Toyota wants hydrogen to succeed so bad it’s paying people to buy the Mirai::Toyota is offering some amazing deals for its hydrogen fuel cell-powered Mirai. That is, if customers can find the hydrogen to power it.

And most electricity is still made from fossil fuels. The point is that it doesn’t have to be, unlike gasoline.
Depends where you live. Plenty of countries with high % of renewables
Yup, I think there is a solid argument BEVs will win in the long run (once battery technology improves … all the downsides of BEVs start disappearing rapidly). However, I haven’t ever liked the argument that “most hydrogen is made from fossil fuels” that’s looking too short term.
There’s loads of studies surrounding that. It isn’t expected to change. This because they’re planning to create hydrogen from gas in such amounts that it’ll not cause too much of a change in the percentage of green hydrogen (which is currently as good as non existant).
Hydrogen is also expensive, so it’s pretty difficult to get a factory (e.g. steel factory) to switch to hydrogen.
We will run out of fossil fuels someday. We can also just ban making hydrogen from fossil fuels and then selling it to car manufacturers. Just like with battery demand … you get the demand increased and research will take off from there to find ways to make it cheaper and faster.
Currently literally 99% of the world supply of hydrogen is fossil fuels. Yes, in the “future centuries” sense of the king term things might be different, but in the “we need to stop climate change in the next decade or so” sense it’s a non-starter. If you banned companies from making hydrogen from fossil fuels, the world simply wouldn’t have enough hydrogen.
It’s basically not possible to make electrolysis more efficient; the energy requirements are simple physics. The only way that technology can make green hydrogen cheaper is to reduce the capital cost of building an electrolysis plant, and to make enough surplus electricity that the cost to ring it comes down. Although as the latter also makes recharging a BEV cheaper too, that doesn’t necessarily get hydrogen anywhere closer to being competitive.
My thought is we could feed electrolysis with nuclear, solar, or tidal generation plants to create hydrogen. That doesn’t mean it would be cheap, but maybe it could get us to the quick refill infrastructure we have with gasoline currently that we’re having trouble mirroring with BEVs for long trips.
I haven’t run the math … so if you have or you know a source that has and this is beyond uneconomically feasible (like it would cost $$$$$ for a single “tank of
gashydrogen”), fair enough.For comparison, grey hydrogen currently costs around $2 per kg, and green hydrogen costs around $12 per kg. Filling a Toyota Mirai tank with green hydrogen would cost you about $70. That’s production at today’s electricity prices. The cost to fully charge a Tesla is about $15, same rates.
So for green hydrogen to beat grey hydrogen on the open market, costs need to drop by a factor of 6. And because it can only do this if electricity prices drop off a cliff, it’d be doing this in an environment where you can fully charge a luxury BEV for $3…
Hydrogen is also not the only game in town in terms of competitors with BEV. For those niches where fully battery-operated vehicles aren’t practical, there are also biofuels, which are (from a climate change point of view) greener than green hydrogen anyway (although they have their own controversies).
I don’t think battery tech needs to improve, it will, but I don’t think it needs too.
Prices are going to drop. Will be interesting to see what happens is BYD sets up in Mexico. But lithium for high end cars and sodium for cheap cars I think is enough to push the revolution.
I’ve written about my delima with buying a BEV (beyond the price) a bit already … here’s a link to that https://social.packetloss.gg/comment/1334210
Basically, I do think either the battery technology or the charging infrastructure themselves need a fair bit of improvement before we’ll see the average person adopting them enthusiastically.
As time goes on there will be more chargers and less petrol stations.
What I’m saying is if the price keeps coming down battery tech is good enough today.
Like hypothetically if electric cars were half the price of normal cars and there was 10x as many charging stations you wouldn’t need better battery technology.
But battery tech will get better and cheaper and there will be more charging stations. I get their are issues now.
That’s not true, Gasoline doesn’t have to be made from Fossile fuels either. It’s pretty easy to make actually - there are a number of European companies doing it and with the Co2 Taxes, it will be a viable option by 2028.
Gasoline is made from petroleum.
It is certainly synthesisable by some method without using petroleum. But the person you replied to probably meant Power-to-Gas.
However synthetic or not, burning it produces same gases, which are the problem. Cleaner, but not the end solution.
Biogasoline is a thing, although I’m not aware of anyone really pushing it as viable fuel above biodiesel, ethanol, and bioLPG.
Yeah but you can charge EVs with solar panels if you have them installed. Not everybody can make hydrogen for their Toyota Mirais.
