Energy storage in oxygen

[@martyschrader]

It is important to focus on the stationary storage market. Most people immediately think of cars when you mention new battery technology, but they are unaware of just how vital online, long term storage is for creating a sustainable, reliable grid. Keep up the reports on this good stuff, Mr. Borlace.

[@michaeldickins9238]

Energy is more then storage but of harvesting too, and self harvesting clean energy like solar wind, fusion,etc needs to be in each car,haouse aswell, and emerging tech could provide solution and maybe renieblae hydrogen too

[@samgragas8467]

Cars are the problem, sodium batteries are cheap but lack energy density. Lithium is scarce on planet Earth so it is not an option.

[@camronrubin8599]

It will be sweet when I can power my house and my electronics on my electric car . My Chevy bolt should have a 2000watt outlet inside of it . And it should be able to power my house if I use electricity conservatively for a few days at least. Solar water heaters are a cheap “battery”

I for one appreciate the fact that this channel exists as a reconnaissance of energy technology. Will all these technologies come to market at scale? No. But that's not the point. The point is to provide a view of the breadth of research and technologies in the energy sector. In that role this channel is excellent. I would recommend Mr. Borlace do a quick video on Technology Readiness Levels (TRL). This might help casual viewers to get a better understanding of the types of technology being discussed. My assessment is most of the technology is somewhere between TRL 3 and 5. Having that context might provide some viewers with a better sense of where the channel adds value.

[@samspencer7765]

More options chasing a finite amount of storage we need is excellent, a healthy competition of alternatives breathing down the neck of the established players improves the playing field for everyone 😊

[@falconerd343]

Is it finite? It certainly isn't static (hehe) or even linear growth. How about induced demand created by tech optimized for different limitations? Regardless, I agree, more options are better, helping to unseat incumbent, inflexible energy (inergy?) corporations.

[@ronkirk5099]

We will certainly need more of these alternate battery chemistries for stationary energy storage to take the pressure off scarce elements like Li which will be needed for mobile applications requiring high energy densities such as vehicles, aircraft, etc. The green energy revolution will need massive amounts of stationary storage capacity along with an improved grid.

[@mnomadvfx]

Large passenger aircraft are unlikely to ever be served sufficiently by any lithium based chemistry, even lithium/oxygen types. That being said - though it may sound ridiculous to imagine it, as long as you adequately separate the passengers from the battery these molten salt metal air batteries could be used for passenger airliners. The main problem there is maintaining optimum operating temperature with enough insulation.

[@JohnnieHougaardNielsen]

One very important comparison is how much energy is lost when storing/regenerating, compared to well-know techniques like pumped hydro, or storage in hot stones.

[@mnomadvfx]

Like all things with batteries it depends on the cell design and its chemistry. Electrolyte plays as much of a factor as the electrodes there too.

[@v.e.7236]

Every time I see a pic of one (or more) of those tri-bladed wind tubines, it really bugs me as to why the vertical axis turbine isn't more popular and more pervasive, considering their footprint, ease of production and maintenance, etc, along w/ the added benefit of being more bird friendly. Your segment about placing such turbines along the highways was an idea I had been percolating for some years and had actually proposed to my State and Federal energy departments and seems like such a no-brainer for increased energy independence.

[@teapot_]

Great presentation...thanks. it made me "just have a think" about battery storage that I've seen regarding tesla system storage in South Australia. I believe it was 100gw but not sure. It has enabled them to change over from coal. Got to be the way forward, even though some had doubts.

Another Sunday, another wonderful video from Just Have A Think. Thank you for all that you do, Dave. I've learned so much from this channel. And my goodness there are a lot of different battery designs! I'd no idea how many, until you listed your previous videos on the subject at the end of this one. They'd make a great playlist. The oxygen-ion battery isn't perfect, but I guess it's better than moving rail cars up a hill. The operating temperature of 200-400 C is a wrinkle, but designs like the liquid metal battery or molten salt require far more heat. It seems like this design is very middle of the road, with the very real advantages of being made from relatively common materials and being almost infinitely rechargeable. The long, long life of the battery would certainly be a plus for power stations. Just put some big boxes in there next to the transformers and keep them hot. No need to worry about ripping them out after 10 000 cycles or whatever, just let some fresh air into them and keep going.

