But, does that really apply here? Electrolysis isn't a heat process but a chemical process?
Im no NE either. Just enuff knowledge to be dangerous! LOL!
Fuel is converted to heat energy thru ignition. That energy is converted to work when it pushes the piston. Only Approx 30% of that heat actually converts to work due to heat loss. (exhaust and cooling system) Of that 30%, some portion is used to run the electrical systems (alternator, that recharges the battery), that supplies the work (movement of the fuel from the storage tank) and ignition source, (the coil, the "sparkers"), for the fuel to be converted to heat and thus the resulting work. I understand about efficiency and loss, but yet our internal combustion engine supplies enuff power to move the car and run its own electrical system.
From that stand point. How much of the wattage generated does the electrolysis event utilize compared to, say, the fuel pump? The Hydrogen engine will require some of the same electrical systems as the gas engine, but with some big exceptions. No fuel "pump". Much less ignition voltage. None of the sensors that use electricity to operate. And the fuel has a much higher yield than gasoline. (Volumetric effeciency?)
Would it be correct to say that the net internal combustion system efficiency loss shows up as our needing to replace the battery every so often. Otherwise, our vehicle system would run indefinitely (save for mechanical failures) as long as the fuel pump could pump fuel from somewhere?
