Versus a cost in London of £2.50 per cubic metre or $3.40. I find this extraordinary

I see that Hannah Daly concurs with your numbers so that’s about 4c cubic metre

I don’t follow the maths .. if it takes 3KWh to make a cubic metre and it costs say $1.3 cents per kWh surely it would cost 1.3x3 or 3.9c cubic metre not $0.30 cubic metre ? Or did you mean 30Kwh per cubic metre ?

This of course is a feature not a bug of open markets

I think a big reason prices are so low in SA is that, while the costs of solar and BESS are falling yearly, Chinese manufacturers are also just undercutting everyone else in open/no tariff markets—see the two SA BESS systems that were priced at ~72/kWh: www.linkedin.com/posts/mlkubi...

At these levels we are within the envelope in which SA can have plentiful supplies of water from desalination at v low prices and it can probably manufacture synthetic (and renewable) fuels that can store energy for use in other areas at prices that are lower than the cost of oil or gas today.

Just take a look at the prices at which these deals cleared.. these are obviously for intermittent solar (without batteries) but all the same they represent interesting benchmarks for public procurement of solar power in sunny places

Isn’t the problem that trees sequester carbon only for a period - as long as they live, after which the carbon is released back into the environment as they decay. The conditions under which the coal, oil and gas reserves were laid down in the distant past no longer exist.

It’s a theory of course. But it’s plausible because the market is a discounting mechanism and long term costs of climate change translate into short term costs for corporates and societies through among other things the insurance markets.

This isn’t just a US issue but the US housing market is a huge cog in the wheels of global financial stability.

“If insurance is no longer available, other financial services become unavailable too,” he wrote in a LinkedIn post... “The economic value of entire regions — coastal, arid, wildfire-prone — will begin to vanish from financial ledgers,” he added. “Markets will reprice, rapidly and brutally.”
