Love your videos but Kamikoto knives is a scam. It is one company of "fail ventures" (not kidding, that is their real name) who has other scam companies like established titles and deal dash. Knives are produced in China without Japanese steal and since the mother company have failed 70 times out of 74 attempt to create companies, the life long guarantee is probably as guaranteed as the Line being constructed;-).
Not to mention that the steel the knives are made out of is most definitely not "green" and carbon-free, I would assume.
It's also really bad steel that doesn't hold an edge as well as even a cheap supermarket knife. See Shadiversity's video from about 6 months ago for details.
Went looking for this comment. The irony of a kamikoto sponsorship on a video about actual 'green' carbon steel is something else.
I wonder how many youtubers 🥔 have a set of knives rather than a skeleton in their closets. lol.
@@File001 is it even steel?
Please do due diligence on your sponsors. Kamikoto is at least dishonest (not Japanese) or at worst an outright scam!
yeah that kind of ruined the whole video for me
also i suppose it is not using green steel 0_0
i would say is dishonest because at least they send you the knives, with that being said they aren't japanese registered entity nor they're made in Japan
@@ristekostadinov2820 their corporate address for a while was literally a hotel room in Japan until someone figured it out then they changed it to their real address in Hong Kong
Shadiversity channel made a video on those knives since he had thinks it as a scam product. he even shows how bad quality they are, so nothing high quality or even Japanese about them.
also its the same people behind ''Established Titles'' which right now is being called out as a scam as well.
its a great video, really got the sustainability brain in me hyped, but got ruined by the Kamikoto sponsor.
Racon headphones are a scam as well, over the last few days I've seen lots of posts about all these scam artists on RUclips channels, that's why I love DankPods because he refuses to use any of them and just uses Patreon to fund his channel.
Don't bother getting hyped, the steel is much more than iron+carbon, you need chromium, molybdenum & nickel to make steel. And Chromium is transported on diesel driven giant cargo ships from China. And then you have to factor in trains driven by diesel in order to transport the ore to the ports.
Then you have to ask yourself, just how many windmills does SSAB use to fuel their steel mills? Nah, they're placed next to hydroplants which the green party is slowly but steadily dismantling.
There is 0 "sustainability" about this, it's a scam. It's just a meaningless hype word. It's like a magician telling you to only look at his right hand and disregard what his left hand is doing.
Wait a moment, Fred Mills runs tomorrows build AND the B1M?
This explains so much
I was taken aback for a sec, but same
He might also be the Terminator @1:00
Scroll right to the bottom page of the channel home page - also has Build in Brief 🤣
This gives wendover productions and half as interesting vibes
Wait until you discover that he's been doing this for around a decade. There is a long road of hard work behind every successful RUclipsr, they may appear to come out of nowhere but they don't.
I know from my professor, that the german companies like SalzgitterSteel are currently trying to implement this production technique for their production. The even plan on building windgenerators on the facillityground to produce the hydrogen.
In General, the concept of "green-steel" is nothing new. ThyssenKrupp is currently trying to convert their furnaces to accept gas, such that they can be easily switched to Hydrogen later on.
So no. Sweden has not discovered "green-steel".
@@Ruhrpottpatriot well no one else has made green steel before, as gas furnaces do still have massive co2 emissions.
Your basis is the person who jumped basicly flew for the first time and solved flight.
Achieving and theoretically trying are vastly different.
In this endeavor Sweden was first.
@@fridaybot No, the title of this video was "Has Sweden invented green steel".
The usage of a know practice is not "inventing", it's "implementing".
And then even that is false. The Deutsche Edelstahlwerke already has a production method in place with reduced CO2 emissions by 90%, the swedes have 95%.
@@Ruhrpottpatriot H2S replaces a blast furnace by directly reducing iron ore (historically done with coke to make pig iron or natural gas to make direct reduced iron). You currently cannot make all grades of steel from scrap in an electric arc furnace (EAF) like at Deutsche Edelstahlwerke (a scrap melter/mini-mill when compared to the integrated mill in video). The breakthrough is reducing iron ore with hydrogen, not burning it for heat in a furnace like at Saltzgitter (mills have lots of furnaces from melting to post cold rolling)
@@trail-coffee4654 So exactly what TK wants to do starting 2024, i.e. 6 years prior to the plant from H2 Green Steel?
