The future is battery powered

I remember the Olden Times when Rush Limbaugh (may he Rot in Peace) would rail against solar power — what will we do when the sun goes down? — and wind power — what about calm days? — and tell us to keep burning coal and gas.

Technology marches forward, and now we have these things called batteries that can smooth out the highs and lows of electricity production. Now when we hear about solar farms going up, they’re usually accompanied by energy storage farms. Here’s what energy production in California looks like:

Solar power production is swelling during the day, and is extended into the peak demand period with batteries. Maybe they could also expand wind power, and possibly be better at conserving energy? I think if I plotted energy usage at my house, it would be much more uniform: we don’t have air conditioning, and I’ve done more cooking with an eye towards preparing meals that can produce leftovers that last a few days.

As it is, California is sometimes producing more solar energy than it can use. They have to throttle solar power output back, or even pay neighboring states to take it.

Good things are happening here in Minnesota, too. We’ve got a gigantic energy storage facility going up in Becker, a town between Morris and the Twin Cities.

One of the largest solar projects in the country is moving closer to completion, and it’s not in a famously sunny state like California, Texas, or even Florida. It’s in Minnesota, on former potato farms near the site of a retiring coal plant.

The Sherco solar and energy-storage facility will be the largest solar project in the Upper Midwest, and the fifth-largest in the U.S. by the time it’s fully completed in 2026. The first phase of the project should begin sending emissions-free electricity to the grid this fall, heralding the start of a new era in a state whose largest solar project until now has been just 100 megawatts. This new project will have a capacity of 710 megawatts. It’s being built by utility Xcel Energy, which will also operate the facility once it’s online.

The project is poised to deliver on the many promises of renewable energy: It will partially replace the nearby coal plant set to retire over the coming years, address the variability of solar power by pairing it with long-duration storage, and provide good-paying union jobs in a community that’s losing a key employer in the coal facility.

They’re using iron-air batteries, which are cheaper and less toxic and less flammable than the now-familiar lithium batteries. It’s also positive that this facility is going up explicitly to replace a coal plant, one we often saw as we drove along I-94. It hasn’t been so prominent in recent years, I guess they’ve been gradually shutting it down and we don’t see the giant exhaust plumes so much any more.

Goodbye.

Even closer to home, my university has begun a major energy storage project.

For many years now, UMN Morris and UMN WCROC [West Central Research and Outreach Center], have explored the potential of energy storage in rural Minnesota.

Now, UMN Morris and UMN WCROC are partnering to launch the Center for Renewable Energy Storage Technology, or CREST. In order to reach high levels of renewable power generation, efficient and economic energy storage systems are critically needed. This field is poised for significant growth and attention in the coming years. The new UMN intercollegiate Center will provide leadership in research, demonstration, education, and outreach in this vital field by organizing teams and partnerships and incubating energy storage research and demonstration-scale projects.

A hallmark and unique characteristic of renewable energy efforts at the Morris campuses has been the ability to test systems at commercial or near-commercial scales. This scale is especially crucial in moving new technologies from labs into the commercial market. CREST will also expand opportunities for Minnesotans to learn more about energy storage technologies and potential applications. Recently, UMN WCROC announced it will host the $18.6 million US DOE ARPA-E REFUEL Technology Integration 1 metric ton per day ammonia pilot plant. In addition, WCROC received $10 million from the State of Minnesota in the 2021 legislative session through the Xcel Energy RDA account to develop ammonia-fueled power generation and self-contained ammonia storage technologies. UMN Morris announced a new project to develop a large-scale battery-storage demonstration project. These projects are done in collaboration with partners from across the University of Minnesota and with many partners in the public and private sectors.

It’s too bad we can’t rub Limbaugh’s face in the progress that’s being made.

A spider banquet!

Now that spring is actually here — blue skies, balmy weather, all that stuff — and I no longer have classes to worry about, I’m getting back into the habit of going for a daily walk. As you might expect, I take this as an opportunity to look for spiders.

There is no significant spider presence yet.

However, as a portent for the future, look at all the spider food (some might call them mayflies) I spotted clinging to walls around town!

Big deal, you might say, I saw a few bugs. Let’s step back a moment and look at the big picture.

All those speckles and dots? Mayflies. The entire town is covered with mayflies. As I walked along, I could just put my foot on a patch of grass and a cloud of gnats, midges, and flies would rise up.

I’m hoping that this will be a great summer for spiders.

A frustrating news article

I read this article, “Where seas are rising at alarming speed”, with rising exasperation. Look: the Gulf Coast is slowly drowning at a rate that is now obvious.

It’s great at explaining how the consequences of climate change are harming people right now, and they’re only getting worse, but…WHY is the Gulf Coast in particular experiencing this rapid rise? The article doesn’t say. So I had to look elsewhere, like NASA.

