The vast majority of home EV charging happens at night. Is that when CA was telling people not to charge their cars?
Would America even function if gas stations were only open at night?

Hydrogen is less energy per volume than gas, it requires pressure vessels rather than tanks, it's stored pressurized in vehicles and stations, it makes materials it contacts brittle, it relies on a manufacturing process that either requires natural gas production or a huge excess of electrical energy, fuel stations are huge capital costs, etc. I could go on, but it just doesn't make sense to pin hopes on hydrogen.
The exact same thing can be said about EVs and then some. Batteries are less energy per volume than gas. Batteries are extremely hazardous if damaged. They have a relatively short lifespan. They are hardcore industrial hazardous waste. Power generation is likely coming from a gas power plant or even a coal power plant. The required infrastructure upgrades would be astronomical.
A significantly more efficient plant than an ICE.

Huh? Are you not cooking? Our stove needs 1kw and our oven has 6kw. It's not crashing when everyone is cooking why would it crash when everyone is charging? Also it costs more (energy wise) to make H and then consume it than using the energy itself. This should probably has a relevant cost saving. Economy of scale will bring much cheaper batteries very soon. Let's say 10-20 years
Cooking is super bursty, and at variable times, and for short durations. And even then, varies by day. It's not at all the same as everyone on planet earth in the same hemisphere trying to charge their cars during peak summer AC time, between 4 and 6ish pm.
Why do you keep parroting this nonsense? Virtually nobody charges their car at this time
This is one of the many reasons why I firmly believe that hydrogen hybrid are the future to replace gas vehicles. Charging at mass scale is just not feasible nor practical for most people. We can't even roll broadband out properly let alone the massive amounts of infrastructure required to deliver enough power to every home. That leaves centralized charging hubs which will quickly become overwhelmed and a massive tim…
As another top level comment stated, in a lot of circumstances you can make do with charging an EV from a normal outlet. The post was mostly about the challenges with regulations/codes. For the most part it was a plea for governments to smooth over the jankiness they introduce to the whole process. Hardly an insurmountable challenge. Hydrogen is dead. Upgrading the existing electrical network gradually over time (EV…
Converting to hydrogen makes wayyy more sense than EV infrastructure. All of the gas station can be easily converted to hydrogen stations with different pumps and tanks. A lot cheaper than running MW of power for a EV station or upgrading neighborhoods.
Then there are people that live in apartments. It isn't feasible to have a charger for every apartment at a complex. So not everyone is going to be able to charge. Even if it is a normal outlet.
There is also the fire danger. I can't even imagine the amount of damage a fire cause by an EV could do to an apartment complex.
Then there is the vandalism issue and mantaince problems involved.
Only if you are rich dose EVs make sense. But on a mass scale they make close to zero sense.

Why is hydrogen dead? There are a few hydrogen hybrids coming to market like the BMW i3. It has a 300 mile range and can refill in 5 minutes.

Care to cite any sources?
"I'd have to bring my electrical systems up to code and that's expensive for my 80 year old house" Well, yeah. I suppose it would be. I'm a bit surprised this is a surprise to the landlord. Also, many of the costs here are looming anyways. It's a matter of when, not if, the electrical needs updating to meet code.
That's not necessarily true. It sounds like most of the upgrades are about convenience to the power company. Not anything safety related, which is why older properties are exempt. You also have to remember that it takes a lot of power to be able to change an EV in timely manner. It is easily the number one consumer of energy. Older neighborhoods utilities where never designed to do that.

> It sounds like most of the upgrades are about convenience to the power company. Not anything safety related, which is why older properties are exempt. That is definitely not true. An 80 year old house might not even have grounded outlets, let alone GFCI or AFCI protected outlets. > You also have to remember that it takes a lot of power to be able to change an EV in timely manner Nobody worries about how many electr…
240v at 30A is most definitely not a trivial load. Most homes have 100 amp service. That would be 30% of your homes total power capacity just for changing EV. You wouldn't be able to run AC and the dryer and charge an EV at the same time at that rate. But more importantly there is only so much power at the pole.

Charging at scale is just way easier & cheaper than deploying hydrogen infrastructure, and I don’t think people realize just how big of a difference there is. It takes approximately 4 times the electricity (when you include liquefaction, inefficiency of electrolysis, etc) to drive the same distance with hydrogen cars as with electric cars. And Hydrogen cars get about the same range on a tank as electric cars, but eve…

no, the property will just burn down in a fiery electrical explosion killing anyone unlucky enough to have been there after the contractor missed the ancient arts necessary to avoid that. municipalities lack consensus for any other outcome to occur, they are all land fiefdoms.
I'm on board with what you're saying, but also electrics done to "code" can burn down your house. My mother in law told me yesterday that my sister in law's mother in law's house burned down while they slept (they're safe) this week due to brand new electrics in a brand new house extension, carried out by a licensed (is that the correct word for an electrician?) professional. This is in England
