Ørsted Secures Exclusive Access To Lower-Emission Steel From Dillinger
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted will be offered the first production of lower-emission steel from German-based Dillinger, subject to availability and commercial terms and conditions. The steel plates are intended to be used for offshore wind monopile foundations in future projects.
These three paragraphs outline the deal.
Under a large-scale supply agreement entered into in 2022, Ørsted will procure significant volumes of regular heavy plate steel from 2024, giving the company access at scale to and visibility of the most crucial raw material in offshore wind while supporting Dillinger to accelerate investments in new lower-emission steel production, according to Ørsted.
The Danish renewable energy giant expects to be able to procure lower-emission steel produced at Dillinger’s facility in Dillingen, Germany, from 2027-2028.
Taking the current technology outlook into account, the reduction of the process-related carbon emissions from production is expected to be around 55-60 per cent compared to conventional heavy plate steel production, Ørsted said.
Increasingly, we’ll see lower emission steel and concrete used for wind turbine foundations.
This press release on the Dillinger web site is entitled Historic Investment For Greater Climate Protection: Supervisory Boards Approve Investment Of EUR 3.5 billion For Green Steel From Saarland.
These are two paragraphs from the press release.
Over the next few years leading up to 2027, in addition to the established blast furnace route, the new production line with an electric arc furnace (EAF) will be built at the Völklingen site and an EAF and direct reduced iron (DRI) plant for the production of sponge iron will be built at the Dillinger plant site. Transformation branding has also been developed to visually represent the transformation: “Pure Steel+”. The message of “Pure Steel+” is that Saarland’s steel industry will retain its long-established global product quality, ability to innovate, and culture, even in the transformation. The “+” refers to the carbon-neutrality of the products.
The availability of green hydrogen at competitive prices is a basic precondition for this ambitious project to succeed, along with prompt funding commitments from Berlin and Brussels. Local production of hydrogen will therefore be established as a first step together with the local energy suppliers, before connecting to the European hydrogen network to enable use of hydrogen to be increased to approx. 80 percent. The Saarland steel industry is thus laying the foundation for a new hydrogen-based value chain in the Saarland, in addition to decarbonizing its own production. In this way, SHS – Stahl-Holding-Saar is supporting Saarland on its path to becoming a model region for transformation.
It sounds to me, that Tata Steel could be doing something similar at Port Talbot.
- Tata want to build an electric arc furnace to replace the blast furnaces.
- There will be plenty of green electricity from the Celtic Sea.
- RWE are planning a very large hydrogen electrolyser in Pembroke.
- Celtic Sea offshore wind developments would probably like a supply of lower emission steel on their door-step.
I would suspect, that Welsh steel produced by an electric arc furnace will match the quality of the German steel, that is made the same way.
H2 Green Steel Raises More Than €4 billion In Debt Financing For The World’s First Large-Scale Green Steel Plant
The title of this post, is the same as that of this press release from H2 Green Steel.
This is the sub-heading.
H2 Green Steel signs definitive debt financing agreements for €4.2 billion in project financing and increases the previously announced equity raised by €300 million. Total equity funding to date amounts to €2.1 billion. The company has also been awarded a €250 million grant from the EU Innovation Fund. H2 Green Steel has now secured funding of close to €6.5 billion for the world’s first large-scale green steel plant in Northern Sweden.
These three paragraphs describe the company and outlines the financing.
H2 Green Steel is driving one of the largest climate impact initiatives globally. The company was founded in 2020 with the purpose to decarbonize hard-to-abate industries, starting by producing steel with up to 95% lower CO2 emissions than steel made with coke-fired blast furnaces. The construction of the flagship green steel plant in Boden, with integrated green hydrogen and green iron production, is well under way. The supply contracts for the hydrogen-, iron- and steel equipment are in place. A large portion of the electricity needed has been secured in long-term power purchase agreements, and half of the initial yearly volumes of 2.5 million tonnes of near zero steel have been sold in binding five- to seven-year customer agreements.