To quote TK: "thyssenkrupp Steel targets to put the first DR-plant into operation on an industrial scale in 2024."
Currently TK runs a H2 electrolysis plant in a venture with STEAG with 500MW capaity. This H2 will be used for DRI.
Also TK isn't building a completely new plant from scratch, like H2GreenSteel, but refitting running furnaces, which has additional complications.
It’s stuff like this that makes me proud of being a Swede.
Me too
Its stuff like this that makes me proud of being an aang-anng
Sweden is a great nation
Dont let the modern media tell you otherwise
We do this everyday in northern italy... Smh
But you did nothing.
I love the subtitle "Images not indicative of Fred's cooking ability " - the rest of the video is also great and good to hear about new solutions to big problems.
Every country needs a good first-world solutionist
Denmark is still better ;D
Finally someone has a sponsor that isn’t a vpn.
Update: after research, shame the knives are fake.
This is worse, they are Chinese company claiming to be Japanese. It's the same company as established titles, about being a lord. Disappointing they are promoting this scam.
@@74_pelicansnice find. I live near Tokyo and they post 2 different addresses on their website (probably misspelled) and one of them (in Japanese) is a showroom above a convenience store. But that place is empty. The other location (English one) is also fake with 5 star reviews made by foreigners and only one Japanese guy calling them out as fake. 🤛
Actually there are plenty of steelmakers in Europe discussing/planning to use the HDR-method. There are also some initiatives in Germany for example to modernise entire industrial regions by focusing on using hydrogen instead of fossil fuels. Its really interesting to see what synergy effects are possible when you connect different industries (from byproducts that can be used somewhere else to redirecting process heat). Only downside atm is the cost of green hydrogen (production as well as transportation and storage) and the lack of proper subsidies from governments. Hydrogen imo is really being held back by the "let's electrify everything" agenda. But let's see where we are in 5 years
And governments don't know where to spend those green euro's effectively. Making car manufactures spend billions on R&D to make diesels 1% cleaner. While the steel industry is pumping out CO2. And also offshoring manufacturing has also not helped reducing global emissions.
Carbon free steel can be accomplished through molten oxide electrolysis which is far cheaper and less energy intensive than hydrogen. I don't see hydrogen winning this race personally
I totally agree
A lot more investment in R&D to bring the cost down and especially find materials that are cheaper to make electrolyzer more cost efficient
The energy solutions to produce GH2 cheaply are available, it’s just the equipment to convert and then the best solution to store/transport ( which might be ammonia)
Solve for electrolyzer membranes and we are well on our way
SVERIGE! Sweden doesn’t disappoint ❤

@@topi2209 Finland still angry because you belonged to Sweden for many hundreds of years :D Always finns writing this cringe comment online...
@@topi2209 Silly east-swedish person.
Yes it does, am from Sweden and the plebs voted for MP which is a "green" party who forced nuclear plants to close down in our country which has now lead to the energy prices being so high that this green steel is NOT going to be produce since it requires 3 times more energy. The fact that ppl said no to nuclear plants during the 2000s just shows that ppl dont even spend 30 min on reading up on the subject themselves.
Same goes for Germany the green party ruled for 8 years and closed waaaaaaay too many nuclear plants before they even were close to replace any of that energy and the result was that our government owned company "Vattenfall" shipped coal from fucking across the atlantic ocean, like srsly damn retards
Sweden always disappoints, and there's no such thing as fossil free steel. Steel needs carbon else it ain't steel. And we haven't found a way to source carbon cheaply that isn't from Coal Deposits and Coal Deposits are all Fossil Fuel.
As a Norwegian, i'm proud of my söta bror Sverige
If this holds up it could indirectly help part of the storage issues with something like wind energy. Conversion from energy to hydrogen and back again isn't super efficient but if all you need is the hydrogen for this process, that could be produced when there's a surplus of energy in the grid, instead of shutting down wind turbines to avoid blowing out the grid.
It obviously won't help with getting power back into the grid on demand but taking care of surplus in the production line of a highly needed product will presumable make it possible to put up more windmills without having to shut most of them down outside of peak consumption hours.
The HYBRIT plant is going to use more electricity than the entire country of Finland if ever built out according to the plan. Swedens already high energy prices are really going to soar.
