The world’s first customer delivery of “green steel” produced without using coal is taking place in Sweden, according to its manufacturer.

The Swedish venture Hybrit said it was delivering the steel to truck-maker Volvo AB as a trial run before full commercial production in 2026. Volvo has said it will start production in 2021 of prototype vehicles and components from the green steel.

Steel production using coal accounts for around 8% of global greenhouse gas emissions. Hybrit started test operations at its pilot plant for green free steel in Lulea, northern Sweden, a year ago. It aims to replace coking coal, traditionally needed for ore-based steel making, with renewable electricity and hydrogen. Hydrogen is a key part of the EU’s plan to reach net zero greenhouse gas emissions by 2050.

Jolly good, carry on.

I didnt read it but I don’t think anyone else did either.

Using giant lasers to annihilate a speck of hydrogen, scientists at the U.S. National Ignition Facility came close to reproducing the sun’s power. The experiment spurred optimism for researchers’ hope that fusion could be a boundless, clean energy source.

I fear that sibeen may have read that, and is yet to recover.

Or it will be when there is sufficient “green hydrogen” to supply this and other needs.

We could also use Syngas (carbon monoxide and hydrogen) to make direct reduced iron. This could be obtained from biomass.

I’d love to build a test plant solar thermal collector which could be use to heat biomass to pyrolysis temperatures, with the volatile gases (CO, H2 and others) being collected and separated out. Normal pyrolysis processes use the gas as the fuel source for the production of char, but why not use solar thermal and produce two useful products.

There’s been plenty of steel made without (much) coal for 50 years. It’s called recycled steel.
But I take it that that’s not what they mean.
To make steel from iron ore without coal you’d need soumething else to react with the oxygen.

Iron production from ore usually requires more coal than iron ore.

You could use natural gas.

> SSAB has now produced the world’s first fossil-free steel and delivered it to a customer. The trial delivery is an important step on the way to a completely fossil-free value chain for iron- and steelmaking and a milestone in the HYBRIT partnership between SSAB, LKAB and Vattenfall.

> In June 2021, the three companies were able to showcase the world’s first hydrogen-reduced sponge iron produced at HYBRIT’s pilot plant in Luleå. This first sponge iron has since been used to produce the first steel.

> We’ll be converting to electric arc furnace in Oxelösund as early as 2025.

One quarter of the world’s steel is already produced by the electric arc method. The sponge iron would just go in as another piece of scrap iron.

The key new aspect here is getting sponge iron using hydrogen. Where do they get their hydrogen from now?

I’m generally very cynical about attempts to make iron from iron ore without coal, but I think this has promise, if the cost can be kept down.

Or if the cost of using coal is raised to recognise the future costs associated with the emissions.
