How large of a reservoir (depth/ volume of water)do you need to run a facility like this?

that’s amazing wow

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.
@craigwhite875 жыл бұрын
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.

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

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.

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 ?

No. But power used for pumping is much cheaper than power produced by falling water, thus profit.

@@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.

@@iareid8255 Grid load compensation is a good point too, but OP asked about the power used vs. power produced. Only the price difference makes it viable in the long run, since those reservoirs can provide even base load supply all day long, but eventually they require refilling unlike river powerplants. Hydro pumped storage is a net user of energy, because losses. I have always wondered why they don't build a filling pipe that diverts the water to go over the waterhead. Pumping against the entire basin wastes energy...

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.

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

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.
