Hydrogen is pretty much the only one that really works. It allows you to store energy for months on end, or ship/pipe it around for thousands of miles.

You basically just reinvented the bus/taxi...

Which is why BEVs aren't the future.

Hydrogen cars are basically EVs without the giant battery. So it neatly avoids the huge cost and weight problem. Which is why Toyota thinks they are the future.

A lot of those "agnostic" sources are secretly working for the BEV companies. There's a lot of misinformation out there. Anyways, given that a fuel cell is vastly more efficient than a conventional ICE, there shouldn't be an issue on efficiency. FCEVs are more than good enough. Anyone bringing this issue up as a problem is either confused or has an agenda. After all, FCEVs are also EVs.

Gas stations are much cheaper than battery swapping. In fact, that is the main argument in favor of FCEVs. Replacing existing gas stations with hydrogen stations is a much cheaper solution than putting up millions of charging stations, battery swapping stations, DC fast charging stations, etc.

I'm on Kbin FYI. It mostly works for my needs.

Excess green energy will likely flood the system. We will have an overabundance of all types of green energy, including hydrogen, in the long-run.

Critics of hydrogen are basically contradicting themselves. If you admit the need for energy storage in the form of hydrogen, you are also admitting the existence of very cheap hydrogen. That will be available for a variety of tasks. It will become the go-to solution for anything that needs a chemical fuel. If it is cheap enough for heating or steel production, it will be cheap enough for transportation solutions too.

Yes, you should read up on salt cavern storage: https://www.pv-magazine.com/2020/06/16/hydrogen-storage-in-salt-caverns/

For millions of people, that is not an option. And I'm assuming you mean "BEVs" not electric vehicles. FCEVs are also electric vehicles. Furthermore, the claims of the BEV industry are not to be trusted. It is no different than citing the oil industry's claim that BEVs cost the the equivalent of $17/gallon to drive.

Battery swapping will explode the logistical and resource requirements of BEVs. It makes the problem even worse.

Airplanes will probably use some combo of e-fuels or LH₂ setup. The latter is doable via a new type of airframe like a blended wing body.

If speed is important, you'd support the rapid adoption of hydrogen, not oppose it. These are not credible arguments unless you do not actually believe in climate change.

Renewable energy is leading to vast curtailment and excess production. That energy is pretty much wasted. Turning it into hydrogen will not cost that much money nor require that much more generation capacity.

Large scale storage of hydrogen is done with natural occurring salt caverns. These cost far less than just about anything else ever conceived.

Again, if the goal is to phase fossil fuels, you would go hard in favor of green hydrogen, alongside many other ideas. You would not oppose any green energy ideas.

If you are totally honest, you'd admit that for a huge percentage of the transportation, we don't have any real option other than hydrogen. That's certainly the case for many types of commercial vehicles, ships and airplanes. But it is also true for a large percentage of passenger cars. Not everyone can accept a battery powered car in their lifestyle. So it is inevitable that transportation is part of what hydrogen is good for. And once we start using hydrogen for this, batteries quickly become the odd-man out. After all, why spend trillions on a highly destructive and arguably unsustainable technology that will have to be replaced anyways?

The reason why it is a climate change denial tactic is that it completely ignores the fact that we can easily build enough renewable energy for pretty much whatever we want. It is thousands of times more plentiful than fossil fuels, and won't run out either. So even if we accept your claim of needing 3x more capacity, that is still no problem. However, it won't actually need that, since renewable energy requires vast amounts of energy storage to be viable. That storage is most easily done using hydrogen. So in reality, hydrogen is pretty fundamental to renewable energy altogether.

There's a good chance Cruise will land someone in jail. And frankly people should go to jail over this.

This is anti-hydrogen propaganda. It is basically a marketing spiel for the battery industry. In reality, hydrogen is going to power nearly all transportation, mainly because batteries are not a sustainable solution.

And the notion that we can't build enough renewable energy capacity is a classic climate change denial argument. People who say this are unknowingly (or sometimes knowingly) trying to get everyone back onto fossil fuels.

That's effectively been rescinded. It will likely be formally rescinded at some point.

We're slowing turning smartphones into dumbphones again. Many of us used to rock 10+ year old phones, since phone calls and texting doesn't need anything fancy.
