Gotta be great for the economy. Gotta be great for his ‘obligated’ reelection. Gotta be great for the average American. Because America is:
Racist, xenophobic & capitalistic.
Sorry Biden voters. You won’t change anything.

Nothing but the rate at which the cancer spreads.
We don't have time for this shit 😒
BYD made the most rich white suburban mom car in the world (Yangwang U8, look it up) and immediately got kicked out of the market lmao
zero chance they move those without the US market 🤣
I don't know if it's a lie but BYD currently state they have no active plans for sales in America of their vehicles.

This really do sound like they mock Tesla.
I'd like that if it was the size of the new bronco
Jfc....you weren't kidding
If Biden really wanted to stick it to the Chinese auto industry, he'd fund a national build out of hydrogen refueling infrastructure and substantial subsidies for fuel cell production.
Hydrogen doesn’t make sense and never did as a strategy to reduce greenhouse gas emissions in vehicles.
Most hydrogen is made from fossil fuels, and has a lot of emissions during manufacturing. But even green hydrogen, which is made by using carbon free generated electricity to split water into hydrogen and oxygen doesn’t make sense.
If you’ve build new renewable power it’s more efficient to use it to charge batteries than to use it to generate hydrogen.
There might be a case for compressed hydrogen, In vehicles where batteries are too heavy like aircraft.
But for road vehicles, batteries are more effective at reducing emission.
If you’re building any new renewable power, you’ll reduce more emissions by using it to displace coal power, the to generate green hydrogen.
Some day when we’ve eliminated fossil fuel based electricity generation, Green hydrogen might start to make sense. But anybody trying to do it right now is not being as helpful as they could be.
You're not really describing a problem with hydrogen powered vehicles. You're describing the problem with the way we've been trying to generate power free of greenhouse gas emissions. As long as the policy makers keep myopically insisting that we only do it with certain renewables, it doesn't matter if battery electric vehicles are actually more efficient or not. So, on balance, the relative inefficiency of a hydrogen powered fleet is more than made up for by avoiding a massive stream of battery waste that everyone seems to be ignoring.
Yes you’re correct. I will qualify my previous statement as hydrogen powered road vehicles don’t make sense for now.
The problem at the moment is that electricity generation is not carbon free and in most countries not even close.
Unfortunately the transition to a carbon free electric grid is being significantly retarded by policymakers that are, as you say, myopic. As a result it will be at least two more decades before hydrogen makes sense.
The carbon footprint of lithium battery manufacturing, is small compared to the carbon footprint of electricity generation. Until that changes significantly lithium batteries will continue to be a better choice than hydrogen fuel cell.
Hydrogen may make sense in a future where we’ve eliminated all fossil fuel electricity generation and there’s an abundance of carbon free electricity that can be used to create green hydrogen as a form of energy storage. Though by the time that point comes, we may have developed battery technology or some other energy storage technology that doesn’t carry the same carbon footprint that lithium ion does today.
I'm not so concerned about the carbon footprint of battery manufacturing as I am with the broader externalities associated with the battery lifecycle. This article is a few years old, but it provides a relevant, sobering assessment of the problem. Hydrogen powered vehicles make sense now because they avoid that problem. They're also a better choice for anyone whose driving needs would outpace overnight charging of a BEV at home (or anyone with a living situation that precludes it). The current policy of exclusively transitioning the fleet to BEVs is at best a kludge for bad energy policy.
Hydrogen weakens the metals that it touches and it explodes. Now you want to have tax dollars install time bombs across the country? Let's skip hydrogen for safety reasons and use electric. The grid is there and getting charging stations is infinitely easier to install than hydrogen infrastructure.
Hydrogen embrittlement is a solved problem. You just design for it. And the grid is not there to support a transition of ICE vehicle fleet to battery electric. A significant build out of infrastructure is required especially for recharging battery powered long haul trucks within reasonable times.
Is fuel cell tech actually easier, cheaper, or better than batteries in any way?
Nope! And most hydrogen is fossil fuel (methane) derived and horribly energy inefficient. At this point it's green washing at best.
