there's issues there, wave action could damage the inlet, also you then have the problem of tides, if you have surplus energy from renewables and the tide is out, you won't be able to pump to upper reservoir, same works the other way at high tide. the two reservoirs need to be self contained, controllable and unaffected from tidal processes.
The final advantage of a two reservoir system is that it can be created anywhere there are natural elevation changes. If one can mitigate evaporation this could even be done in very arid, high population density, areas (e.g. Southern California, the Middle East, Central Europe, Southeast Asia, India, Pakistan, etc.)
I am interested in how much more it will cost, If we compare it to a traditional hydropower station. If you tell me the price for 1 kW it will be really helpful.
@@sleeptyper there is a more fundemental reason for pumped storage, it is inefficient but it's purpose outweighs that, see my explanation to Mafarmega earlier.

I've heard efficiencies of 70-90%. This doesn't sound great, but if electricity is twice as expensive at night then this can make a lot of sense. The efficiencies are comparable to lithium-ion batteries. Yes - some power is lost. However, as batteries go, this is pretty good.
This is primarily a battery, not a power station. Think battery, not hydro-electric dam. The energy grid needs batteries for when the sun is not shining and the wind is not blowing. This battery can be built anywhere there is a lot of water (ocean) next to a high level reservoir (eg. the top of a mountain). Hydro-electric only works when the water is flowing down naturally already (eg. a waterfall). No natural water flow means no natural hydro-electric dam.

Great video. Thank you
I´m proud to know that there are companies looking for smart, clean and great solutions for the planet's imminent needs!
GE World Pride!
Nice ideas here.
yes
Surely you don't need to build two reservoirs. Just one near the sea. Then you also get the added bonus of using salt water which is denser.

salt water also has high corrosion, unless you invest more on the material to mitigate that, which would make it less cost efficient

that’s amazing wow
Awesome👍👍👍👍👍👍
How large of a reservoir (depth/ volume of water)do you need to run a facility like this?
this information is what we need to know before we decide to go buying hydro pump..
if there is any numbers that would be available for the energy Ah per cubic meter could be produced to compare it with normal batteries ?
the power of GE harnessing the earth's most abundant resources...
does the power produced while flowing = the power used for pumping back...???
No. But power used for pumping is much cheaper than power produced by falling water, thus profit.

Wouldn't it be smarter to use pumps that don't require electricity and make this a producer of power instead of a storage?

Nice, but put in some hard and usefull facts.
