    Pipelines on the sea floor are great for energy security, just look at Nordstream 1&2. Interconnectors for electrons are even better, as you need even less explosives for those.

    Looking at this another way - any future energy project investors will judge their return on investment and project viability on this one. We've made it so hard for them to build a much needed LNG terminal in Ireland that when they weight up whether to build a wind farm in Ireland or anywhere but Ireland they'll probably build it elsewhere. All this is doing is hurting investment in renewables.

    Of course if ER would stop preventing the search for and exploitation of NG

    Inishkea got approved a few days ago

    Barryroe is a different story as there serious questions about the viability of Providence to be answered IMHO.

    Maybe they'll be able to show they have enough liquidity, expertise and ability to progress that venture, maybe they won't.

    If there are so many FSRU’s in Western Europe, why do we need one? We can borrow one from elsewhere if we get really stuck.

    What energy security would an FSRU of our own give us?

    An FSRU doesn’t guarantee supply in a squeeze.

    Anyone who is going to the trouble to blow up the gas interconnectors (hard) is also going to torpedo the FSRU (easy).



  • Registered Users Posts: 19,865 ✭✭✭✭cnocbui


    Why does Barryroe have to prove their finances? It wouldn't be a specious requirement invented by ER to justify his deliberate tail dragging, would it?

    Typically, companies raise funds after securing a licence, as was the case when Lansdowne raised GBP6.1 million in July 2011 for its share of drilling in the Barryroe appraisal well.

    Back up the we can borrow one bit. A sweeping statement at odds with reality. All LNG resources exist because someone needs them and paid for them, they wont be leasing or lending them to anyone in the forseable future.

    If you think there is a vulnerability issue, all the more reason to build one on land. If you have some nonsense come-back about torpedoing LNG tankers, I'd say WW3 would be of more immediate concern.

    Anyway, the mention of FSRU's was just to highlight the nonsense that LNG is too expensive to be used, when the European hyperactivity in relation to providing new LNG infrastructure clearly makes a nonsense of that pathetic argument .

    Its a requirement for the issuing of a licence, that they have to show they have the funding, solvency, ability, expertise, demand etc.

    Note, the same requirements exist for all offshore developments, gas, wind, oil, they all have to meet the same requirements

    Some interesting numbers from article below:

    On the Dutch TTF platform, which is seen as a European pricing benchmark, gas for day-ahead delivery was trading below 30 euros per Megawatt hour at the start of this week. But gas for delivery in February was priced at more than 130 Euros/MWh. That reflects market expectations that supplies will be tighter in the middle of winter than they are now.

    To compare with US prices quoted in million BTU, you divide by 3.4 I believe. The € and $ are almost at parity so that part is easy.

    The above then are approx $8.80 per million BTU now, increasing to $38.23 for delivery in Feb reflecting the tighter supply and higher demand in the middle of Winter.

    The equivalent US prices are $6.90 for now and much the same price for delivery next Feb. So, we'll be paying $38.23 next Feb and the US will sell it for $6.90. That's a big gap and presumably why the energy review said that more LNG infrastructure in Europe will bring gas prices down overall.

    Interesting spot prices in the US. Considerable variation which shows how different gas is from electricity in terms of how it is traded, but so much cheaper than Europe everywhere.

    Never said it was too expensive to be used, I said it being expensive made it a poor choice. Immediate actions to get over an emergency do not indicate long term plans.

    As we can see from the likes of BASF etc, high energy costs are going to have massive impacts on industry, especially the chemical and large scale industrial entities.

    The smartest option is to reduce the consumption of and/or get gas out of the mix asap which the likes of Germany seem to be going for with their stampede towards green hydrogen.

    No matter what way you cut it, gas looks like its going to be pushed out of the European energy mix a lot faster than planned due to both Putin and the adverse economics of using LNG. There will always be some amount of it, but the high costs of LNG will increase the pace of its decline

    The quote I posted says otherwise. Perhaps you could quote the legislation.

