    hydrogen is far more volatile - at an elemental level it bonds with so much that its very difficult to keep in its pure state as hydrogen gas.

    One of the big issues with hydrogen vehicles also is the volatility of the fuel. It is far from stable

    The same reasons why Nuclear didn't take off in australia also apply here. Its too expensive, and there is a political opposition to nuclear due to the British dumping radioactive waste on our territory (in the irish sea)

    It was also about the cost being too high compared to the alternatives, Nuclear was much more expensive than coal. Now Nuclear is much more expensive than solar and wind combined, which are becoming cheaper than coal, so there still is no real argument for nuclear power in Australia

    https://www.climatecouncil.org.au/new-wind-and-solar-now-as-cheap-as-existing-coal/

    Other than just thinking nuclear is futuristic and cool, what is your argument for building Nuclear in Australia given how successful south Australia has been with Solar and wind over the past few years?

    Why would you need to pick between 2 non mutually exclusive statements?

    You might as well have said


    -----

    "Climate change is real"

    "Summer is always going to be warmer than winter on average"

    take your pick

    The only thing your comment demonstrates, is a lack of understanding about climate or logic

    Can you show me a country that has nuclear power where consumers pay more for electricity than we do?

    Germany are worst because they turned of their nukes and instituted a massive levy to subsidise renewables, which fell over when the wind stopped blowing. Look at Denmarks prices!! The supposed low cost of renewable generated electricity is a lie.

    Please don't mention solar, it's the most fatuous and risible potential energy source for this country imaginable. Herds of cat's, chasing mice inside wheels would almost make more sense.

    Ireland only has sunshine for 14% of the hours in a year. When it's cloudy, which is a depressing 72% of potential 'daylight' hours, the energy generated drops to only 18% of a panels rated potential. It's a bad joke.

    Electricity prices in Ireland are high because of the stupid dispersed settlement pattern that has allowed one-off housing for decades in rural areas.

    You do love to get worked up over renewables, but don't bat an eye at the idea of nuke fuel and waste travelling up and down the roads of Ireland or the dangers of the nuke option when things go wrong.....but of course, this time it will be different lol

    Nuke power generation here has been legislated against so there will never be a nuke plant on this island as no politician is going to vote to allow it

    If you thought people were pissed at the idea of water charges, imagine the uproar if you said to the folks in county W that there was going to be a nuke plant built there and to the folks in counties X, Y & Z that the nuclear fuel was going to be transported on roads that go close to their towns and villages.

    Then tell them that we won't be getting rid of the waste, instead its going to sit around, beside the plant, for the next 50 years until there is enough of it to justify building some permanent storage underground.

    Oh and don't forget to tell them that they will be paying many multiples of the going unit price just to subsidise the plant as its horribly expensive to build

    Face it, its never going to happen

    Rural areas have these things called farms. I know it's crazy, but they have had electricity supplied to them due to a distinct shortage of lasses willing to sit on hard stools for hours, fondling cow teats.

    Please make out your argument that farms should never have been provided with electricity or phone lines, I do enjoy good comedy.

    The number of one-off houses is around four times the number of farms.



  • Registered Users, Registered Users 2 Posts: 7,632 ✭✭✭timmyntc


    Blaming our electricity prices on rural housing is the most ridiculous argument i've heard in a long time.

    Are you saying that the cost of keeping power infrastructure to rural ireland is the reason our electricity costs so much? Because its a bold (and incorrect) statement.



  • Registered Users, Registered Users 2 Posts: 997 ✭✭✭iColdFusion


    Might want to have a think about where all the inland wind farms are being built and the vast new power networks involved in feeding that power to Dublin and its data centers, realistically most of the rural grid is over 50 years old and has no impact on current electricity prices. Lets not the forget the ESB is 95% state owned and was setup with the main purpose of bringing electricity to everywhere in Ireland.

    Alas, it turns out if you just turn it into particulates and blow it into the air for everyone to breath in people care far less.

    "marginal cost

    noun

    1. The increase in total cost of production as a result of producing one more unit of output; since certain ovrhead costs are fixed, the marginal cost is almost aways less than the total per-unit cost of production averaged over all units produced.
    2. The increase in cost that accompanies a unit increase in output; the partial derivative of the cost function with respect to output. Additional cost associated with producing one more unit of output.
    3. the increase or decrease in costs as a result of one more or one less unit of output"

    Consider the cost involved in this photo:

    Untitled Image

    What do you think was going on here? Was it:

    A) Connection a new one-of rural house to the grid

    B) Routine maintainace of infrastructure serving a one off rural house

    C) Installing a tranformer for the farm on the left


    One-off Houses are irrelevant, beyond actually bringing down the average cost of electricity provision to farms.

