Honda is better off without them.
Personally think Nissan is better positioned for the EV future and Honda is likely to be the one that needed this more. 🤷♂️
I got excited because I saw a Honda EV, a prologue. Looked it up, it’s a rebranded Chevy Blazer. Honda is absolutely fucked…
Nissan could have been better positioned for EV but they didn’t bother actually doing anything with the Leaf for a decade.
Kinda like how they could have been a high performance brand with the GTR if they bothered to actually do any more development on it for the past decade.
The leaf was an objectively terrible Eevee that probably set the industry back a few years.
Autocorrect changed it to Eevee and I think it works.
Disagree, they are exactly the type of EV we should be building: inexpensive, enough range for around town, pretty dependable. The first couple model years had crappy range, but the later ones were fine.
What Nissan needed was to expand the EV product line. Ideas:
Don’t compete on range at all, that’s R&D you don’t want to deal with. Just make great cars for urban and suburban use.
They weren’t dependable is the problem. There were a lot of problems with early deterioration of the battery, supposedly from not having very good temperature control on the battery pack.
Sure, and battery deterioration is largely only a problem if you don’t have much range to begin with. They put larger batteries in after a year or two, which largely solved the problem for the intended use case: around town car.
But that’s also why I mentioned reliability and price should be the focus. They’re not going to be leading R&D on better battery range, so they might as well focus on a niche.
Range anxiety is not an illegitimate concern though. Sure I probably don’t need that capacity more than maybe once every year but what about when I do need it?
How am I supposed to be able to drive halfway across the country to see my family every Christmas if my car only has 150 miles of range and it takes 4 hours to fully recharge. That’s going to turn a 3-hour road trip into 10 hours if we have to stop and wait for it to recharge. My problem with the leaf was that it had hardly any range at all so that problem was massively exacerbated.
It’s great in a multi-car household where the other car is something with a bit more range but as you’re only vehicle you better hope that no family emergency crop up.
To be clear I would have the same issues with an ICE only had 150 miles of range but in some ways that would be better because it “recharges” faster.
Hence why I focused on vehicle classes more common as a second car. We have two cars, and one never goes further than 100 miles in a given day.
That’s the niche EVs should focus on, especially while battery tech makes >400 mile range impractical. I think Nissan (or any car company) could do quite well focusing on the second car market.
Except the chevy volt is cheaper and has a longer range. Nissan has also done nothing with battery tech or chemistry. That’s all been being advanced by Samsung, toyota and panasonic. There’s nothing the leaf has to offer on a technology front, and there’s no reason to buy one today. Even a decade ago it was a poor choice for 95% of the US market.
Right, which is why I said they should’ve focused on price and reliability. They’re not going to lead on battery tech, so they should experiment with things like sodium ion batteries, which are much cheaper, have less fire risk, and they don’t need the range anyway for a commuter/around town car.
Find a niche and fill it.
Sodium ion is a dead end for ev. Heavy and not even remotely close to energy dense enough. It never will be.
I thought it was something like 75% as energy dense? If you’re targeting a commuter with a max needed range of 150 miles, it seems more than sufficient.
It’s not going to solve the range anxiety problem, but it’s inexpensive, which is perfect for a cheap, around-town second car, which is precisely what the Leaf should be.
Didn’t the Bolt come out 6 years after the Leaf? It should be a lot better in that case as the pace of development has been pretty rapid in EV space relative to normal ICE development
Nah.
Honda has a much better product in the first place, their engineering approach has always been better than Nissan (I say this having worked on every major brand, and some unknowns).
Nissan is one of the better ones, but they’re still a big step away from Honda.
And Honda was working on hydrogen nearly 30 years ago now, which seems poised to suplant batteries (again, maybe).
Hydrogen cannot supplant batteries in mass market cars. It doesn’t make sense, primarily for reasons concerning the laws of physics.
It takes a tremendous amount more energy to power a hydrogen car.
Use a lot of electricity to split water into Hydrogen and Oxygen, force the oxygen to react with another substance leaving pure hydrogen, siphon it away, spend more energy compressing it to bomb-like pressures (or alternatively cooling it until it becomes a liquid, at great energy cost), transport it to hydrogen stations, pump it into cars, do reverse hydrolysis (also incurring a large energy loss) to turn it back into electricity to charge a battery to power an electric motor. [Bonus: since the battery is tiny, it can’t supply a huge amount of power instantaneously - making hydrogen cars far slower than a typical EV.]
OR:
Take that electricity, send it over some wires with over 95% energy efficiency, charge a battery that powers an electric motor.
Then there’s the safety considerations for the cars because they have highly compressed hydrogen on board, the same is true for hydrogen fueling stations which cost a fortune and have an unbelievable amount of red tape. Meanwhile it’s easy and cheap to add charging points everywhere, because practically everywhere already has electricity.
Their range isn’t even much better, because not only is the energy density really bad compared to petrol or diesel, you’re also compromised on fuel tank size due to it having to be small, spherical, unlikely to be struck in a crash (ie must be put in an inconvenient place re: car packaging) and phenomenally structurally strong, all to prevent it from exploding like compressed hydrogen likes to do.
There’s a reason why despite every manufacturer toying with hydrogen vehicles for decades, there’s basically only the Mirai that you can actually buy, for an awful price, and it’s a shit car, while there are several hundred EVs out there right now. One is a viable car technology, and one is basically an EV with a long list of compromises.

Hyundai has one only available in CA.
LOL, no. Hydrogen has never been anything but a greenwashing scam. Even if it were all produced from electrolysis (and to be clear, it isn’t – the vast majority is produced from fossil fuels), it would still be stupidly cumbersome to deal with compared to adding some carbon to it to make synthetic gasoline.