Edit: adding data:
Steam-Methane Reforming (SMR) accounts for about 95% of all hydrogen production on earth. It uses a huge amount of heat, water, and methane to produce hydrogen.
https://en.m.wikipedia.org/wiki/File:SMR%2BWGS-1.png
For inputs:
- 6.2MWh of Heat
- 2.2 tons of Methane
- 4.9 tons of pure water
The outputs are:
- 6 tons of CO2
- 1.1 tons of H2
The overall energy in vs energy out is at most 85% efficient. https://www.sciencedirect.com/science/article/abs/pii/S0016236122001867
Hydrolysis, the main competing method, and the one most touted by hydrogen backers, accounts for about 4% of hydrogen production.
This method takes in only pure water and electricity, but it's efficiency is abysmal at some 52%. In every case, a modern kinetic, thermal, or chemical battery will exceed this efficiency.
Other methods are being looked into, but it's thermodynamically impossible for the resulting H2 to produce more energy than it takes to create the H2. So at best today we could use H2 as a crappy battery, one that takes a lot of methane to create.
It's called electrolysis, and is now at 95% efficiency: https://newatlas.com/energy/hysata-hydrogen-mass-production/
When it's a documented scientific process and it's scaled up and used in the real world to displace the other methods, I'll be ready to acknowledge hydrogen as a valid part of energy infrastructure.
Yes. There are too many Tesla fanboys (still) that have a misinformed understanding of the facts. They don't realize that Tesla is just lying to them. Tesla don't want people to think that there are better cars or better technologies out there.
I'm confused. Why are we talking about Tesla?
The idea that fuel cells are bad or impossible is marketing from Tesla. It's the reason why you see posters talk negatively about fuel cells.
What are the benefits of fuel cells?
Do they outweigh the benefits of batteries?
It is another way of converting chemical energy into electricity. Basically, another way of building an EV. And since you don't need nearly as big of a battery to power an EV, it is a sensible way of reducing cost, weight, etc. while still achieving zero emissions. There are absolutely situations where those upsides significant outweigh the downsides.
If people were honestly in favor of EVs or zero emissions in general, they would definitely look at fuel cells seriously. But unfortunately, they don't, because they are mostly Tesla fanboys who want Tesla (and only Tesla) to succeed. So they demonize it, alongside everything else including PHEVs and hybrids. Which is why you see posts from "EV fans" that hate most types of EVs.
Yeah, I know what a hydrogen fuel cell is.
What I'm saying is that the cost to develop hydrogen infrastructure, the complexity of it's distribution, the risk due to its high volatility, and the uncertainty of a relatively underdeveloped technology all seem to be losing to batteries, which are very mature tech and are already in the supply chain and for which we already have a well developed electricity distribution grid.
I just don't see what investing in fuel cells will do other than slow the adoption of zero emission vehicles by another decade.
We are nowhere near capable of replacing all cars with battery powered cars. Their supporters are just handwaving away the problems. In particular, we have no straightforward way of both converting the grid to 100% renewable energy, while also massively increasingly electrical demand for things like BEVs and every other electrification proposal. In reality, it's just a big fantasy.
The "success" of battery cars right now is really due to huge subsidies and a willingness to overlook fundamental problems (such as mining challenges, child and slave labor, no way for non-homeowners to charge conveniently, etc.). If we actually looked at those problems honestly, we'd realize that they are as big or even bigger than the challenges of building a hydrogen infrastructure.
This gets much more problematic once we look at heavy transportation or industry. We have no method of electrifying airplanes or ocean-going ships and many other things. So all of the expense of electrifying cars is just one part of a much larger decarbonization process. And that larger process absolutely requires a hydrogen infrastructure somewhere. So we pretty much have to build a hydrogen infrastructure anyways. As a result, dismissing hydrogen is just not taking climate change seriously.
Lol. Blaming Tesla for all of hydrogen's woes is just buying your head in the sand.
