Crown Prince Haakon is known for his keen interest in business development and innovation. Particularly on environmental issues and the green transition. He believes that technical innovation plays a crucial role in addressing global challenges. Recently, he spent a day in Bergen, where offshore wind was on the agenda. During his visit, he toured to the Bergen Offshore Wind Research Centre. Located at the University of Bergen and participated in a seminar for industry players in the offshore wind sector. Furthermore, HRH Crown Prince Haakon is scheduled to make an official visit to the West Coast of the USA from 15-18 April 2024, aimed at promoting business cooperation in the areas of green transition and digitalization.

Cooperation with the USA

At TCM, the US-based carbon capture company ION Clean Energy (video) has successfully completed its second test campaign for the company’s amine-based capture technology, achieving excellent results link to web case. ION also conducted test at Mongstad in 2016, being the first of a number of US companies to use TCM with partial funding from the US Department of Energy (DoE). In addition, InnoSepra is currently testing its technology in the TCM’s area dedicated to new technologies.

Our collaboration with the US government and technology developers has been mutually beneficial,” states Muhammad Ismail Shah. “We are excited to showcase how our contributions have supported the development of technologies now being deployed in large-scale carbon capture and storage (CCS) projects in the US.

International Opportunities through Testing at TCM

Furthermore, , several other major technology players have tested at TCM, including Longship, which utilizes Aker Carbon Capture’s technology developed at TCM. All seven major technology suppliers that have engaged with TCM have subsequently initiated projects in various locations worldwide.

Among other distinguished guests expected during the Crown Prince’s visit are Liv Signe Navarsete, Governor of Vestland County, Astrid Bergmål, State Secretary at the Ministry of Energy, Sara Hamre Sekkingstad, Mayor of Alver Municipality, Morten Sognnes, Mayor of Austrheim Municipality, and Kaare Songstad, Commissioner of the Western Police District.

TCM’s CEO to mayors in Nordhordland: “Yes, we can!”

– The world desperately needs cost-effective CO2 capture technologies. Can we in little Norway play a role in providing them? Can we contribute to solving the climate crisis? Yes, we can!

“Yes, we can!” said CEO Muhammad Ismail Shah.

TCM’s managing director, Muhammad Ismail Shah, used Barack Obama’s campaign slogan “Yes, we can”. When he presented TCM’s activities at a meeting with the mayors of Alver, Austrheim, Gulen, Masfjorden and Modalen on Wednesday 21 February. Shah pointed out that the International Energy Agency (IEA) estimates that by 2050. 1.7 billion tonnes of CO2 will need to be removed directly from the air and water. And 6 billion tonnes through conventional carbon capture and storage to avoid global warming. The capture facilities that have come online to date will capture around 50 million tonnes.

The way forward

– In other words, we have a long way to go. But Norway is leading the way with the Longship project,” says Shah, “We look forward to Heidelberg Materials’s capture facility at Brevik becoming operational with a target of 400,000 tonnes of CO2 per year. In addition Aker Carbon Capture’s capture technology has been tested here at TCM. With the transport to the receiving facility in Øygarden. After that the storage under the seabed in the North Sea, we are up and running. Longship and Northern Lights are just the beginning of a new and important industrial chapter in Norway. Internationally, a number of promising CCS initiatives are in the pipeline, not least in the US – stimulated by President Biden’s mammoth green transition programme, the Inflation Reduction Act.

More than 20 test campaigns

Since its establishment in 2012, TCM has carried out more than 20 test campaigns on various carbon capture technologies. In December last year, an agreement was signed under which the Norwegian state reduced its stake in the company to 34 per cent, while Equinor, Shell and TotalEnergies increased their stakes to 22 per cent each. “The owners have collectively challenged me and all of my employees to ensure that in 2024 and 2025, we position the company for a future where operations will be self-sustaining,” said Muhammad Ismail Shah. “The programme we are implementing to achieve this goal is called TCM 2.0. Can we succeed? “Yes, we can!”

The TCM CEO thanked the mayors present for the support and interest the company has received in the region over the years. They reciprocated by congratulating Shah and his staff on the new operating agreement and wishing them well for the future. They also heard interesting presentations from the new director of Equinor Mongstad, Bernt E. Tysseland, and the project manager for Greenspot Mongstad, Einar Våge, who outlined the plans for the greening of Mongstad.

InnoSepra advancing with efficient carbon capture solutions

InnoSepra, led by Dr. Ravi Jain, is dedicated to developing clean energy technologies tailored for diverse end-users.

Their expertise encompasses various carbon capture methods. Including direct air capture, and capture from industrial sources with varying CO2 concentrations. Additionally, InnoSepra pioneers’ innovative solutions in flue gas purification. And CO2 compression, applicable across a spectrum of carbon capture technologies.