Today H2 Green Steel announces a massive milestone on its journey to accelerate the decarbonization of the steel industry, which is still one of the world’s dirtiest. The company has signed debt financing of €4.2 billion, added equity of close to €300 million and been awarded a €250 million grant from the Innovation Fund. Funding amounts to €6.5 billion in total.
H2 Green Steel has signed definitive financing documentation for €3.5 billion in senior debt and an up-to-€600 million junior debt facility:
Note.
- I first wrote about H2 Green Steel about three years ago in Green Hydrogen To Power First Zero Carbon Steel Plant.
- The Wikipedia entry for Boden in Northern Sweden, indicates it’s a coldish place to live.
- In that original post, H2 Green Steel said they needed €2.5 billion of investment, but now they’ve raised €4 billion, which is a 60 % increase in financing costs in just three years.
Is this Sweden’s HS2?
The Future Of Green Steelmaking
The finances of H2 Green Steel look distinctly marginal.
I have a feeling that green steel, as the technology now stands is an impossible dream.
But I do believe that perhaps in five or ten years, that an affordable zero carbon method of steel production will be developed.
You have to remember, Pilkington developed float glass in the 1950s and completely changed an industry. Today, we’d call that a classic example of disruptive innovation.
The same opportunity exists in steelmaking. And the rewards would be counted in billions.
Thor Offshore Wind Farm To Feature Siemens Gamesa’s Newly Launched GreenerTowers
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Siemens Gamesa has revealed its GreenerTower, a wind turbine tower made of more sustainable steel. The company already closed its first order with RWE to feature 36 of the GreenerTower units at the 1 GW Thor offshore wind project in Denmark.
This is the first paragraph.
Today, tower production accounts for more than one-third of all wind-turbine-related CO2 emissions, according to Siemens Gamesa.
Siemens Gamesa’s new GreenerTower will ensure a CO2 reduction of at least 63 per cent in the tower steel plates compared to conventional steel.
Siemens Gamesa also claim this.
If all towers installed by the company in one year were exchanged with GreenerTowers, it would be the same as removing more than 466,000 cars from the roads in Europe for a year.
The first supplier to be qualified is Salzgitter AG.
- I wrote about Salzgitter’s green steelmaking in WindH2 Hydrogen Project Commissioned In Germany.
- Only a maximum of 0.7 tonnes of CO2-equivalent emissions are permitted per tonne of steel while maintaining the same steel properties and quality.
- Salzgitter’s electric furnaces will be fed with green electricity produced by renewable energy sources.
- Salzgitter AG have recently signed a Power Purchase Agreement (PPA) with Iberdrola.
- It looks like Salzgitter AG are going both the electric and hydrogen route to green steel.
I suspect over the next few years, we’ll be seeing more steel products made with green steel.
In this case, I suspect that Siemens Gamesa could use the same production process with very little modification, which is a great advantage.
‘Czech Sphinx’ Power Plant Intended To Keep Lights On
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
The businessman known as the “Czech Sphinx” is set to expand his position in Britain’s energy market after securing subsidy contracts to build a new gas-fired power plant and battery storage project.
As I needed to find the answers to particular questions, I looked for and found the original press release on the EP Holdings web site, which is entitled EPH Will Build A New Gas-Fired Power Plant And Battery Storage Facility In The UK At A Cost Of More Than £1 billion.
These statements describe the project.
- It will be a 1700MW high efficiency H-class CCGT power project and a 299MW 2-hour battery storage project
- The power station will be built on the site of the former Eggborough coal station in East Yorkshire.
I find this to be the most significant paragraph.
The high efficiency H-class CCGT project will be the single largest flexible generation asset to be commissioned in the UK since 2012, whilst the battery project will also be one of the largest to be built in the UK to date. Given the site’s close proximity to existing National Grid infrastructure and a number of proposed CCUS and hydrogen pipeline routes, under EPUKI’s plans these projects will make a significant contribution to the UK’s energy transition and security for years to come.
This map from OpenRailwayMap, shows the relationship between the Eggborough site and the nearby Drax power station.
Note.
