Now a sodium ion battery relationship with potassium immersed in brackish water solution - ignited by a Plasma Arc reactor, would make an interesting energy solution to the world's "how do we get to other planets problem." Simply 'space hop' like a skimming stone across a pond. Replenishing Ions would be easy in space. A condenser to collect space ice would complete the equation. A substantial quartz crystal to harvest solar energy transfer through to the arc generator would ignite the fuse inside a vacuum chamber, which, in turn, can be released as propulsion as and when required. Mathematics is not as hard as you think.

The more investment into all types of electrical energy storage the better. Great work on parsing the data of these technologies and presentations that are understandable, informing, entertaining and balanced. Well done 👍

@@wolfgangpreier9160 That being the case, it's STILL nice to see something come out of the headlines and onto a store page, even if prices are relatively high and performance isn't that impressive yet. We've seen plenty of commercial products make major strides in performance and functionality as new versions come out, but too many of these things seem to just hang in development hell forever and never reach consumers at all.

A small quibble: The overall electrical generation system must get greener for any battery technology to provide appreciable benefit. Without that, we are just replacing carbon rich primary movers (ICE) with secondary storage for carbon rich primary generation(Coal, Oil, NG, Wood, Biomass), involving additional losses and increasing the carbon footprint for making, maintaining and recycling the secondary storage. In addition, we are concentrating the locations of emission, exacerbating the effects in certain locales.

Again an insightful presentation. The only Sodium battery technology that I was involved with was the old Molten Sodium Salt cells , as derived from Zebra batteries and touted by GE and an Italian company for railway traction use in the noughties. This looks much more promising.

With its lower energy density, would seem to be a good option for large scale grid energy storage where the amount of space they take up is presumably not as critical.

Nice to get an update on how the sodium cells are progressing.

I really want more research into sodium sulfur batteries. They would be be slightly more energy dense than comparable lithium phosphorus batteries, but a fraction of the cost like sodium phosphorus.

My guess is as production increases/budgets increases they might be able to improve things even more or cost goes down which could help it become more attractive as an option.

YES! Chunkier but cheaper sodium for grid packs, Lithium for EV's. At 22 million tons of lithium reserves and 8kg lithium per EV, that's TWICE the lithium we need.

If you're referring to the United States, ironically a significant reason why the size of vehicles increased so much was due to the supposedly environmentalist Corporate Average Fuel Economy regulations. These penalize auto makers based on how fuel (in)efficient their new vehicles are. However, CAFE defines different categories of vehicles, and sets different fuel economy expectations for each category. Rather than continue to make small vehicles and make those vehicles more fuel efficient, it's easier for auto makers to simply build vehicles at a larger size so that they're put in a more lenient weight class, thereby avoiding the penalty, without having to solve the harder engineering problems. They then run massive advertising campaigns to the consumers, convincing consumers that light trucks and SUV's are safer, more attractive, etc. Before the law was imposed, the industry in the US would make about 80% cars, 20% light trucks. Now it's like 35% cars, 65% light trucks, and we've ended up burning way more fuel and doing way more damage to the environment than if the law had simply not existed.

glad to see you revisiting emerging technologies, some of which are hailed to be society's silver bullets; one too many tech channels tend to make short form videos on these technologies, praise them to death and never talk about them again, once they fade away into obscurity

Thanks for another awesome & informative video topic. I'm looking forward to your new "where are they now" series. Electrification is certainly a critical component of climate restoration efforts, but it's also vitally important that they are enviro-friendly & socially responsible (climate is a symptom of a much wider ecological & biodiversity crises). Different batteries are best suited for different applications and, at the end of the series, it would be great if we could catergorise them into the areas where they are most suited, for example - thermal storage (for industries that use heat or for district heating applications etc) - batteries for the home or small business - batteries for a car, light industrial vehicle, heavy industrial vehicle, light aircraft etc - community battery storage (microgrids) or medium-sized businesses - grid-scale batteries or for large-scale businesses or heavy industries A company in the US (and I'm sure elsewhere too) uses second life EV batteries as grid-scale batteries. This type of "modular" design may also be useful (and cheaper) for micro grids. I am particularly interested in LMBs - Ambri. Their modular design may mean they are suitable for micro-grds and grid-scale batteries? Since the vast majority of people will live in cities by 2050, most climate solutions must come from cities. Energy generation & storage tech - in my opinion - should be located as close to consumers as possible.

