Climate change: Ban new gas boilers from 2025 to reach net-zero

A ban on new gas boilers from 2025 is one step to reach net-zero emissions by 2050, say energy experts.

Hopefully the solution will be the development of the controlled fusion nuclear reactor. One small step closer? Mast Upgrade: UK experiment could sweep aside fusion hurdle - https://www.bbc.co.uk/news/science-environment-57232644

The future is bright. Look up Solid State batteries. A game changer.

I caught a bit last night on the news... apparently... Orkney is in such a situation and they do exactly that... using surplus 'green' electricity to make hydrogen.

My 'ideal' little home solution would be to have the entire roof covered with PV panels, then make hydrogen with the surplus. This could then fuel the Toyota Mirai hydrogen car. Just need a hydrogen powered van too. Using grid power from the cheapest hours would supplement the system in the winter etc.

All heating/hot water would be via ground source heat pump into a thermal store.

Only watched the first one so far ...

Key things to note :
Small island, so nowhere much to drive to - so little range anxiety. And of course, you don't need to worry about not being able to charge for a day or two (if conditions aren't right) since for most people, they aren't going to be able to put the miles in to run out of charge.
At the time of visiting the windmill, the 4.5MW windmill is generating 20kW - just 0.44% of it's rating. Do the maths sensibly, rather than the "lets make impressive numbers" approach they've used, and the average generation is 470kW - only 9.6% of it's rating plate output. Hmm ...
Each battery container, 1MW, 1/2MWHr - no mention of the costs, they ain't cheap ! Can't even substitute for the one windmill for one hour.

And only at the end does he hint that they are reliant on the interconnect to avoid the lights going out when the renewables aren't meeting demand. Plenty of gusto about exporting excess, naff all mention of being reliant on the mainland for balancing.

And that's where it breaks down. 2000 people on a sparsely populated island, 700 generating points, and reliant on the rest of the UK for balancing. Now scale that up UK wide ... lets say 60 million people to keep the numbers simple. So multiply everything by 60,000,000/2,000, or 30,000.
Over 20 million generating points. We have (IIRC) something like 30 million properties, many of which are not suitable for solar panels or windmills. And think 90,000 40ft containers of batteries and you still can't balance the grid with the batteries.

Certainly an indicator of what's possible - but not the "problem solved, just scale it up" proposition many renewables apologists like to peddle.

Not a million miles from the image posted by Mike, but this one was a more permanent arrangement.

The only island I know of that has truly managed to get 100% electricity needs without an interconnect to the grid at all is the Isle of Eigg.

The OU use them as an example and require reports on them for a couple of their energy and sustainability engineering modules. I don’t know if they have completely removed all diesel generator backups, but I believe they have. That was certainly the intention when they created and installed the scheme.

However, Eigg is tiny and while it’s a great example of what is possible it shows the trouble with scaling the idea up. They have a lot of generating capacity for a small area and population and they had the huge benefit of having zero existing infrastructure. They could install what they needed where it was most effective without worrying about upsetting farmers and landowners!

Generating hydrogen in low demand, acts as an energy buffer, to fill in when wind, tide and wave are at a lull. It is all about storage. Currently electricity is generated on demand. It used as it is being generated.

Range anxiety? A friend owns a Tesla, living in the Lakes. It has a range of around 220 miles. Going to London the battery just about handles it. He said the range is his bladder. He stops for a pee and coffee on the way down and back - which we should all do on trips like that. Each stop, 50-60 miles of charge is put into his battery. Buzzing around the Lakes and beyond he has no problems whatsoever, as he charges at home. He wakes up each morning with a full tank - topping up while he watches TV or sleeps. The cost of energy to run teh car is bitton to buying smelly petrol.

No, this is not a petrol generator charging an electric car

A photo shared at least 75,000 times on Facebook allegedly shows a diesel van towing a petrol generator in order to charge an electric car. This is misleading; while the Austrian roadside assistance association that owns the mobile charging station in the photo confirmed to AFP it relies mostly...

Ooooops wrong post!! my mistake

I actually read the why for that. there is a reason. Its a stop gap solution to roll out ultra rural charge points, end game is swapping the diesel genny out for solar, which makes sense in rural australia...
Seemingly equivalent mpg is the same as a diesel or slightly better as the genset runs at a consistent rpm...
Guy admits its not ideal but its only part of the journey...

Using diesel to charge EVs in the outback is greener than you think

A group of EV drivers test out using an EV charger powered by a diesel generator as a solution for outback roadhouses, and the results are promising.

Given that it is Australia, it seemed likely that some solution had to be found (temporary or otherwise) for very remote locations.

Certainly made me smile when I first saw it ?
