I watch Gridwatch and strangely when it is overcast and the sun does not shine, renewables fall from 50% of output to 20odd %...

We have 39 Gas powered stations and they are producing 50% of demand. They will be closed when we are carbon neutral..

Are candles carbon neutral ?

You can't run a country using fans on sticks for your power supply......

We might be better applying some creativity to this rather than just cold water.

Like storing energy in liquified air.

Saw the tail end of a programme about the National Grid a night or two ago. They were talking about the Drax power station in Yorkshire. It's moving or has moved to using biomass and the programme indicated that there were no plans to close it.

Drax have been converting to imported biomass for many years, and will stop burning coal altogether next year.

Many coal fired stations have been burning some proportion of biomass, the one near me was burning all sorts of wierd and wonderful things before it closed last year. Olive pressings was fairly regular, they burned them overnight and brown spots appeared on cars - they flat denied it, but we knew people that worked on the haulage... and you could smell it!

Willow and elephant grass is also grown locally for electricity generation.

I've got my doubts about biomass too.
Renewable yes. Carbon neutral. I doubt it.
The argument for biomass is that replacement trees absorb carbon dioxide but trees grow slowly and wood can be burned quickly. Are the trees even replaced? They could be being cleared for building or agriculture

I think a lot of the wood comes in the form of pellets from USA. The wood is supposed to be scraps of waste wood but I suspect that much of it could be put to better use.
Transporting pellets from USA is hardly environmentally friendly either.

Before it shut the Longannet power station was experimenting  with burning dried sewage.

BOC and other gas companies have been making liquid air for a long, long time.

Yep, the Biomass (wood) pellets for Drax come into Liverpool and are then loaded onto specially designated goods train which take the 'cheap route' through Rochdale and Calderdale to get to Drax, rather than the express line through Manchester and Huddersfield where they might risk delaying an airport express!

Before Lockdown 1.0, when I was commuting on the Calderdale line to Leeds, at 0630, my train would often be delayed by one of these Drax trains coming through. Far easier to stop a two coach commuter train than long goods train. You could smell the wood though, it was unmistakable and strangely evocative.

Quite eerie, standing on the platform at Sowerby Bridge as this train approached from the dark, pulling a minimum of 20 wagons of biomass. By the time the diesel engine had gone through and half a dozen wagons had passed, you could no longer hear the engine so wagon after wagon would go past very quietly and disappear again off into the gloom.

Yes, but not to store energy.

I agree, importing raw materials to burn from the the other side of the world has to be costly, both monetary and environmental.

Not only that, some of the sources of these pellets are somewhat murky, with some traced back to illegal logging being mixed in with certified sources. Some say that the vast size of the certified trade is encouraging illegal deforestation.

The sale of new petrol and diesel cars will be banned within a decade, Boris Johnson is set to announce next week as part of a broader package of green initiatives.
In February, Mr Johnson announced that the existing ban on selling new petrol or diesel cars would be brought forward from 2040 to 2035.
Now the prime minister is expected to move the date forward to 2030 in an attempt to jump-start the market for electric cars in the UK and push Britain towards its climate goal, according to industry and Whitehall figures.
However, the government is expected to keep the less stringent date of 2035 for the phase-out of the sale of hybrid cars that plug in to charge.

This change from petrol/diesel will be another disaster.

How long will petrol/diesel still be available.

There are about 40 million cars curently so that's quite a few charging points needed to cater for even half that. Best of luck if you live and park along a long victorian terrace with no driveways.
Let's be careful out there!