To make this a reality we are going to have to invest heavily in stable green energy like nuclear power.
They already have, it requires two nuclear power stations to make the Hydrogen. India has been using hydrogen on a small scale for years
I live in Luleå! There are so many things going on in the north of Sweden it's crazy!
Sweden is investing 50 billion dollars to make all its iron ore into green steel. 30 million tonnes of green steel. It will take 70 TWh of power every year to produce all the green hydrogen needed, double the amount the country of Denmark use every year in total.
And what a coincidence that Sweden also happens to have one of the world's largest >67% Fe magnetite deposits.
And in 2021 Sweden exported 166 TWh of energy. Meaning that this increase in energy use eats up about half of the exports. Since it is based on hydrogen it doesn't really matter that production can mostly be done when the wind is strong.
@@newperspective5918I totally agree
And furthermore, that 166 TWh of export can still be a sustainable revenue stream for the govt because they can simply increase their wind energy production, that’s a beauty of such renewables, it’s renewable
The 2021 production can be increased 👍🏾

Proud being a SSAB employee and a Luleå resident :)
Is this hydrogen they are using now even actually fossil-free? To make green H2 from purely renewable power is still 5x more expensive than gas based H2 and very rare, making any resulting steel product a very expensive and undesirable deal. I can't find anything about the source for the "fossil-free" electricity on their website either.
I think Fortescue is going to be the supplier.
Certain people get somewhat annoyed if you bring the topic of “cost” into the discussion. Apparently their motto is “at ANY cost”
Almost all of Sweden's electricity is green. 90% is from hydro, nuclear and wind. Less than 1% of Sweden's electricity was produced from fossil fuels in 2020.
Can Sweden produce enough steel to be a major exporter in the world market? Can they compete with giants China & India?
@@Tux.Penguin probably not. still, if they manage to perfect this technology and bring the costs down, bigger producers will follow
absolutely brilliant
So at what point does the reduced Fe acquire the Carbon atoms to become actual steel. My understanding was that the steel we use is an alloy of carbon and iron molecules with some additive elements for specific use cases. If all you add to the steel is hydrogen to reduce it, there is never any steel made, just some high purity iron.
Seeing the plant,it seems, it will take another 30 years before we mostly greened this industry. Nevertheless, Thyssen does the same thing in Germany, would be a real different, if we get it through Europe quickly. With Ukraine have to rebuild it's industry maybe next year, it would be a good starting point. Really hope and assume in the US is similar progress made.
The EU will lead the way ,far ahead of north America or Asia
Kinda funny that they are planning on using renewables while Switzerland is considering banning electric cars because their grid can't keep up currently.
The first work on this process began way back in the 1950's. Brazil was hoping to create a domestic steel industry but while having abundant iron ore deposits there was little coal to turn into coke.
Thank you
I remember hearing about that.....
Brazil has a good future ahead if they work a few things out

Hi Fred,
I was hoping your video might address one of the downfalls of this method.
From what little i understand this process requires high Fe iron ore. Eg. Australia produces some of the highest grade Fe at 65%.
This process cant handle low grade ore and thats a lot what the rest of the world uses.
Swedish LKAB iron ore grade fe is at 67 percent
Interesting. Is this fundamental, or just because it is new and they pick the easiest problems to tackle first?
They are opening up a green steel factory near my town and I was intrigued. Now I know more about it and why it is getting so much attention.
However, I did drive to the location of where they are building this huge factory. They chopped down basically an entire forest, and the factory requires more accomodation and the such in order to host its staff in an already cramped city. It just feels off claiming it's fossil free and etc when the entire process, from start to finish isn't by any means this.
Australian company Fortescue is doing the same thing
The sponsor makes a sharp decision by slicing their time into such a foundational video, they are sure to steal a chunk of the market.
dude your puns make a gradient, what the ⨌
"Steel" was just there, and you missed it... 😂
Except the kamikoto is a scam and really disappointing b1m brand aligns with them.
They are scumbags
Truly cutting edge technology. But I feel the world is still on the knife-edge in regards to the steel industry. As for the Kamikoto knives, well, it is clear-cut that the Japanese make great knives and Kimkoto's stab at crafting blades is no exception.
They just made what I thought of.
Idea vs money.
Love your channel, just please stir away from scamming sponsors like Kamikoto or established titles…
The irony of the fossil free steel prototype being used on a mining truck.