Although the average acceleration of global sea level rise has also increased over the decades, it was mainly due to melting ice in regions like Greenland. For the Gulf Coast, the team used tide-gauge readings and satellite data from NASA missions like GRACE to rule out a few potential causes.

“We checked vertical land motion, for instance, and could relatively quickly say no,” he said. “We looked into the ice-melt component but it couldn’t explain the magnitude of the change that we have seen in that particular area.”

This left them with one other possibility: sterodynamic sea level, or the combination of ocean-water expansion in response to warming, saltiness, and ocean circulation. The team found that beyond Cape Hatteras, this acceleration extended into the North Atlantic and the Caribbean Sea.

But what is the source of this shifting circulation? According to Dangendorf, climate models reveal two factors at play.

“Approximately 40% of the acceleration that we have seen since 2010 can be attributed to man-made climate change, but there’s a residual 60% that we couldn’t explain with climate models,” said Dangendorf.

The remaining percentage was caused by natural wind-driven ocean circulation unique to the Southeast and Gulf Coast, the researchers found.

“It’s a region bounded by the western boundary current, or the Gulf Stream, so that makes it very prone to fluctuations and therefore we can see these massive changes on decadal time-scales,” said Dangendorf.

OK, now I can read the WaPo article without looking for a causal explanation, and truly appreciate how screwed the citizens on our southern coast are. It’s not just that the seas are creeping into their streets and basements, but that there are no practical solutions available — they talk about exorbitantly expensive pumps, but where are they pumping the water to?

Do I need to point out the irony of all those oil refineries on the Gulf Coast that are not being shut down, while proposing to build water pumps (that would probably be driven by coal and oil fired power plants)? That’s not to diminish the tragedy and struggle of all the people who have to deal with these consequences, but to point out that we need to stop thinking about stopgap solutions in the short term.

That’s no Franken-sheep

What do you think happened in a story with this headline, “Montana Man Pleads Guilty to Creating Massive Franken-Sheep With Cloned Animal Parts”? Oooh, Franken-Sheep and animal parts…were they importing chopped up bits of animal corpses and stitching them together to make monster sheep? The story continues:

An 80-year-old man in Montana pleaded guilty Tuesday to two felony wildlife crimes involving his plan to let paying customers hunt sheep on private ranches. But these weren’t just any old sheep. They were “massive hybrid sheep” created by illegally importing animal parts from central Asia, cloning the sheep, and then breeding an enormous hybrid species.

The “animal parts” are whole, intact embryos of Marco Polo sheep, a very large species, and then raising them to adulthood. He was basically smuggling in embryonic sheep, nothing particularly radical scientifically.

Once Schubart had smuggled his sheep parts into the U.S., he sent them to an unnamed lab which created 165 cloned embryos, according to the DOJ.

“Schubarth then implanted the embryos in ewes on his ranch, resulting in a single, pure genetic male Marco Polo argali that he named ‘Montana Mountain King’ or MMK,” federal authorities wrote in a press release.

Then they collected semen from the adult sheep, and crossed them to domestic sheep, again, not at all radical scientifically. Somebody tried to jazz up the story with talk of animal parts and Franken-sheep, when it’s really a story about illegally importing an endangered species from its native range, and hybridizing them to produce a stock for profit. The story is bad enough without stuffing it full of misleading pseudoscience.

At least the guy behind the scheme got his comeuppance.

Schubart pleaded guilty to violating the Lacey Act, and conspiracy to violate the Lacey Act, which makes it a crime to acquire, transport or sell wildlife in contravention of federal law.

“This was an audacious scheme to create massive hybrid sheep species to be sold and hunted as trophies,” assistant Attorney General Todd Kim from the Justice Department’s Environment and Natural Resources Division said in a press release.

“In pursuit of this scheme, Schubarth violated international law and the Lacey Act, both of which protect the viability and health of native populations of animals,” Kim continued.

Yeah, and that’s the extra ugly twist here. They weren’t doing this to help the species — they were raising great big sheep on ranches so big game hunters could pay big money to shoot a large animal. On a farm. You know, real sportsman-like.

Today is climate change day in the classroom

As I’ve mentioned before, one of the things I’m doing in my Eco Devo class is to throw more of the burden of learning on the students. It would be too easy for me to just get up and lecture, telling them what they should know, and it is often hard for me to just shut up and let the students talk. I’ve split up the course so that Monday is when I start talking and dominate the classroom, Wednesday I ask the students to answer questions about Monday’s lecture and the book chapter, and on Fridays they’re given a paper to analyze.

This week’s paper is Morphological plasticity of the coral skeleton under CO2-driven seawater acidification by Tambutté and others. The context is that we’ve been talking about cellular physiology and development, and responses to environmental stresses, so I figured a primary research article about the effect of rising CO2 levels would be appropriate.

