  1. Steel is one of the most popular industrial materials in the world, with more than 2 billion tons produced annually. This abundance, however, comes at a steep price for the environment.

    Steelmaking accounts for 7 to 11 percent of global greenhouse-gas emissions, making it one of the largest industrial sources of atmospheric pollution. And because production could rise by a third by 2050, this environmental burden could grow.

    More recently a team of researchers have created an innovative manufacturing method that will dramatically reshape the way the alloy has been made for centuries. By using electricity to separate iron from its ore, the firm claims it can make steel without releasing carbon dioxide, offering a path to cleaning up one of the world’s worst industries for greenhouse gas emissions.

  2. Basically to create steel you need heat. Traditionally this heat comes from burning carbon so let’s find a way to create heat without carbon. Essentially the basic problem statement for all of mankind

  3. I have friends working in this area with h2greensteel which had recently gained huge investment, I’m very interested to see just how far they’re able to push it, though if they do it almost makes me want to join such an important industry too

  4. The U.S. steel companies are actually investing heavily already in green production and based on this article are already further ahead in implementing green steel processes in their existing and new mills.

    New energy technology is cheaper, cleaner, cost stable, and safer than using fossil fuels now. It’s a no brainer for business.

  5. For all the discussion on using hydrogen vs. electricity for primary steel production, one key thing will be to use ‘excess’ energy it will be economicaly critical to separate the variable energy part from the Capitol intensive part of the process. For this aspect hydrogen is much more storable as an intermediary than electricity.
    Even if the process is technically capable of ramping, such a high Capitol process as steel making will not be economically capable of ramping outside very limited crunch situations. The long and short is direct electrical reduction will need dedicated electrical supply, and this needs to be accounted for in the overall cost.

  6. Is it economical & will it scale?

    “Another barrier is cost. Switching to electricity or hydrogen would require vast amounts of capital spending to erect new plants and retrofit old ones.”

  7. Seems like an intriguing/promising investment to get into. What companies are leading the green steel race?

  8. Naturally occurring veins of green-flecked iron run through the rocks in some of the Nine Hells. Called ‘arjale’ in the fiendish tongue, it occurs nowhere else. When refined it is a lightweight, black metal which can hold an edge, but when alloyed with iron, it becomes the light green-grey metal known as ‘dajavva’; green steel.

    Darjavva is lighter than normal steel, and can be honed to a razor-fine edge, making green steel weapons both faster and more deadly than their normal counterparts. Green steel weapons have a natural +1 bonus to attack and damage rolls, and are considered magical for overcoming the damage resistance of celestials and fiends.

  9. It’s using electricity so… Mu question now is how the electricity will get produced for this process 😁😁😁😁

  10. Who cares what color the steel is, you can’t see it from the outside of the building anyway

  11. Sweden just approved the first steelworks to be built since the steel crisis. That’s going to be the first in Eutope in 50 years, something that was once a major industry in Sweden. I think the company is H2 Green Steel, they’re going to build it in Boden.

  12. How about we start producing and consuming less, across all sectors and industries. That would put a big dent in emissions

  13. How ridiculous to recenter an industry on the color green. 2.5 Trillion!! I think paint makes this resolution moot. Why focus on turning all steal green?? And they could at least choose a cooler color like burgundy or neon.

  14. Using electricity to separate iron from ore is… interesting. I know you can do that for scrap metals but I thought electricity won’t be able to reduce the iron oxides into pure iron for steel.

  15. This isn’t green.

    This is greenwashing.

    All of the power to generate this will come from natural gas to produce the hydrogen.

    This is terrible for the environment! Look it up yourself!

  16. Oh, so now we can’t have steel either. Yeah, very realistic. We will just get rid of cars, beef, STEEL, electricity that works and everything else. But we will save the planet… from the sun monster. Go Green New Deal go Captain Planet!

    Our world is in peril. Gaia, the spirit of the Earth, can no longer stand the terrible destruction plaguing our planet. She gives five magic rings to five special young people. From Africa, Kwame with the power of earth. From the North America, Wheeler with the power of fire. From the Soviet Union, Linka with the power of wind. From Asia, Gi with the power of water and from South America, Ma-Ti with the power of heart. With the five powers combined they summon earth’s greatest champion – CAPTAIN PLANET!

  17. As with all of the Climate change/Green Energy bullshit, It is simple a well run and well funded scam. There are more holes in the above story that in a sponge.

    1) Greenhouse gas does not exist. It is a term concocted the radical left wing Lunatic Al Gore. He has been predicting climate change since the 1960’s and NOT ONE of them has come true. He is simply a lying snake oil salesman.

    2) Without carbon dioxide and photosynthesis there would be no oxygen. Without oxygen, we will die. Short of an all out Nuclear War, man has no affect on the enviroment.

    3) The processes touted in this article require massive amount of electricity to operate. The source of this electricity is either coal, natural gas, oil or nuclear. ALL OF WHICH THE CLIMATE LUNATICS HATE, BUT CONTINUE TO USE!

    4) Iron ore has a melting point of 2,880 degrees. Aluminum ore melts at 1,220 degrees. It would take 200,000 acres of solar panels, producing at there maximum capacity, to achieve the temp needed to smelt Aluminum and twice that about for steel, in just one oven! In addition, these panels would have to work at maximum capacity every day and would be worthless on cloudy days and at night.

    5) Practically speaking, the green lunatics know and understand that they cannot produce what they tell you in there conferences and publish in their papers. It is all a fallacy. Don’t believe them because the technology needed to accomplish the items listed in this article are at least 100 years away.
