UK Company Riversimple Plans a Fuel-Sipping Hydrogen Car (techienews.co.uk)

Posted by yaelk on from the environmental-cars dept.

TechnoidNash writes: Riversimple has been developing a hydrogen car with the support of a 2 million grant from the Welsh government. The result of their efforts? The Riversimple Rasa. A hydrogen car with a claimed fuel economy of 0.9L/100 km (250 mpg). The Rasa can reach up to 96 km/h (60 mph) and has a range of 483 km (300 miles) on a 1.5 kg tank of hydrogen.

    Having the vehicle not fall to pieces due to hydrogen embrittlement, also an issue.

    That's a very well known issue solved by material selection.
    Messing it up would be equivalent to making an umbrella out of sugar.

    As Musk explains:

            “Hydrogen is an energy storage mechanism. It is not a source of energy. So you have to get that hydrogen from somewhere. if you get that hydrogen from water, so you’re splitting H20, electrolysis is extremely inefficient as an energy process. if you say took a solar panel and use the energy from that to just charge a battery pack directly, compared to try to split water, take the hydrogen, dump the oxygen, compress the hydrogen to an extremely high pressure (or liquefy it) and then put it in a car and run a fuel-cell, it is about half the efficiency, it’s terrible. Why would you do that? It makes no sense.”
