Anyone know anything about these new "battery barns" that the subsidy farming companies are trying to set up? The idea is to charge them from the grid at certain times and then release it back when needed. There's a planning application for one near our village. It's huge - about fifty metres long!
Any info in the PA about capacity, MWh, how long it'll supply the grid for, flat out, that sort of thing, bearing in mind that the UK consumes something in the region of 800-900GWh of electrical energy per day? I'm not suggesting this one will have anything like that capacity, it won't come remotely near it, but I'm passingly interested. The pumped storage facility at Dinorwig can supply approximately 1.7GW for six hours.
Someone phoned me today to try and get me to fit a solar battery and panels. They decided to hang up when I asked them how many hundreds of panels I would need to charge the battery and supply all my electricity even in winter.
I think its about 10 sq meters per kwhr in winter and about 20% of that in summer. How many kwh do you get from your two 4kwp arrays in winter?
No more than say 100 tonnes of TNT stored in as shed.
All googling reveals is PR and marketing lies.
It seems likely that a typical barn might be 10MW with a capacity of around 50MWh. Lithium batteries in racks. The ones that you are not allowed to take on planes because they catch fire.
At a guess lithium batteries at that scale would be around £500/Kwh, so this size of barn would represent £5m or so.
I reckon a Dinorwig would cost about a billion these days for 10GWh. Far cheaper and lasts longer.
Which is about the same energy as 43 tonnes of TNT. Which would be released if they got shorted. Internally. Accidentally.
But this is a guess and no one is actually quoting real numbers.
Of course they will sail through planning just like bird mincers and bat exploders do, and the only class of rotating industrial machinery apart from aircraft propellers that is allowed to be operated without a safety guard.
Sigh. The whole point of brexit was to ditch this renewable shit and build gas power stations and nukes.
What projected outlay is there for the tax payer? It sounds limited to infinity. What is the battery life expectancy? And how much does it cost to set up and run a nuclear power plant?
How are they ging to get power into the system? If it was a worthwhile proposition why have the power companies invested in it? Such a thing would be cheaper than the Dinorwic Project was.
Harry put that link up earlier. I saw nothing about capacity (MWh), how long the individual batteries last before they need replacing, or cost, either installation cost or ongoing maintenance cost. It struck me as typical renewable energy spin: long on sales talk and hype, short on facts and detail.