- The Eggborough power station site is in the South-West corner of the map and is identified by the rail loop. which was used to deliver the coal.
- The Drax power station site is in the North-East corner of the map and is similarly identified by a rail loop.
- There is a high voltage transmission line connecting the two power stations.
- As the crow flies is about eight miles between Eggborough and Drax.
This Google Map shows the Eggborough power station site.
Note.
- The remains of the eight cooling towers are visible at the North of the site.
- The large circular black area in the middle is the coal yard with its rail loop.
- It is a large site.
I have looked in detail at the cleared area in the North-West of the site and the pylons of the connection to Drax are still visible.
So it looks like there is still an electrical connection of some sort to the site.
According to Wikipedia, the original coal-fired power station had a nameplate capacity of 1960 MW, so I suspect that a modernised electricity connection to handle the maximum near 2,000 MW of the new station would be possible.
This map shows the Zero Carbon Humber pipeline layout.
Note.
- The orange line is a proposed carbon dioxide pipeline
- The black line alongside it, is a proposed hydrogen pipeline.
- Drax, Keadby and Saltend are power stations.
- Keadby and Saltend are gas-fired power stations.
- Easington gas terminal is connected to around twenty gas fields in the North Sea.
- The terminal imports natural gas from Norway using the Langeled pipeline.
- The Rough field has been converted to gas storage and can hold four days supply of natural gas for the UK.
- To the North of Hull is the Aldbrough Gas Storage site, which SSE plan to convert to hydrogen storage.
The Eggborough power station site is about eight miles to the South-West of Drax.
I don’t suspect that connecting the Eggborough site to the carbon dioxide, gas and hydrogen pipelines will not be the most challenging of tasks.
So when the press release says.
Given the site’s close proximity to existing National Grid infrastructure and a number of proposed CCUS and hydrogen pipeline routes, under EPUKI’s plans these projects will make a significant contribution to the UK’s energy transition and security for years to come.
The company is not exaggerating.
It appears that carbon dioxide, gas and hydrogen pipelines can be developed and National Grid connections can be reinstated.
Eggborough Will Not Be Alone
From the EP Holdings press release, it appears that the Eggborough power station will be fitted with carbon-capture and will be hydrogen-ready.
This will make it the second power-station in the area to be fitted out in this way, after SSE’s planned Keadby 3, which is described in this page on the SSE web site in this document, which is entitled Keadby 3 Carbon Capture Power Station.
They could also be joined by Keadby Hydrogen power station.
This would mean that zero-carbon power stations in the area could include.
- Eggborough Gas/Hydrogen – 1700 MW
- Eggborough Battery – 299 MW
- Keadby 3 Gas/Hydrogen – 910 MW
- Keadby Hydrogen – 1800 MW – According to this Equinor press release.
Note.
- The Eggborough Battery pushes the total zero-carbon capacity over 4500 MW or 4.5 GW.
- The various Dogger Bank wind farms are to have a total capacity of 8 GW within ten years.
- The various Hornsea wind farms are to have a total capacity of 5.5 GW in a few years.
I would expect that the zero-carbon power stations would make a good fist of making up the shortfall, when the wind isn’t blowing.
Drax, Keadby 1 And Keadby 2 Power Stations
Consider.
- Drax has a nameplate capacity of 3.9 GW, of which 2.6 GW is from biomass and the rest is from coal.
- Keadby 1 has a nameplate capacity of 734 MW.
- Keadby 2 has a nameplate capacity of 734 MW.
How much of this capacity will be fitted with carbon capture, to provide extra zero-carbon backup to the wind farms?
Green Hydrogen From Surplus Wind Power
At times, there will be an excess of renewable energy.
I suspect, an order for a large electrolyser will be placed soon, so that surplus renewable energy can be used to create green hydrogen.
This will be stored in the two storage facilities, that are being developed in the area; Aldbrough and Rough.
Controlling The Fleet
I am by training a Control Engineer and this fleet can be controlled to provide the electricity output required, so that the carbon-dioxide produced is minimised and the cost is at a level to the agreement of producers and users.
