And I have pointed out the unbelieveable risks and costs assocaited with that incredibly stupid iudea Hydrogen is expensive but if you have over capacity you might as well do something with it. We do not have enough mountains to pump water up. We do actually. Just. In the end its all cost benefit analysis driven. How much do you value CO2 emission at? The higher the cost of then the more nukes and the less gas power. *Renewables are never the cost effective option*, ever. And political. The most likely sites are in Wales/Scotland. There was a huge upset (early '60's) with the Clywedog *flood control* scheme when the Welsh Nationalists claimed the stored water was going to be pumped out of the R. Severn and over the hill to supply London. A second similar scheme was dropped because the chosen valley was inhabited. -- Tim Lamb |

That may well be true, but given https://en.wikipedia.org/wiki/List_o...power_stations it doesnt appear that they have any more pumped storage than the UK and use the different fuel rod approach for handling the varying load on their system instead of pumped storage. But that doesnt actually list the MWh of their's. They have significantly more hydro power. Thats a separate issue to how best to handle the varying load on nukes. Pumped and hydro (dams) can serve the purpose, load balancing, rapid dispatch. How the water gets to the top of the mountain doesn't really matter. The French also use fossil fuels for heating. Another separate issue to varying load on the nukes. It is most efficient to run Nukes flat out. France Nukes produce too much in summer and too little in winter. Hence extra seasonal (winter) generation power is balancing the Nukes. Pumped Hydro, is short term balancing, minutes/hours. Coal and gas is seasonal balancing. |

Those other solutions may be OK for very short term peak-lopping, but none are capable of storing the amounts of energy needed to run the country for a several days at this time of year, OK, I was seeing quotes of hydrogen storage providingÂ* months energy supply as opposed to a few hours for pumped storage.

The volume would be absolutely huge, even if compressed. The phrase 'greens don't do sums' is occasionally trotted out on this NG. That looks like a classic example of just that. AND: Where is the capacity coming from? Unreliables, supported by nuclear? Bear in mind that whatever unreliable is being used as the primary generator, when the 'battery' (in whatever form that might be) gets substantially discharged, not only will the primary generators have to supply the ongoing day-to-day demand, they will also have to recharge that 'battery' PDQ, in anticipation of another generation-free period in a week or so's time. How much extra generating capacity that might need, I don't know, but substantial, I would think. Â* That problem doesn't arise with nuclear. A large battery gives plenty of time for a battery to recharge, two months is a big battery. I don't understand what you're saying there. A large 'battery', of whatever type, would take a long time to recharge from flat, when speed would be of the essence in time for the next lull in the weather with no generation from unreliables. The idea of a battery is to smooth out variance. To allow for supply to match demand. With a big enough battery we just need average energy production to match average energy demand. Without a big enough battery we need overcapacity. Hasn't this point been made many times? Actually the problem does occur with nuclear, too. You need rapid dispatch to counter the variability of demand. But nuclear is dispatchable; not ideal (they're best run flat-out AIUI), but it's not difficult. Yes, but is it optimal? You would need enough nuclear capacity to match maximum demand, also turning it down can cause difficulty. At some point it might be cheaper to have fewer nuclear power stations generating full all the time. When they have spare capacity they generate hydrogen, in periods of high demand they use the hydrogen to fuel rapid dispatch generators. No point. Cheaper to add a little more pumped storage Or gas. I'm pretty sure you have already pointed out we cannot have months of energy stored in pump storage. We donmt NEED to. we just need enough for daily peaks, with nuclear. Only with renewable energy do we need a winters worth. Yes we could use natural gas or burn coal, but the idea we are discussing is to avoid CO2 emissions. Then use nukes. And pumped strorage. That is all you actually NEED. It might be cheaper to use excess Nuke capacity in summer to produce hydrogen rather than build extra Nukes to cover winter demand. This is especially true in the UK if we want to replace domestic heating, to lower CO2 emissions. |

To power the UK for a day, just on electricity, in winter, takes about 24 hours at an average of 35Gw = 840GWh In terms of nuclear warheads, that is 722 kilotons. 50 Hiroshimas. Would you rather live: (a) near a nuclear power station that cannot explode, only melt down inside a safe containment vessel? (b) near a megaton explosion capable hydrogen store? Note: a megaton explosion takes outÂ* about 100 sq km absolutely. Remind me, how many gas wells have exploded with megaton explosions. Wells only a few. Storage facilities for gas...one or two with devastating results No megaton explosions, then. Gosh, I am surprised. https://en.wikipedia.org/wiki/Gas_explosion Note that nearly all of these killed more people than chernobyl and ALL of them killed more people than Fukushimas recator did. "Note: a megaton explosion takes outÂ* about 100 sq km absolutely." The idea is to support what you actually claimed not start an irrelevant tangent. The point is that no one has been STUPID enough to build a seriously large hydrogen store of the sort that you are proposing since gas at far smaller levels has killed tens of thousands Erm, where? Or do you mean Bhopal, which wasn't hydrogen and wasn't an explosion. Because I'm not seeing any megaton hydrogen explosions. |

