Says Anne Cathrine Syversen from Powered by Telemark, an industrial and technology cluster. She is also the project manager of Grenland Industrial CO₂ Capture and Storage’s (GICCS). The research project was launched in November last year and will run until 2024. It has a budget of NOK 11.4 million, with half of its funding coming from the process industry and the other half from the CLIMIT programme. The starting point for this was the cluster’s roadmap, which identified 25 projects that will contribute to making Grenland the world’s first climate-positive industrial region.

This is a formidable task as the process industry in Grenland, with its 2.4 million tonnes annually, accounts for appr. 20 per cent of the Norwegian industry’s CO₂ emissions. When the capture plant associated with the Longship project at Heidelberg Materials’s factory in Brevik is commissioned in two years’ time, emissions will be reduced by around 400,000 tonnes a year. About 800,000 tonnes will be cut thanks to the recalibration of Yara’s fertiliser production process to incorporate green power as part of the HEGRA project.

Joint solutions to get rid of all climate emissions

– GICCS is focused on investigating and calculating how to annually eliminate appr. 1.2 million tonnes of emissions from the process industry in the region. This will be achieved through a joint investment and shared solutions that will limit costs incurred by individual companies, says Syversen.

SINTEF Industry in Porsgrunn is responsible for coordinating the different work packages. They are working in partnerships with researchers at the University of South-Eastern Norway. Kristian Aas at SINTEF Industry is the coordinator for all project activities and says that the cooperation with companies to collect data has been good.

Will use available waste heat

– In the first phase, we identified how much of the waste heat generated by the process industry can be redirected for the operation of facilities for capturing CO2. This is essential to keep energy costs as low as possible. In the next phase, we will explore whether there is also waste heat from other nearby industrial stakeholders available and consider the use of high-temperature heat pumps. Some electrical power will be needed to operate the facilities with compressors and other equipment, and we will quantify this need, says Kristian Aas

Extensive research required

Grenland is Norway’s largest industrial region, supporting around 6,000 jobs in the area. The biggest emitters are Ineos Rafnes, Inovyn Norway, ERAMET Porsgrunn and Heidelberg Materials (with total emissions of approximately 400,000 tonnes of CO₂ that are not planned captured in the Longship plant). The idea is that an absorber for CO₂ containing flue gases will be established at each of the companies. This will be connected by a pipeline leading to a standard ‘stripper’ where greenhouse gases will be separated in a capture process based on amines. This is the most mature of the technologies for capturing CO₂. The captured substances will then be stored in liquid form and transported from a shared warehouse to a reservoir.

– In this respect, the location of businesses in relation to the fjord will play a role in determining whether one or more capture facilities should be established. We will also have to assess whether it is appropriate to use alternative technologies for capturing CO₂ that require less heat based on the flue gases present. But if we find that amine technology is the preferred option, then we need to find out how high a temperature this solvent can have in the planned pipeline, says Aas.

Draws on strong and broad expertise

To provide solutions to these and many other technical challenges, researchers are drawing on expertise from throughout SINTEF. Nippon Gases, a world-leading company in the field of CO₂ handling, is also involved. Bluegreen is contributing expertise in thermoplastics, while Pipelife, who manufacture systems for plastic pipes, are also on board. Bouvet will assess sensors and IT solutions.

Another important partner is Herøya Industrial Park, which is the intended host site for these joint solutions. The project has also engaged Norsk e-fuel and Nordic Electrofuel to investigate the possibility of utilisation of CO₂ in the region.

A project with significant transfer value

– The project is divided into five work packages and a total of 29 interim reports are planned before the delivery of a final report in two years’ time. This will ensure that participants have plenty of opportunities to provide their input and views before the final summary of recommendations for the construction and operation of facilities is submitted, Anne Cathrine Syversen adds.

SINTEF has also created a separate website for the project which will be updated on an ongoing basis with assessments and results as research progresses.

– Disseminating knowledge during the project is important because we believe that what we arrive at in terms of recommended solutions in Grenland will also be of use to other industrial regions facing the same challenges as we do, both in Norway and in Europe. It is about being able to maintain production and employment in the process industry, and thus the welfare of people and countries, without harming the climate and environment. Without the funding and support offered by industrial companies and CLIMIT, we would not have been able to carry out such extensive and thorough research. We are very grateful that Gassnova, thanks to its presence in Porsgrunn, has been and remains an enthusiastic promoter of the project. We feel a sense of duty, and we will deliver, promises Anne Cathrine Syversen.

