This idea allows for relatively easy extraction of hydrogen. Extraction of hydrogen from water is extremely endothermic and would not constitute a real way of storing hydrogen.

That is, at present, equal to 3.0734 US Dollars.

They are failing at basic editorial controls. This is not a “pretty good fucking job.” It is a sign of real decline.

It’s one of the stages of enshittification. Unless we see hard changes to avoid further decay, Ars will inevitably get worse and and worse until it does become an “internet rot site.”

Which is why Discord should die. It made the Internet much less accessible.

Ok, in that case, we should call it “new comments.”

It could be liquid hydrogen though.

Hydrogen is lighter than air, which means that any fire would be much more brief and hard to sustain.

Not anymore than any other fuel.

It is a huge greenwashing exercise in reality.

It is storing hydrogen in metal hydrides which is very safe.

You should actually try to read the article.

These use green hydrogen.

Those are outright lies. For one thing, you can use fuel cells instead of gas turbines, getting rid of NOx emissions entirely (not to mention you can filter out NOx even with gas turbines).

Sorry, but this conversation cannot continue if you proceed with dishonest arguments.

If you adopt hydrogen for energy storage, you no longer have to worry about “where.” You have a solution that is nearly geographically independent.

The more renewable energy you have, the more you need long-duration energy storage. You cannot reach 100% renewable energy without huge amounts of it.

For a few hours, yes, but that will make up a small percentage of total energy stored. To really solve the intermittency problem, you will need large scale energy storage.

just use excess electricity to make hydrogen. This actually solves the intermittency problem, among many other things that will require hydrogen in order to reach zero emissions.

I hope people here are realizing that our current strategies are not working. They are mostly just “feel-good” solutions like paper straws, and will not eliminate the need for fossil fuels. Which is why I keep pushing for green hydrogen, because I already knew this and want real solutions to be pursued.

The first point to make is that hydrogen is not decades off. Green hydrogen is happening now, and its production is rapidly expanding alongside the expansion of renewable energy production. Many sectors can rapidly adopt green hydrogen right away. This is similar to the conversation we we had about solar power about a decade ago. Critics of solar power back then were being Luddites (and sometimes secret fossil fuel industry stooges). They were convinced that solar could not be cost-effective or scale, based off of very outdated understandings of the issue, but they were wrong. This conversation is repeating with green hydrogen.

On a related note, pro-electrification crusaders are being hypocrites on this subject. They themselves are demanding that we wait decades for miracle batteries or multi-decadal long electrification programs. Because they want “perfect” solutions rather than “good” solutions. A good example is how they demand we fully electrify all rail, a process that will take decades, rather than doing something faster like switching diesel trains to hydrogen trains. In reality, adopting hydrogen now, alongside more reasonable forms of electrification, will be a faster path for reducing CO2 emissions.

Also note that most “fearmongering” types of argument against hydrogen originated from the fossil fuel industry. They are always spreading propaganda intended to undermine green energy projects, and make similar claims about all green technologies. Claims that hydrogen is dangerous, or a GHG, or will leak, etc., are all fear tactics created with minimal amounts of evidence. In reality, hydrogen has very few problems, and adopting it will drastically make transportation and industry safer and more green. It is unfortunate that many environmentalists have fallen for this tactic, but I suppose every green idea had to overcome it.

Finally, you can buy hydrogen and hydrogen-related products. Sure, we are still a bit early on the adoption curve, but that is true of every new idea. Someone can buy a hydrogen car, or a furnace, or whatever right now. Many more are also capable, but don’t know it yet. So rather than demonizing something for not being able to basically time travel, environmentalists should promote green ideas in order to accelerate their adoption.
