Two Innovative Energy Storing Methods | Engineering The Future

[@Lordoftheflamesissketchy]

stored pumped hydro electriciy would store orders of magnitude more energy even if it was just a small dam or even large water tanks.

[@terranetti556]

Hydro is location specific gravity storage can be built anywhere

[@IvanPetrov-k2k]

​​@@terranetti556Two tunnels 10m of diameter 1km lenght. The first 10 m under the surface the second 500m. A tube and turbogenerator/pump between them. Water in. Approximate storage capacity 10 000 kwh (75 ooot water on 500 m) Not dependent of weather. Old mine tunnels could be used. Ideal for former coal mining areas.

@@terranetti556PHS is indeed location specific. But over 600'000 suitable locations have been identified worldwide. And even if only the 1% best projects were realized, they would total more energy storage capacity than the entire world needs!

there's already a bunch of youtube videos why this gravity energy concept is economically stupid.

[@tomholroyd7519]

Crane operators at the docks *have* solved the problem of swinging loads --- they are just really really good at it and time the swings so the load lands perfectly

[@steveyountz9184]

Seems waaaaay too complicated. Why not just build what looks like a group of elevator shafts together and cover it so it just looks like an industrial building and cover the south wall with pv cells? Fill each 'car' with 30-50 tons of dense sand, have one motor control two shafts. I'm clearly not an engineer but isn't the simplest solution, aka, Occam's Razor the best solution?

Interesting "battery" tech

Extremely wonderful episode through scientific prospectives and energy storage by gravity

[@xungnham1388]

This is just pumped hydro but with bricks instead of water.

[@markedis5902]

If they’re sinking bore holes, why not add in geothermal too.

[@DoesNotInhale]

Because it's not efficient enough just like solar or wind. Cope and seethe

[@GavinRemme]

Energy vault seems sooo much more complicated gravitricity. What advantage does multiple small blocks provide? It seems like so much extra complexity for very little gain.

[@DarkPesco]

Once it's constructed it lasts and will store energy over and over again without degradation much longer than our best batteries, today. They explained it in the beginning of the video with the grandfather clock that was hundreds of years old yet still functions perfectly. Those function off the same concept...gravity storing the energy and releasing it over time with the declining weights. It's much cheaper to maintain and repair than current lithium batteries.

Exactly! Simple, Sustainable, Cost Effective, Expandable ❤☝🏼💡

[@theowoytowich9959]

Is it realy cost effective and practical???

[@tomlakosh1833]

How about regenerative braking in elevators?

[@forgotten6411]

useless. The elevator doesnt require so much power, since it is counter balanced. Wherever it goes, it will have to use electricity.

[@JJMelendrez]

Waste of time, you gotta make the solar cells on a panel like a deep dish pizza thicker and deeper! 😂

[@arunbalaji6534]

Third. 😅

[@leonardogonzalez8433]

Second.😊

[@galaxyceiling4137]

In both cases I understand how electricity can be made by dropping a weight vertically downwards, but they didn’t say what the power source is for lifting the weight vertically upwards. A diesel generator? Sucking the same amount of electricity out of the grid as what you get back? Newton’s 2nd law is all very well; but Newton’s 3rd law also applies here.

[@GavinRemme]

Often renewables produce more power than necessary, especially in the middle of the day. Look up the “duck curve” of the grid. The system will use this extra energy during the day.

[@theowoytowich9959]

@@GavinRemme What do you do when the renewables supply very little electricity for days, weeks even months????

[@Rkcuddles]

Butttt…. Fossil fuels are only cheap because of government subsidies. Why are renewables having to match that?

[@Tennisbull-match-statistics]

Outdated

I admit I'm a cave man. Isn't this a lot of work creating what comes from a gallon of gas?!?

[@tomholroyd7519]

Recall your caveman origins, when there was no gasoline. Now imagine a world like that.

It's not the percentage of wild AC the public power grid is having to support from wind turbine and solar voltaic generated electricity that is substantially important, but its fuel savings, which is little to non. In the US the advertised fuel savings for supporting the wild AC from wind turbine and solar voltaic generated electricity by the electric utility grid is 1% each. That number is likely rounded up significantly. The wild AC from wind turbine and solar voltaic electrical generation should not be supported by the public power grid. The practical use for wind turbine and solar voltaic generated electricity is for maintaining electrical energy storage such as charging storage batteries or working with something similar such as hydropower. The electrical storage can supply the power grid or run pumped hydro for stockpiling water for hydropower at about 50% efficiency. Instant 100% backup of wild AC typically requires natural gas turbine generators running at high availability consuming a minimum 70% of the fuel of full output, but making little electricity, where in a few seconds they can be at 100% output to instantly backup the wind farm 100%. Making up the dips in wild AC will cause more than 70% of full output fuel consumption. It would use 66-2/3% of the natural gas of 100% back up of natural gas turbine generators to run a natural gas combined cycle plant at high efficiency output where it can make full use of a steam cycle adding 50% higher efficiency making all the electricity than to 100% instantly back up a wind generator farm for the same electrical output to behave as a scheduled power station. The cheapest incremental electricity is from hydropower and nuclear power. Second to those in the US would be a new ultra supercritical clean coal plant burning high BTU bituminous coal at a predicted crossover fueling cost with natural gas priced at $0.80 per million BTUs in 2022. US natural gas was priced at an offseason wholesale price in early summer 2024 of $2.50 per million BTUs, three times the fueling cost of the coal plant. This is the cheapest natural gas that could be expected without economic collapse. Winter peak natural gas wholesale prices can be several times higher. The US has some of the lowest cost natural gas in the world. UK wholesale natural gas was priced in US equivalence Oct. 2024 at $10.50 per million BTUs. It is not accurate to state residential electricity cost is greatly the cost of maintaining the power grid as sometimes said. In the US on average only 38% of the generated electricity reaches the residential electric power meter. 62% of the generated electricity on average is lost to grid resistance. A little less than $0.03 per kWh is average for US midwestern wholesale electricity scheduled 24 hours in advance. That costs $0.03/.38 = $0.078 at the residential meter. Our Cumberland, Indiana residential electricity in 2020 was priced at $0.10 per kWh. The cost verses sale price difference has to maintain the power grid and make some profit. Internally generated electricity should be significantly cheaper.