Following testing of their first-generation post combustion carbon capture technology at an NRG facility in Delaware, InnoSepra has embarked on testing its second-generation technology at TCM at the “Site for Emerging technologies”. With partial funding from the US Department of Energy (DoE).

“Why did you choose to come all the way to Norway and Mongstad to test your technology?”

“We selected TCM due to its outstanding facilities and infrastructure offerings. Moreover, TCM provides an invaluable opportunity for independent validation of various technologies. A crucial aspect for end users.”

Dr. Ravi Jain founded InnoSepra in 2007 and serves as the company’s President. He holds a Ph.D. in Chemical Engineering from the University of Michigan. Prior to this role, Dr. Jain held positions as Section Director and Technology Fellow at the BOC Group.

Great results for InnoSepra

On your website, it is mentioned that The second generation InnoSepra Post Combustion Capture Technology can reduce the absolute parasitic power for CO2 capture to below 1.8 GJ/tonne. This implies that the technology currently being tested at TCM has the capability to lower the energy consumption for capturing CO2 to below 1.8 GJ/tonne of CO2. Additionally, you state that The technology has the potential to reduce power loss due to steam extraction by more than 70% compared to MEA.

Could you please confirm whether the test results obtained so far have validated this assertion? “We have made significant progress toward achieving this goal. Although not yet with our preferred mode of regeneration. Through air regeneration, we believe we can attain the parasitic power target of below 1.8 GJ/tonne of CO2 at temperatures below 110°C. While also meeting the expected CO2 capacities. Implementing our preferred mode of regeneration presented challenges. But we are on the verge of success, and we hope to demonstrate regeneration with our preferred operational mode before the project’s conclusion.”

“Your test campaign started in November and will continue until March. Followed by the analysis and documentation of the results. What will be the next steps towards commercialization and market introduction for carbon capture?

“We need to do one more scale-up, from 10 to 25 times of this test, to be able to offer the technology for large-scale CO2 capture. For smaller plants such as lime and hydrogen, less than 500 tons a day, we can combine the results from the first and second-generation capture technologies along with other technologies to offer very cost-effective capture solutions within two years. Additionally, we aim to expand the scale of our flue gas purification technology by 50 to 100 times, making it an integral component of a solvent-based capture solution. Industries we are engaging with include lime, cement, and hydrogen. In some cases, significant additional scaling may not be required to provide a cost-effective capture solution.”

«Thank you, and good luck with the final stages of the test campaign at TCM.»

TCM plays a key role in the AURORA project

TCM actively participates in a joint European project to develop CESAR1 as an non-proprietary solvent for carbon capture in the industry.

About AURORA

AURORA is a collaborative project funded by the European Union’s HORIZON EUROPE research and innovation program. Its primary objective is to optimize and qualify the open, non-proprietary CESAR1 solvent-based carbon capture technology for commercial deployment. The project commenced in January 2023, with a focus on demonstrating the technology at Technology Readiness Levels (TRL) 7–8 in at least three CO2-intensive industries: refining, cement, and materials recycling. These sectors have been chosen due to the absence of viable alternatives toward achieving climate neutrality.

The AURORA team.

Strong industry participation

In addition to TCM, the AURORA consortium includes eight members from various industry and research institutions across Europe. In early January, the project members convened in Cambridge, UK, to engage in stimulating brainstorming sessions focused on technical and innovative ideas.

Koteswara Rao Putta serves as the Technical Services Lead & Research Project Coordinator at TCM, representing the company in the consortium overseeing the project. He mentioned, “TCM actively participates in several work packages related to model development, validation, and technology assessments. We are also making planning and preparations for a solvent testing at TCM.”

«What are the main challenges for the commercial deployment of the CESAR1 solvent?»

«The commercial deployment of the CESAR1 solvent faces several challenges. Mainly of an operational nature. In this regard, TCM contributes valuable experiences from our test of CESAR1 conducted three years ago. The project aims to tackle these challenges. By demonstrating the technology’s viability in CO2-intensive industries.»

“The CESAR1 solvent was named after the FP7 CESAR project (2008-2011). In which the aqueous mixture of 2-Amino-2-Methyl-1-Propanol (AMP) and piperazine (PZ) was first studied. Because the CESAR1 solvent repeatedly outperformed the reference MEA solvent technology in pilot tests. Also CESAR1 has good energy performance, low degradation rates. And can achieve very high capture rates and is easier to use in flexible modes. Like most solvent technologies, CESAR1 has the advantage of being easily adaptable to almost any flue gas source.” (Soure: https://aurora-heu.eu/the-project/#cesar-solvent)

«What will be the next steps taken in the AURORA project?»

«The project will continue to focus on model development, validation, and technology assessments. Solvent testing at the TCM plant will be a critical milestone in assessing the technology’s readiness for commercial deployment in different industries.»

TCM report; Corrosion and materials

TCM has learned that attention must be paid to all parts of the capture process. Something that is easy to forget is the effect of capture chemicals and CO2 itself on various materials of construction.

