There was a recent Infinite Monkey Cage about cooking that touched on this. https://www.bbc.co.uk/sounds/play/m000rtyyshpalman wrote: ↑Fri Feb 12, 2021 7:05 pmI vaguely remember there being something on No Such Thing As A Fish (would have been an episode from about a year ago) about spoons made of different metals contributing to the taste of the food.

Some people call me strange.
I prefer unconventional.
But I'm willing to compromise and accept eccentric.

having that swing is a necessary but not sufficient condition for it meaning a thing

Re: Coal
I realize that. But we need coal to make it, until we figure out a better process. So in the interim we should limit its useGrumble wrote: ↑Fri Feb 12, 2021 8:26 pmSteel isn’t inherently fossil fuel derived as my first post in this thread shows.

Re: Coal
I think the point is that there are processes that don't need coal - in that the iron ores can be reduced via Hydrogen, the energy can be provided via electricity, and the carbon can be biochar etc.Herainestold wrote: ↑Fri Feb 12, 2021 10:44 pmI realize that.

It's just that the use of coal - or metcoal - works on an 'it'll do more than one bits of that' basis.
My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!

Re: Coal
The production of steel is one of the most optimised industrial processes in the world. That's because everyone has been trying to produce better processes for the last ~200 years and even small percentage increases in optimising the process can produce massive economic benefits. The British steel industry almost died because they concentrated on production (and short term gain) while other steel making countries (especially, IIRC, Japan, USA, Italy, Brazil) stayed innovating and could then undercut British steel.Herainestold wrote: ↑Fri Feb 12, 2021 10:44 pmI realize that.

Re: Coal
Thyssunkrup are ahead of the game and have been actively experimenting with using H2 in steel making since 2019. They fitted out a blast furnace with a H2 feed and could make steel with it. Scaling up and cost issues still need to be resolved, but their press releases are full of bumpf about securing H2 supplies.
