Limit to be placed on time at charging stations.

Hydrogen isn't looking promising as a light vehicle fuel.

Main issue is that the cheapest way to produce it from natural gas in a process called steam reforming. It's not very green. Making if from electricity (even if that electric is made by solar panels) is far less efficient (and hence more expensive) than just using the electrify directly to charge a battery.

Other issues are that hydrogen is extremely hard to store & transport - It requires either crazy high pressures or cryogenic temperatures. Also its has a tendency to leak, even through solid metal, and can imbrittle some metals.

Hydrogen is a mature industrial gas, so we aren't likely to see big breakthrough's on the above.

Also note that all fuel cell hydrogen cars are hybrids. The fuel cell doesn't have the peak output to do heavy acceleration, so this is accommodated via a boost from a battery pack and electric motor.

Hydrogen is a great fuel for rockets, and possibility long hall aviation in several decades (is going to be several times more expensive than jet A1) , but I can't see any future for it as a light vehicle fuel.

It tends to leak as the atoms are quite small, so can get through small gaps.

Did you read my responses? obviously not or your boss at toyota didnt bother to read them. i already own latest model highlander released here and have said already i was considering another brand or maybe just hang onto this for a few years. who knows what prospects hydrogen has for running vehicles and what price and all you say is guess work. in 1970 no one knew about cellphones and in 1960 no one knew about internet and in 1987 no one had heard of trademe

by the way only one person from household is supposed to be able to post on message board so may pay to be careful

Yeah. I read them. Like to like upgrades aren't unheard of, especially when an option the owner desires is getting discontinued in the next version. Like when holden dropped the rwd and v8 commodore, or with toyota dropping the v8 landcruiser 200.

Re hydrogen it is a mature industrial gas. Cost of production is known. There could be a massive technology breakthrough, but is is not like people havnt been trying without success for decades.

A vision for hydrogen in New Zealand: Green Paper - MBIE

carbon monoxide is reacted with water to produce additional hydrogen. This method is the cheapest, most efficient, and most common. Natural gas reforming using steam accounts for the majority of hydrogen produced in the United States annually.

That requires natural gas as a feed stock. Natural gas is a limited resource in NZ and the Govt has effectively blocked further exploration.