Conclusion
It looks like in excess of 20 GW of reliable zero-carbon energy could be available on Humberside.
I’m sure British Steel would like to by a lot of GWhs to make some green steel at Scunthorpe.
Rolls-Royce To Develop mtu Hydrogen Electrolyser And Invest In Hoeller Electrolyser
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the three main points in the press release.
- Holdings in start-up companies in northern Germany secure Rolls-Royce Power Systems access to key green hydrogen production technology.
- Electrolysis systems for several megawatts of power.
- First demonstrator in 2023 using a Hoeller stack.
This is the introductory paragraph to the deal.
Rolls-Royce is entering the hydrogen production market and acquiring a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division. Hoeller Electrolyzer, based in Wismar, Germany, is an early-stage technology company that is developing highly efficient polymer electrolyte membrane (PEM) stacks, under the brand name Prometheus, for the cost-effective production of hydrogen.
This page on the Hoeller Electrolysis web site gives details of Prometheus.
- Hoeller are planning small, medium and large electrolyser modules, the largest of which is rated at 1.4 MW.
- Load changes of between 0 and 100 % within seconds.
- Cold start capability.
- It will produce 635 Kg/day.
- They are talking of a cost of 4€/Kg.
It all sounds good to me.
This paragraph is from the press release.
Founded in 2016, Hoeller Electrolyzer has positioned itself, with Prometheus, as one of the few highly specialized expert players in the field of high-efficiency PEM electrolysis stacks. Its founder, Stefan Höller, has more than a quarter of a century’s experience of developing electrolysis technology and has already registered 14 patents connected with Prometheus. Particularly high efficiency is promised by special surface technologies for the bipolar plates which significantly reduce the use of expensive precious metals platinum and iridium as catalysts, as well as increased output pressure.
I know a small amount about electrolysis and feel that Rolls-Royce may have got themselves a high-class deal.
Rolls-Royce’s large German presence in companies like mtu, will also help to smooth any doubts about the deal.
This paragraph indicates a shared belief.
Rolls-Royce and Hoeller Electrolyzer are united by a shared belief in the opportunity of zero-carbon energy – both for power supply and the propulsion of heavy vehicles. With decades of experience and systems expertise, Rolls-Royce is going to develop a complete electrolyzer system and has a global sales and service network, which opens up the potential for significant worldwide sales.
But perhaps, this is the most significant paragraph of the press release.
Armin Fürderer, who heads up the Net Zero Solutions business unit of Power Systems, said: “We’re going to launch electrolyzers with several megawatts of power right from the start. A total output of over 100 megawatts is conceivable by combining several electrolyzers.”
A quick search of the Internet, indicates that 100 MW is the size of the world’s largest electrolysers.
Applications
I can see applications for these large electrolysers.
Rolls-Royce Power Systems
This is a sentence from the press release.
Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division.
The Rolls-Royce Power Systems web site, has this mission statement.
The Power Systems Business Unit of Rolls-Royce is focused on creating sustainable, climate neutral solutions for drive, propulsion and power generation.
In Rolls-Royce Makes Duisburg Container Terminal Climate Neutral With MTU Hydrogen Technology, I describe one of Rolls-Royce Power Systems projects.
The title of this post, is the same as this press release from Rolls-Royce.
This is the first sentence.
Rolls-Royce will ensure a climate-neutral energy supply at the container terminal currently under construction at the Port of Duisburg, Germany.
There is also this Rolls-Royce graphic, which shows the energy sources.
It would appear batteries, combined heap and power (CHP), grid electricity, hydrogen electrolyser, hydrogen storage and renewable electricity are being brought together to create a climate-neutral energy system.
Note.
- The system uses a large hydrogen electrolyser.
- I suspect the hydrogen will be generated by off-peak electricity and local renewables.
- Hydrogen will probably power the container handling machines, ships, trucks, vehicles and other equipment in the port.
Hydrogen appears to be used as a means of storing energy and also for providing motive power.
I would suspect, the ultimate aim is that the port will not emit any carbon dioxide.
