Guy Tests The Water Pressure Of A Hydroelectric Dam | Guy Martin

In his latest series for Channel 4, Guy investigates the past, present and future of British power stations to work out how the country makes its most valuable commodity of all - electricity. In this clip, Guy opens up a dam waiting to explode with water and finds how this water flow can be affected by energy. To watch the full series, head over to All4: www.channel4.com/programmes/g...

There are 2 more in the pipeline, as it were. 1 on Loch Ness called Red John, and 1 on Loch Lochy called Coire Glas. Foyers, also on Loch Ness, has been operating since the 1960s. There are a few smaller schemes in operation.

Think about this. When you include accelerated mass energy in efficiency computations, the efficiency of a hydro turbine never exceeds 16%. What could we do different to improve that efficiency closer to 100%? No 100% is not possible, but why not eliminate accelerated mass and get closer to 100%. Like 90%. If we do not think about it we will never do it.

At last a solution far better than a battery. The UK should be doing this on scale. And there are more places than you might think where this is possible.

[@MrBen527]

This water battery method has been well known for awhile now. It still takes a lot of money, equipment, and water to make it worthwhile.

[@theoutsider6191]

@@MrBen527 I hear ya bud, nothing is free. However once you've got this going and set up it would be among the cleanest forms of energy storage. And the idea is basically the same as hydro power, which is already fairly popular in Scottage 🙂 So yeah, they could do more of this for sure. I regularly drive past Tintwistle in Yorks region, and there are about 3 large dams in a row, imagine if the pump facility was at the bottom to the top, with 3 hydro plants running down the chain every time... could easily power most of Manchester. And this would be the best way to set it up, multiple plants consecutively down valley. Maximise the gains.

“Generating electricity for 90,000 ohms”

[@unsaltedskies]

Couldn't resist that pun?

[@Bossmodegoat]

“Whatter”

[@flesz_]

Instead you can dig holes, drop heavy rock down the shaft when you need electricity and lift it up when in excess

[@zounds010]

The problem is that that's difficult to scale. Dinorwig power station moves 390 tons of water per _second_ to generate 1.8 GW, or 1.4 million tons per hour. The largest winches have a capacity on the order of 1000 tons, so you'd need 1400 winches to generate as much power as Dinorwig's 6 turbines.

[@randypratt2887]

What if you used the water being released to pump water back into the dam using no electricity 🤔

[@gyanrai7583]

i work in 1200 MW HEP

[@serdarcam99]

its a poor design tho you pump water from river but extracting its energy right on the dam turbines could installed near the river so water could gain more energy while moving downhill

[@2wiseib]

440MW - sorry but a drop in the ocean and what about the pumping losses. At least it can provide Mvars as needed at anytime

[@hardrays]

we are in an era of massive parallelism marked by distributed smaller systems. these pumped storage "water batteries" dont benefit so much from scale as primary generation plants do. but you need a hoo.

[@zounds010]

Efficiency of pumped hydro is around 80%. Pumped hydro was unique in that it offers very rapid changes in output. These days, batteries offer that too, but nobody's using batteries at the scale of pumped hydro yet: this power station can supply 7 GWh.

#99 MESIN AIR NYA BAGUS BANG 😂🇮🇩

[@wonton8983]

Years ago when I was an electrical apprentice, 1980's, we were told of a proposed American scheme, where they would use excess power to compress air to a few psi above ambient and store it by pressurising a huge underground cavern, what came of it I have no idea.

[@margarita8442]

[@paulbedichek5177]

It's working.

[@zarthemad8386]

caverns are already used the Nat Gas, propane, or ethane storage.

[@zounds010]

The problem with compressed air storage is that when you compress air, it heats up. The heat then leaks out through the rock, and the amount of energy you can recover is relatively low. It's less efficient than pumped hydro.

Fun fact : Nuclear is "greener" because dams release a lot of methane from organic decomposition caused by repeated flooding

[@gregorymalchuk272]

Hydroelectricity is fine. They last hundreds of years, so any methane from preexisting vegetation gets amortized over centuries of electricity production. The greens hate both nuclear and hydroelectricity. Because they are the two forms of carbon free energy that actually make economic sense and don't require demolishing industrial civilization and rebuilding on a basis of artificial scarcity and control.

[@kimw200blaze4]

Not necessarily. In colder places where large scale Hydro-Electric schemes exist, like Tasmania in Australia, NZ and Canada they don't emit as many methane emissions as you presume because they are in colder climates. Hydro -Electric is vastly superior to nuclear, as it relies completely on an pure renewable source of power ie water. Nuclear power by contrast relies on an non-renewable source of power ie uranium. Unfortunately however for an lot of jurisdictions they don't have the necessary water catchment areas to support the uptake of large scale Hydro-Electric infrastructure options.
