I actually think we need Nuclear as a bridge between fosil and other
fuels.
There are no other viable fuels.
Apparently, fusion is now only 20 years away - a big advance on the 50
years away it was, umm ... 50 years ago.
Pure speculation on my part, but would it be possible to "fix" the CO2
captured and stored from gas/coal power stations, into methane or even
alcohols using spare electrical power from wind turbines?

Eminentlyf easible. It takes exactly the sameamount of energy to
"fix" the the CO2 as was liberated whenit was produced......In theory.
In practice maybe ten times more.

ten times about right,.
30% coalpower station efficency and probaby 30% hydrocarbon synthesis
efficiency. Rest is waste heat,.

BUT that makes nuclear synthesised diesel represent something like
150p-200p a liter in terms of cost of electricity.

Compared with about 50p out of the ground.