CLIMIT has provided NOK 8 million in support to CAPEWASTE

The CLIMIT programme is working to adapt to an ever-changing world and support for the waste management industry is one of the new industries seeing more and more applications for support. This is a huge industry with facilities that will have to make both minor and major changes in order to implement CCS. At the EGE Oslo Kommune plant at Haraldrud, there was a need to see what changes had to made for carbon capture to become a reality at the plant for when it undergoes redevelopment in 2030.

The CLIMIT project “CAPEWASTE” has studied the challenges associated with capture technology based on oxy-fuel combustion which uses oxygen instead of air in the waste incineration process. The flue gas from this process is composed entirely of CO₂ and steam, something which makes it easy to separate the CO₂ simply through the condensation of water. It is an amazingly innovative solution, and no plant like this has ever been built before.

Carbon capture in the energy recovery sector

Carbon capture from the waste sector is an industrial initiative that addresses these challenges with the added potential for being carbon negative. Implementation of CCS at the new Haraldrud plant has been boosted by the positive results from the full-scale CCS feasibility study carried out by Gassnova, as well the infrastructure to transport the CO₂ to the Port of Oslo and then to the offshore storage sites in the Smeaheia area, which is set to be operational by 2024.

R&D partner SINTEF Energi carried out an experimental study of how to efficiently burn household waste in an oxy-fuel combustion atmosphere and then how to scale up the technology through the help of numerical simulation. Through close international collaboration with partners at an associated project (NuCA) in Germany, the technology has been further tested at pilot scale. The results have been exchanged across borders.

• “It’s really fantastic that we built this partnership with Germany, which has been a key CCS partner in Europe also through, the ACT project NEWEST-CCUS, which began in 2019,” says CLIMIT special advisor Åse Slagtern. “This also highlights the significance of this CLIMIT project could have for the waste management industry all over the world. Opportunities are there.”

Decisions based on research experience

After the end of three years of research, the project has resulted in increased expertise for all project partners in what is an immature capture technology. For the owner of the plant, the project provides a good foundation for making evidence-based decisions about the opportunities and potential for using oxy-fuel capture technology at the future Waste-to-Energy plant at Haraldrud.

The CLIMIT programme wants to be a part of the green transition, and in the Research Council of Norway’s call for project proposals in spring 2022, carbon capture and storage was one of several priority areas. There were a total of 23 applications in the area of carbon capture, transport and storage applying for a combined NOK 228 million in support from the Research Council of Norway.

A tough competition

At CLIMIT’s programme board meeting on 21 June 2022, six applications were selected with a total of NOK 60 million in support. There was tough competition for funding, and only one in four applications received support. Many great applications unfortunately had to be rejected because there were not sufficient funds to support all good applications.

Applications were reviewed according normal Research Council of Norway procedures, and external experts played a key role in assessing the quality of each application. CLIMIT’s programme board has the final say on which are the best applications to support.

The new projects

The six new projects will be displayed in the Research Council of Norway’s project bank as soon as contracts are signed. This is expected to take place in autumn 2022. A short description of the new projects is provided below.

Project number	Project title	Project owner
36222	Advanced energy recovery and CO2 capture systems for a decarbonised ferroalloy industry	SINTEF Energy
336266	Data and models to optimize maritime CO2 transport and offshore injection	SINTEF Energy
336294	Expansion of Resources for CO2 Storage on the Horda Platform	NORCE
336355	Primary Flow Reference for CCS	SINTEF Energy
336357	Future Drinking Water Levels of Nitrosamines and Nitramines near a CO2 Capture Plant	NIVA
336939	Advancing LedaFlow for robust and accurate multiphase flow simulations to enable transport and injection of CO2	LedaFlow Technologies DA

 

The Research Council of Norway has high expectations for the new projects. Results from the projects will be important for building carbon capture, transport and storage at a large scale. The projects may result in cost reductions, a key factor if carbon capture and storage is to be a central part of the green transition. The new projects will also be useful in the benefits realisation that politicians are preparing for in relation to Longship, the Norwegian full-scale CO₂ capture and storage (CCS) project.

One group, for example, is examining how exporting CO₂ to other countries impacts support for CCS and which factors impact public perceptions of CCS projects during construction/planning.

How society responds to CCS

There are three different projects, but what they all have in common is that they look at how society responds to CCS. What is needed in Europe for acceptance of CCS and the market adaptations needed for the roll out of production of blue hydrogen. “We look forward to presenting the results from these three exciting projects,” says Åse Slagtern, special advisor at CLIMIT R&D who promises that we will hear more from these projects in the future.

