quote: Internal combustion engines are at best 30% efficient while a fuel cell is generally 40-60% efficient.
quote: Also, why do people only think of cars when talking about fuel cells? They are a way to produce energy, it isn't only useful in vehicles. I know that some data centers are using them as a backup power source and even to offset their external energy use.
quote: Where are you getting all those numbers for the efficiency of various stages of hydrogen production? Seems to me like you're just pulling those out of thin air.
quote: Plus, even if they are accurate, you're obviously not taking into account the efficiency of the new process described in the article, since it's not a current manufacturing process.
quote: Plus, what are the numbers for the various stages of extracting/transporting/burning gasoline and ethanol? You claim that both are more efficient than hydrogen, yet don't provide any proof.
quote: Really, if hydrogen can be produced efficiently, then the only issue left is storage, which is an engineering problem that would be solved fairly quickly
quote: the flammability of hydrogen. This moves forward on the production side of the issue. We still need to deal with how to store it safely.