    If the Irish interconnector went out of action then continental demand would fall. By the end of 2027 (the earliest an LNG terminal could be established in Ireland) there will be plenty FSRUs in ireland.

    a gasification terminal does not guarantee supply. It’s only a small part of the supply chain

    a surplus of LNG gas will drive down EU gas prices but that has nothing to do with whether we establish a permanent LNG terminal in Ireland. An LNG terminal operator would sell their LNG into the Irish market at a price just marginally below the EU price.

    What risk would a permanent LNG terminal protect us against?

    Once we start cutting down emissions we will need less gas. Target is to reduce by 80% by 2030. That's a lot less gas.

    Storage in old gas fields is cheap and most of the infrastructure is already in place. And it could store hydrogen gas later on.

    Liquid hydrogen is in a different league of difficulty and energy loss to LNG. The energy released when ortho-hydrogen converts to para-hydrogen is more than it takes to convert liquid hydrogen back into a gas. In other words you have to use a catalyst to release all the energy before you store the gas. Wasted energy.

    These proposals are all being funded by the private sector. It's their risk then if their investment turns out to be wasted because we end up cutting gas consumption by 80%. In the case of the proposals involving FSRUs that's not even a risk as when it's no longer needed the ship will just go somewhere else. I believe Eamon Ryan said the Kinsale proposal won't happen because the pipeline to connect the FSRU is "old".

    Meanwhile I see the UK is doing a big deal with the US for fracked LNG. We're going to be importing a lot more fracked gas whether we like it or not.

    "These proposals are all being funded by the private sector. It's their risk then if their investment turns out to be wasted because we end up cutting gas consumption by 80%."

    All the private sector LNG proposals are desperately looking for government funding, subsidies and price/purchase guarantees. That is why non of them have just gone ahead with any or these projects, despite having planning permission, because they simply don't economically work without heavy state support.

    If demand drops in future, the FSRU won't be going anywhere as it likely means demand for NG has dropped all over the world due to the advancement of renewables. This is why gas produces and suppliers are desperate to lock governments into long term contracts, they know where the market is heading.

    I'd be interested to see any specific details of the above. Shannon LNG had planning permission, but didn't go ahead due to the row over the subsidy for the interconnector, which is now resolved apparently and a new permission is going through the system now. I just took a look at that application actually and I hadn't realised that it's based on an FSRU rather than permanent onshore infrastructure.

    If demand drops in future, the FSRU won't be going anywhere as it likely means demand for NG has dropped all over the world due to the advancement of renewables. This is why gas produces and suppliers are desperate to lock governments into long term contracts, they know where the market is heading.

    I don't think it follows that Ireland no longer needing an FSRU means nobody would have a need for them. Conditions aren't identical everywhere in the world and we're in a pretty unique situation regarding potential for wind generation here that others aren't.

    As a matter of interest where is this coming from that gas usage is going to decrease by 80%? Apparently, the National Energy and Climate Change Plan 2021-2030 has gas usage increasing.

    Some confusion maybe with the target of 80% of electricity being renewable?

    As the electricity usage will be rising fast due to EVs and heat pumps etc...the actual amount of gas may not be declining too much. I'm sure the estimate has been published somewhere though.

    Found in climate action plan: 2GW of new gas generation required.



  • Registered Users Posts: 7,146 ✭✭✭plodder


    Interesting article about LNG expansion in the UK with some figures that relate to here.

    17% of UK gas is LNG

    From January to September this year, of 175 shipments: 51 from Qatar and 81 from US (which one presumes are fracked gas)

    So, 7.8% of UK supply is fracked US gas and that is set to increase.

    Separately, 80% dependence on imports by mid 2020's in Ireland (90% by 2030) which means 6.2% of Irish gas is already fracked (or will be within a couple of years) and increasing from there in line with whatever the UK decides.

    The Welsh expansion will increase its output from 15 million tonnes to 20 million. More interesting, is that new export facilities in the US including Golden Pass in Texas will increase US output by 85 million tonnes by 2025, which is way more than the UK can accept, so is highly likely to end up elsewhere in Europe.

