Green Hydrogen making Green Steel. Is 2024 the breakthrough year?

Рет қаралды 124,001

Күн бұрын

Global steel production is responsible for more than 3 billion tonnes of carbon dioxide equivalent emissions every single year. That needs to change quickly, and the folks in the steel industry know it. Huge efforts are being made to decarbonise their processes, and the most promising method is to use green hydrogen to replace coking coal to remove oxygen from iron ore. So, has anyone cracked it yet?

Port Talbot steel works, one of the largest employers in Wales, is set to lose up to 3000 jobs as the plant installs electric arc furnaces. Demonstrations have been held against the owner, Tata Steel, and their decarbonisation plans.

it is a sad consequence of technological change that jobs are often impacted negatively. It has always been this way going back hundreds of years. The new technology may eventually create spin off jobs in other sectors but at the present time those jobs tend to be higher skilled types that many put out of work in older technology industries will not be able to be trained for. Older industries have more manual processes so require more people. The new technology usually incorporates a high degree of automation and a reduction in manual processes. So it is the older and less skilled worker that usually carries the can and governments are going to have to change their tune about pointing the finger at some unemployed people and labeling them as bludgers.

Sweden does not have enough electricity production to cover any reasonable scale of green steel production. To produce all the required green hydrogen with renewable energy is a pipe dream.

It will be great when adoption of greener steel initiatives become more widespread. Talked to a friend who works with steel, creating assemblies for construction projects, and he said the main issue is they have to import green steel from so far away that the transportation emissions eat up much of the emission savings gained during production. It's very obviously still good to buy green steel to support market growth for producers but eliminating the additional transport emissions seems pretty crucial.

Another compelling approach involves the use of hydrogen plasma to directly melt and reduce iron into steel. A pilot plant for this method has been constructed by voestalpine in Austria. The Process is called SuSteel And then there is noteworthy paper published in Nature addressing the management of red mud, a byproduct of aluminum production containing up to 60% iron, albeit being a hazardous material. The study demonstrated that melting it in an arc furnace under a hydrogen environment allows the smelting process without the need for additional additives.

Another huge problem with this process is the iron ore must be over 67% . Currently only 3% of world trade in iron ore is over 67%. The majority is around 62%. How to get the concentration up? VERY expensive and energy intensive. Grind all that iron ore into a powder, then add water and gravity, magnetic, separate out the rock. Pump the remaining sludge into a tailings pond. The cost of upgrading iron ore is about 5 times the cost of direct ship ore. Also, a couple million tons a year of steel barely registers. Current annual production is just under 2,000 million tonnes.

@Quickshot0 3 ай бұрын

It is indeed not that much on the worlds scale, but on the other hand being able to produce millions of tons a year from a facility is a big step up in maturing the technology and getting a good grasp on the challenges one needs to meet. So in that sense this is a pretty big improvement, as it makes more clear what kind of costs one can expect as well as if there are any further significant improvements possible.

@Anopheles6 3 ай бұрын

@@Quickshot0 Yes. With costs, we also need to remember that all the estimates (30% more, etc) is assuming that all inputs are still produced and provided with fossil fuels. If you add everything downstream produced with green energy, costs are 3 or more times as much. The world isn’t prepared to pay this much more for everything. I’m also assuming their cost for iron ore is a local, upgraded ore or pellets. The production cost of direct ship iron ore is on the order of $20/t, not including shipping, etc. The production cost of upgraded ore is on the order of $100/t, including mining, infrastructure and production costs. But it also commands a higher price on the market. Still not as profitable as direct ship ore.

Yes, there are more impurities in the intermediate iron. But that's not the final product. You just purify out the bits you don't want when you go and make the steel (immediately) anyway.

Something to keep an eye out for over the next decade, is the North Sea artificial energy island being built by the Danish government in collaboration with a host of independent green energy suppliers. The project aims to initially bring CO2 neutral clean energy to over 10 million homes in Europe, and become a central hub for expanding offshore green energy capture and green hydrogen production for heavy industries and transport. The project was accepted in 2020, and greenlit in 2021 by the other European partners in the UK, Germany, Netherlands, and other neighboring countries who will benefit from the project. This will help fuel the mass scale adoption of carbon neutral electricity and green hydrogen (that up until now has been mostly subsidized through independent firms and limited budgets -all that is going to change). However, it is of course important to keep in mind that this is the largest island construction in human history, initially with almost 3x as much artificial land as the islands of Dubai -all of it with the sole purpose of green offshore energy production at a multi-billion Euro scale. So things can change and deadlines will be hard to maintain - as will budgeting. No one in the world has done this before, so it must be regarded as potentially the most ambitious pilot project ever. This is a project carried out by a nation with a population of less than 6 million people. Scale is not what matters. The will to do what's right, that's all that matters. The will to act. Everyone need to step up their game instead of looking to their neighbors and complaining they aren't doing their share. Just do yours, eventually others will follow. If Denmark with 6mil pop can do this, the US for instance with +300mil pop can at least do the same.

