This sentence really bugged me: > A Minnesotan wind turbine shows that wind energy can produce more than just electricity. No, it doesn't. It's just that electricity can be used to do lots of things, including splitting water as an input to ammonia production. What this article shows is that nearly all of the potential "shortages" in materials on earth are really just energy shortages (with some small number of notab…

Right. It also makes it sound like they’re not using the Haber Bosch process… but then: > Electrolyzers are located on-site.

It is literally the Haber-Bosch process, without question. The school actually calls it that in their own paper, https://cbsi-asabe.org/wp-content/uploads/2024/06/Harvesting..., because that is what it is.

I assume what confused the article is that ammonia plants often use natural gas, but that's purely as a convenient energy source and a source of hydrogen, so they cover both angles. But that isn't remotely a necessity.

With desalinization, in most places that is the case.

What I find funny is people that build machines that extract carbon from the atmosphere. None of the articles about it ever mention the energy cost in running the machine or howinell it could be scaled up to make a measurable difference.

But trees, for example, are 50% carbon, extracted from the atmosphere. And they're solar powered! And look nice.

Yes, absolutely. Look at places like Saudi Arabia and elsewhere in the Middle East that run on desalinization plants. It's energy, all the way down.

We have near perfect processes for saltwater filtering.

the talk about "electricity can do things" misses whats actually interesting here. Working in the energy sector, the hard problem is rarely generating the power, it is getting it into the grid. connection queue runs for years and turbines regularly get curtailed when the grid c anncot absorb more. A flexible load behind the meter, like an electrolyzer making ammonia on site, monetizes energy that would otherwise be wasted or never get built at all. The fertilizer is almost a side effect, the real product is a use for stranded wind. i would also add that wind + battery would be much better both for stablization and also the same use as mentioned in the article.

Even if carbon was a complete non-issue, electrification and a greater diversity of energy sources would still have immense value.

Electrification is a no-go when electricity prices keep going up up up.

“Plant more trees” won’t get you an IPO.

The price of grid electricity is moot when you're powering the process with locally generated green energy.