The three projects

 

Developing value chains for CO₂ storage and blue hydrogen in Europe

• The Ragnar Frisch Centre for Economic Research
• NOK 5.2 million

In order to develop markets for carbon storage and hydrogen, an age-old problem needs to solved: A blue hydrogen producer is not willing to invest in facilities before it has good reason to believe that a carbon storage site is under development. At the same time, an operator considering building a carbon storage facility is unlikely to want to invest before it is reasonably sure that it will get customers.

This project will analyse the development of value chains for carbon storage and hydrogen in Europe. The most important aspects of the project are:

• Assessing the demand for carbon storage, particularly the social acceptance and economic factors for demand for storage services
• Studying the competition between carbon storage in Europe when important factors such as economies of scale and industrial learning are taken into consideration
• Developing business models that ensure an efficient distribution of risk between private and public stakeholders
• Studying the competition between blue and green hydrogen and the competition between conventional energy, CCS-based energy, and renewable energy, and discussing the design of instruments to ensure the socioeconomically favourable development of a value chain for carbon storage and hydrogen
• Assessing how the Norwegian Northern Lights project can change market structures.

As a part of the project one PhD and one postdoctoral will be recruited.

 

Does the nationality of CO₂ matter? Public perceptions of a Northern European market for CO₂ storage (CCSMARKET)

• NORCE Norwegian Research Centre AS
• NOK 5.2 million

CCSMARKET analyses what people in Norway, Germany, Denmark, the Netherlands and the United Kingdom think about carbon capture and storage (CCS).  A lack of public support, particularly relating to land-based underground storage, has previously been a barrier to establishing CCS in Europe.

Through this project, they hope to discover how exporting CO₂ to other countries impacts support for CCS in the exporting nations and how this affects support for CCS in importing nations. NORCE will use comparative surveys to investigate this. The purpose of this is to identify and quantify factors that impact public perceptions of CCS projects during construction/planning. The aim is to improve understanding of mechanisms that impact attitudes towards CCS.

 

Socio-technical drivers, opportunities, and challenges for large-scale CCUS

• SINTEF AS
• NOK 10, 7 million

This project is based on the multidisciplinary sustainability transitions research field and hopes to understand the innovation processes around the establishment of CCS. The project will analyse innovation linked to the entire value chain for CCS and CCU (carbon capture and utilisation) and will look at how strategies and business models for key industrial operators and regional industrial transformation processes contribute to the development of CCUS and vice versa.

CaptureX focuses on the importance of legitimisation processes (including acceptance) and policy developments for the development and spread of CCUS.

The CaptureX project is being carried out by a leading group of social science energy researchers in Norway (SINTEF Digital, NTNU KULT, UiO TIK) and Sweden (Chalmers) and involves CCS experts from SINTEF Energy.

As a part of the project two postdoctorals will be recruited.

Global aviation issues and Covid infections meant that many were unable to attend. It still managed three successful days through a hybrid solution.

Three CSLF projects

The Carbon Sequestration Leadership Forum Technical Group, CSLF PIRT (Project Interaction and Review Team) had received applications from three projects that wanted to be recognised as CSLF projects. These were:

• CO₂Ment from Canada
• Northern Lights from Norway
• Porthos from the Netherlands

The criteria for being recognised as a CSLF project include the project bringing something new to the implementation of carbon capture and storage. All these new projects do, and all three were recognised. These projects will bring lots of new knowledge that will benefit both countries and stakeholders going forwards.

Awards were handed out during the meeting to three CSLF projects that have contributed significantly to the implementation of CCS so far:

• Technology Center Mongstad (TCM) which was CSLF-recognised in London in 2009
• Boundary Dam which was CSLF-recognised in Beijing in 2011
• Tomakomai which was CSLF-recognised in Tokyo in 2016

Two panel discussions were held later in the meeting. The first was led by Bruno Gerrits from Global CCSI and primarily focused on transfer of experience from large-scale pilot projects. Boundary Dam, Tomakomai, Northern Lights, the Heidelberg Materials project and Alberta Carbon Trunk Line had representatives. An important takeaway was the significance of projects being open and reporting on issues that arose and how they were resolved.