You keep on surprising me Mr. Mills! My birthtown (Luleå) shown on Tomorrows Build! Fantastic!

@@Mr_Cool Nä man önskar att alle i norr om Markaryd, Småland, skulle käkat lite mer flugsvamp per år, särskilt om ni tror på det här med Fossilfritt stål. Vart får de kolet från?
Senast jag kollade så är inte vätgas kol, och oavsett om de använder vätgas för att rena järnmalm från oxider, så betyder inte det att stålet är fossilfritt, kolet måste tillkomma på ett eller annat sätt, och senast jag kollade så finns det inte tillräckligt många träd eller Koldioxid i luften för att man skall kunna utnyttja entendera för att tillverka kol på någon långsiktig tid.
Oh my god, the sponsor video was EVERYTHING lol
if i had a dollar for all the knife puns in this...
You’d be rich
TB: Come for the construction insight, stay to see Fred's slicing culinary chops.
To all of you commenting on him not responding to the fact that it is a scam. It might well be that he knows and don't care, or he didn't know beforehand but doesn't care after finding it out. However, there is a possibility that he didn't know beforehand and now that he does he risks breaching his contract if he were to acknowledge or recant his support for them.
I have a couple of questions. How much does that steel cost to make. And, was the energy used to make it completely from renewables or was it from renewables only during daylight hours? Did they use battery capacity when the wind stopped blowing and the sun stopped shining? Sorry, I'm just a little sceptical.
The price is supposed to be comparable to regular steel when everything is completed. They will use hydropower from Luleå river
Look up Swedens energy production. A lot is produced up north in hydropower in massive amounts. In 2021 Sweden exported 166 TWh of green energy. For other countries, yes I agree, but for Sweden, not so much. It is an international powerhouse when it comes to green energy, especially up north.
I caught a shot of PDX...nice. Didn't expect that to show up, had to stop and slow it down to take a better look.
What is this ad Fred lmao
Promoting a scam, really disappointing by the b1m team.
The main issue with that is it's cost compared to traditional production, if it's way mor expensive Chinese cheap steel will just flood the market. Also how does this production method work at larger production scale, is it even possible? Will it require absurd amount of electricity with additional production size?
Main issue short term is that hydrogen isn't green... yet
@@Garner84 If anyone has the resources to produce green Hydrogen, then it's got to be the Nordic countries with all that hydro power &c.
I wouldnt be surprised if the EU would be willing to subsidise the higher production cost so the chinese stuff cant compete
Why not just make a certification for co2 neutral steel and ban all products that don't adhere to it, super easy regalatory wise. All responsibility rests on the manufacturers/importers who don't want huge fines coming their way. If the goverment judges there to be to much disregardment of the policy they can just instruct the police to put more of their attention into regalatory work.
@@JP_TaVeryMuch actually, Canada has a fair amount of slack hydropower capacity in some areas and about 100% room for expansion, ie could feasibly at least double their hydropower production.
More than half of steel is made from recycled scrap which can be done by induction ovens - run on green energy but vastly more efficient than extracting from ore - without the use of green H2, you fail to mention that.
I'm not putting down green steel btw, It makes total sense to do that up north where there's an abundance of green hydro.
Please do concrete next and how to make it green (or replace it for something more sustainable by mid century).
Good points, especially about the recycled steel using induction
But regarding concrete, this is well underway
In fact very very close, for example instead of using GH2 for the process like this one he covered, they also produce green steel using electric arc furnace, (which might be better than using GH2),
AND similarly they also have electric kiln furnace for cement, so the removal of coal from the process is already accomplished and if they wanted to use CCS to capture the remaining 30-40% Co2 from the limestone conversion it is possible because the particulate matter isn’t an issue because it’s mostly Co2 alone (no coal used) and very little other contaminants 👍🏿
That makes CCS possible when it isn’t possible in the legacy method of cement production
There’s a US startup that has found a new way to create cement using a purely chemical reaction without any heat conversion, it’s early days and needs to be scaled to see at what cost it is possible
So, I’d give it 10-15yrs at most before these things (and others) are available commercially at scale
Proud to see my home town and my country at the center of this development! But to scale this up, we need a lot more electricity, from all clean sources - nuclear, wind, solar, fossil gas with co2 capture, hydrogen storage, biofuels, you name it.
