Jonny 290 posted:flywheels do have some potential () but the problem is that to store any appreciable energy they need to be spinning really fast and the materials dont hold together. this is why the F1 kers flywheels are carbon fiber and poo poo, the thing's on the verge of centrifugally transforming into a metallic mist when its fully spun up we have flywheels as part of our DRUPS at the DC its pretty cool that you can pull more than a megawatt of power out of a 5 ton bit of concrete spinning in helium. there is another flywheel to start the generator with a giant clutch.

Shaggar posted:I would think pumping water up into a reservoir would work better than a bunch of trains. theres just not enough sites to make this feasible for storage at any reasonable capacity. like, not enough by a couple orders of magnitude. theres an interesting solution where you dig a big, deep hole, put a giant rock plug in it and pump water underneath and use the potential energy from that but i dont know how proven it is. i think someone did the math and weirdly enough giant loving lead acid batteries were still the #1 bet for massive load balancing batteries.

BangersInMyKnickers posted:the scale of energy waste on the grid due to day/night load cycles is absolutely absurd and if they were the sole provider for distributed energy storage they really would be that big but you have things like this: I had a similar idea involving catapults and very large dense rocks at one point. Shaggar posted:I would think pumping water up into a reservoir would work better than a bunch of trains. No poo poo. "Our weights are denser than water therefore better" completely ignores the fact that hydroelectric doesn't require a mechanic to monitor and maintain every hundred cubic feet of inert water individually. Also, I can't imagine that the numerous engines and electrified tracks required to match the energy potential of the "gigawatt dam" claimed in the video would cost less than the dam either initially or over time. edit - another thing: I thought local power storage and local power generation via battery packs and solar panels (or whatever) was considered beneficial, particularly to consumers who might like to have power during a rolling blackout. What's the rationale for shifting power storage to the side of a big mountain in Nevada? How does that alleviate grid overloads? Eugene V.

BangersInMyKnickers posted:long term maintenance is an absolutely pain in the rear end with pump storage and you need good topology for it. once cracks start forming in it, every gallon you lose cuts in to your efficiency and its difficult to find and repair them while in operation. they have scuba teams doing constant inspections on facilities and is dangerous work, because you can just get sucked in and killed at a leak. placement is much easier if you just need a grade and likely won't see the same rate of diminishing efficiency through the lifecycle, not to mention servicing costs will likely be lower. probably worth some trade off in efficiency due to increased friction https://www.youtube.com/watch?v=AEtbFm_CjE0