The second panel discussion was led by Tim Dixon from IEAGHG and focused on how research and testing infrastructure could contribute to standardisation and scale-up. The International Test Center Network, TCM, CO₂Geonet, Otway Research Facility and ECCSEL took part in the discussion. The discussion pointed to the significance of this sort of infrastructure in reducing the risk associated with scale-up and in contributing to standardisation. All participants underlined the challenges in getting funding for infrastructure and operations.

CEMCCUS Initiative, Mission Innovation CDR and the Clean Energy Transition Partnership (CETP) also provided brief updates. All of these initiatives have good synergy with CSLF.

All presentations at the meeting will be made available on the CSLF website

A CDR workshop was held on 28 June

The workshop provided an overview of the policy framework for CDR from the IPCC, the United State’s CDR efforts and the status of Mission Innovation CDR. Furthermore, an introduction to CDR technologies was given with more details on DAC (Direct Air Capture), mineralisation and BECCS (Bioenergy with CCS). Afterwards, several technology suppliers and users spoke about their technologies, before rounding off with a panel discussion on CDR and what the right way to register carbon removal might be. The importance of life-cycle assessments at a system level was brought up. The meeting closed with group work to identify barriers and drivers for CDR.

The IEAGHG will publish a report that summarises the key points from the workshop.

Furthermore, presentations from the CDR workshop will also be made available on the CSLF website 2022 Technical Group Mid-Year Meeting | CSLForum.

Participants were also able to visit Northern Lights on 29 June.

International synergies

As soon as we return from the summer break, we will start planning next year’s CLIMIT SUMMIT. We hope to see you there, so be sure to save the date in your calendar: 7-9 February. CLIMIT’s programming committee agreed at its meeting in June to organise a summit in 2023, and the secretariat has been tasked with planning this event which will take place over two days from midday to midday.

In 2023 this will take place at the Bølgen Cultural Centre in Larvik. The 2023 edition of the event will focus on the realisation of gains and experiences around the interface of project Longship with ACT, CETP, Mission Innovation, IEAGHG, and CSLF. This will allow us to create positive synergies between a range of CLIMIT projects and international activities. Naturally, CLIMIT’s project portfolio will also be showcased as a key element of the summit. We look forward to seeing you all in Larvik in February 2023.

Please feel free to get in touch with us and our project manager Liv Lønne Dille if you are thinking about tying an event into the wider summit.

About the call for proposals

The company has two refineries on the west coast of Sweden, one in Lysekil and one in Gothenburg. Preem is exploring the possibility of fullscale CCS using storage in Norway.

Implementation at existing facilities

The primary goal of the project was to research the possibility of implementing fullscale carbon capture from Preem’s hydrogen production unit (HPU) at Preemraff Lysekil in Sweden and to produce liquid CO₂ for permanent storage underneath the west coast of Norway in accordance with specifications and requirements set out in the Longship initiative.

SINTEF Energi AS, Equinor Energy AS, Aker Carbon Capture AS and Chalmers University of Technology have all been involved in the project in one way or another, and publications have been and continue to be released and a number of webinars relating to the project have also been held.

Activities completed during the project

• Carbon capture demonstration at the hydrogen production unit at the Preem refinery in Lysekil. The production unit is based on steam methane reforming (SMR). For the demonstration, pilot-scale carbon absorption was tested through the use of Aker Carbon Capture’s mobile testing unit (MTU).
• Extrapolation of the results of the demonstration so that they can be understood in connection with the work on the fullscale implementation of carbon capture from HPUs and other major emissions sources at the Lysekil refinery and Preem’s refinery in Gothenburg. 
• In-depth examination of opportunities around energy efficiency in the CCS value chain, including recycling and the use of residual heat at the refinery which can be used to run the process for solvent recovery as well as using alternative solvents for carbon capture. 
• Evaluation of the technical feasibility and cost to the CCS value chain, including carbon capture and transport by ship to storage facilities off the west coast of Norway. 
• Research into relevant legal and regulatory aspects of carbon transport and storage across borders and national goals for emissions reductions in Norway and Sweden. 

Two publications are publicly available:

• D5.1 Preem CCS – Synthesis of main project findings and insights
  • Available online in the Chalmers archive: https://research.chalmers.se/publication/528685

• D4.2 Legal and regulatory framework for Swedish/Norwegian CCS cooperation
  • Available online in the SINTEF archive: https://hdl.handle.net/11250/2984155

Currently, the company is heading a feasibility study on how CO₂ from incineration can be captured, transported and stored.

Statkraft’s plant at Heimdal incinerate waste from the entire mid-Norway. The district heating plant sends heated water in pipelines to housing associations and institutions such as St. Olav’s Hospital, the Norwegian University of Science and Technology, Lerkendal Stadium and the Nidaros Cathedral.

