> 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 notable exceptions like helium), and the reason electrification is so important is because it allows faster replacement of fossil-fuel generation with carbon-free sources.
No it's not. That's not the equation. The only thing that matters is the final cost, including capex.
Utilities are pooling the wool over the eyes of PUCs and the media is not doing what it needs to show how the utilities are screwing customers because the media is illiterate...
But what China and other places (eg Spain) for this sort of ammonia is to place generation and batteries right at the ammonia site, bypassing the grid for most of their energy, dramatically lowering costs.
The grid costs more than electricity generation, and utilities get guaranteed profit on grid costs, so they try to make the grid as expensive as possible, even as renewables and storage are lowering the cost of generation.
Right. It also makes it sound like they’re not using the Haber Bosch process… but then:
> Electrolyzers are located on-site. They use wind energy to split water into hydrogen and oxygen gas.
> Additionally, nitrogen gas is directly harnessed from the atmosphere using an air-separation unit.
> Hydrogen and nitrogen are combined under pressure, resulting in carbon-free ammonia fertilizer.
That sounds a lot like the Haber Bosch process to me. So they’re just saying, rather than divert excess generation to a battery, you could instead build a micro H-B plant on site to produce ammonia.
I doubt this makes any sense in the grand scheme of things as you achieve major efficiencies at scale for chemical plants. Makes more sense to just electrify existing ammonia plants and ensure they use renewable electricity sources.
The green chemistry industry is full of penny-wise pound-foolish concepts like this and it drives me absolutely nuts.
From doing a bit of digging into this myself after hearing it being promoted on the radio, I both agree and disagree. Working through the $/acre for on-site produced ammonia using locally-generated electricity (I forget if I was looking at PV or Wind, doesn’t matter) the payback period was surprisingly quick, like 2 or 3 years. One of the big reasons is that you don’t actually need a very big system; you only need on-farm ammonia a few days a year but you have all year long to harvest and store enough for those few days.
Then you have 1,000 separate ammonia generation systems that need upkeep, repairs, etc. It is doing chemical reactions under pressure to produce presumably ammonium nitrate which is explosive. The engineers you would need probably aren’t cheap, and storing large quantities of ammonium nitrate all year is sort of sketchy. Timothy McVeigh took out an entire federal building with about 4800 pounds of the stuff mixed with car fuel.
It’s usually a lot cheaper and safer to condense all that demand into a purpose-built facility where they can hire an engineer to look after all the generation, have centralized container storage, backup parts, etc.
None of that prevents putting the panels or windmills on farmer land, though. You could imagine some sort of “get a discount on ammonia if we can put a solar panel in your field” scheme. Or, even more simply, put up your own panels, sell the power back to the grid, use that money to buy fertilizer from the factory buying your power off the grid.
I don’t know the exact process but I don’t think ammonium nitrate actually gets involved. The system I was looking at (Green Lightning) actually doesn’t make ammonia but rather liquid nitrogen fertilizer
Plasma to take N2 + O2 -> NO2 and NO gas
The NO and NO2 are dissolved in water to become HNO2 and HNO3, which then become NO2- and NO3- ions in the water.
It’s a low pH solution which stabilizes it and then you dilute right before application so that you don’t burn the crops.
There's a lot of places in the world where there's room for wind but the grid can't transport it to a user. In that case consuming it locally would make sense, and especially fertilizer is a very energy heavy product.
So it might be easier to pipe the ammonia to wherever it's needed? When it's in ammonia form the energy is essentially stored for a long time.
I don’t think this is true, but it’s not my forte.
Pure ammonia is toxic to animals. At normal outdoor temperatures it also only becomes a liquid at ~100 PSI (it’s like 150 at 80F). The boiling point at STP is like -27F.
I’m doubtful running a power transmission line to these places is harder than maintaining pipes that transport either a toxic gas, or a toxic pressurized liquid.
If you could turn it into ammonium nitrate, that’s a solid at room temp and easier to transport. It’s explosive but insensitive so it shouldn’t without another explosion first. Even if it does, this sounds remote enough that it shouldn’t matter and ammonium nitrate is a no -toxic fertilizer. Wildlife shouldn’t even notice.
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.
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.
>That sounds a lot like the Haber Bosch process to me.
Well, kinda. But Haber-Bosch uses an iron catalyst. This is cheap, but it requires very high temperatures and pressures. There has been some recent work on ruthenium catalysts (particularly a Japanese company Tsubame BHB) which are more expensive, but allow the reaction to proceed under milder conditions. A particular goal is to have smaller facilities which can then be colocated with power generation. So you are exchanging a higher fixed cost for hopefully lower variable costs. I don't know if that's actually what they're doing here, though.
Not to mention ammonia isn't the friendliest of chemicals and doesn't exactly beg for decentralized logistics.
I think, projects like these grew out of dunkelflaute moral panic regarding renewable energy. Meanwhile grid battery storage has becomes cheap enough to completely obliterate this concern.
And quite frankly, fertilizer needs in agriculture should be addressed by ecological means anyway. If we want to lower the impact of climate change, we need to get out of this "just throw more energy at it" technology mindset.
Here in Germany we have up to three months of almost zero solar production in winter due to foggy conditions (measured from my own solar inverter). It is not feasible to store summer electricity until winter in batteries. Batteries have self-discharge and would be hilariously expensive per KWh if they only cycle once a year. Chemical storage is probably the way to go here at least, and hydrogen can be used for many other useful things than just heating or running power plants.
