As nice as it would be, a not insignificant amount of coal being transported is destined to steel production. Steel is iron + carbon, and the easiest source of carbon is coal. Steel is pretty important, so that’s not going away anytime soon. I wonder if carbon capture could make a product that could be used to replace coal here though, and fairly effectively sequester the carbon in an actually useful form?

What biomass grows the fastest without being waterlogged - I imagine bamboo or sugarcane or something

Grow that, and burn it to make carbon neutral steel; bonus points if you do it in a highrise/underground farm but frankly some medium term reversible environmental damage is preferable to killing off way more with climate change

Eh, purity is a thing. Biomass is the opposite of what you want there, but it could be doable. I do wager, however, that the largest “climate cost” of steel comes from the repeated melting of the steel.

Coal has a bunch of impurities compared to charcoal I thought?

And if the repeated melting is done by burning biomass/charcoal or with clean(er) energy then it’s not a huge issue

There are efforts to develop green steel, it’ll be more expensive than coal, but coal is only so cheap because of the huge amount mined for fuel