These days, Statkraft is conducting a feasibility study in cooperation with national and international players, the industrial cluster CCS Mid-Norway, Trondheim Port Authority and Trondheim Municipality.

«The content of the feasibility study is three-fold,» explains Statkraft’s Bjørn Hølaas, director of CCS. «In the technical part, we are evaluating different technologies for capture, and intermediate and permanent storage. In the commercial part, we are analysing how the framework of incentives, markets, sources of income, taxes, etc., is developing. Finally, we are investigating how the growth of the circular economy will reduce fossil content in waste – mainly plastic – since this will cut fossil emissions.»

Mature technology

Statkraft has chosen to divide the feasibility study in two parts. In one part, a technical basic concept was developed in cooperation with Rambøll Denmark, Project Invest and TCM. The second part encompasses verification, improvement and optimisation of the basic concept together with suppliers.

«We have focused on establishing a robust concept,» says Bjørn Hølaas. «Since we selected a standard monoethanolamine (MEA) solution, we don’t have to consider patent issues. The amine technology has been widely proven and is comprehensively documented. We wanted to ensure that the concept was buildable, so that the work in part two – verification, improvement and optimizing the concept – ran smoother.

The value of cooperation

One of the main challenges of implementing CCS at the district heating plant at Heimdal, concerns transport and intermediate storage. Still, almost 40 percent of the costs of the basic concept is related to transport, intermediate and permanent storage. And this cost must be reduced.

Whether Statkraft chooses to hook up to the Northern Lights infrastructure – or opts for a different alternative – the company will need an intermediate storage for captured CO₂. The basic concept includes an intermediate storage of 3600 tonnes. Which is about half a ship load from Northern Lights.

«As a consequence, we have sought to collaborate with other players in CCS Mid-Norway. If we can work together to identify solutions for transport and intermediate storage in Trøndelag – and this way reduce costs for all of us – implementing solutions for transport and intermediate storage, will be a realistic option,» says Bjørn Hølaas.

CCS Mid-Norway springs from the Mid-Norway industrial cluster. Companies such as Franzefoss, Elkem Thamshavn, Wacker and Equinor at Tjeldbergodden, participate in this initiative, seeking to develop a regional infrastructure for transport and intermediate storage of CO₂ from the production processes.

Regulatory framework in process

An important part of the feasibility study is dedicated to developing a comprehensive overview of the commercial framework for CO₂. There is great interest in EU’s certification scheme for handling CO₂, which will be announced towards the end of 2022.

«EU’s new directive will give us important instructions on how we shall monitor, and report on, critical parameters along the value chain. It’s also interesting to observe how Sweden, Denmark, the Netherlands and Great Britain have organized their CO₂ handling regulation regimes.»

Voluntary marketplaces for CO₂ quotas and biogenic emissions – like Puro Earth and other arenas – are growing steadily, and will eventually play a decisive role.

«In Statkraft, we see the importance of partnering up with key players – in a broad cooperation with relevant authorities – in order to promote a sustainable framework,» says Bjørn Hølaas.

A robust regulatory framework ensures a level of predictability that is necessary for the industry in order to implement CCS technology. But more is needed from governmental authorities.

«Putting CCS technology to use, is crucial in order to learn from practical and operational experience – which, in turn, translates into cost reductions. In commercial terms, it will take some time before CO₂ capture will be economically sustainable, so it’s imperative that governments contribute with public funds.»

CLIMIT support creates results

So, what role has CLIMIT’s played?

«The financial support is definitively crucial. But maybe even more important is it that CLIMIT supports such a wide array of CCS projects. The accumulated knowledge that is channelled through CLIMIT, is as valuable as the support we receive for our own projects. And it’s a great advantage that CLIMIT emphasizes the external communication of project results. Moreover, I believe that for those of us who work in the different industrial companies, public funding through CLIMIT gives the internal projects we propose higher legitimacy,» says Bjørn Hølaas.

The project draws on a goal-oriented, systematic effort to build competence in the field of carbon capture.

The process industry must play a central role in the struggle to achieve the overarching goal of the Paris agreement: Limiting long-term temperature increase to well below 2℃. A shift from fossil fuels to green energy, will not alone suffice to cut emissions. In fact, many industrial companies produce more CO₂ than finished product. Therefore, high costs become the bottle neck for implementing carbon capture plants. This means that the research community and the industry together must find pragmatic solutions that the industry can adopt rapidly.   

