Ireland's first geothermal generator

    A planning application has been lodged with South Dublin County Council to construct Ireland's first geothermal electricity generation plant.

    The company behind the project, GT Energy, said its proposed facility at Newcastle could provide enough electricity to power 8,000 homes.

    Geothermal energy involves extracting hot water and steam from the earth's core by drilling boreholes deep underground - a technology widely used in places like Iceland.

    GT Energy started test drilling at the site in 2007 and investigative work resumed earlier this year.

    If the project secures planning and licences, drilling of the wells will begin early next year, with generation starting in 2012.

    GT Energy's Padraig Hanly estimates the development will cost around €30m and said the company is receiving technical assistance from ESB International.

    I read about this earlier today. I read up on it some time ago and thought it looked interesting but didn't know if it would work here. I like this idea. :)

    What, roughly, is 8,000 homes in Kwh?

    What, roughly, is 8,000 homes in Kwh?

    About 4 megawatts / 4,000 Kwh

    Above is a link I came across about other geothermal sites in Ireland. I was suprised when I read this as I didn't think we had any suitable geothermal sites in this country. It will be intersting to see if they are planning for any other geothermal generators. What is the typical ifespan of a geothermal plant?

    Newcastle is my home place. When I was visiting in May that company was taking sensor readings all over Newcastle (cables running along all the roads with probe heads stuck into the ground). It looks like they wanted final confirmation that it's a goer and it seems they got it. Best of luck to them!

    A COMPANY plans to provide power for 8,000 homes by tapping into boiling water hidden four kilometres below the Earth's surface.

    GT Energy has sought planning permission to build the country's first geothermal energy plant at Newcastle, Co Dublin, which it says will produce environmentally-friendly energy within two years.

    Widely used in other countries including Iceland, France and Germany, geothermal energy extracts hot water and steam from within the Earth's crust which is then used to drive turbines and produce electricity.

    It is considered a renewable energy source because the water is pumped back into the Earth after going through the power-generation cycle where it can be re-used.

    Energy

    Planning permission was sought for a €30m plant from South Dublin County Council yesterday, which if approved would result in a plant being built within two years, GT Energy managing director Padraig Hanly said.

    Some 200 construction jobs would be created, and up to 15 full-time positions when the plant is up and running.

    "The project is the first of its kind in Ireland," he said. "We want to harness energy from the Earth's core. We drill down 4km and harness heat energy before bringing that to the surface and supplying energy to the grid.

    "If all goes well we could go ahead next year. We believe there's potential for 10 of these across Dublin. This could provide 20pc of all the heat demand for the capital. Geothermal is an abundant resource. It's always on, unlike other renewables. It has minimal visual impact, and when built it will look like any other industrial unit. It's about nine metres high and sits on less than half an acre. There's such a minimum visual impact it could be built beside a school.

    "In Germany they're in planning for 150 plants. There's no reason why in years to come every town in Ireland couldn't have its own plant, supplying geothermal energy and heat. One of these plants could be built to cater for a hospital or a university."

    If approved, the company will also have to seek a licence to produce electricity from the Commission for Energy Regulation.

    Mr Hanly said the technology had been used since the late 19th Century in the US, and was safe.

    "It's simple technology," he said. "The pipes come to the surface for about 20 metres. The worst thing that can happen is the pipes leak. The pressures will be lower. The technology on the surface is all off the shelf."

    The €30m project would be funded by investors, and the plant should pay for itself in 15 years. Mr Hanly said electricity would be generated at a cheaper cost, while avoiding the need to use imported fossil fuels which contribute to climate change.

    Sounds good. Hope it works.


  • Closed Accounts Posts: 611 T Corolla


    Is such plants cost effective. If one plant can only supply 4MW of power to supply 8,000 homes how many would be needed to supply Dublin alone.

    we have geo thermal potential ha ha ?

    where in ireland do we have hot springs bubbling up to the surface, boiling mud pools anyone? apart from Lisdoonvarna in Clare.

    it sounds like patent nonsence

    this sounds as fanciful/ridiculous as putting a custom made ski resort in mulhuddart or that miscanthus lark.eu needs to examine this appa rent waste of f unding

    Maybe that's why they call it deep geothermal energy.