But none of it comes near to pumped storage in terms of capacity, and that's very dependent on the right topography, most of which has already been used. Those other solutions may be OK for very short term peak-lopping, but none are capable of storing the amounts of energy needed to run the country for a several days at this time of year, OK, I was seeing quotes of hydrogen storage providingÂ* months energy supply as opposed to a few hours for pumped storage. The main difference being hydrogen is 40% efficient where as pumped is 80% efficient. But how and where are they going to store a month's worth of hydrogen? The volume would be absolutely huge, even if compressed. The phrase 'greens don't do sums' is occasionally trotted out on this NG. That looks like a classic example of just that. To power the UK for a day, just on electricity, in winter, takes about 24 hours at an average of 35Gw = 840GWh In terms of nuclear warheads, that is 722 kilotons. 50 Hiroshimas. Would you rather live: (a) near a nuclear power station that cannot explode, only melt down inside a safe containment vessel? (b) near a megaton explosion capable hydrogen store? Note: a megaton explosion takes outÂ* about 100 sq km absolutely. Remind me, how many gas wells have exploded with megaton explosions. Wells only a few. Storage facilities for gas...one or two with devastating results No megaton explosions, then. Gosh, I am surprised. https://en.wikipedia.org/wiki/Gas_explosion Note that nearly all of these killed more people than chernobyl and ALL of them killed more people than Fukushimas recator did. "Note: a megaton explosion takes outÂ* about 100 sq km absolutely." The idea is to support what you actually claimed not start an irrelevant tangent. The point is that no one has been STUPID enough to build a seriously large hydrogen store of the sort that you are proposing since gas at far smaller levels has killed tens of thousands Erm, where? Or do you mean Bhopal, which wasn't hydrogen and wasn't an explosion. Of FFS just tot up all the deaths from gas explosions overte last 50 years and compare with all the deaths from nucler Because I'm not seeing any megaton hydrogen explosions. Why would you?

OK, what am I missing? France Nukes produce too much in summer and too little in winter. But even easier to have some nukes offline in summer and enough so you can generate all you need in winter than to spend immense amounts of money on hydrogen for that problem. OK. The problem is that nuclear power stations currently cost a tremendous amount to build, they cost very little to run, they generate a lot of revenue when they do run. In many ways this is very like wind turbines, the following argument is the same for both nuclear and wind. In order to be economic the cost of building has to be recovered from the total profit of them working, over their fixed lifetime. If you turn them off for summer, you don't make any profit for that proportion of their lifetime. Even if they only get a fraction of their normal price for electricity in summer it can still be economic to run them, they still make a profit. Hence hydrogen production at 40% efficiency is economic. It still helps generate profit to offset the cost of building them.

The problem is that nuclear power stations currently cost a tremendous amount to build, Only because of the stupid over regulation imposed by the EU. That wasnt the case when france did their nukes originally and they didnt have any major problems with that earlier approach to nukes. they cost very little to run, Even when the fuel rods arent used most efficiently when some of the nukes are not run flat out. they generate a lot of revenue when they do run. In many ways this is very like wind turbines, Nothing like in the sense that how they are run is completely up to those running them, not up to the weather. the following argument is the same for both nuclear and wind. Bull**** it is. In order to be economic the cost of building has to be recovered from the total profit of them working, over their fixed lifetime. If you turn them off for summer, You only turn a minor subset off for summer and that needs to be done for maintenance anyway, you don't make any profit for that proportion of their lifetime. But that clearly worked fine for the french system. Even if they only get a fraction of their normal price for electricity in summer it can still be economic to run them, they still make a profit.

That clearly wasnt necessary with the french system. With nuclear it may be confusing that you think the fuel rod approach is better because it saves money, I never said that. I JUST said that given the cost of the fuel is a minor part of the cost of nukes, it doesnt matter if they arent run at full power all the time to get the best out of them. Its much cheaper to replace them when they arent used most efficiently than to fart around with the immense cost of the hydrogen approach. by saving fuel, but AIUI is doesn't even save fuel.
