@steve This is just BEV propaganda. There is very little difference in efficiency comparing BEVs to FCEVs.

This becomes more obvious when you realize that BEVs cannot magically absorb energy made from wind and solar. You need a purpose built grid, one with huge amounts of energy storage, to be able to reach 100% renewable energy. But that requires hydrogen as part of the grid. So efficiency is not as high as you think.

Californians are buying fewer Teslas in what could be a bad sign for Elon Musk

@quixoticgeek Please don't do revisionist history. You were clearly caught making a fundamental error. You did not know about thermally-driven heat pumps at that moment.

So you unknowingly passed off corporate propaganda as if it were fact. Someone showed you your mistake, at which point you threw a fit. A more reasonable response would be to admit that thermally driven heat pumps exist too, and that your past statements should be adjusted to reflect that knowledge.

@quixoticgeek Except you clearly stated that hydrogen for heating was a "unviable". You outright called a distraction by fossil fuel companies for politicians. Then went on rant about how many times more efficient heat pumps. Completely unaware of thermally driven heat pumps.

This is all out in the open. It's not like you can deny what was posted online.

Prospectors hit the gas in the hunt for ‘white hydrogen’

The zero-emission fuel may exist in abundant reserves below ground. Now large sums are being invested to look for it

@feld We also live in a world of fraudsters and liars. This includes the website in question, which just seems to be anti-#hydrogen propagandists.

Also, why even bother with battery trains if you have catenaries anyways? It just seems like an example of subsidy fraud.

@feld @tk @akorenchkin As the scale we're talking about, there will never be enough transmission lines, nor will there even be demand for it on the other end.

You need energy storage too, and #hydrogen is the ultimate form of it.

And you are forgetting your own words: Saltwater electrolysis is totally possible.

@feld @tk @SlicerDicer @akorenchkin Again, we have basically infinite energy for this. We can easily replace oil if we wanted to.

@feld @tk @akorenchkin The amount of available energy from renewables is many orders of magnitude greater than global energy consumption. This is not a problem. Nuclear is also easily scalable because it needs very little fuel. Uranium + reprocessing completely solves that issue too.

The energy breakthrough you're looking for already has happened. You're just in denial about it.

@feld @tk @akorenchkin That's totally false. The main problem is that we curtail large portions of wind and solar. The problem is overproduction, not underproduction. That gives us free energy to make green #hydrogen.

@feld @tk @akorenchkin Electrolysis of water from green energy sources. It can be anything. It is literally the same marketing spiel as what BEVs promised: The energy source is now fully agnostic and can be anything.

And yes, one very smart idea seems to be seawater electrolysis. It can be done entirely off-shore:

@feld @tk @akorenchkin That's the same dilemma as a battery. It is energy storage, not a new energy source.

@feld @tk @akorenchkin

We are seeing big leaps in electrolyzer capacity. That is a sign that green #hydrogen production is currently happening and rapidly expanding.

@feld @tk @akorenchkin You are simply not up to speed to the world right now. Green #hydrogen production already exists right now. It is rapidly coming down in price and billions are being poured into the technology. You are just getting a wake-up call that it is no longer 2010 anymore.

@feld @tk @akorenchkin So in your world, the post-BEV world will be powered by something with even worse energy density...

I'll believe in synfuel powered ICE cars before that. And because #hydrogen is truly sustainable, it is guaranteed to play a role. People who doubt this are rejecting obvious real-world advancements while simultaneously imagining fantastical leaps in highly speculative technology. It is unlikely, and more than anything else just a sign of wishful thinking.

@feld @tk @akorenchkin That's well beyond a decent sample size. You're being as dishonest as anyone possibly can.

No, YOU STOP BULLSHITTING. You are a fucking Luddite by acting like this. Time to stop being a stooge of the BEV industry and realize there are many ideas out there. The BEV will not be the final destination of the car. You need to stop being permanently stuck in 2010.

@feld @tk @akorenchkin Great! Then admit there's also no problem with #hydrogen cars because they are also tested to a high degree! There are no longer such risks!

And again, there is minimal fire risk. Hydrogen floats away fast and poses a minimal fire risk even in a leak situation. You are safer in a hydrogen car than a gasoline car.

@feld @tk @akorenchkin It is designed for 15 years of life even under heavy usage. For most cars, they're pretty much guaranteed to last the lifespan of the car.

And if you're going to talk about this subject, you should also be aware of the lifespan of li-ion batteries. At some point they are also a fire danger.

@feld @tk @akorenchkin Hydrogen tanks are tested to 22,000 cycles. They likely exceed the expected lifespan of the car.

@feld @tk @akorenchkin They're already thousands of carbon fiber tanks being used all the time. There are no known issues according to the engineers that build them. You are just being a Luddite here.

A battery fire is actually the biggest danger among them all, mainly because it burns so much longer than anything. It also can't be put out with water. Again, more fearmongering from you and you are just repeating BEV propaganda.