    We’re happy to take fracked gas as long as it comes through a terminal in Milford Haven and not Ballylongford. “Arms length” if you will.

    Same way we are more than happy to use nuclear generated electricity, just as long as it’s produced by a “réacteur nucléaire” and not at Carnsore Point



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 22,540 Mod ✭✭✭✭bk


    Not that much different from how the UK is happy to import fracked gas from abroad, but has banned fracking in the UK.

    The above certainly puts to rest the pretty ridiculous claim that some folks were making earlier that the Shannon LNG terminal wouldn’t be importing fracked gas.

    But the whole fracking thing is largely beside the point. While some may object to LNG terminals based on fracking, it certainly isn’t the main issue with us building one. The issues are who pays for it, will it increase costs to consumer, will it tie us into gas long term when we should be transitioning away and really what is the benefit when we can just use the UK LNG terminals to import gas anyway.

    DAA given planning approval for a 26 acre solar farm - can't see the MW for this.

    Recent ETTG report on a private 5.2MW 19 acre solar farm in Cork - interesting mix of solar/wind. Also outlines some of the obstacles encountered in bringing it online.




  • Posts: 0 [Deleted User]


    So there's an exclusion zone for several km around the airport where nobody can have solar panels but the airport themselves can have a 26 acre one within a stones throw of the runways.

    What am I missing?



  • Registered Users Posts: 231 ✭✭specialbyte


    They are called Solar Safeguarding Zones. Here's a map of them: https://housinggovie.maps.arcgis.com/apps/instant/basic/index.html?appid=5d9bad421ce242b280cd709d4c50afca

    Inside of those zones you need to apply for planning permission if you are proposing more than 300sqm of panels, which is roughly 45-70KWp. It's the same as 7-12 houses worth of solar panels.

    Outside of those zones putting solar panels on rooftops of most classes of building doesn't require planning permission.

    Ahh I thought they were exclusion zones, thanks for the clarification



  • Moderators, Science, Health & Environment Moderators Posts: 19,421 Mod ✭✭✭✭Sam Russell


    Basically, the restriction is to check for reflections causing problems for pilots.



  • Registered Users Posts: 480 ✭✭getoutadodge


    I heard ER yesterday respond to the idea of expanding the Corrib Field to extend its expected life span. The answer was a definitive NO. Fanatics. In the meantime we'll be importing ever more US sourced fracked gas from the UK system....if we can get it. A party with 3 per cent dictating policy in the teeth of an energy crisis.

    By the looks of things, Ireland has had to curtail wind generation so far today such is the volume of energy being generated from wind. The interconnectors have been flat out for a good chunk of the morning where there is a limited gap between demand and wind generation above also (the UK in turn are consistantly exporting 2.5-3GW to France all morning so it's a case of everyone helping each other out). Wind generation is forecast to peak at just below 5GW (which would be an all time peak) at peak time this evening.

    As time marches on it's clear we'll have to find a use for all this surplus energy. Going by today's flows an interconnector to France as is planned would be a ferociously handy asset.

    Adding additional data centres (24hr steady demand) with gas peakers in Ireland would seem a fairly green way to power this need which is going to have to be located somewhere. Much better having them in Ireland powered by wind and gas than elsewhere powered by coal. Of course the ideological greenies would rather them offshored so we can hold up our own moronic national climate targets and blow our own trumpet to the detriment of the planet they care so much about.



  • Registered Users Posts: 4,676 ✭✭✭serfboard


    AFAIK, the proposed best green practices for excess energy are exporting, giant batteries and hydrogen generation.



  • Registered Users Posts: 3,777 ✭✭✭Apogee


    Updated info on list of wind farm projects from earlier.

    Clare Offshore (No 18) seems to be now called 'Clarus Offshore Wind farm' (DP Energy/Iberdola) using floating platforms up to 1GW.
