the laura handle is after the news on there until the maryland come after me being tired cans team. thanks for joining in the living planet. dw podcast. how to make greener choices in your everyday lives. but honestly, try to do the working 32 hours a week to be better for the environment than 40. but of course we shouldn't be no need be the living scientists just had subscribe. whatever you listen to about cost, if you like history. but with the side of culture travel out of control the see this all right, just do it. and i guess that will affect the wow side to back into everyday life.

we're gonna dig up the, the, on the everyday things around us and where did they come from when, why did they have all the time? we can just search for the day increase the amount for of the addition to the this random assortment of stuff is all your needs to build an actual battery the let's see if it works. so now there's just a moment of truth. if i connect these cables like will one. now this is of course, super simple basic way it works. it's not that different from the batteries powering uh, phones, laptops, tooth brushes, and vacuum cleaners, cortes and even electric costs. all these things use a special type of battery code, lithium ion,

and they've gotten sold goods that we now building huge ones all over the world. and this may be the key to solving one of the biggest challenges of out time the on the 1st, let's back up a little 18. hundreds of themed telling them scientists of asenjoe volta invented the world's 1st veteran cold devil take pile. now our little coins back is a replica of bolts pile. we've got 5 cent court. instead of covering them, we've got these little watches that i played with think and in the middle we've got bits of paper that a sofa and vinegar. the reason this works of the chemical reactions that are happening here, very simply speaking, electronics so negatively charged particles, good freed up on losing cans and compound is ready to receive. once you connected with the cable of the electron stopped flowing from the link to the corporate law, you've got electricity have a chemical reactions and here it reversible. so once they are no more new electrons

to go over, the battery is spent just like it happens with your typical household battery that you throw away after using. for example, the ones in your results. the 1st rechargeable battery was invented an 18 and 59 by french visits as gospel once it is used to lead. and so for an assets, if you hooked it up to an outside source of electricity, the chemical reactions got reversed. battery got charged again throughout use different battery types for different purposes were invented. and then in the early 19 seventy's, the here of alice story, the lithium ion battery, 1st appeared on the scene. the person to come up with the idea for it was surprisingly assigned to us that the exxon mobil. thanks them, the oil giant was worried, the world was going to run out of oil. so it was scrambling to find alternatives. the battery he developed was rechargeable, and used lift the metal that's particularly reactive. so we could set free lots of energy. this original battery didn't make it big. video went through

a couple of hands though to improve digits for the region. sony. based on the concept them to a products, spots mass producing with the amount of batteries 1st using it in the camcorders with a new handicapped see or was it from the technology became a stand that and everything from laptops to power tools they can be charged at least a few 100 times and pack a lot of energy into a small space all of this month. let's see modern batteries. what perfect to power, personal electronics. and it wasn't long until another industry also recognized that potential. the automaker saw the opportunity and then they invest that a lot of money. this is evelyn a story who's an analyst and the energy storage team of research from blue book any yes. the automakers are basically the leaders on pioneers and making learning batteries cheaper and better. just the best rate is also relatively lights and don't lose much of that charge when they're not used under together. they're great

to power electric costs. so as more electric cars are sold, more lithium ion battery is, are produced, and that's made them a significantly cheaper since 2010, the price for lithium ion battery is, has dropped by 90 percent. just to put that into perspective, making one for a test level, why in 2010 would have cost $83000.00, making the comp prohibitively expensive. today, the battery only costs around $8000.00. and this dropping price makes them attractive to use for something even bigger than the cost storing renewable energy . and this console, one of the biggest problems the world is facing right now. we know that burning fossil fuels is heating up the planet. we also know that generating energy from the wind and the sun doesn't box the. so one of the key functionalities of energy storage and the grid is shifting the energy from the time where we have a lot of energy generated to time times other others later in the day where,