Although there are many sunny countries where solar + one or two days of battery storage are probably enough for the full year.
> 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 notable exceptions like helium)
You're saying freshwater shortage is really just an energy shortage?
Even in the middle of the Atacama, it's still just an energy problem. The Atacama basically borders the Pacific, so it's just a desalinization and transport issue, which is, again, all just energy.
It's not so much unavoidable as one of the things we're doing already with grey hydrogen (made from methane). It's about cleaning that up and using blue (grey with carbon capture) or green hydrogen, not finding new uses for ammonia (like using it as a fuel for e.g. shipping). Micheal Liebreich does a great job in his podcasts and articles explaining how that would be economically extremely unrealistic.
For ammonia specifically, cleaning that up requires energy that is equal to about 5% or so of global electricity production. A few petawatt hour basically. To produce around 190 million tonnes of ammonia. This setup in Minnesota is cute but it's a tiny little drop in the ocean in terms of what would be needed. It does about 1 tonne per day.
They haven't really solved or proved anything that we didn't already know. Yes you can make ammonia with electricity. Amazing. It's just that you need a ginormous amount of windmills to get to what is needed. It's doable but we're talking hundreds of thousands of windmills.
And that's just the tip of the iceberg. A lot of the other hydrogen based technologies up the same ladder that this website reports on / promotes, would need even more windmills, nuclear plants, perpetuum mobile machines, etc. to generate the stupendous amounts of power needed to produce all the hydrogen needed.
What Liebreich does with his ladder is making the simple point that even just converting what we currently do with grey hydrogen (i.e. mostly ammonia) to green hydrogen is going to be a decades long project.
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.
A nice thing about the fertilizer is that it is only needed for a few weeks out of the year, which means it can be produced intermittently and stored without causing problems. If there are two weeks of non-production due to weather that isn't an issue so long as it averages out over the year. One could imagine a plant that only runs when the electricity is almost free.
> This process is extremely heat-intensive and accounts for up to 2% of total global greenhouse gas emissions.
> While it is highly unsustainable, it has doubled the Earth’s food-carrying capacity and still feeds almost 50% of the population.
2% greenhouse gas emissions to feed 50% population is unsustainable? What?
> The key is to create synthetic ammonia fertilizer by combining atmospheric nitrogen with natural gas or coal.
> Synthetic fertilizer is traditionally created in chemical plants that require continuous, high-volume power. This is why producers remain reliant on fossil fuel-powered grids.
What, again? Haber-Bosch process requires continuous power doesn't mean it's natural gas or coal. Where is nuclear? Is solar/wind disrupt that much that it can't compress/heat up some gas??
> 2% greenhouse gas emissions to feed 50% population is unsustainable? What?
Eventually you cook everybody and the population drops to 0. We want to maintain the "feed everybody" aspect while eliminating the "continually add excess carbon to the atmosphere and render the planet uninhabitable" aspect.
Haber-Bosch require continuous input of hydrogen, but aside from that it is a net source of power. The reaction is exothermic and can provide more than enough work to drive compressors that pressurize the reactants.
TIL the Red Pyramid looks remarkably like the Haber-Bosch ammonia production process. And the word "Amun" is the etymological root of the word Ammonia.
I work with a company that produces ammonia from local waste streams. The current policies and war has really hurt farmers. Certain fertilizers and other inputs have more than doubled in price, if they can even be found anymore.
Sounds like an opportunity to scale up your business. If the competition suddenly gets expensive that is a market opportunity.
Of course it's never that simple. If the war ends tomorrow and fertilizer prices drop back to normal over the course of the next two years an expansion could find itself uncompetitive just as its coming online.
We are expanding and we’ve ensured our loyal customers remain supplied! Because of our waste processing ability I’m not worried about competition, it’s a fundamentally different value prop than Haber Bosch.
A loop where solar is converted to fertiliser using similar process , probably generating hydrogen as a side effect with some mechanism to probably capture some carbon for economically useful use when it reaches say an LCOE of 0.01 $/kwh and done on mind boggling scale might actually be the holy grail solution to a lot of problems at the same time. Might need quite a few breakthroughs in the material science scheme of things though. There are good reasons why hydrogen has never really taken off by itself even with so much scale, innovation thrown at it so far. The best hope is China doing to hydrogen now what it did to solar in 2010s.
I would prefer to have figures how this compares to the traditional Haber-Bosch-process, how much energy is put into this, and how much fertilizer do we get for it, if it's just a PoC without evaluation of how much energy is used. in this whole process we got nothing NB: to beat Haber-Bosch you don't need much. it isn't only about the produced carbon dioxide
Some will criticize renewable energy because the power output is spiky. This sort of thing is why that doesn't matter. There are plenty of things you can do with excess power. There's been research in manufacturing gasoline from the air. It's not economical to do for its own sake but when we're talking about excess power, that's not really a factor. Fertilizer is a new one (to me). But it makes sense. You'll still need phosphorus (phosphate) from somewhere.
Thought about something similar a few months ago, love seeing it in action. The article was terrible however, dunno why every other sentence is bold. Genuenly feels like I'm reading a middle schooler trying to fulfill a word usage/sentience structure quota.

