" Just one question do you regard hydrogen fuel cell trucks as 100% zero emission or are the companies that make these making false claims."
That is a loaded question that falls within the questionable mumbo jumbo i mentioned.
There are conflicting claims and information that just muck up the whole thing like this:
one claim says: "What type of emissions do hydrogen fuel cells create?
Hydrogen can be produced from diverse domestic resources with the potential for near-zero greenhouse gas emissions. Once produced, hydrogen generates electrical power in a fuel cell, emitting only water vapor and warm air."
Another claim says: Do Hydrogen fuel cells produce co2?
Electric cars powered by hydrogen fuel cells don't produce greenhouse-enhancing carbon dioxide.... It burns with oxygen to make water vapor, and only water vapor-no soot, no nitrous oxides, no carbon dioxide with its potential greenhouse warming.
Another claim says: When the grid is decarbonised, hydrogen fuel cells cars will deliver emissions of 17gCo2 per km, while battery electric vehicles will deliver around 6gCO2 per km. Of course, this does not mean that the electrolysers, like EV charging stations, can't be fuelled by renewable energy.
So is that zero? No it is not.
Besides, i don't count HFC as a viable product in the lift truck industry, they tried it and it was so expensive to purchase and maintain and keep technitians trained and certified nobody wants it.