where we don't. and that's what batteries comes in. the middle of the day when there's lots of sunshine and your solar panels are working well, you charge the and once the sun is going down, they use the electricity stored in here to power the grid. and to do the same as your wind. right now the main way to store energy is through something called pumped hydro, to pump water up into a lake on the hill. and there's lots of critic tricity drawn down through the turbine. when there isn't. the problem is though, you can't built this any way where so you can put these pretty much any way. and so as best reprises keep falling back quickly, becoming the number one energy storage as technology 30 to man, but 3, the other ones that are competitive solution. this is me, kel, the all who works in the energy storage team of new when a private company that produces renewable energy. 2017. the dispatcher in the south of australia, which at the time was the biggest lithium ion battery in the wells. it was

a way to show to the, to the world that's human, but frequently a cost effective solution to, to supply and bends agreed. that's it. the group's case, this instant extended spell inspect them, the bachelor and control of a 100 megawatts equivalent of a smaller gas power plant. for up to one hour and 15 minutes, we've been boosting battery storage and mic breaking speed of a sense. in 2017, we build 1.8 gigawatts of storage batteries. 2023. we built 41.5 gigawatts. mess of jump in just a few years. they can catch me now is this one in california which can still 17 times more energy than the one in australia. even though it's located in the west, driving force behind the growth of good storage batteries, as china, instead of point the most and also producing the most defined batteries in the world. china had identified early the value and the use cases for which my

batteries, so they spent a long time, many, many years, developing the technology, scaling up manufacturing. and also it's an industry that have is received a lot of support from us from the government. so was that is we just keep pumping out lift in mind batteries and the energy system will pretty much change all by itself. well, unfortunately, not to make batteries. we need to buy and minerals and just like mining anything. this has environmental and social consequences need to keep those in check. one big step in the right direction is that there's no more cobalt and whatever. lithium ion battery is combining of which was also linked to child labor cobalt free best results for keeping them as fix just c. my a batteries can blow up to this is happening a lot less than used to risk manufacturers are working to make the cells. there's another challenge that's how to solve though, and that's to do with the storage duration. that's the time it takes

a battery to fully discharge at full power. if you think about your phone, that'd be the time you can play with it before it goes from fully charge to flats. for a new phone that would be around 10 hours of extra charge for the rick batteries at the pens. developers designed them based on those specific locations needs, ends in a way that can make money. for me. usually means the length of the storage duration somewhere up to 4 hours. and one big reason for that is because the sun and the big production of a solar energy loss about 4 hours. so you can charge for about 4 hours and then discharge for 4 hours. that means you have enough energy stored when the sun sets until people go to bed. things. so depending on where you live, it might be days or even weeks with very little sun and wind, which means we will also have to cover stretches longer than 4 hours. technically speaking, that's not a big problem. imagine this, that's where you can discharge 4 hours worth of energy. or you could just add

another one of the same size and you'd have 8 hours and you can just keep adding capacity like that. but with us do that is a question of money left because it keeps the tories as much a the better salesman better knows on the site. so it's almost like doubling the cost of the project. also operations wouldn't get to sell the 8 hours old at austin because for hours usually is enough to building bigger batteries just in case doesn't really make sense for them. there are other solutions at scale, but also to comp cheapo the most storage you built into them. what option is to store energy in gravity? another and pete looked at both of the separate videos, but it's questionable whether these can quickly become much cheap enough to move into the market because so much money and so much time has been devoted to losing my daughters to make them back cheap. it's hard for other technologies to compete.

you have it at this needs to shop them, still rich at to 81240 for the 24 hours. we're ready to move in the 3 week period. and we've used the most competitive solution, which isn't to say there won't be any space for other solutions, particularly for store energy for weeks and months. that's over the next few years . building lots of lots of good storage batteries already gets us pretty fast. to become carbon neutral, it says we need to triple renewable energy capacity. that switching fluency and to accommodate for all this flexible image. 17 times more storage batteries by then and we have today. this may seem like a daunting task. next to decades of innovation. you might have got to res, i've tried tested and ready to just need to keep building the if you heard of any big battery is getting billed. where you live, let us know and the comments, don't forget to hit subscribe for more videos like this one. the