(Answer: more CO2 is not good for corals. Decreasing pH leads to a cnidarian version of osteoporosis.)

Are wind farms killing whales?

Potholer54 always does skepticism well. Here, he’s looking into the claim that whale deaths are correlated with the presence of wind farms, and the answer, in short, is “no.” Although industrial noise is uncomfortable/stressful for whales, it’s not just wind farms that we should be looking into.

It’s also a thorough exposé of Michael Shellenberger. Shellenberger doesn’t understand what “correlation” means, he’s selective in his choice of causes (windfarms bad, oil exploration good), and he’s an expert in the conservative shell game of hiding the sources of his funding. Don’t trust a thing that man says.

You will not be surprised to learn that he is currently the CBR Chair of Politics, Censorship and Free Speech at the University of Austin. Yeah, that University of Austin. He claims to be an “environmental activist,” but he’s not — he’s a right-wing shill for the oil industry.

For us pescatarians

I would murder that table

I’m a lazy vegetarian — I’ll sometimes eat chicken or red meat in small quantities if I’m traveling or a guest in someone’s home (my scruples weigh less than putting a burden on someone else), but that doesn’t happen often…once every few months, maybe? But on one thing I do not compromise: I love seafood. I’d eat it every day if I could. I guess that makes me a pescatarian rather than a vegetarian.

So this is handy. The LA Times has an article on ethical seafood consumption, and it links to the Monterey Bay Aquarium’s Seafood Watch, which lists all the varieties of seafood and whether they were ethically caught and managed.

A lot of it is about the source. Don’t buy fish from Chinese factories — they basically employ slave labor, overfish, and leave a trail of dead bodies behind them. Don’t eat fish caught by trawling, which damages the environment…and Americans and Canadians are guilty of that. Most of the recommended fish and shellfish are farmed. Unfortunately, most of the seafood we buy isn’t labeled with the method of capture — cod is OK if caught on a pole&line, not so ethical if dredged up by a trawler. That’s not on the label, though!

Also, it doesn’t help that a lot of the responsible farmed seafood are molluscs & shrimp & squid, which I’m very fond of, but gives my wife the heebie-jeebies. I can only eat weird marine invertebrates when she’s not around, and she’s almost always around. I guess I’m insufficiently dedicated to my food, because I’d rather have her in the house than a bucket of clams…

Mmmmmm. Big bucket of steamer clams, with some crab on the side, and calamari, and a salmon fillet…

“Killing salmon to lose money deserves a deeper analysis”

In Maine, there’s an effort to put into practice traditional indigenous methods of land management. This sounds like a smart idea to me — ask the people who have lived there for centuries what works, and try that.

Meanwhile, traditional tribal practices have often proved the most sustainable way to manage natural resources. Prescribed burns ­­in forests carried out by generations of­­­ Native Americans in the Klamath Mountains in California, for instance, have prevented destructive wildfires better than European settlers’ methods, which suppressed fire and let forests grow too dense. More wildland managers and scientists in North America now recognize the need for prescribed burns, but they still are not being carried out enough to prevent catastrophic fires.

For decades, tribal members in Maine advocated bringing down Penobscot River dams that once powered saw and paper mills to restore an Atlantic salmon fishery. The Penobscot method of timber harvesting, which leaves 75- to 100-foot buffers of trees around rivers and streams, creates ideal conditions for salmon. Salmon like to spawn upriver in shady pools, created by allowing the forest at a river’s edge to thicken and birch trees to fall into it. One afternoon in late October, I watched Penobscot tribal members and scientists from Maine’s department of marine resources release into the Penobscot watershed 80 adult salmon that the state agency had raised in a hatchery, in the hope that they would spawn in such pools and help restore the historic salmon population.

Ah, the salmon. I grew up near a river that used to be thick with salmon, and my childhood was spent watching the fish slowly fade away, and seeing my father growing increasingly frustrated and depressed about it. The rivers were overfished and abused, and steadily declined in productivity. Gosh, maybe we were doing something wrong.

My father, with salmon, in the 1950s

When we lived in Eugene, Oregon, we were just a few blocks from the Willamette River (hint for non-natives: it’s pronounced will-LAM-it, emphasis on the second syllable), and it was a very pretty river, but we never bothered fishing it. I’d occasionally see fly fishermen working it, but nobody was hauling 20 pound silver salmon out of its waters that I know of. Part of the reason was that it was extensively dammed upstream, and as everybody knows, the salmon life cycle requires swimming upstream to spawn, and then the young fish have to navigate downstream to the ocean to mature. Dams kind of get in the way.

But don’t you worry! The Army Corps of Engineers has come up with a solution for the Oregon salmon fishery!