Great overview, thanks! I think the key is this: 1. The fact that these methods are now close to being implementable at industrial scale and not TOO far off regular steel prices means that carbon pricing for steel in major economic zones is becoming a lot more realistic. 2. Many of the technologies that the process interacts with (renewable energy sources and hydrogen conversion) are still improving significantly, so the remaining price gap is likely to close further. That's why I think these technologies are a very good sign for the future, even if their immediate impact will be of limited scale. Especially because these do not appear to be complex "unicorn technologies" that never solve fundamental issues and never make it into widespread adoption, but something that can already be built with current tech and now merely requires some more operational experience to become a basic tool of the industry.

Hydrogen has long been in use in various industrial processes, the big problem being how it is made. Most by far is made by steam reduction of methane, resulting in an enormous carbon footprint, thus the push to greenify it by using electrolysis based on renewable energy.

@allangibson8494 3 ай бұрын

30% of global natural gas production is used to make hydrogen. It is mostly used to make ammonia as a step to making nitrates for fertiliser. The carbon dioxide generated is a waste product to get the oxygen out of the air used as a nitrogen source.

Sweden and Finland are building a green hydrogen system around the Baltic Sea's Gulf of Bothnia and they will connect everything with a hydrogen trunk pipe. The hydrogen will indeed be used for steel first. Later when they have more capacity perhaps it will be used for peak electricity/heat production.

@@atvheads Hydrogen is only a part of the energy. They won't recycle electricity through the hydrogen process and there is plenty of electricity that will still be used by the arc furnaces. They will just replace the coking coal with green hydrogen. Furthermore there will be HUGE off-shore wind farms in the Gulf of Bothnia and this power will have to go somewhere. Hydrogen production is a good candidate to soak gigawatts of windpower. Eventually chemical plants, fertilizer plants, power plants and other industrial users will join the pipe. There are also plans to connect the pipes to Estonia and Denmark. The only part of the plans I'm really skeptical is the plan to use the hydrogen to fuel heavy trucking going up and down both Sweden and Finland and which is currently powered by diesel. I have serious reservations about the feasibility of hydrogen trucks.

@@EdSurridge This is the very big problem: " If it can work towards CO2 reduction "... So far it has failed and is very expensive, I can't find the reference for who calculated that for carbon capture to work well enough by around 2050 (might have even been on this channel.. Dave?), it would need more electricity than the world produces now... Carbon Capture is a fig leaf for the fossil fuel industry to continue burning fossil fuels, with the relatively little CO2 so far captured often used to enhance the recovery of oil (to burn) in near depleted wells where the last bits of oil are hard to extract. Perhaps the best summary, with I understand accurate figures so is well worth checking out, was produced by The Juice Media, titled "Honest Government Ad | Carbon Capture & Storage". Their tone is somewhat flippant, even sarcastic, but the science and numbers there are good, and is most probably a reliable description even though the tone is a ... somewhat earthy Aussie style...

I think that you may have noticed in my comments online if you have seen them, and Dave (along with many others) ... ... just possibly ... ... may have mentioned on his channel, that the fossil fuel industry does not quite have the greatest history of integrity when describing issues around Climate Change... Although I am not aware of any research supporting this suggestion, but it would not surprise me if the fossil fuel industry has killed more people than tobacco and malaria combined since the scientific community have been clear on Climate Change from about 45 years ago.

Ocean-based carbon capture isn't stupid. It's not a gimmick, and it's actually intended to remove CO2 at a gigatonne scale. On the topic of clean energy for producing green hydrogen for steel production, and various other things, here in Canada, we have a massive amount of hydropower. We have 160GW of untapped hydropower in 9 out of 10 provinces, and not including the territories. The Northwest Territories alone, we there's 11.5 (or 13 GW if you include the Slave River between the NWT and Alberta) of untapped hydroelectric potential. Hydropower is not just a source of electricity generation. It's a means of achieving grid stability and can help integrate tens of GW of wind, solar, and also inflexible sources of energy, like nuclear.

Steel in many uses can be replaced by carbon fiber-reinforced polymers which are 3 times as strong. It can be produced in a CO2 rich atmosphere such as cement manufacture by passing the gas through an electrolysis system to make carbon nanostructures. There are several Canadian companies doing this. In the construction industry it can replace steel rebar, steel girders and for supporting weak beams and structural joints. It can then make reinforced concrete structures much thinner, hence reducing the carbon footprint of both the steel and the concrete. It is probably more expensive than steel but may not be if there was carbon taxes. Dave, a good subject for one of your programs.

Just have a think: It is possible to make things much easier, the problem is that, the cost reductions make companies uneasy. You can build machines that is much greener, and cheaper to operate. If you remove the Gas tank off of heavy equipment, and incert its own personal powerplants. You need only enough electrical power to operate. Talked to the manager of the power company in town, and explained that once i was ready to show a functional proto-type let them know, because unlike most energy sources this one can be mobile, unless one makes a much larger system. basically its particle electric.

