A recent test shows that Quidnet’s technology can store energy in pressurized water underground for months at a time.

    Obviously, assuming you have that hill.
    Slightly harder to do in places like the Netherlands for example, where the tallest hill is 322 metres, and the second tallest that isn’t part of that same mountain range near the Belgium border is just 110.

    And in the US, Florida, Delaware, Louisiana, Mississippi, Indiana, and Illinois are actually flatter than the Netherlands - sure, the highest point in Indiana (Hoosier Hill) is 383 metres from the sea level, but the lowest point in the entire state is 98 metres above.

      In the cycling world it’s kinda funny how people try to make a low climbing century (100 mile route) as a first go, and where I am I have a glut of choices for centuries with well under 1,000 meters of climbing. I just cleared out a bunch of my routes, and still have two century routes with under 600m of climbing.

      True! I just wonder how much energy they’d realistically be able to store for a given amount of resources. Like, does this have the same issues as Lifted Weight Storage? Where the energy density just doesn’t really make sense once you get right down to it. I don’t know the relevant math to determine how much water and at what pressures might be required to scale this up to the 500MWh/1GWh range. It might be perfectly fine.
