In case you are worried Hydrogen cars will take over EV....next time u have mates over at your BBQ you can tell em this:
Hyrogen:
Let’s take 100 watts of electricity produced by a renewable source such as a wind turbine. To power an FCEV, that energy has to be converted into hydrogen, possibly by passing it through water (the electrolysis process). This is around 75% energy-efficient, so around one-quarter of the electricity is automatically lost.The hydrogen produced has to be compressed, chilled and transported to the hydrogen station, a process that is around 90% efficient. Once inside the vehicle, the hydrogen needs converted into electricity, which is 60% efficient. Finally the electricity used in the motor to move the vehicle is is around 95% efficient. Put together, only 38% of the original electricity – 38 watts out of 100 – are used.
Fully Electric:
With electric vehicles, the energy runs on wires all the way from the source to the car. The same 100 watts of power from the same turbine loses about 5% of efficiency in this journey through the grid (in the case of hydrogen, I’m assuming the conversion takes place onsite at the wind farm).Energy efficiency in electric vehicles.You lose a further 10% of energy from charging and discharging the lithium-ion battery, plus another 5% from using the electricity to make the vehicle move. So you are down to 80 watts – as shown in the figure opposite.In other words, the hydrogen fuel cell requires double the amount of energy. To quote BMW: “The overall efficiency in the power-to-vehicle-drive energy chain is therefore only half the level of [an electric vehicle].”
AND ....who is going to put up all the hydrogen fuel stations?...
