GM owns a 19.9% stake in Quantum and so this company is really a bet on near-future hydrogen transport. Quantum is a very scientific company that sees itself as a core component supplier in the hydrogen transport arena, specialising in the design and manufacture of the accompanying systems that run in tandem with a fuel cell vehicle to Original End Manufacturers.

I've travelled quite a few times on a Fuel Cell Bus in London - they are smaller, much quieter and the bus drivers love them. Mechanically, they are more reliable using fewer moving parts. The tough question though is one of cost £900,000 a pop, compared to £200,000 for a bendy bus which carries twice as many people - and range - a mere 100 miles.