To free salmon stuck behind dams in Oregon’s Willamette River Valley, here’s what the U.S. Army Corps of Engineers has in mind:

Build a floating vacuum the size of a football field with enough pumps to suck up a small river. Capture tiny young salmon in the vacuum’s mouth and flush them into massive storage tanks. Then load the fish onto trucks, drive them downstream and dump them back into the water. An enormous fish collector like this costs up to $450 million, and nothing of its scale has ever been tested.

The fish collectors are the biggest element of the Army Corps’ $1.9 billion plan to keep the salmon from going extinct.

Yikes. You know, salmon can swim. They’ve been doing it for millions of years, quite competently, until humans started planting great big obstacles in the way. You could just shut down the dams periodically, and let them do what comes naturally, but no…we need a plan that involves fish vacuums and big trucks. They think they’ve got a good reason for that.

The Corps says its devices will work. A cheaper alternative — halting dam operations so fish can pass — would create widespread harm to hydroelectric customers, boaters and farmers, the agency contends.

Moreover, many of the interests the Corps says it’s protecting maintain they don’t need the help — not power companies, not farmers and not businesses reliant on recreational boating.

The Corps’ effort to keep its dams running full-bore is a story of how the taxpayer-funded federal agency, despite decades of criticism, continues to double down on costly feats of engineering to reverse environmental catastrophes its own engineers created.

The only peer-reviewed cost-benefit analysis of the Willamette dams, published in 2021, found that the collective environmental harms, upkeep costs and risks of collapse at the dams outweigh the economic benefits.

This looks like an expensive solution looking for a problem, after years of amplifying the problems that they created. There is already a simpler solution at hand, but it wouldn’t justify the Army Corps of Engineers spending nearly $2 billion.

There is a simpler way to protect fish: opening dam gates and letting salmon ride the current as they would a wild river. It costs next to nothing, would keep the Willamette Valley dams available for their original purpose of flood control and has succeeded on the river system before. This approach is supported by Native American tribes and other critics.

The Corps ruled it out as a long-term solution for most of its 13 Willamette River dams, saying further reservoir drawdowns would conflict with other interests.

The debate and the consequences of the decision are real for the Confederated Tribes of the Grand Ronde, who have fished the Willamette for thousands of years. Grand Ronde leaders said they’ve met with the Corps seven times to spell out potential alternatives to building giant fish collectors and maintaining hydropower.

“They always feel like they can just build themselves out of problems. And this is really something that we don’t need to build,” said Michael Langley, a former tribal council member for the Grand Ronde.

The fish would flourish, but the recreational boaters would “suffer.” I say fuck the boaters, I support the fish.

The native American tribes know what’s up, and delivered a pithy, if understated, summary.

The tribes filed a letter with the Corps in February that included a pointed summation: “Killing salmon to lose money deserves a deeper analysis.”

For now, though, we’re stuck with a bureaucracy that can’t see clearly, because they’re so wrapped up in technological solutions that make the problems worse…but increase the power of the bureaucrats.

Former employees and scientists who’ve worked closely with the Corps say its officials are afraid to change because drawing down reservoirs and eliminating hydropower would call into question the agency’s usefulness in the Willamette Valley.

“They don’t like to be seen as an agency that can’t execute,” said Judith Marshall, who spent six years as an environmental compliance manager for the Corps.

Marshall, whose work included projects in the Willamette Valley, filed a complaint with the federal Office of Special Counsel in 2017 alleging the Corps ignored obligations under federal environmental laws.

“They’re some of the smartest people I’ve ever encountered,” Marshall said, but “they’re so wound up in their models and what they’re doing, like they can’t see the forest through the trees.”

They’re not thinking old enough. Go back further than solutions dreamed up in the 1930s and examine solutions that were tested in the thousands of years before that.

It would have made my father happy.

Am I turning into a Midwesterner? Scary.

I grew up in the Pacific Northwest, and nature to me was towering red cedar trees draped with moss, and rocky beaches covered with sea anemones and urchins. These things are not present in Minnesota, and I miss them. Bland fields of corn and soybeans are boring, completely lacking in majesty and complexity. I used to dream of retiring to some battered old seaside town in my old age, escaping the dreary farm fields of the Midwest.

It’s not happening.

But after nearly 25 years of living here, it’s beginning to grow on me. Focusing on native arthropods has helped, and the realization that this place shouldn’t be about corn is also liberating. The prairie is deeply interesting…it’s just that cornfields are not the prairie. They’re the antithesis of prairie. Getting down close and peering into a mess of wild plants while looking for spiders is enlightening.

Also, I’m really liking this guy. The enthusiasm is infectious. We’ve got a vigorous stand of native prairie plants growing right outside my lab window, and it’s got me thinking that, when the fall is a little further along and the pods start to dry out, I might harvest a few seeds and pot a few at home, or scatter them in my yard.

That bit of restored prairie looks so much nicer than the impoverished lawn surrounding my house.
