Milford Haven Hydrogen trial - including Riversimple

[dan_b]

Anyone interested in the results of the Milford Haven Hydrogen trials the reports are now available. Including the efficiency of the Riversimple Rasa of
110mpk (miles per kg) so a range of 165 miles - not 300+ as has been claimed. Quite a lot of information in this 107 page document, but it's quite revealing too.

When you're finished reading a quick appraisal of hydrogen in this super lightweight class of vehicle compared to modern bloated vehicles would be useful if you feel inclined.

It's awful.

So with 1kg of hydrogen = 33.6 kWh the Riversimple Rasa does at best 3.27 miles/kWh and 2.52 miles/kWh at worst.
So this tiny 2 seat FCEV runabout, limited to 60 mph, allegedly designed to be all about efficiency, is worse than a full size production spec 5 seat Kona Electric SUV. It's worse than pretty much all full BEVs already on the market.

The report linked in this thread is a masterpiece obfuscation, selective data and wishful thinking. It seems EVs are expensive to charge because electricity is linked to gas prices but H2 will be cheap because they’ll make it with solar power…
And to make 1kg of H2 they say requires 50kWh of electricity.
And they say that there's a shortage of green electricity which means full BEVs are never going to be "The answer". But their Hydrogen answer is way less efficient and uses the said same "green electricity" which could take you 3x as far for the same energy input...

The snag is that it is now normal to misrepresent and obfuscate in order to attract investment for impractical ideas. It's actively encouraged by all those with a stake in making money from investments. People see nothing wrong with distorting facts, often grossly, if that gives them a chance of attracting funding for their pet ideas. Is this really any different to the way the Drax biomass conversion was sold as being a "good idea"?

Than!s for that Dan, ..put bluntly in ways an mp would understand then, a first gen nissan leaf is more fuel efficient than the "modern miracle" (by sleight of hand & B.S. hyperbole) than the great white hope of hydrogen.

Speaks mounds.

Not sure that "the great white hope of hydrogen." is the right phrase, not even great green hope, or great blue hope, but rather the great FF industry hope, great black hope of hydrogen?

Whilst there will likely be a large demand for hydrogen to replace carbon in many situations (e.g. steel makng), I believe that the main driver for hydrogen is not RE but FF, as they know that the idea of producing all the hydrogen needed from RE will probably take much longer than the optimists expect allowing them to still peddle their wares. Until H2 produced from RE is low cost, the idea of producing it from excess RE will be very hard to imagine, who would build an H2 plant that is only going to run for short periods with a very low load factor when the FF can still produce it for a lower cost.

[Mr Gus]

Too many colours where H2 is concerned, ..all of them faecal brown it seems!