    I think I trust the opinion/knowledge of the investors who are about to put €30m of their money where their mouths are ahead of this sort of drivel.

    This technology is actually really low tech when you think about it. Germany makes good use of it and I can't say I've seen any bubbling mud around here! Did you bother reading the bit about them needing to drill down 4,000 metres to get the good stuff?

    And here I was about to post about how nice it was to see there was no begrudgery in this thread :(


  • Registered Users Posts: 5,278 ✭✭✭ dowlingm


    According to the SEAI maps a plant near Edenderry might work at the 2500m level, and there's a smaller zone just where the N16 crosses into NI. Lots of potential in NI.

    easy to call 'devil's advocacy`begrudgery. i sense tommyrot charlatanry quick & not without foundation, thanks.

    so how much/ or little do u kno of geology; apart from that tract from hi school geography text books that none of us care to rememeber


  • Registered Users Posts: 521 Voodoo_rasher


    so what visible evidence do we have of phenomena of a geo-thermal nature which is documented in ireland.

    i'm waiting.....

    nobody has enlightened on this yet


  • Registered Users Posts: 521 Voodoo_rasher


    200 temporary navvie jobs and 1..5..

    hooray. period


  • Registered Users Posts: 3,063 ✭✭✭ JohnC.


    What are your qualifications in this field if you are able to say with such certainty that there isn't something suitable deep underground?


  • Registered Users Posts: 521 Voodoo_rasher


    i am merely casting aspersions on the plausibility of this scheme. everyone here seems to blithely believe in it , without any first hand experience of this energy source. Who is the outside expertise; no mention of that in any article feeds that i can see. its not begrudgery.

    Can you use Google or is that technology also unviable?


  • Registered Users Posts: 521 Voodoo_rasher


    we're not germany, or could ever hope to be. i got the rancour straight away.

    no Irish placenames allude to hot subterranean water; with Ger you have placenames like Bad Wurttemberg, Baden Baden..

    no outside expertise involved in this here & and nobody has answered my question thus far. ("..so what visible evidence do we have of phenomena of a geo-thermal nature which is documented in ireland.

    nobody has enlightened on this yet further up yet"
    [/B][/B]
    funny how this geo-thermal water dont emerge out somewhere. it must escape out of irish terrain somewhere #yawn#

    keep divining folks

    Look, what do you care? It's not your 30 mil going down the hole. If it's a lame duck, none of us will lose a penny. If it produces the goods, then great! win win.


  • Registered Users Posts: 3,063 ✭✭✭ JohnC.


    So you still don't understand the meaning of the word "deep"? As in, I believe their tests have found, nearly 1.5km deep? They're not talking about surface geysers here. I don't think people naming places hundreds of years ago would be aware.


  • Registered Users Posts: 521 Voodoo_rasher


    oh i don't give a toss to be honest, a cara. pie in the sky. may give Tallaght Stadium some under-soil heating for winter airtricity games.. I'm surprised if they don't find themselves drilling in places that have since been built over by nama estates ha ha

    Don't like feeding trolls but as you asked ...
    Where else is there a hot spring?

    Why do you need visible evidence? They're not investing for the laugh, i'm sure. I presume there is a business case backed up by documented scientific evidence. Just because there are no obvious signs above ground, doesn't mean there aren't resources under the ground.

    visible evidence for justification thats all. as of a link from 1995 above, there is/was apparently very little subterranean thermal activity that we knew of existing here back then..

    its unlike Germany and France aforementioned; the evidence is more evident And tangible for them

    "Where else is there a hot spring?

    "

    to get the hopes up of the general popl. requires something substantive now. rumors of oil off Dalkey seemed tantalising, sadly.
    not investing for a laugh - no outside expertise or input tho'; seems they're going solo with this..