The hydrogen based DRI process sounds encouraging, but still uses mined iron ore. We can already use 98% recycled steel in renewable powered micro-mills, to me this should be hilighted as technology we should be rewarding now
The absence of a pricing mention is a gigantical red flag.
It's an interesting concept, but I don't understand how they add the carbon to the steel, because, as I understand it, originally the iron ore is mixed with both limestone and coke in a blast furnace and you get molten pig iron, the carbon content of which is later lowered, instead of making it a 2-step process, separating the pure iron and presumably adding the carbon later, as is implied in the reaction formula at 2:38. Steel is made of iron and carbon, and, as far as I know, there isn't a feasible way of combining these 2 on a large scale without emitting a lot of CO2. On their website I also didn't find them talking about that step of the process anywhere, only about getting pure iron from iron ore.
Would love for someone smarter than me to explain this please :)
Hybrit is cool but there's a big problem looming - the massive electricity demand. It's currently estimated that the sustainable steel production will require similar amounts of electricity as the whole of Finland. This will also mean that the steel will be way more expensive than regular steel that's using coke to turn the ore into iron.
Electricity is easy to come by if people would stop being stuck in the 1700's. We've got wind, hydro, nuclear, and especially solar. People often forget that the average solar energy hitting earth every 10 minutes is more than what we produce every single year in total.
We have a few different projects like this in Australia. One is with a British billion Gupta in South Australia. The other two are in Western Australia. All are using Solar and Wind to create Hydrogen to produce steel. Gupta has already created green steel pellets from his iron ore mine
What's the cost difference to use this method? And how much energy does it take to make the hydrogen for the process?
Opex alone is multiple $100s per tonne more expensive. Capex is catastrophic. If it were in anyway close in cost, everyone would be doing it already.
@@gavwah That's what I figured
To be fair to the price... This is not even early adopter costs, this is prototype stage. A small plant for proof of concept and science.
It will take time for production of scale, combined with mechanics like carbon tax schemes to make this economically viable. But we need to start somewhere.
@@marcusalm7350 it's not a coincidence that Thyssenkrupp will switch their first BF off in favor of Natural Gas DRI in 2026 considering what the EU's plan is for their carbon tax.
Unless your grid averages less than 0.15 t CO2 eq / MWh, natural gas actually has lower emissions than hydrogen in this application.
Carbon is part of ecosystem. Trees need CO2 to give us O2.
How much will the company charge to allow other companies to use their process? How long have they been studying the emission from the plant? Where can we read the results?
Welcome to my Country 😊
Two small things that actually is a huge deal.
1) Where does the hydrogen come from? How is it made? How much energy does it take to make it? The Short clip there shows a flat land with windmills (2:25) but the company that makes it is SSAB which does NOT take electricity from windmills but hydropower. (hydropower plants that the green party is closing down by the way).
2) Modern steel is so much more than just Iron + Carbon. 10.5% is Chrome, then you add Nickel and Molybden to make rust proof steel. If you fail to add these three additional ingredients you get crap quality steel with low durability and high rust rate. Now we got 3 questions to answer here; where does the nickel come from? What about the Chrome? And who makes the molybden?
A side note here is that you need aluminium to reduce chromite to chrome. And chrome is dug up in (mostly) South africa, Zimbawe, India, Cuba & Kazakhstan. Yes there are a few chromium mines in Germany, Hungary, France, Norway & Sweden but nowhere near as big as the first 5, so we need to add the transportation (along with the actual mining here). (we can safely disregard aluminium here since it's more common than iron).
Molybdenum is mosty mined in China, then 2/3 of that in the US, then half of that in Chile, then half again in Peru & Mexico. Again transportation and working conditions need to be taken into consideration.
As for Nickel, well if you find iron, you've found nickel.
So we got a bending of truth here where steel is ONLY made from iron & carbon.
Then we totally disregard transporting raw materials from the other side of the globe, we disregard that some of these countries have no laws regarding ground pollution while mining, and we disregard that when it comes to one big producer of Molybdenum have VERY questionable work ethics and slave workers are quite common to drive down the prices in order to secure a bigger market share.