I would like to see battery storage and "microgrid" tech incorporated into new building construction, especially large multi-unit buildings, both as a means of grid demand-smoothing (and storing any locally-produced energy such as solar panels) and to keep things up and running during interruptions in grid service. If I were a developer, I'd want to build something like that into any apartment/mixed-use building I'd be building. And since energy & power density aren't really an issue for this application, as wisely suggested in this here video, sodium-ion batteries, as well as liquid-flow batteries and a number of other storage technologies that have been & will continue to be covered here, would be well-suited for this, leaving the lithium for where its advantages are truly appreciated.

Having more options is always a good thing, even if it's just to provide alternatives when trying to cut a deal with a lithium cell manufacturer. You're not likely to get much of a discount, but having a little more leverage sure helps. I would love to see sodium-chemistry cells succeed, but we shall see what speed-bumps they'll run into down the road.

The biggest problem with Sodium ion (Na+) batteries is that the voltage is a little low over most of the voltage graph for a typical 12V replacement battery. Putting four Na cells in series creates a nominal 12V battery but the voltage is already well under 12V at 50% state of charge (SOC). The energy density isn't great when compared to LiFePO4 (Lithium-iron, or LFP) batteries, let alone NMC Li-ion batteries like those used in most EVs. The cost for Na+ is still higher than those chemistries for now. Presumably, that will drop as production is developed and refined, but bulk Na+ battery availability could free up the constraints on lithium, and might also just drop the prices of LFP and NMC batteries at the same time, keeping them cheaper, and still better, than Na batteries.

@daveduncan2748

@@PeterSedesse Nope. The main point is that the voltage vs. SOC curve is too steep in Na+ batteries. This is VERY bad for stationary batteries where the single largest load is usually the inverter. Inverters typically include a low voltage cutoff, and that would mean getting less than half of the theoretical SOC out of the battery, and the rest having a voltage too low to run the inverter. EVs, with their more complex voltage management systems are often better equipped for a voltage curve like that of Na+. But then you might as well go with LFP, which is lighter, cheaper, and already proven.

Thanks for the explanation @daveduncan2748, that may represent a challenge for the residential side of things, as the 12V batteries are almost in disuse, most solar for residential are made of 24V ones, anyway, we can use it in home use, but the fact that they can't sustain the voltage when the battery is 50% or less is a challenge. There must be ways to normalize the current, wish us luck! I going to research a bit more about the voltage variation and the stability of residential system using 12V batteries, just in case we, as a society, need to change to a more sustainable batteries for the closer future. And by the way do you know of any use of this technology in the residential sector? I know they are pretty new but, no harm in ask.

In spite of the opposition from the fossil fuel industry and their political cronies, the market will demand change.

Also agree. I started getting into battery technology for home backup use in 2015 and sealed lead acid (SLA) batteries were still the standard due to costs and availability. Then Li-ion prices dropped and became the standard and now is being replaced by LiFo battery technology as the preferred solution for home and EVs. The tech seems to change for the better every five years.

@@JeremiahTownsend- FYI, Lithium Iron Phosphate was originally denoted LiFePO4, but then shortened to LFP.

I feel like a lot of people are waiting for that to happen. Hence the downturn of EV sales. That, with people waiting for the NACS changeover, and all the early adopters already have their EVs. People want sodium ion and solid state technology to get into regular production. For vehicles, sodium ion would be best for smaller economy EVs and phevs. Also, it would be very ideal for battery storage for the home as a back up generator. Larger and high performance EVs will be other battery technology. Hopefully that all gets going in the next 2 years which would tie into the NACS changeover, and EV sales will then be huge by 2026.

I live for the day when we just suck up sea water, get fresh water for our needs, make hydrogen and store our power in sodium. The answer to many problems is as far as the nearest coast line. Thank you for an excellent presentation. Solar Bob

a safe battery for a boat that does not catch fire or explode is the game changer a lot have been waiting for including me, I would love to dump that noisy generator

i love your channel and watch the new vids when i see them. I want you to say this again and for you to know it isn't meant as an insult, your voice is perfect for bedtime, it always helps me get sleepy and ready to pass out. Make a audio recording of your voice telling stories for kids or something and parents will play it for their kids to fall asleep to, just trust me, it will work. Or you could just read the dictionary...

High quality content ❤

sodium ion batteries are rolling out way earlier than i thought. About 4 years early. 90% recyclable. No need for nickel or cobolt. Much cheaper and easier access to sodium over lithium. Then charge cycles and battery density ramping up. Li Ion factories easy to convert to Na ION. Reliance in India planning multiple GigaFactories. CATL in china going full speed ahead. Natron is USA have interesting heavy duty batteries for grid storage, or shipping. Low power density. But tens of thousands of duty cycles. Lastly zero chance of thermal runaway. And batteries can be zeroed. So no fire risk from short-circuits if transported.
