Batteries are cool too.

Agree I want him to read bed time stories to me.

I get the idea, but it does require actual acting talent and practice, not just the raw voice. That's why we hire professionals.

@@theunknownunknowns5168 not these ones! You know, because 250 C is pretty hot. Oh, how I laughed at my hilarious jape. :D

Actually China is leading the world, LONGi have achieved 33.9 efficiency,

@@-PORK-CHOP- Depends how you define 'leading'. Oxford PV are closest to putting them onto the market based on reports I've read.

If your main market is the EU, it probably makes sense to produce in the EU compared to the UK.

That would be "Bonne chance" ... Luck is a Lady.... as an Anglo who is always spotted for this kind of "mis-gendering" ... you have my deepest sympathy ;-)

​@@raphaelg.7574its more to do with current expertise and infrastructure it's like making cars in Scotland a stupid idea with lazy work force

Yes! Welcome to the club. Grab a glass of grapefruit, rocking chairs are available.

Indeed let's add another element to the conversation ... hydrogen. Judging by the number of car makers developing hydrogen fueled vehicles batteries are already on the way to their place in history. We don't hear that much in the way of these giga factories bruited about in the popular press either. Perhaps a modicum of economic sanity has arrived at Westminster and the senior ranks of industry? For them as trouble to keep up with hydrogen technology then hydrogen is fast becoming the poster element of governments worldwide. I would repeat that the very recent events of three London battery buses bursting into flames inside two weeks will be giving pause for thought among manufacturers, until a cause is found.

Ah...salt in battery

Great video

did you look at 2nd-hand lead-acid traction batteries?

lorry batteries £100/KWh is fairly easy to find, £50 if you strike lucky.

You are being ripped off. The cost of lithium ion is now down to less than $100 per kwh. I suggest you shop around.

Not lead acid though. They won't last very lng with deep cycling.@@alanhat5252

that's getting into sales details, too much for a talk like this. Check their website while watching.

They showed you what appears to be a ±1m³ unit(?) . They stressed the preferred application as commercial scale long term storage. . Maybe a district sized solution of 1 container per "x" homes would be sensible. . Rooftop solar on the homes. . Sending excess energy directly to the "local battery" (solves the "PV land area" issue?) . Those homes receiving the stored energy back when "the sun don't shine". . Unused capacity sold to the grid. ..... No battery infrastructure required in individual homes, but those homes receive similar benefit to an individual battery without the cost......?

Large players are desperate to maintain "grid stability" and revenue streams. We the people will tend to remain net consumers. Some distributed storage can reduce need to upgrade grids and local ringmains, but the market wishes to keep control of grid level firming.

Probably an ideal location for such a system?

We are going to use massive amounts of storage. My heat pump can consume 50kwh on a very cold day in winter when there may be no wind and never much sunshine. Multiply that by 20 million or so properties and we get to as much as 1 terawatt hour per day just for heating. That might have to be supplied for many days on end so the storage requirements are truly colossal.

​@@rogerphelps9939so we need to get on with all the tidal energy projects that have been queued up for years waiting for Gov't approval

@@rogerphelps9939what energy would you previously have used?

​@@rogerphelps9939Given heat pumps deliver heat that's multiples of the energy consumed, your house must take 100-200 kWh to stay warm. You seriously need to invest in insulation, or are you living in a tent?

@rogerphelps9939 . So I assume you have an air sourced heat pump? . Surely if you're in an area where the pump *consumes* "up to 50kWh on a very cold day", a ground sourced pump may have been better due to the consistent temperature? . Otherwise it seems your logic is "off"? . ("20 million properties" indicates "homes in the UK?)

sounds expensive. is that the cell cost or already installed system price?

@stefanweilhartner4415 I assume that would be the system cost. If you compare it to a 13.5kwh tesla powerwall that costs about $11,500 installed. That works out at $852/kwh. But Ambri's system is grid scale and comes in the form of a shipping container sized unit. What a grid size, Tesla unit costs, I have no idea.

Zat so

Tata is written on the big battery in the corner, no explanation given.

That would be an excellent idea, which is probably why it's not gonna happen. Don't forget that, if by chance, the installation happens to be near the coastline, the moving mass of the water could fill the batteries. This is just a fantasy, it's much more likely that each individual aspect will be done by indépendant companies, who don't care about the globale aspect of what they are doing.

