New breakthrough claims 90% reduction in Steelmaking emissions.

Steel making accounts for about 8% of all global emissions, and that's rising quickly as urbanisation accelerates around the world. So we need to decarbonise the steelmaking process NOW! Here's a great new solution for how to achieve that goal.

One of your best videos, because you listened to the people in your Patreon community who understand the issues better than even the researchers who wrote the paper you were commenting on. Rather than just putting the hyperbolic statements of the researchers out there and letting commenters challenge them, you actually listened and put the necessary context in there for the viewing public. That is fantastic- keep up the good work!

I have absolutely nothing worthwhile to add to the content of this video, but THANK YOU for your tireless work! And your honesty and integrity.

[bobbresnahan]

Thanks again. You're bridging the gap between the scientific/engineering community and the environmentally concerned groups that I'm part of. There is a way of thinking about these problems that allows people from my milieu to actually contribute. You help.

[turkeytrac]

This is what I love about your channel, the non confrontational exchange of information and experience. Very refreshing, and as some who has retired from building huge oilsands projects, helps me get into all the great ideas put forward without getting my hackles up! Well done! Carry on!

[lestermarshall]

That's what I like about this channel. Check, re-check, correct errors, re-check and be open minded enough to accept new information that changes the story. Great Job Dave. 👍🤠

[Dr.Gehrig]

I'm glad you're spending more time on decarbonizing steel. Two technologies I'm sure we would love you to cover and update are Molten Oxide Electrolysis (MOE) initially discussed by Engineering with Rosie and Lillacs Direct Carbon capture (for cement) as discussed by Simon Clark.

[matthewsaxe]

I appreciate this dynamic of adding Information with crowd access. Brilliant.

[martynpost]

Hat tip to your patreon suporters. I work in steel industry decarbonisation. We saw this paper and was angry at it's conclusions for same reasons in the video and the basis being theoretical. Sadly other press sources don't give the same scrutiny! Thank you

[santoshlimaye]

As all the commentators have said in various ways, it is rare to see this level of integrity on YouTube technology videos. Great work in motivating people to think differently through “just have a think - -“

[nik_cage]

I love this channel a lot for staying informed about the global efforts for carbon dioxide reduction. It can be a bit of a pick-me-up to hear of all the minds hard at work in the area, but also a bit of a downer to really and fully grasp the immense scale of the issues.

[johndagle]

Excellent installment as always. Your introduction of alternative views and information is so refreshing compared to the many click bate focus of headlines that often are a quantum leap from the body of the text. You are truly prompting us to have a think about some data collection rather than stating it as conclusive reality. So often Correlation is presented as causation when a little think will help to see alternatives that are often times far more viable explanations! Keep it up.

I do hope the Birmingham team get some traction with the local UK steel production teams, perhaps to explore what it would look like to setup their new process in the current steel production lines. I worked as a sponsored undergraduate student for British Steel back in 1978-1981 and having lived in Newport was highly connected to steel production as were almost everyone in my street as Llanwern Steel plant was a huge local employer. It would be good to see the research team in Birmingham help the local steel producers. Thanks for presenting these low carbon ideas Dave.👍

[williamarmstrong]

Well that proves quailty youtubers attract quality watchers. I am humbled to find myself in such company! Keep up the good work and keep smiling!

[paulbennett]

This is the only channel I trust. There's too many sites giving out information that sounds either too good or too bad to be true

[confuzzius]

Yes, the moment you mentioned CO replacing Coke, my Pyrometallurgist training (I cut my teeth on Blast Furnaces) dug in heels (burden properties are crucial!). Could be interesting (and easier) to apply this to DRI or HBI processes, which are gas based. But for BF, not likely.

5:20 "[FYI; I don't know anything about this next bit, I'm just reading it]". 👍
-- This is the sound an educated man makes when he doesn't need his ego fluffed. And yet another reason these videos have trusted value.

[masish]

Hey, good catch and so glad you corrected it. I appreciate your insight and sharing of these new technologies.

[digiryde]

The company I work for is highly dependent on high strength carbon steel. I have been watching these developments with great curiosity.

Thank you for covering.

Texas has some 20, 000 wind turbines spinning and likely an equal amount of electricity from solar farms, so if there's an All-American corridor for developing hydrogen-reduction electric-arc steel production, that's the place. With Iron Range taconite shipped through the Illinois Waterway, down the Mississippi, and via the Intracoastal Waterway, Houston could be the steelmaking capitol of the world.

[richardcooper]

Happy that your Patreon pointed that out - saves me the effort. Those coke pillars also allow iron and slag to be tapped safely and the taphole clays used wouldn't work without them.
