Spirit of Ireland, Seawater Pumped Storage Proposal, A Breakthrough National Project

[oakfunkable]

the plan is coming together. Thus a system all begins with a simple stem

[alandmc11]

sounds like a good idea! 

[daydreamusic1]

great Idea ;)

Who produced this Diddley-Dei-del-Doo crap narrative? All it's short is John Wayne in a flat cap looking out to sea.

Anyway, where are the technical figures for this pipe-dream? Wind turbines are only 30% efficient. You'd need a lake about 32km squared and 10m deep to be of any real use.

@coggy5

A typical coal burning plant is 35% efficient, meaning 65% of the heat energy from the fuel goes to waste. With a wind turbine there is no fuel loss, no waste bi-products. So their 30% efficiency is actually quite good.

With energy saving revisions made to fuel station boilers, i.e. economisers and superchargers, the efficiency can go up to about 45%, meaning 55% of the fuel is wasted.

Not to mention the emissions.

@coggy5

Further to that Spirit of Ireland propose to build 3 reservoirs of 2km by 2km in size. This could deliver 100GWh per reservoir. Ireland uses around 70 GWh a day, depending on the season. Got my figures on the Spirit of Ireland homepage.

I'd be fascinated to learn where you got yours.

@CallingValleyForge. If you look at the FAQ page on the spirit of Ireland web page and scroll down to the question, What is the power rating for the plant, The answer is 3 x 1000MW or 3GW of power.

@coggy5

Ok, as mentioned in my other comment there, the plan is for several plants working together. Meaning that one reservoir could be refilling using wind energy whilst the other is generating. There will still be fossil plants for a long while yet, you could even refill the reservoirs on the nightsaver tariff if necessary, selling the electricity on next day at the daytime rate.

@CallingValleyForge- Now go to Eirgrids stats page where you'll find our peak evening demand was about 5GW last January

@CallingValleyForge - If you work out the kenitic energy that can be stored in a 2km x 2km x 100m head height tank-resevoir and run it through 3 x 1 GW turbines, you end up with less than 10 Hours of Power and the tank is dry. They'll need a hell of a lot of back-up resevoirs, especially in the summer.

@coggy5

Will definitely calculate the stored potential energy of such a reservoir, as its part of an area I'm researching. Before that, did you take into account that sea water is 2.5 times the density of fresh water? Meaning it has more PE. So if we take into account a system of dams working together, and that they could be refilled in cyclic order by wind energy, are we getting closer to a viable plan? Also, they plan to build a larger 4x4 reservoir to operate alongside the first 3.

@CallingValleyForge - Consider Turlough hill stores 2.3 million M3 of water. It only runs for 4 hours through a 0.3GW turbine before it runs out.

[CallingValleyForge]

@coggy5

Ok, Turlough hill is similar but different to the above proposal. It uses two reservoirs, underground tunnels, and the design is more complicated. It was built in the seventies, and ran into construction difficulties because of local seismic activity. It was state of the art then, but not so now.

we're a capitalist shithole where the working man and woman is never any better off

[MuthaLicka81]

now is your chance to change that.

[RbVDK]

Don't know why you made this comment on this video but what do you suggest? Socialism? Were big government makes all our decisions, because the working man and woman is too stupid to make their own choices. Right!

No i am a Distributist

[patbean]

Distribute all the money evenly, so no one have enough to do anything worth while?