And one of the drivers behind CCS in the Norweigan process industry is Elkem, one of the world’s leading provider of advanced silicon–based materials.

A necessary collaboration

Bringing about substantial changes requires knowledge in new areas.

«Elkem’s voyage started around 2017,» says Elkem’s climate director Trond Sæterstad. «At that time, Elkem joined CO₂ Hub Nord.» This initiative for collaboration on CCS and infrastructure, consists of industrial players in Mo i Rana industrial park and companies further north, as well as in the county of Trøndelag.

Since Elkem has production plants at several locations in Norway, the company has been a proactive contributor in an array of CCUS industrial collaborations – such as the Eyde cluster, the Mid-Norway cluster, in addition to CO₂ Hub Nord. The latter is currently starting up tests of CO₂ capture from the flue gases of Elkem and SMA Mineral.

In these cluster projects – all of which receives financial support from CLIMIT – the member companies are investigating solutions for CCS, local infrastructure and logistics.

«It’s a huge advantage for adjacent industry to collaborate in order to establish sound solutions for local infrastructure and logistics. That’s why the cluster projects are so important. This way, it’s possible to source large volumes of CO₂ for storage, and the companies can share costs related to infrastructure and transport,» says CLIMIT’s Jørild Svalestuen.

A learning process

Elkem has focused on several areas.

Between 2015 and 2019, the company participated in the CLIMIT-supported project CO2stCAP, a cooperation between Norwegian and Swedish industrial companies and research communities. The purpose was to analyze processes and identify factors that drive down costs in carbon capture projects.

Elkem also participated in Process 21, a cooperation and knowledge sharing initiative between Norwegian companies. The forum directed attention toward identifying solutions to reduce the total emission of the national process industry. The steering committee was headed by Håvard Moe, Elkem’s senior vice president for technology.

In 2021, Elkem launched the Global Climate Roadmap. This strategy defines CCS as central to reaching the company’s goal of sustainable production of materials.

A study of opportunities

Through this multi-faceted work, Elkem acquired the competence required to take the next step. The company was ready to investigate practical, operational carbon capture solutions for its smelter plants. In parallel with CO₂ Hub Nord, the company executed a feasibility study, which was completed in 2021.

The purpose of the study was to devise a business model for the installation of CCS technology at Elkem’s smelter plants. The model evaluates all critical factors related to operating such technology. By closely considering a diverse set of operating conditions – such as technical status – at the smelter plants, the model calculates with a high level of precision, what it will cost to implement capture installations at the local plants.

Two solvent technologies – from Saipem and Aker Carbon Capture – were evaluated according to the needs of the smelter plants. How could the technologies be adapted to the operational environments? How well suited were they to extract CO₂ from the flue gas emitted during the production process?

«It was an incredibly exiting exercise,» says Ragnhild Jensen, project director in Elkem. «We needed to learn more about the practical aspects of CCS. What do we have to do on our side of the interface? How must the plants prepare and facilitate the installation of the new technology? What happens in the capture process? What’s the output? And – not least – what is required in terms of energy integration?»

Elkem brought in Norsk Energy, a consultancy specializing in environmentally friendly and safe use of energy, in order to evaluate the energy integration aspects of the technology from the two suppliers.

«The project gave us a better understanding of the efficiency of capture, the technical requirements that the vendors specified for Elkem’s flue gas, and the output of the technologies,» says Ragnhild Jensen.

The result was a significantly improved process design for the implementation of CCS technology.

 

One step further

The knowhow that Elkem acquired through meticulous preparations, has been essential in order to carry out comprehensive testing at the smelter plants.

«The natural next step for us, is to verify the technology at our plants,» says Trond Sæterstad, Elkem’s climate director. «Before we can make an investment decision, the capture installations must be tested and evaluated in an operational setting.»

Now, the ferrosilicon producer Elkem is starting up – under the auspices of the CCUS industrial consortium CO₂ Hub Nord – the first pilot project of its kind. During six months, the company will operate a mobile test unit from Aker Carbon Capture – a full-scale capture plant in miniature.

The capture technology from Aker Carbon Capture will be tested on separate flue gases from Elkem Rana and SMA Mineral. However, the project will also test CO₂-cleaning from jointly sourced flue gas from the two producers.

The last alternative opens up for exciting prospects. The option of gathering streams of flue gas from several producers, will translate into significant cost reduction for each industrial company.

And this is critical. Because it’s imperative to reduce costs.
