Anyway, whether it's e-fuels or not, $8/MWh over a large portion of the world's surface makes many problems go away.

Ugh, ignore these numbers, I'm going to stop doing calculations at 11pm when I have already done them somewhere else but can't be bothered to dig them out. But the energy use for the DAC is the big problem, it uses more than the actual synthesis.

The gas will have gone away long before 5 GW of extra nukes come online! Agreed it gets complicated when you get to 95% low carbon especially when you try to predict extra demand (how much AC is there going to be in the UK?) and incorporating DSR with electrified industry.

There is much playing around with numbers you can do to get low prices. Fundamentally a 50% efficiency for the electrosynthesis gives you ~$1.40 per litre wholesale just for the electricity at $0.08/kWh. Probably you would be lucky to get that unless you get free heat for the DAC.

Yes but we still get cheaper electricity from burning less gas in summer. While we still have gas to displace in summer it will make electricity cheaper.

I think $8/MWh is still not cheap enough for e-petrol. You can definitely do a lot of commodity chemicals for that price though with feasible carbon pricing. The tech is not ready yet but if the electricity is there then the tech won't be too far behind.

It helps in the short and medium term because solar is still the cheapest form of electricity that we have. Longer term we may lose some energy intensive industry (lol) if it migrated to sunnier climes because offshore wind doesn't get any cheaper.
paulboldrin.bsky.social
They don't even have to be that close - the price for solar in the auction last year was over 50% more expensive than this.

At least there's genuine progress being made on renewables and one global superpower seems onboard. The EU needs to link up with China to make sure there's no benefits to backsliding.

Wasn't the main problem that she spent weeks ignoring experts saying "uh, these gas price increases are really going to be quite big" by saying that tax cuts were the free market solution, only to do a last minute badly planned bail out AND still do the tax cuts?

An important (global) public service announcement from Ed Miliband on the day that renewables have over taken coal as the largest source of electricity.

So the Biden administration wants you to think that this is driving a green growth "miracle". Rather than.... (1/3).

This paper fits very well with the graph below in explaining why Biden lost the election. The economic improvements during his tenure were mostly due to increased oil and gas production, and most of that money went to rich people.

The prices are crazy - it's just under £100 for me and my two kids if I wanted to go to the Copenhagen game which coupled with the nightmare of getting home (an hour on a bus to Ally Pally) makes it not very appealing as a midweek proposition.

Can't believe they've given a Nobel prize for MOFs and overlooked my contribution of <checks notes> one paper on MOFs. Suspect it might be the closest I get to a Nobel prize!

Fun fact - you can actually just look election results up on the Internet. The Tories have *never* got lower than 10% in Scottish elections before or after devolution. They got 19.4% in 1988 under Thatcher!
paulboldrin.bsky.social
The Tories got 20% in the 2022 elections and 25% in 2017.

This is a very interesting article and interview, keep fighting the good fight, I think you're doing a great job.

He said "in the long run" not "in the latest opinion poll".

Maybe read the article?!
