I’ve posted here about Hydrogen vehicles, gas/eletric hybrids and straight electric.
How about a gas/hydrogen hybrid?
Powering a vehicle by Hydrogen is by no means a new idea, and in fact, almost all automobile manufacturers are currently developing a new generation of vehicles that run on Hydrogen as opposed to Gasoline. This new generation of vehicles are essentially electric cars that use a Fuel Cell instead of a battery to run the electric motor. Using a chemical process, Fuel Cells in these new vehicles convert the stored Hydrogen on board, and the Oxygen in the air, directly into electricity to power their electric motors. These new Hydrogen powered electric vehicles are very efficient, and in fact are more efficient than any internal combustion engine. The problem is that these new vehicles are years away from production, are very expensive, and converting to using Hydrogen fuel in this manner requires you to buy a new ( and expensive ) vehicle. All Hydrogen/Fuel Cell systems currently under development by large manufacturers have you purchase Hydrogen as you would Gasoline.
Their kit will even come with a solar or wind powered Hydrogen Generator, so fuel cost will essentaill be zero.
They bond hygrogen to other chemicals for transport, so you won’t be rolling a giant potential $1M fireball. All that’s needed is a little heat to release the hydrogen and you are good to go.
Due to the fact that Hydrogen gas burns so much faster than Gasoline, engines with compression ratios greater than 9.5 to 1 are very susceptible to damaging predetonation (engine knock). For this reason, Hydrogen conversions are not recommended for vehicles with turbochargers, superchargers, or compression ratios greater than 9.5 to 1. Also, because of the higher compression, different ignition system, and host of other factors, the Hydrogen Fuel System will not work on diesel engines.
It will probably cost a bazillion dollars, but it’s neat to know that this is turning into a reality much faster than I originally thought.