I've been following hydrogen vehicle development long before Tesla even existed. The field has effectively stagnated since the 90's. Same promises for the past 3 decades with no substantial improvement. The hydrogen car of today is still the same hydrogen car of 1995 with a better infotainment system. Cost, storage, distribution, range are all problems that have yet to be solved and again are still not substantially better than what we had in the 90's. Every "revolutionary" hydrogen technology from the labs have basically gone nowhere.
It seemed like a viable competitor to batteries in the 90s and early 2000s because battery technology and prices weren't up to snuff. But hydrogen has stagnated while batteries have improved. Hydrogen is a "solution" that is 2 decades behind at this point
It's the primary source of this type of rhetoric. And you sound like someone who fell for it hook, line and sinker.
Battery powered cars are well over 100 years old. They only exist in number right now because of huge subsidies and because governments are mandating they happen. They would not be popular at all otherwise. If we subsidized hydrogen cars to the same extent, we'd be talking about the success of hydrogen cars right now.
The problem is that battery cars are not a viable alternative to most types of ICE cars. People have drank so much kool-aid that they forgot this obvious fact. So they engage in this delusion where the BEV industry is somehow already ascendant, when in reality it is barely a viable business. Which is also why Biden is raising tariffs on Chinese EVs (the OP BTW). Only China is subsidizing BEVs to the levels needed to make it work. Something few other countries are willing to do.
You keep saying stupid phrases like "people drinking the kool-aid!!!" while you're doing nothing but pouring out Kool aid yourself.
In case you weren't aware, Hydrogen cars ALSO got massive subsidies. They received these subsidies far before Tesla even existed, before BEVs took off, when hydrogen looked like the more viable alternative.
They had the head start, they got government subsidies, government backed infrastructure, AND manufacturer incentives. They had the public opinion back then too, with celebrities like Top Gear endorsing hydrogen over batteries. They are STILL getting government incentives today.
It's still not enough. The bottom line is that it's still inconvenient, expensive, and highly limited. If they spent the US military budget to force the issue, they could, but why?
Battery vehicles won because they met consumers' needs, not some grand conspiracy against hydrogen, and not because everyone hangs on Musk's every word.
Even 10 years ago, I could buy an EV anywhere in the country and it would meet 99.5% of my driving needs if my home had a garage. Hydrogen cars were STILL limited to a 100 mile radius to the nearest filling station, which is basically the California coast. And you had to pray the filling stations didn't run out of hydrogen. It didn't matter how much the vehicles themselves cost. Whether they were $200,000 or free, with a hydrogen car you could only go 100 miles from the pumping station, and only when the pumping station was full. With batteries, you were always full all the time, and you could always go 100+ miles from home. Even before any fast charging stations were built, if you took a short road trip and stayed in one location for a few days, you could go 250 miles away and slow charge at your destination simply by bringing an extension cord.
Electricity is cheap, too. Hydrogen was, and remains, expensive. EV buyers could look forward to not paying ridiculous gas prices. Hydrogen buyers had to look forward to paying MORE per mile than gasoline.
You keep whining about batteries not being the perfect solution to every single vehicle on the planet. Guess what? Average consumers are not driving every single vehicle on the planet. Average consumers are buying midsize crossovers. They drive to work and around town, and maybe do a road trip once a year. They can charge at home and never worry about whether or not the local filling station will run out of electricity. BEVs have won the suburban consumer segment, period.
As charging stations get built out, they will soon meet urban consumer needs, too.
Hydrogen might have some place in industrial processes or long haul trucking, possibly aviation maybe. But it makes absolutely no sense for regular consumers.
Hydrogen can cause "hydrogen embrittlement," which makes the storage and transportation of hydrogen inconvenient. "Hydrogen embrittlement" refers to a phenomenon where metal materials become brittle and prone to fracture after absorbing hydrogen. This phenomenon poses significant challenges for the storage and transportation of hydrogen.
Yes but hydrogen has storage problems in that it messes with storage containers making long term storage potentially hazardous. How much of that last part is bullshit I am not qualified to answer but it sounds fucky to me.
That is not true. I'm working on a hydrogen refueling project right now with a steel, ASME code storage vessel. I asked the manufacturer specifically and they confirmed that hydrogen embrittlement is not a concern and does not affect the lifetime of the vessel.