    The only issue I can see with transitioning from methane to hydrogen in our gas network is the transitioning point for end users. Boilers, cookers & fires will need to be updated to run on hydrogen instead of methane. If an area is switched from methane to hydrogen, then all of the appliances have to changed at the same time. There are approximately 700,000 homes connected to the gas network, and without having a solution for these users the existing pipework won't be available to hold hydrogen.

    I think that there needs to be a managed migration away from natural gas in a domestic environment. We need to continue the move towards electrification of all heating and cooking. There shouldn't be any new domestic connections to the gas network allowed, and there should be some plan to move existing users off the gas network. This should be planned on an area by area basis to facilitate the decommissioning of the gas network in an area. It should also have a long enough lead time that there won't be a large number of homeowners trying to replace their boilers at the same time. The lead time should be long enough that as people get to the point where their boiler needs replacing, that they move to an electrified heat source. Then, when there is only a small number of gas connections left, the remaining customers can be notified that the gas supply is going to be disconnected on x date.

    At the same time, gas power stations will need to be converted to run on hydrogen if the pipelines feeding the country are changed from natural gas to hydrogen. This will work well if we increase our renewable electricity production, as excess electrical energy can be used to generate hydrogen. If we have enough excess electricity, then we can become a net energy exporter.

    If there isn't a plan to wean the market off natural gas, then there will be a problem sourcing natural gas if the large pipeline interconnectors are converted to hydrogen.

    Oil boilers in new builds are banned next year, gas boilers banned in 2025 but they are effectively banned now under Part L to get your A2 BER and most builders have been fine with this for last few years as they don't have to run gas lines throughout a new housing estate when they can just put in a heat pump.

    Its also very possible to transition homes with their own LPG tank to hydrogen as its a standalone system but not sure if hydrogen has particular storage requirements above your normal LPG tank in the garden.

    For hundreds of years ships relied purely on wind power to travel around the world. If wind is “random” then it’s a miracle Magellan got as far as he did.

    Existing pipework won't hold hydrogen, hydrogen isn't suitable for gas cooking



  • Registered Users, Registered Users 2 Posts: 21,091 ✭✭✭✭cnocbui


    Yes, but you don't genuinely want an answer so I shall withold it.


    "The Big Wait

    Here we are - becalmed again after several days of really good progress with steady winds and slight to moderate seas. In a wind hole, which is that curse of sailors (see my Leg 1 blog)."

    ...

    6 references to being becallmed on a sailing ship taking immigrants to NZ.

    I don't suppose you have ever given a thought to the origin of the word 'becallmed' and to what activity it pertains?



  • Registered Users, Registered Users 2 Posts: 8,135 ✭✭✭Jinglejangle69


    And who cares about all those trades people who look after boilers etc?


    Sure they don't matter, to hell with them.



  • Registered Users, Registered Users 2 Posts: 8,135 ✭✭✭Jinglejangle69


    Eh methane is not heavier than air?????


    Jesus if this is the science we are led to believe to make us more greener I fear for our lives in other ways than climate change.

    Providing electricity to dispersed one-off homes is between two and five times more expensive than to clustered settlements. There is power loss on the grid and the ESB must maintain an unusually large infrastructure for our population. There is a 'rural tariff' so to speak but it has never covered the true cost of the increased cost of provision of electricity.

    It's a perfect example of the costs of one-off housing being externalized on to everyone else.



  • Posts: 15,362 ✭✭✭✭ [Deleted User]


    I think @Akrasia mis-spoke as, what we use here are butane or propane, and both are heavier than air.



  • Registered Users, Registered Users 2 Posts: 8,135 ✭✭✭Jinglejangle69


    Back to school for you aswell.


    We use methane, butane and propane here.


    Hard luck lads.

    What’s your angle here? You want to do away with one off housing completely? Bulldoze any one off housing that’s not a farm and move everyone into a town?

    It’s just the way it is. There is no longer any substantial construction of new one off housing.

    We all pay for many things that don’t benefit ourselves

    Hey, every day is a school day they say :)

    So LPG is butane and propane and some other bits. Buying barrels of bas down the store, you'll get these. These are what I'm familiar with myself.

    Natural gas, pumped through our gas network, is methane