Great episode! It did make me have a think, a rethink even. I've always considered steel production such a small part of the overall problem that is just moderately interesting at the moment, but as we've reached a point where power generation and road transport have developed far enough for making the rest of that transition mostly a "downhill journey", economically viable low carbon steel production remains a difficult challenge. As steel production with current common techniques cause similar amounts of CO2 per unit of mass produced as use of fossil fuels it seemed so strange to me that steel production was such a big part of the problem, but apparently we use almost half as much steel as we use oil. I think it will be difficult to transition the steel industry to really low carbon production, but there's also a silver lining, steel is easy to recycle. Recycling steel requires much less energy than producing it from ore. So, the "new" steel we need is the amount we want to increase current use with, plus whatever part we let turn into rust. We do recycle a lot of steel, and if we get even better at that, and place an international, and relevant, price on carbon emissions, using steel slightly more economically, we might be able to reduce the production of new steel quite significantly, without too much of those minor inconveniences some people find catastrophic. Here in Sweden there's already been one public "debate" about how much green steel production would increase the price of electric power, as if we're going to make the shift entirely, soon, and without any consideration to the grid situation or much additional power generation. If they're planning to run the electrolysers at their convenience without any regard to situation on the grid, well, that would probably be problematic. If they can adjust their production somewhat to the situation in the grid, it might even reduce the need for energy storage. It's much easier to store iron ore and steel than it is to store the energy it takes to turn that ore into steel. Not running at full capacity means lost revenue, but when price of electricity varies between negative and absurdly high, some level of control of the power draw might be needed to make it feasible at all.

@josepheridu3322 3 ай бұрын

This may be the best way to save energy. Focus first on the industries that spend the most and are centralized enough to be regulated and modified to use green Hydrogen. No solar or wind energy should be lost, it should be stored as hydrogen when possible.

7:15 they won't just have access to plenty of local hydro power, the city of Boden is also right on Ore Line railway (Malmbanan) that takes iron ore from the LKAB mines in Kiruna and Malmberget (town name that literally means "the Ore Mountain") to the coast (where the SSAB steel plant is located). btw - SSAB's largest shareholder is the LKAB mining company which in turn is owned by the Swedish state. Vattenfall the power company is also owned by the Swedish state. So the Hybrit project mentioned first in the video is quite closely tied to the Swedish state.

Apart from MOE, there's also low-temperature electrolysis of iron ore. Unlike MOE, it produces sponge iron intead of steel, but the technological risks seem to be much lower. The potential huge advantage of electric processes is that you save the big (~50%) energy loss from producing hydrogen as well as the capex for the electrolysers and other hydrogen infrastructure.

A worthy topic. I have visited a number of steel making plants of the traditional variety and they were very impressive. However getting back to the topic here, my own country, the UK, has effectively sold all our iron and steel making operations to Indian and Chinese companies. In order to wave the green flag, the government are subsidising Tata to shut down the blast furnaces and replace with electric arc furnaces. At first glance, that would reduce carbon emissions (depending on the source of electricity), but they can only process pig iron and scrap iron/steel. They cannot produce pig iron which will then have to be imported from India and China which will increase production (and profits) from their blast furnaces. What a surprise. As the production of hydrogen from electrolysis is very inefficient, There is unlikely to be enough electricity supply available to satisfy global demand for the hydrogen needed. It certainly does look like a workable system, but perhaps the answer to the electricity supply for hydrogen production would be small modular reactors at the steel plants. I do not know how things will develop, but I predict that our government will announce that the UK is a "World Leader" in green technology (translation:- we don't make the stuff anymore but we are spending a lot of money subsidising foreign companies).

My thoughts- Start strong and get stronger, fast. All the money raised, is then divided equally amongst every person living in that state. The rich use more carbon, so it will benefit the poorer. My addition, to what is a commonly held strategy, is that the govt., gives out the money at the beginning of the year, so no one can ever complain they're being robbed, plus offering the option of borrowing three, five years of estimated carbon tax, to carry out energy-saving works, insulation, solar, EV. The better the energy saving, the quicker the project pays for itself. Providing such a strong incentive, plus the means to act, could be transformative.

And "carbon taxes" should just be relative to whatever the zero/low carbon alternative is. In the case of steel, they would pay some percentage of the difference between the current methods and the zero carbon methods, and that percentage would grow over time until it eventually reaches 100%. This works doubly well, because not only does it encourage doing more of the zero carbon stuff, but it also further encourages them to increase the efficiency of the zero carbon stuff, since the closer they get to price parity, the less they pay too.

It's great to see actual progress on this issue over the last few years. I know it isn't much now, but creating a sustainable commercially-viable technology or process is often the hardest hurdle, while increasing market adoption is easier. What would really help is governmental support, but we'll have to wait and see for that. Btw, DCC is indeed an immature technology that isn't helping much at the moment, but why can't carbon capture be used directly on waste gases from the steel-making process? The sheer air pressure from an active process like this should provide a pressure differential that can help power the process, and the CO2 is in a high concentration, enabling more effective carbon absorption....?
