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

www.spiritofireland.org

We have the energy, imagination and skills to solve our problems and create a bright future for our children and future generations.

A breakthrough National Project will create: * Tens of thousands of jobs * Achieve energy independence in five years * Save €30 billion importing fossil fuels * Create potential to add €50bn to our Economy * Slash carbon dioxide emissions

We are all obliged to use our wonderful natural gifts, resources and talents to create a new future for our nation. At the same time we can help secure European energy supplies.

Creativity and endurance have been synonymous with Irish people since ancient times. Ireland has no fossil fuel energy of significance. Our limited gas reserves will not last long.

Let us begin

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

[alandmc11]

sounds like a good idea!

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.

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.

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.

[coggy5]

@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 - 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.

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

@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.

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.