Other ports like Felixstowe and Holyhead seem to be going the hydrogen route.
Refuelling Hydrogen Buses and Charging Electric Buses
If you look at the Duisburg system, I can imagine a similar smaller system being used to refuel hydrogen buses and charge electric ones.
- The hydrogen electrolyser would be sized to create enough hydrogen for a day or so’s work.
- Hydrogen would be generated by off-peak electricity and local renewables.
- If an operator bought more buses, I’m certain that the architecture of the electrolyser would allow expansion.
- Hydrogen fuel cells would boost the electricity supply, when lots of buses needed to be charged.
- Any spare hydrogen could be sold to those who have hydrogen-powered vehicles.
- Any spare electricity could be sold back to the grid.
It should be noted that manufacturers like Wrightbus have developed a range of hydrogen and electric buses that use the same components. So will we see more mixed fleets of buses, where the best bus is assigned to each route?
I have used buses as an example, but the concept would apply to fleets of cars, trucks and vans.
Green Hydrogen
Large efficient electrolysers will surely be the key to producing large quantities of green hydrogen in the future.
It appears that about 55 MWh is needed to produce a tonne of green hydrogen using existing electrolysers.
The Hoeller electrolyser appears to be about 53 MWh, so it is more efficient.
Green Hydrogen From An Onshore Wind Farm
If you look at the average size of an onshore wind farm in the UK, a quick estimate gives a figure of 62 MW. I shouldn’t expect the figure for much of the world is very different, where you ignore the gigafarms, as these will distort the numbers.
An appropriately-sized electrolyser could be added to onshore wind farms to provide a local source of hydrogen for transport, an industrial process or a domestic gas supply for a new housing estate.
A single 5 MW wind turbine with a capacity factor of around 30 % would produce around 680 Kg of green hydrogen per day.
Green Hydrogen From An Offshore Wind Farm
There are basic methods to do this.
Put the electrolyser onshore or put the electrolyser offshore and pipe the hydrogen to the shore.
I think we will see some innovative configurations.
In ScotWind N3 Offshore Wind Farm, I described how Magnora ASA are developing the ScotWind N3 wind farm.
The floating turbines surround a concrete floater, which in the future could contain an electrolyser and tankage for hydrogen.
The ScotWind N3 wind farm is designed to be a wind farm rated at 500 MW.
I can see an electrolyser on the floater, of an optimal size to make sure all electricity is used.
Pink Hydrogen
Pink hydrogen, is zero-carbon hydrogen produced using nuclear-generated electricity.
There are industrial processes, like the making of zero-carbon chemicals, concrete and steel, that will require large quantities of zero-carbon green or pink hydrogen.
Rolls-Royce are developing the Rolls-Royce SMR, which will be a 470 MW small modular nuclear reactor.
One of these placed near to a steel works and coupled to one or more 100 MW electrolysers could provide enough zero-carbon electricity and hydrogen to produce large quantities of zero-carbon green steel.
Manufacturing
Rolls-Royce and their subsidiaries like mtu, seem to be extensive users of advanced manufacturing techniques and I would expect that they can improve Hoeller’s manufacturing.
Research And Development
The press release says this about the founder of Hoeller.
Its founder, Stefan Höller, has more than a quarter of a century’s experience of developing electrolysis technology and has already registered 14 patents connected with Prometheus.
If Rolls-Royce can develop and support Stefan Höller and his team, development could easily go to a higher level.
Conclusion
I think that Rolls-Royce have taken over a company, that will in the end, will design excellent efficient electrolysers.
Nuclear-Enabled Hydrogen – How It Helps To Reach Net Zero
The title of this post, is the same as that of this article on Power Engineering.
These are the first two paragraphs.
Nuclear enabled hydrogen is zero carbon, has low cost energy input, is large scale and offers co-location synergy and energy system connectivity.
With the revival of interest in nuclear energy, interest is growing in the potential for nuclear-enabled hydrogen, otherwise sometimes known as ‘pink’ hydrogen, to meet the anticipated demand for hydrogen at scale.
The article is certainly a must-read.
Topics covered include.
