It's the most abundant element in the universe in a pure state, however on planet Earth it doesn't exist in a pure state as it is almost always bonded to other elements and compounds - short version: it doesn't exist in an extraction-friendly state. It is incredibly challenging, dangerous and expensive to extract or produce sucessfully. Storing for a reasonable amount of time it is another challenge. The "juice must be worth the squeeze," so to speak

Needs a very good air filter!

First Mode developed the fuel cell.. AA installed it

For others who want to waste money.

Yes

One can assume the alternator isn’t used

The truck is only zero emissions in terms of energy use to power it. The amount of emissions to produce the truck and associated infrastructure is huge.

No it's , it will save million of Rand's and CO2 in a matter of years

Funny you mention conversion efficiency. A company called Hysata has developed a capillary based electrolyzer which can produce a Kg of hydrogen at a cost of 41.5 Kwh. Since one Kg of hydrogen holds 39.4 Kwh of energy this represents a 95% conversion efficiency. The power to mass ratio of hydrogen is 41.5 Kwh / Kg. Lithium batteries have a power to mass ratio of only 11.6 Kwh/Kg new, which continues to degrade over the life of the battery. And speaking of battery life, it is a very dirty process to produce lithium batteries and a very dirty process to dispose of them. As well, hydrogen is a much better storage mechanism for electricity produced from the discontinuous methods of solar and wind. While sustained high winds produce too much power for the grid, hydrogen technology easily captures every Kw. Hysata believes it can drive down the price to $ 1.50 per Kg of hydrogen. With FCEVs getting around 80 miles / Kg this works out to around 50 miles / 1 $. In California 1 Kwh is $ 0.25. With BEVs getting around 4 miles per Kwh this works out to around 16 miles / 1$.

@@robertcarpenter8077 the real metric of concern is not kWh/kg but rather kWh/m3. In any event...even with a high efficiency in creating hydrogen...turning it back into electrical energy is around only 30% efficient this I know from various fuel cell providers....even worse than diesel. Oh...and by the way the PGMs used in the catalysts were definitely not created from a green process either. Finally claims of such high conversion efficiency have not been independently verified and they are always two years away. Hydrogen would probably make more sense in a combustion engine than in this type of application.

Stop talking crap!!!! Hydrogen powertrain can work almost 24/7 like diesel unlike batteries that needs along time to charge and also batteries only works on sites with up/downhill, hydrogen works everywhere just like diesel. Hydrogen has a lot more applications in the industry and is already replacing coal in steel production……

@@robgood9119 it doesn’t matter it’s still a Bette solution that batteries or diesel

@@alanmay7929 wow.. You are lost..please go and study the details. Hydrogen will always be bonded to something.. that's why we came up with a name for it.. hydrogen bonds. Because it always is attached to something you will always need to put energy into it to break the bond. I.e hydrogen may be abundant, but not in the form you want it. Once this is done you need to put more energy in to have the catalyst react and transfer electrons and again have a new bond formed with oxygen.. i.e water. All this costs a great deal of energy. Much easier and efficient to charge a battery. Anyway.. I am sure this will not penetrate your skull