Also it doesn’t need to, wind energy was used to produce shit before electricity was harnessed!
Sailboats are harnessed wind energy and some 10kY old. Windmills and wind pumps were invented some time between 700 and 900.
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.
No it's not. That's not the equation. The only thing that matters is the final cost, including capex.

The price of grid electricity is moot when you're powering the process with locally generated green energy.
Tell that to struggling family’s electric bills

It eliminates the need to connect the turbine to the grid.

“Plant more trees” won’t get you an IPO.
Finding a way to make money by capturing CO2 will get you an IPO. The technology you use is only of secondary concern.
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.

You're saying freshwater shortage is really just an energy shortage?
Are you saying it isn’t?
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.
Unless you're in the middle of the Atacama or on the moon or something, yes.
Even in the middle of the Atacama, it's still just an energy problem. The Atacama basically borders the Pacific, so it's just a desalinization and transport issue, which is, again, all just energy.
With desalinization, in most places that is the case.
We have near perfect processes for saltwater filtering.
I read that article. I don't know why. It was a difficult read.
Nearly every sentence has a bold-face phrase. There are no paragraphs, only sentences. It is borderline incoherent and very off-putting.
That style article needs to eliminated. Surely there is a better information source for this site and process than this online rag.
Kinda looks like a low-quality executive summary of a longer text. I agree, it's garbage.

In other news, wind mills have been used to produce lots of other things that require electricity.
As well as tons of other things without electricity involved at all! Don Quixote was never in fear of being electrocuted.
In other news, no whales were bothered by this windmill, either.
We need to hurry and kill this tech before environmentalists try to make other fertilizers illegal and cause mass famine.