- Co-location of pink hydrogen production with industrial clusters, where heat can also be provided.
- The production of hydrogen on a large scale.
- The use of high temperature electrolysis, using steam from the nuclear plant.
I particularly like the idea of combining a small modular nuclear reactor with high temperature electrolysis to generate hydrogen for local industry like a steelworks or chemical plant.
The Complex Web At Sunderland
This article on the BBC is entitled Nissan Announces Major UK Electric Car Expansion.
This is the first few paragraphs.
Nissan has announced a major expansion of electric vehicle production at its car plant in Sunderland which will create 1,650 new jobs.
The Japanese carmaker will build its new-generation all-electric model at the site as part of a £1bn investment that will also support thousands of jobs in the supply chain.
And Nissan’s partner, Envision AESC, will build an electric battery plant.
I think there is more to this than meets the eye!
We wait several years for a battery gigafactory to come along and then two come along in a month or two; Blyth and Sunderland. On television today, a BBC reporter talked of eight possible battery gigafactories in the UK.
Lithium Supply
Where do they all think the lithium will come from, as some say there’s a world-wide shortage?
The only explanation, is that the UK government and the gigafactory owners have bought into a secure source of lithium, that is convenient for or easily transported to the North-East.
I am very suspicious that Cornish Lithium or British Lithium have found something bigger than anybody expected.
The numbers don’t add up otherwise!
Lithium Refining
On the other hand, it appears that lithium needs a lot of electricity to extract the metal from the ores, as electrolysis is used.
But with all the windpower being developed off the North-East Coast, there could be more than enough to refine the lithium.
Remember too, that lithium has applications in defence and aerospace applications, when alloyed with magnesium and aluminium.
So could a substantial lithium refining capability be built in the North-East?
The Chinese View
In The Times, Lei Zhang, who is chief executive of Envision also said he liked our masses of offshore wind power, so perhaps the Chinese want to produce green batteries in Sunderland after refining the lithium in the North-East?
Conclusion
We probably need battery-electric cars built from green steel, fitted with green batteries and charged with green electricity.
Is the Gigawatts of offshore wind electricity in the North-East luring the battery and car makes to the area.
Could we also see green steel manufacturing on Teesside?
BECCS Beats Hydrogen For Decarbonizing Steel In Europe: ArcelorMittal
The title of this post, is the same as that of this article on S & P Global Platts.
This is the first paragraph.
Bioenergy with carbon capture and storage (BECCS) offers a more cost-effective, readily available solution for decarbonizing the steel industry in Europe than clean hydrogen, steel producer ArcelorMittal’s head of strategy David Clarke said May 17.
So what do they mean by bioenergy?
To make iron from iron ore, you need a reducing agent like carbon or hydrogen.
Iron ore is rich in oxides of iron.
The carbon is usually some form of coal, which produces large amounts of carbon dioxide with the oxygen from the iron oxides.
Hydrogen produces lots of water with the oxygen.
David Clarke of ArcelorMittal explains the process in the article.
“We know biomass worked as a replacement for coal,” he said. “We’ve been using it in our operations in Brazil and other places for many, many years. We have a project in Belgium that we’ll be starting up next year using waste wood, using that to make bio-coal,” with a project to take the emissions from the bio-coal to produce bioethanol.
Is this a case of Back-To-The-Future? If I remember my history, didn’t Iron Age men use charcoal to smelt iron and other metal ores?
If those scientists from Velocys can make Sustainable Aviation Fuel and biodiesel from household waste and used disposable nappies, can they apply their magic to make bio-coal?
I see great cost advantages with this process, as surely it would enable existing blast furnaces to be used, provided they were fitted with carbon capture and storage.
Orsted In Gigawatt-Scale Offshore Wind To Green Hydrogen Plan With Steel Giant ArcelorMittal
The title of this post, is the same as that of this article on Recharge.
The title says a lot and at the heart of the plan is a 1 GW electrolyser.
Now that is enormous.
Will it be made in Rotherham by ITM Power?
The article is a must read.
The Anonymous Widower
