The union welcomed Thyssenkrupp’s commitment to replace two of its blast furnaces with a direct reduction plant, which in the future will enable the company to produce less carbon-intensive steel using hydrogen.

Here's the fun thing about bulk hydrogen: it's produced using a process called "methane steam reforming". Anyone who tells you that they'll get the bulk hydrogen from electrolysis is either a fossil fuel agent, or an ignoramus who's listening to fossil fuel agents.

First, it releases ridiculous amounts of CO2 into the atmosphere.

Second, it uses methane as a feedstock.

Where will your methane come from, Germany?

For anyone who would like to learn more: Look up Green, Grey, Blue and black hydrogen. (Green is a scam, grey is made from gas so is blue and black is from coal. It's all awful.)

It was like only two years ago when LKAB, seemingly completely seriously, talked a bunch about how their steel production would be 100% fossil free in the near future. Their furnaces were to use about half of the electricity in Sweden. I think they gave up on that plan.
