What weighs as much as a Toyota Corolla, spins at thousands of rotations per minute, and, a Utah entrepreneur hopes, might one day live in your backyard and store power to run your home? It’s called flywheel energy storage.
Learn more about how this man is creating his own power.

These would be useful in supply inertia to the grid. As we take out the rotating mass of coal and gas turbines and add renewables the grid loses inertia which really has a very important role in stabilising the grid against loss of power from a generator dropping off and before others can pick up the load.

Make a massive Steel flywheel the width of an Olympic swimming pool and the height of 5 story building and spin that at 100,000 RPM then pop the clutch and drive a massive generator

They have that in the UK for testing nuclear fusion. They can discharge 400 megawatts in 20 seconds.

@kaptainkraken 8 месяцев назад

the larger you make it the less speed you need to get loads of power.

This might be a bit too expensive, and possibly unsafe, also, physically impossible, like building a heavy cargo airplane with a wingspan of 2000 meters.

@joey3291 8 месяцев назад

Imagine a fully-charged, heavy spinning wheel flying out of its container... it would destroy everything on its way, which batteries can not do...

would it be safer if it was built underground?

@Qeswara 5 месяцев назад

The same can be said about toxic batteries that are at risk of exploding and failing.

@@sony5244 they really don't. Especially if you're trying to reduce your carbon footprint. Production of lithium batteries is extremely destructive to the environment at every level, from beginning to end.

Efficiency is usually around 70 % for flywheels or Pumped Hydro. Not as good as the 90% in batteries. He already has hydropower, he could just build a couple of small dams and add a cheap pump and some valves and control system, and he would have Pumped Hydro storage at low cost.

@justajo2 Год назад

He could, but in his area isn't there the problem of everything freezing in winter? In this short piece we don't get the entire history of why he chose the technology over hydro. Besides, he's done this for everyone and not just for those who have property with water running through it.

@awdrifter3394 Год назад

He could, but pumped hydro isn't getting those "advanced energy storage" government subsidies. Most of these companies just exist to get government subsidies, when those run out, they go out of business.

@JorgBrown Год назад

Flywheels don't wear out after 5-10 years, like Li-Ion batteries do. Yeah, 90% is better than 70%... but not having to replace a $50,000 system is important too.

@dingdingdingdiiiiing 5 месяцев назад

@@JorgBrown to be more precise, only some components wear out, like ball bearings, but they are relatively easily serviceable and cheap and I could imagine them working without a hitch for 15 years.

@bob15479 4 месяца назад

it's better than that, just look at the wikipediai page.

@dingdingdingdiiiiing 5 месяцев назад

Hydro energy storage still beats it and takes it's lunch money. If there is a large height differential, you don't even need a large body of water, but if you do have a large body of water, like the Jinping-I, it generates 3.5TW, as much as the largest nuclear power plant in the US. By the way, the solar electricity production of the whole World is at about 2.3TW.

@alechorn1109 3 месяца назад

What about Earth rotation? Wheel would need to be forced to do a 360 degree longitudinal rotation every 24 hours. This would wreck avock on those magnetic bearings.

@paradiselost9946 Год назад

every powerstation already has "FES". the turbine, and the rotor. hundreds, if not thousands of tonnes spinning around and around and around... they store TEMPORARY power to maintain steady RPM. to absorb variations in delivered power and load. wait until you delve into critical shaft speeds, resonances, and the issue of staying below, or accelerating fast enough to get past these zones without disintegrating... a smart one would have simply added a few tonne of flywheel to the "hydropower" he apparently has somewhere. why add so many extra steps, producing electricity just to spin a wheel to then produce electricity? that will only ever return 1/4 of the power it took to get it up to speed. people fall for this BS because theyre ignorant. stories like this only strengthen the ignorance.

@thomasgade226 Год назад

You're mostly right about the cost. But adding weight only adds a few seconds of storage. He stores 10 hours (10 kWh energy, 1 kW power = 10 hours) . Efficiency is usually around 70 % for flywheels. Not as good as the 90% in batteries, but better than 40% in compressed air. His competitors already have serial production.

@pin65371 Год назад

@@thomasgade226 flywheels can get up to 90% but that is with magnetic bearings and with the flywheels being in a vacuum chamber. This only really makes sense once you go big since the costs of increasing in size doesnt make a massive difference. These would actually make sense at wind farms. They can keep the power output consistent by dealing with peaks and valleys with output. Some other forms of storage other than batteries can sometimes take a little bit to really ramp up. The flywheel could also fill in the gaps between when power is needed and when its available.

@alechorn1109 3 месяца назад

Traditional flywheels are made of carbon fiber and shaped like a flying saucer, thick in center to withstand tremendous centrifugal forces with a thin edges to permit high RPM’s. Keep in mind that almost all of the energy is stored in the last fraction of inch of edge.

@deathbyslime6725 7 дней назад

more than rpm, you need inertia, given by the outer ring you mention. big heavy outer rim gives more inertia than the saucer, hence, more practical for storing energy.

Since 15 years, I have been dealing with angular energy electricity generation systems (R&D). My positive designs related to angular energy continue. In this regard, my own financial means are insufficient, I had meetings with many businessmen, they accepted the financing of the project, but they gave up when it came to signing a protocol, that is, when it came to formalisation. If there is an entrepreneur who will walk with me on this path, who is idealistic, has financial means and wants to make an official protocol, I would like to meet.