[@krulerwest-oz7364]

I do still like the concept of the gravity batteries purely because of the simplicity, have recently seen a gravity battery/flywheel hybrid which was an interesting pairing.

[@idjles]

The problem with gravity is it has a super low energy density E=mgh, that’s why you need vast areas holding massive lakes. g=9.8 and h = a few hundred meters. So you need a massive mass to get the energy. The problem with flywheels is E =1/2 I w^2, where I is moment of inertia (= mr^2 for a disk) and w is spinning speed in radians/second. So here you need vast speeds ( and hence low friction) to store large amounts of energy. And this puts massive g forces on the flywheel so you have to build that so it doesn’t fly apart.

[@krulerwest-oz7364]

@@idjles I agree, why I found it interesting with the hybrid ideas, it was a deep mine shaft, large weight solar and wind got the weight to the top of the shaft and then over night it descended then via gearing would spin up flywheels , overall it performed better than the gravity battery by itself. Is it ideal, heck no, you cant go around sinking deep shafts all over the place, I just like how in that instance it works, but over all, nope.

Maybe it's just my own preference for longer videos, but I think your viewers have the attention-span to appreciate the extra length. All the development of these brilliant battery options is really inspiring. Batteries for EV's tend to get a lot of spotlight and funding, but clearly these stationary storage options are far more important for our actual clean energy future, so seeing new developments is always especially interesting. Honestly, I just wish our governments would fund more of these projects and help push their market adoption with supporting businesses. Quite a few governments are doing this to a certain extent, but many could really could do far more...I mean has anyone seen the US defence budget?

[@jeffreyroberts4637]

As you have said, the one thing tonight’s broadcast has shown is that there no shortage of alternatives to expensive lithium-ion batteries for energy storage, for when weather generated energy is in short supply, even if most are still lab based and requiring exacting chemical conditions, or extreme temperatures or pressures. There is one option that you do not appear to have covered which from what little I know would seem to be ideal for the 6 hours to 48 hours segment, the carbon dioxide battery (Energy Dome) basically, a closed loop system where a large quantity of carbon dioxide is repeatedly compressed with surplus energy, then allowed to expand to generate electricity, but best of all there is no Hughley complicated cryogenics system, and it is made from off the shelf engineering components, which should make the system affordable and easy to replicate, the only drawback I can see is the large size of the dome, but I am certain these could be accommodated at old coal fired power stations waiting to be decommissioned, the dome could fit where the coal was once stored, plus the transmission line would already be in place, so, we would be reusing an existing site, in most cases simplicity beats complexity. Of course, for long-term energy storage we would have to look at green chemical energy storage systems like green Hydrogen and green Ammonia. But for the moment a lack of energy storage is not the problem, it is the lack of renewable generation, which is being held back by huge delays in the planning process, and access to grid connections for wind and solar farms and tidal barriers

[@xpkareem]

For utility scale storage, size and weight is not as important as round trip efficiency, cost of storing a megawatt hour, and how long you can store it. Just look at Lake Meade. Very big and heavy, and also very useful.

[@Robert_McGarry_Poems]

I just had a thought... A Tesla valve, a large chamber, and a wind turbine that is optimized for high pressure. A wind tunnel engineered to let the wind in, but not let it out. Some kind of funnel to consolidate, and bring air into the entrance, which is the Tesla valve. This would lead into a large chamber, that slowly tapers down to the turbine inlet. Could break the input into many different smaller streams of air, which should reduce the pressure of each, giving the output a greater pressure.

[@dereksimpson7959]

[@JustHaveaThink]

Thanks for your support :-)

[@psylenced]

I wonder if you could combine with a thermal battery - using heat up to the required level and keeping the excess in thermal storage.

