Why aren't you creating a new business rather than waiting to tag along with someone else's? I have always created my own and had other people join me. This is not a criticism: something in that gap may be useful in your search.

Interesting limited offer with OK Ts&Cs. Won't apply to many, need to be fairly affluent to be in scope, but free heat pump as marketing hook is fairly novel...

The implied locale of those logging levels is (US) English though. And so any recasing of them should be in that locale.

Indeed possible and both will probably happen. If you put your H2 hydrolysers and turbines or fuel cells near the H2 store then handlng and distribution becomes easier. Move the electricity not the H2.

Show me a field deployment of GaAs! That stuff is so expensive AFAIK that it's almost only for space applications, though things may have moved since I last looked! Most solar is monocrystalline Si with tiny amounts of dopants such as

We wouldn't site coal (or nuke) generation there now because (a) we can do long-distance low-loss transmission (in GB, transmission losses are ~2%, distribution losses ~5%), and because we know about the bad effects of the air pollutio

Not being able (or willing) to turn turn nukes down or off to load-follow makes them sometimes as difficult to work with as intermittents. None in the GB grid load-follow, though one can AFAIK. And nukes need refuelling, so you need to fi

Renewables-hydrolysed hydrogen stored in the caverns where we currently store methane is quite likely a big part of the interseasonal energy solution.

Yes, but no GB nukes load-follow either, so the same issue. Economy 7 off-peak rate was invented to soak up some nuke power unused by industry in the night, IIRC. "Cannot turn off" power can be as tricky to manage as "cannot

I picked those two because they happened to come up in news items in the last 48h or so and were in my head. The UK also has a huge amount of roof-top PV potential, outside the very dense city cores, plus enough golf course space to cover a

No generator runs 100%. Not so long ago the UK nuke fleet was managing only about 60% caopacity factor. The grid system runs as a whole with generators backing one another up. The last two big load shedding incidents (since the turn of t

For the UK there is more wind in the winter, solar in the summer. Intraday anti-correlation is there, but it's more complicated: https://bmrs.elexon.co.uk/generation-forecast-for-wind-and-s... The US picture varies a l

There is no coal-fired electricity generation in the UK now. But no, neither coal nor nukes would be welcome in cities just to reduce transmission costs!

Wind + solar + batteries at one site can be a good combo.

If UK golf courses were turned over entirely to solar PV that would more than cover the ~30GW extra called for in the UK's Clean Power 2030 plan, IIRC. I would regard that as a huge improvement in use from areas that are otherwise ofte

We generally don't like to put our nukes (or coal plant) in the centre of cities even though that would reduce transmission costs, nor are major hydro resources often close to the areas that power from them goes to. So that is not uni

Because solar (for example) can often go on rooftops so not needing new land. And solar and wind are often good in remote areas where population is low and land is cheap.

by DamonHD 1y ago
Capacity factor for renewables is generally lower than thermal plant, so some transmission costs may be higher. Though batteries firming output mitigates that for example.

UK insolation is very roughly half that of (say) California, IIRC... (BTW, this is my crowd at Surrey, and Ravi is my (IfS) director!)

That design started ~10Y ago. If I was starting again I might pick something different.
