No, nuclear has never produced much waste. The total amount the UK has produced to date would fit into a few large 'sheds' on the sort you see on an industrial estate.My understanding of the issue here is that reactor design hasnt really moved on, and still produce lots of waste.
Both conventional ones that 'burn' more fuel and things like LFTR that are different in principle.I know there are a number of programmes globally looking to address this with safer, low waste reactor designs.
Any sources for that?The price of batteries dropped by 87% in 2010-2020, they dropped 13% last year.
You can make anything look cheap by comparing it to the right other object. Part of the reason there is a lot of research into other technologies is because lithium is so expensive.Also, Lithium is cheap.
Once again, I have no idea what you mean. Some peaking plants are OOGT and are less efficient but are not polluting. I have never heard of a CCGT plant that takes more than a few minutes to start and maybe half an hour to get up to maximum efficiency. I have no idea why you think they take days to start.For short term peaks you have the incredibly expensive, polluting peaker plants that can spin up in minutes rather than hours or days like the big cheap gas plants.
Goody. A problem that we never used to have and was only introduced by adding loads of expensive unreliables to the grid is going to be solved at even more expense.Short term stability isn't going to be an issue for much longer.
Utter nonsense. IF SA had a reliable grid there would be need for Hornsdale. And it has been so successful only because the grid in SA has been so unreliable.And the reason they're used at the moment is to make money, Hornsdale has done better than it was predicted for both it's investors and the SA public.
Which basically amount to zero when compared to the size of the grid.apparently we've got around a GW of installed grid batteries
You seem to have written 'decent' when you meant 'miniscule'. Batteries can possibly be a useful, albeit very minor, part of balancing the grid, but I get a bit irritated when people talk about how big they are are refer to them as grid-scale when they are so relatively small. UK electricity consumption is c. 850GWh/day.that's a decent 320MW/640MWh one though.
BTW,
Responding to "[Batteries have] already undercut the business case for peaked plants entirely as they're too expensive and slow to make sense." I said
Really? Any numbers to back that up?
Responding to "The advantage [of LAES] is that you can keep that power for a long time at minimal cost." I said
How does that compare to storing the equivalent amount of energy as natural gas?