[@mnomadvfx]

I think you may be missing the point that in these extremely high temperature battery cells it is the ionic transport itself that causes the heating of the cell, and there fore as long as you initially heat it and keep the cells well insulated against thermal loss they will stay hot enough to maintain optimum temperature merely by doing exactly what they are designed for. ie charging during active sun or wind, and discharging during low to zero sun or wind. These ultra high capacity cells will become the backbone of solid state grid storage - though other sources may well end up filling out the rest merely due to cost.

[@joeblack4436]

Mobile vs Immobile? Gets to the heart of the matter. Anyway such batteries which one would think wouldn't need to move often, like Tesla megapacks, have a very important niche use case for making them mobile. Tesla even sells a product like that. The Supercharger truck. Useful to provide charging facilities to off grid operations. So we might as well add "semi-mobile".

[@NamekGregory]

Stationary energy storage is not needed. The energy on demand can always be generated using Gravity Energy Engine which can lift heavy solid blocks (concrete or dirt) on desired height and then powered the generator desired based on demand.

How do flow batteries square against Na Sulphur, liquid air, liquid metal, etc etc. And of course Li-ion tech is also advancing rapidly. The possible future tech needs to be compared with other future tech, not just current stuff, then we may be able to get an idea of which ones are likely to come out on top.

[@Richardincancale]

Lithium type batteries are satisfactory for short term frequency stability control where we’re not looking for huge storage capacity but need a good ability for power absorption or production. Possibly they can be feasible for diurnal cover for solar plants. The next big focus really needs to be on seasonal storage - taking solar power in the summer and keeping it for winter when solar production is low and demand is high. Wind is typically stronger in winter, but is still intermittent - a blocking high pressure area can all but close it down for weeks at a time mid-winter when it’s most needed.

[@ab-tf5fl]

Yes - the amount of energy storage required to save away solar energy during the summer to heat homes in the winter is truly gargantuan, but if it could somehow be achieved, it would a game changer.

[@tomkelly8827]

As someone who has lived with solar panels and batteries for the last 13 years, I still say lead acid can not be beat. Yes they need to be cared for but they are leaps and bounds cheaper than lithium for stationary storage and they do better in the cold than lithium does and when paired with capacitors, good charge/discharge cycles and watered when needed they are the best bang for your battery buck by far. For the grid, I still think dams are the best way to store and release energy. Not pumped hydro, just regular old existing dams.

[@mclovin1071]

With abundant enough stationary storage, large car batteries wouldn't be necessary. I really think current EVs are really overdoing it on the battery size, to the point that they are basically just spending battery to move battery around.

[@Psychx_]

What hurts the energy grid transition and the adoption of renewables as a whole, especially by keeping big players from investing, is the ROI. Solar currently yields 4-6%, while the petrol industry stated that they're only going to pursue such technologies when they're in the 8-12% profit range, well knowing that this will never happen. Stuff that is absolutely necessary to do, won't get implemented due to greed. Just being "cost-covering" would already be viable enough, when it pays for maintenance, and the salaries of the people involved, and if you calculate that in, also for a stepwise expansion. This is about our collective future and keeping the only habitat we've got livable, but seemingly, 4-6% just isn't worth it. Govts need to step in and either force the fossile fuel industry to hit certain transistion and diversification targets or fund the large-scale adoption of renewables with tax money. The govt-owned model used to be the go-to when it comes to establishing new infrastructure and is proven to work. Private investors won't do jack sh!t, and capitalism needs a replacement that enforces sustainability (economical, ecological and societal) as the #1 business priority, not profit maximization and utilizing exploitation. People could still get filthy rich that way, but would cause so much less collateral damage in comparison to now.

[@Teddystream.]

Two things concerned me in your video and raised alarm bell that's 200 C and oxygen, particularly when ionised. There is a reason why batteries are generally electrically the other way round because of the dangers involved with the active elements in the right side of the periodic table, especially when the temperatures are raised.

[@JonathanGarneau]

From my understanding, one of the main obstacles to mass adoption of intermittent energy sources is levellized cost of storage LCOS , factoring in round trip efficiency,cycle life, cost per MWh. Do you have any information how their optimistic projections compare wit other system's optimistic projections? As far as I know we're a least a factor of 10 away from a LCOS which would make intermittent sources cost competitive with conventionnal energy ?
