They don’t have to sell hydrogen or solar panels. They’ll just keep selling fuel to power plants.
That’s a lot of future e-waste to lug around just for cooking.
Their days aren’t numbered until governments actually say so. In the meantime, non-GHG emitting sources supply less than half of the world’s electricity as is, nevermind the hypothetical demand of a predominantly electrified vehicle fleet.
Unfired pressure vessels are already pretty common common in industrial, commercial, healthcare, transport, and recreational settings. I am comfortable with continuing to trust the engineers as the portion of these vessels that contain hydrogen increases.
Fossil fuels, including coal, are also used to produce electricity. They simply need to be prohibited or at least strictly rationed. Fortunately, hydrogen can be produced without emitting greenhouse gasses because it is still necessary for processes like steel and fertilizer production. It’s also a practical replacement for fossil fuels in transportation and, as Toyota demonstrated, food preparation. As I replied to someone else, sometimes we need portability and/or a flame when it comes to cooking. Electricity just doesn’t cut it in those cases.
If these are serious concerns for you, I’m sure you will always be able to find plug in electric grills on the market.
What’s so exotic about a composite pressure vessel? They’re already used in scuba and paintball.
Compress it to 10,000psi and it gets portable enough.
I don’t understand this suspicion. It’s easier to burn fossil fuels for electricity than to reform them into hydrogen.
If hydrogen is so difficult to bottle then how are there self-serve refuelling stations in operation?
Yes, there is a volumetric penalty, but it’s not that bad. At 10,000psi a 1 gallon hydrogen bottle has roughly the same energy as a 1lb bottle of liquid propane for camping.
Yes, but imagine a world where propane and other fossil fuels are no longer available. You’re going to lug a big battery around for an electric grill instead?
For what it’s worth hydrogen stations currently dispense at 10,000psi, which is considered “medium” pressure in the field. “Ultra high” pressure is considered an order of magnitude greater.
I’d much rather transport a bottle of hydrogen to a cookout than an electrolyzer. What if a power outlet isn’t available?
As Toyota has demonstrated (and speaking from my own experience), it’s not that tricky. As for cooking with the stuff, sometimes you just need portability and/or a flame. Electric is a poor choice in those cases.
That’s not such a bargain considering that it takes so long to charge a BEV. More fast chargers are needed to match the capacity of a hydrogen dispenser. I think the uneven subsidies and hype over the years have just lead to more BEV customers.
You’re correct. Maybe someone who does can explain the special appeal of a personal vehicle that requires 20+ minutes for a partial refill if you drive it too much.
The relative inefficiency is okay because it still produces hydrogen, which is better for transport applications than electricity in batteries. Plus, oxygen is a useful byproduct, which everyone seems to ignore.
As for the lack of hydrogen infrastructure, I think that has to do with it not getting as much support from the government. I couldn’t find a specific comparison, but the Wikipedia lists many more US programs supporting plug-in electric vehicles than ones supporting fuel cell vehicles. Apparently, Obama’s energy secretary, Steven Chu, was very anti-hydrogen and that’s just how it went.
We should be going full nuclear regardless in order to mitigate climate change.
Think about it. What are you supposed to do while you’re stuck charging for however long it takes? Scroll ads? Go spend money at a nearby business, hoping that you can get in and out before you get dinged for occupying the charging station for too long? Apparently, some charging stations even take reservations like Dorsia. No thanks!
Phone through one half of binoculars. Best I could do!
