Michael (and Chris) I've also been analysing curtailment recently, and can confirm that it's disastrously high. The most frustrating aspect is that we're still burning GW of gas because the curtailment is due to lack of grid more than lack of demand. See my work on eldwick dot org dot uk.
r.e. your questions on storage needs, on my site (menu -> grid storage -> detailed simulation model) I have a model using actual hourly figures from 2017 to today. Have a play with it, but I find that 400GWh of lithium type storage gets us near to 95% renewables. (Low efficiency storage like hydrogen needs more, as well as more generating capacity)
Agree. Sadly BASF don't give much technical info on their press release. I'd like to know what phase change fluid they're going to use.
Normally you can recover waste heat and use it to preheat ingredients with heat exchangers (in the 1980s I designed them for a few years) The issue is normally cost of capital goods verses cheap energy.
That storage requirement is very large do GB energy know of it?
Can it be done?
Which method will play the major role?

Heat pumps for chemical plants - I learned about the possibility of this in my first year of chemical engineering at Manchester Uni in 1980. At last !

This could be important