Lol, hydrogen. A chronological oddity. Has spent the last 30+ years just 10 years away from being viable.
Unless they have a fusion reactor they’re not telling us about, so that they can electrolyze water hydrogen is never going to be a viable power source. Currently all hydrogen is acquired through fracking, which makes the entire exercise somewhat pointless.
I think hydrogen has a future, but more for long haul trucking than personal cars. The general idea is to generate a ton of solar power during the day and use the excess to produce hydrogen, and then use the hydrogen to fuel heavy equipment, trucks, and cover for low solar production days.
This solves many of the issues with hydrogen:
Hydrogen remains a solution desperately in search of a problem.
If your aim is to generate locally, why not just use batteries? They’re cheaper, more efficient, and more reliable. Why have the lossy and very high maintenance electrolysis and hydrogen storage/transfer process involved?
Are they cheaper? Even over 1M miles or whatever a truck engine is expected to go? And for running a warehouse overnight? I find that hard to believe.
But even if true, you need to take range into account. Hydrogen cars get better range than comparable BEVs, and that would surely add up for a truck hauling a massive load. And as hydrogen scales up, it’ll get cheaper. It’s currently a bit more expensive than gas (about 3-4x), but that’s with hydrogen transported from some plant somewhere. If it’s locally generated from solar, it’ll probably be quite a bit cheaper.
Yes, significantly so. Hydrogen fuel cells have a much shorter lifespan and higher manufacturing/replacement cost than lithium ion batteries. The compressed gas tanks are also very expensive and have a limited lifespan (albeit a relatively long one, compared to the fuel cells).
Market rate hydrogen is currently about as cheap as it’s possible to get, because it is almost exclusively from fossil fuel sources which are gradually winding down.
Locally produced electrolysis hydrogen suffers from very low efficiency rates; about 2/3rds of the power used to produce the hydrogen is lost in the process. Assuming you don’t have an enormous overabundance of power being generated, it’s more efficient to store the power locally in batteries (which don’t have to be lithium ion if it’s for static storage; other chemistries become competitive if they don’t need to move around) than it is to store it as hydrogen. And if you’re generating a huge overabundance of power such that throwing 2/3rds of it away seems sensible, in most cases the question would be why you don’t make a grid connection and feed in anyway (extreme remote locations notwithstanding).
Hydrogen fuel cells in retail cars are intended to last “the lifetime of the vehicle,” or something like 150-200k miles. Lithium batteries last 10-20 years, which is pretty similar (assuming 10-15k miles/year). They seem to be roughly equivalent in terms of longevity, at least from a quick search.
I don’t know what fuel cells cost to replace, but hydrogen cars cost about the same as an equivalent EV, maybe a little cheaper (Toyota Mirai is ~$50k and apparently drives like a Lexus), so I have to assume the fuel cells aren’t that expensive relative to lithium ion batteries. Also, lithium ion batteries lose range over time, whereas I’d assume fuel cells don’t, but instead lose some generation capacity (i.e. lower top end output).
I thought it was generally about 75% efficient. This article claims the current rate is 39.4kWh for 52.5kWh input. Is that incorrect?
So outside of storage losses (should be minimal if it’s constantly being cycled in and out), 75% seems really good. Current fuel cells seem to be about 40-60% efficient, and I doubt we’ll get significantly higher than that, so is that where you’re getting the “2/3” number from? (40% of 75% = 30%).
The benefits of hydrogen over batteries are:
These don’t really matter for regular cars (can recharge at home over night, etc), but it’s quite useful for an org with high mobile energy needs looking to switch to green energy.
Assuming the same process (i.e. extract from fossile fuels), right? Direct electrolysis comes down to the cost of the energy you use to generate it, and if that’s essentially “free” (i.e. solar power that would otherwise be wasted), that starts to be really compelling.
Battery-powered vehicles require an unreasonable amount of water to control a fire. 1 burning Tesla needs 1 fire truck of water, so imagine what a bigger vehicle would need.
I don’t think the size of the vehicle matters, but where it’s placed. A sufficiently large battery (e.g. something powering a warehouse) is unlikely to be right next to a bunch of important stuff, so they’ll just let it burn out. A Tesla, however, is much more likely to be next to a bunch of other cars, so they need to contain it.
That way though you would have to haul around the electrolyzing equipment with you which seems redundant and it’s pretty heavy. I’m not sure that would necessarily work.
Also in that scenario you would have to keep the water on board so that you could electrolyze it again. That adds even more weight. A molecule of water weighs 18 times more than a single hydrogen atom so every single time you run this process your vehicle suddenly gets massively heavier.
I think you misunderstood me. I’m saying good trucks would use the fuel, not generate it. They’d stop at warehouses and hubs and whatnot to refuel using “waste” energy from the warehouse or hub.
The whole point is that trucks largely take routine routes, so it’s fine if availability is limited because they can plan trips around refueling points. Also, they’re massive, so there are plenty of options for storing the hydrogen since space isn’t really an issue.
Why do you need a fusion reactor for electrolysis?
Because otherwise you’re spending more energy converting water into a hydrogen then you get back from turning hydrogen into water.
You still do with Fusion power but at that point you have so much energy it doesn’t matter how inefficient it is. Seriously even using nuclear power it doesn’t work out as economically viable. It’s really a wasteful and inefficient process.
There have been some recent advances on hydrogen production. I don’t think this (sorry for the MSN link) is the one I heard of, but is an interesting example where cheaper catalysts are improving the efficiency of hydrogen production.
Now, I don’t know if or when hydrogen will be more cost-effective than batteries, which are also experiencing massive advances. This is why I’m going to take the comment someone on Lemmy made about buying used EVs for the next little while - it’s cheaper, they’re lasting longer than predicted, and the advances lined up for the next few years are significant.
