Toyota Mirai

Just read about it on the RACV magazine and done a quick online search.

I had a look at some of the videos.  It seems like a better options then a plug in EV.  Not sure how long it will take for hydrogen infrastructure to be built in Australia.

we already have a huge electrical network to every part of the country all we need to add to it it for plugs ins is the endpoint.

hydrogen infrastructure is start from scratch shipping storage pumping... dealing with leaks.. and the problem is how do we create hydrogen. on scales it's still created from petro-chemicals en.wikipedia.org/wiki/Hydrogen_production electrolysis would seem to require more electricity than required to move a plug in.

I can see hydrogen for long distance transport but not for everyday commuting.

EV - Produce electricity - Charge Car - Drive
H2 -Produce electricity -Produce hydrogen - Transport and store hydrogen - Fill car - Drive

Which one looks simpler and cheaper?

Not to mention the energy density of hydrogen is really, really low. So you need a lot of it to create enough energy to power a motor vehicle for any reasonable distance, which in turn means it needs to be stored at really high pressure to fit in a tank small enough for a car. While these things can be solved, the solutions are expensive and complicated. Finally, it is a really inefficient way of powering a motor vehicle. You only get back about 30% of the energy used to create it, and that's not including the embedded losses from transporting and distributing it. Why use electricity to make hydrogen to then transport it (probably with fossil fuels) and convert it back into electricity in a fuel cell to power a car?

Hey - I got a great idea, cut out the middle man, and just use electricity! Straight electric cars are so much simpler and more efficient at just about every level.
