Climate in the 21st Century

[printer]

Batteries are on the way and several different chemistries are being offered. It is not what is avail right now that will make the biggest difference, but what will be over the next 5 or ten years and current lithium chemistries won't be around forever, they will be supplanted by others. I post articles with links to the papers they are based on too and videos for general consumption that are not really that speculative as I try to stick to things we might see in 5 or 10 years. This thread is more about information to base policy on, the science is often linked to for those who can digest it.

Right now, a limited number of lithium chemistries are in wide use, and these have issues with safety and longevity, but practical advances and improvement to even these are made regularly. I hope you don't consider MIT to be too speculative?

What’s next for batteries

Expect new battery chemistries for electric vehicles and a manufacturing boost thanks to government funding this year.

And we have been 5-10 years away from groundbreaking battery tech for the last 20 years.

the physical limitations of how much energy you can safely transfer to the battery in 3 minutes or even 10 minutes.

Ah ok, but that‘s faster than both fast charging and ultra fast charging. Or as the Brits say, ultra rapid, “Rapid charging = 50 kW - 149 kW. Ultra-rapid charging = 150 kW+“. In EU anything above 22kW is a fast charger, typically 43,50 or more.

I imagine most people don't want to stop for a half hour charge in the morning or after work and on the road trips, unless they are having a meal while charging.

Not every day, but in practice fast charging goes up to 80% max (to protect the battery, after that it slows down automatically), only 60% for some car models. Drivers usually don’t let it drop below 20% (first and last 20% load slowest). Don’t tell the range phobia patients. Instead of half an hour, it’s 10-20 min. People stand still in traffic much longer than that. On road trips it’s really a non-issue, gotta eat, drink, stretch legs, take a piss, have a smoke or just enjoy the scenery. Apps make it easy to plan, get alerts with directions to cheapest or fastest.

And we have been 5-10 years away from groundbreaking battery tech for the last 20 years.

Some of them are in production now and there are factories going up all over North America and I would say there is many more times the R&D money going into batteries at all levels, from basic research to working the bugs out of volume production, than 5 years ago. There was recently a breakthrough in low temperature operation and charging for Li-on batteries for instance and Prieto battery I reposted above works well down to -30C, so do sodium-based batteries, important for a place like Canada. The entire industry is on fire and progress is very fast with huge rewards driving it, there is an entire supply chain being developed in North America and Europe from the mines on up along with lots of battery factories under construction.

In NA houses are wired for 220 volts with a 100-amp entrance being typical and it can supply over 20kw per hour for overnight EV charging, so in 10 hours most can charge an EV up to 200kWh. I'm assuming that a future battery like the Prieto mentioned above won't have limitations on charging.

I imagine there will be differences between NA with longer distances, heavier EVs and high home ownership rates than with Europe.

You don't say....

We don't exist in a steady state, and I have ample grounds to assume we are making progress in this area and have posted the evidence such as the Prieto battery above, of which there was little publicity.

A lot of times when they go commercial, they stop publishing academically. They have a protype, are building a pilot plant and the tech is claimed to be easily scalable. I would imagine some big fish will buy the company if it is a viable technology, or investors should not be hard to find. Compared to much-hyped solid state batteries like Quatumscape this looks very promising. Perhaps a patent search might be more fruitful?

How long do rooftop residential solar panels last?

Multiple factors affect the productive lifespan of a residential solar panel. In the first part of this series, we look at the solar panels themselves.

pv-magazine-usa.com

In its annual Module Score Card study, PVEL analyzed 36 operational solar projects in India, and found significant impacts from heat degradation. The average annual degradation of the projects landed at 1.47%, but arrays located in colder, mountainous regions degraded at nearly half that rate, at 0.7%.

Lotta people don’t figure in heat-cycle degradation. Out here in the Mojave you can lose 20+% in fifteen years. Add to that that panels typically lose 0.35% output for every degree C above reference 25 (panel temp, not air) and that on a decent summer day a panel
can hit 70°C easy, it only gets worse.

I imagine that would be one reason to cover canals with solar panels, aside from reducing evaporation by placing them on bodies of water, it would lower the operating temps and reduce such degradation. However, improvements in silicon solar panel robustness and longevity are being made too and the longevity of even perovskite solar cells has been improved considerably.

A recent case history shows 99% stability of cells after 1,000 hours using BondLynx treatment, emphasizing its boosted bond strength.

"I would imagine..."

I am sure you would.

"...this looks very promising."

Which part? They have been at it for over 14 years and I can not find any technical information on how well it works. None. If it is a slam dunk then why has none of the big boys came up with enough cash to produce a working battery to power a go cart?

They have a website, perhaps you should inquire there, there is contact information at the bottom of the page. https://prieto.com/

I'm not selling their stock, just posting articles about promising technology that appears to be on the cusp of commercialization.

They are building a pilot plant and seeking partners, so if they have anything serious to offer, they should have no problem finding investors.

Looks like power tools initially, EV batteries would require a big automotive player and are a leap, but they should be a target for some big player to buy, if they have what they promise.

Like I said, I'm not selling their stock and the announcement has been so recent along with the independent evaluation that the usual industry pundits have not weighed in, yet.

Just some local news so far, but it is sensible to go from smaller scale production for devices and power tools and then get a big partner for EV scale production. I posted it because it is a very promising technology that according to their claims, can be quickly and easily scaled up and is on the cusp of pilot production. Scaling up to EV size is where al lot of problems happen, but they seem confident they can do it.

Pay a subscription fee to an investor site and they might tell you! Or contact them, right now they are privately held, and the real money is in going public, unless a sugar daddy with lots of bucks comes along.

At this phase there are no earnings, just investors like Stanely tools and if what they say is true, there should be car companies taking a very close look at them. Dr Prieto does not look like a fraud to me, she looks like a scientist who is now cashing in on her work and has the credentials for credibility. I think this looks so promising that we should be hearing about bigger fish jumping in soon enough. I think a pilot plant for smaller size batteries for phones, computers and power tools is a sensible idea, but things are so hot in the EV sector that someone else might have other ideas.