So yeah, how about that "sustainable" & "green" steel hmm? yeah. whops. It's not fossil-free steel, the mining equipment are fueled by diesel, the semi trailers carrying the ores to/from ports are fueled by diesel, trains in many of the listed countries above are either coal or diesel powered if trains are used instead of semi-trailers. The big cargo ships are diesel powered.
So where is the fossil-free steel? Are we just looking at the production phase? If so we're lying to ourselves in order to pat ourselves on the back and feel good. And if you think going green and becoming fossile free then you're a hypocrite.
My man was having too much fun with that add loool
A minute and a half embedded ad in a seven minute video? Impressive.
This is why Sweden is a very powerful economy despite it's puny size and population. They come up with the most amazing technologies for such a minor country.
Didn't know the steel industry produces 7% of global emissions... The entire aviation industry is responsible for 3%. That's crazy
Recycling is answer to lowering CO2..Steel is super easy to recycle and stuff we put in bridges,building is low grade steel so recycle more!
Now now, let's not toot the horns too quickly.
A minor change: "Carbon free steel" does NOT mean getting the ore out of the ground without emissions of CO2. That's just a plain lie.
Omitted information: Just how much electricity are we talking about when it comes to creating this "carbon free steel"?
Truth is, the theory used for this is not groundbreakingly new - HYBRIT did not exactly come up with it. It's not feasible due to the humongous amounts of energy needed to power the processes and chemical reactions.
As it needs a humongous amount of energy, "Renewables" is another plain lie. We're talking more energy only in steel production than the rest of northern Sweden uses combined, an estimated 70-100TWh.
Sweden's current electricity production and electrical grid cannot support this at a large scale, and if it was scaled up, it would probably be worse overall for both emissions and environmentally than just burning the coal to begin with.
NO! The estimated power need is 70 terawatt hours aka the entire energy need of Finland.
I actually watched the full knife promotional add.
Carbon-free steel was demonstrated in 2006 by Professor Donald Sadoway and team, using molten oxide electrolysis.
Production expected in 2026, same as this company. Sadoway's method doesn't need hydrogen, so it is more economically feasible at current prices. If their numbers are correct, it's cheaper than traditional production methods.
Hopefully both companies start producing in 2026 with no issues.
Thanks for this very interesting video. Take care of yourself.
The only problem is supplying enough electricity
Lol, that's not the only problem by a long shot.
If it doesn’t have carbon added to it where will it get the flexibility that makes steel so versatile?
Love the channel ! Amazing work.
If you think about it steel is truly the one material that is the foundation of our modern world, without it we have nothing.
Very cool process. My only hope it's that's it's cost competitive with fossil fuel steel. Otherwise it'll be an uphill battle.
Easy, tax anything that comes out of the ground. Companies will scramble to use wind, solar and others to substitute mined coal.
It's apparently expected to be 20-30% more expensive by the time it hits large scale production. My money is on molten oxide electrolysis instead
Still need loads of energy to get up to temperature. They eliminated the coke required for the steel but that's about it. You still have the same energy overhead for mining, transport, and production of the ore and material.
Sure, but the benefit is that you can build it around non fossil energi.
Where is the water coming from? What happens to the used water? Or can the same water be used repeatedly? Are we eliminating serious issues by creating new ones, whether these issues appear/reappear instantly or in the future?
The water comes from the combining of hydrogen and oxygen similar to the way a hydrogen fuel cell works. H20 is water two Hydrogens and one Oxygen combined. The water isn't being used its being created.
@@samon53 Thank you
It's more about us finding better ways of doing things.
One of our bigger iron ore mining magnate down here in Australia is constructing a full scale green hydrogen plant in Queensland, and at least one state government is committed to another facility of its own . Steel production is the logical next step for such a large ore miner as Australia is. I believe green steel is a very exciting space, soon to be a worldwide phenomenon.
Very interesting - hadn't heard about that. Of course they still need to excavate the raw material, that they use to make steel (well - I assume). So it is not based on renewable ressources like wood. But since it is so long lasting under the right circumstances and since it can be melted and reused for new steel, it is a relatively ok material. Even wood buildings, cannot be built entirely without steel, as they normally uses screws, brackets etc. to connect the wood structures.
“This video was made possible by sharp puns” ……. 🙄
Never thought a knife would sponsor a construction video but it steel makes sense on this vid 😮💨
It’s because their other scam just got busted so they’ve pivoted to pushing this scam. Look up “fail ventures” and established titles.