Can I chip in with a comment? That’s a bit fishy.

Love the rhythmic use of the word 'as'

part of their point

dragging it out of a hole in the ground is even cheaper & that's what they're doing

Why would they use waste when it's cheaper to extract it and make more waste? It's not like we haven't got anywhere to chuck it all. We haven't even half filled up the oceans with crap, and we can burn lots of it, which doesn't even go to the oceans. If that's not possible, just dig a hole and put it in there. Using waste would only be a good idea if we didn't have anywhere to chuck it.

Rooftop solar on every home. Out the battery in a container at the end of the road. . Use ONE connection to the grid rather than however many homes are connected (that's been a criticism of home storage). . Cheaper for the home owners. More space efficient. . Easy, efficient connection to the grid. . Easy power management.

@rogerstarkey5390 that is a good concept. 👍 For Australia with 20 million buildings and vehicles, which is just a coincidence, then a simple automatic selfplug-in EV means that there is a good amount of electricity storage just with that basic arrangement. And rooftop PV. The inverters can be standardised. The vehicles are connected to the grid 23 hours every day and trickle discharge or charging. This seems to be the simplest and cheapest way to go. No grid expansion costs. Battery technologies evolving rapidly. PV panels technologies evolving rapidly. Auto manufacturers know that they can also be an energy business. Uncertainty in government and vested interests are confusing forward planning. Nuclear electricity does not work well with renewables for many countries or the world. The world does not have enough time or resources or money for the grid electricity solution. Vehicles can disconnect, drive, and connect to the grid or building or home or shopping centres or ... The automatic connection is the cheapest and simplest thing. Home robotic vacuum cleaner and robotic lawnmower do this daily. Millions do it. Selfparking EVs should be able to do a simple 'nudge connection or plug in' and unplug as the driver leaves the parking bay. For Australia, that would mean 4x to 6x electricity in storage daily and double the fossil fueled electricity generation daily. The storage is free with the EV vehicle, Hahaha Hahaha. Simple numbers and minimum work. Private individual minimum investment with double value. Road loads from heavier vehicles will add to road maintenance costs, but it may only be until lighter batteries evolve. We need more people thinking about the future, the best 'road map', and not expensive investment in dead-end concepts.

@@stephenbrickwood1602and when will global car manufacturers conform to an Australian standard ? When will EV uptake in Australia actually reach a point where the batteries in the cars actually make a dent in storage ? When will 100% of homes have solar on the roof ? To achieve what you set out requires standards and coordination will meet resistance and will not be a silver bullet. For instance to really meet climate targets less people should own cars, less people should live in single family dwellings, so there goes your storage and source of power. The NSW government is pushing metros and people walking to them instead of commuting by cars for instance. The low density lifestyle of Australians that you’re solution depends on is itself a burden on the climate

​@francesconicoletti2547 4 million homes have rooftop PV, now. 200,000 EVs now, Things are changing and will change faster as all technologies improve.

​@@francesconicoletti2547 It is predicted that the Chinese and Russian population will crash and reduce CO2 emissions, but let's not wish for that.

It's pretty bad and that can't change because lithium is a better carrier. However, it's fine for storage, which we need tons of.

​@@cg9867,000 cycles was mentioned, which beats lithium's 5,000 baseline.

​@@alanhat5252 Sorry, but it won't be able to compete. I am not going to explain to you the logic of the periodic table.

check their tech info. But there is significant industrial uses for liquid or gaseous chlorine.

it ends up in the battery from what they're saying

@@alanhat5252 , yes that was interesting, I was fearing the whole Sodium battery industry would be the new CFC-like producer. Not all revolutions are progress. Let's see what the Chinese manage to bring forward with Na Ion (Hope the chlorine is managed well).

SHURE are the go-to microphones for podcasts, if the team has the budget - which they do. Good audio quality as, even though we're watching on KZfaq, the audio distribution is big too - Spotify, etc.

totally unnecessary, hey?@@mrjonnyjones

​@@mrjonnyjones Yes totally OTT. You'd get perfectly adequate performance with Yoda or Pace (or any number of different badged names) electrets at around £15 to £20 a go. Used them for years doing "radio plays" in our theatre studio. Chinese must knock them out by the million, stick on a "name" and flog them off cheap. Electrets certainly adequate for speech without going mad on condensers and needing 48V phantom power out of the desk. Repeat, it's only speech in a quiet environment.