The knives are made in China.
Compare the cost to traditional steel making and you will realize that there are better investments to combat the co2 problem
Well, maybe not if you own a steel mill...
Electricity supply is the biggest concern right now. The figure often mentioned is 80 TWh a year. I really dont see how that kind of capacity is gonna be built in 5-10 years
Is this the b1m side channel or Kopy pasta komrad?
Answer: No, because hydrogen is literally just a very inefficient way of storing the feedstock energy used to produce it. Unless you are talking about nuclear fusion, which will probably involve deuterium and tritium for a while IF it ever works, hydrogen is not a source of energy, it is a product of other energy.
I feel that this is a little misleading, as this technology isn’t new, but more investments and ascending costs in the traditional way cause most of the initiatives that we are seeing today. Nevertheless that company project is amazing and totally in the right path, but there are others that are going in similar ways.
That water is never water again though, is it? I wasn't listening.
Puntastic video Fred!
Greatest ad ever
It all depends on wind and solar generation
Did not say if there is a price difference in making green steel
There are lots of time when we have excess renewable energy, lots of steel could be green if the energy market wasn't corrupt/governed beyond reason.
Where do they get the green hydrogen from? Electrolysis uses massive amounts of electricity. How is it generated?
There are so many E.U. funded programs which study this reaction. It's not just Sweden. And the problem is not solved yet and it's not an easy technological problem. I am working in one of those E.U. programs for the green steel as a scientist.
And for those who say carbonless aluminium. The production of aluminium was always carbonless. It is electrolytic to be specific.
But is it cheaper? Come on Fred!
Anyone else feel this video poses more questions than answers? How have the processes from extractions through to production of the steel been decarbonised? Saying that they use hydrogen for reduction really doesn't even scratch the surface. Also how cost competitive is this solution likely to be? The major reason for steels prevalence throughout the world is its unmatched cost effectiveness, obviously while this technique is being pioneered its going to be a lot more expensive, but when scaled will it be possible to be competitive with conventional steel? So many questions.
Didn't hear a word in there about where they get their hydrogen.
Thier process is an important step to green steal, but it's not able to expand until we have green hydrogen in any amount.
Wind, hydro and nuclear are the main energy sources
hydrogen have metal porosity problems especially in fracture dynamics
Two problems. 1. Steel is an alloy of iron AND carbon. No carbon, no steel. Where are they getting the carbon from to produce the steel?
2. How are they solving the problem of hydrogen embrittlement? This is where the steel absorbs hydrogen and becomes brittle like glass. This is why traditional blast furnaces do everything possible to keep hydrogen out of the mix.
0.04% Co2 in our atmosphere
No they haven't, since it would take 80TWh/ year to run the two plants needed. That's more electricity than the entire country of Finland use, or enough electricity to electrify every car and truck in Sweden, 7 times over. 80TWh is about 53 nuclear reactors. or 123 million windmills.
lmao I just finished a report about using nuclear heat to create hydrogen and power a steel forge, nice to see someone's at least applying the hydrogen part of my report
It seems to me that steel is a heavily recycled material, and coke is not required to run an electric arc furnace.. so there is the potential to make "green steel", depending on how the electricity is sourced. Also, while much of Sweden's electricity is generated through hydropower, an almost equal amount is generated through nuclear, and some from burning garbage as well.. even though it may not be used in the steel-making process.
How come the background oriental music when promoting kamikato knifes sounds like traditional Chinese music 😅😂
great video, but you should really start saying 'clean energy' instead of 'renewable', since the latter is non-inclusive towards the clean energy source of nuclear energy. Especially in the case of Sweeden which is a nuclear powerhouse, meaning that this steel is only low-carbon due to the share of nuclear in combination with renewables, mostly hydro. Had they not had the nuclear, their electricity grid would still be partly fossil fuel powered, and there would have been no souch thing as green steel.
Does this new process work for recycled steel? And if so, what kinds of recycled steel can be used? Can e.g., building waste be used? Recycling, where possible, is better for the environment than mining new ore.
Where is that hydrogen production comes from mate, last time I check the energy produce from burning hydrogen is less than seperate hydrogen from water under normal condition
Those knives aren’t Japanese, they’re another rip off from the established titles people
They’re made in China