Large material costs

It is not easy to think of all the possible scenarios. For what could happen in a CO2 capture plant. At TCM it has been experienced that capture chemicals, byproducts and CO2 can degrade materials used in the plant. And if you don’t take this into account. It can be very expensive.

TCM’s extensive experience in capture testing with real capture solvents and flue gasses has enhanced understanding of corrosion and material selection. Use of corrosion coupons at several locations throughout the TCM amine plant allows many materials to be tested simultaneously across a range of process conditions.

Through more than 10 years of operation. TCM have seen in various test campaigns that the plant reacts differently. And therefore it can be cost saving to talk to us at TCM if you are planning a capture plant for CO2. – We are happy to share our experiences with handling CO2 in a capture plant, adds our managing director Ismail Shah.

Three reports have been published under corrosion and materials

  • Assessment of Erosion-Corrosion as Possible Failure Mechanism of Reboiler at Technology Center Mongstad (2022)
  • Assessment of Material Selection for the CO2 Absorption Process with Aqueous MEA Solution based on Results from Corrosion Monitoring at Technology Center Mongstad (2019)
  • Results from MEA amine plant corrosion processes at the CO2 Technology Center Mongstad (2016)

What can happen?

During a test campaign here at TCM using monoethanolamine (MEA). A failure occurred in the reboiler of the amine plant which was caused by a serious damage to the plate heat exchanger (made of AISI 316L stainless steel). The result was a significant loss of material (approx. 200-250 µm reduction in thickness). As well as a leak between the solvent and the heat exchanger. A detailed investigation including laboratory studies on the effect of chemical additives is summarized in the 2022 publication.

TCM learned that during a test period. Critical things can occur at the plant that can have consequences both for the catching process itself and the surroundings. This shows that it is appropriate to test things on a slightly smaller scale before building a full-scale CCS plant as material selection has a large effect on the risk and cost profile.

From corrosion coupon testing  during an  MEA campaign from 2015, TCM experienced, among other things:

  • The corrosion rate for carbon steel, S235, is calculated to be greater than or equal to 1.4 mm/year.
  • The corrosion rate was well below 0.1 mm/year for alloy 304L, 316L and 22 Cr duplex stainless steel.

Further work on the corrosion topic with the non-proprietary CESAR1 solvent is planned to be published in 2024, with the latest updates available via this website and our social media.

TCM report; CO₂ Capture – Operational and process control

Understanding and control of CO2 capture processes during steady operation, start-ups, shutdowns and load changes is critical to enable large scale deployment and operation of CCS.

Through more than 10 years of technology testing campaigns with 24/7 operation. TCM have developed significant learnings and experience in  this area predominantly on the flexible amine plant but also on other TCM test sites.

Long experience with CO2 capture

TCM has generated over 20,000 hours of test data with the non-proprietary MEA and CESAR1 amine solvents. True investigating and documenting various phenomena in the capture process. A range of solvent systems, flue gas compositions, process parameters, operating strategies and analysis techniques have been tested to enhance understanding, improve performance and reduce risks and costs associated with CO2 capture. 6 different publications have been published. – We are proud of the experience we have gained and see that our test results are now being used by more and more full-scale actors. And we are more than happy to share our expertise, concludes Ismail Shah, managing director.

 

More than 10 years of experience in CO2 capture.

The plant is affected by load changes

The value of having flexible CCS facilities that can handle load changes from power plants becomes greater with a higher proportion of renewables (e.g. solar energy and wind) in the energy supply. Start-up and shutdown cycles of power plants with CCS are becoming increasingly frequent. Which could potentially increase fugitive emissions. While the start-up and shutdown of power plants has been characterized. The effect of start-up and shutdown on CCS plants is still unclear. That is why TCM, together with various partners, has looked at this, among other things.

Quantifying residual CO2 emissions, energy requirements and time requirements at start-up and shutdown in amine-based CO2 capture plants

A series of start-up and shutdown tests were carried out in March, June and November 2020 at the technology centre Mongstad (TCM). In these tests, CESAR-1 was used to capture CO2 from flue gas (~4 mol% CO2) coming out of the natural gas-fired CCGT (combined cycle gas turbine) combined with flue gas from heat and power plant (CHP). These tests provide valuable insight into how key process parameters and operating strategies can help minimize disturbances (e.g. time and energy requirements) and CO2 emissions during startup and shutdown of CO2 capture plants.

Performance improvement can be achieved by:

  • Optimizing the solvent volume
  • The time of power availability
  • Key process parameters such as solvent CO2 load or amine concentration

Source: Evaluating performance during start-up and shut down of the TCM CO2 capture facility (2022)

 

CO2 Product Quality

The quality of the CO2 product stream produced by the capture process, including the levels and types of impurities present. This is an increasingly important topic due to the impact on CO2 transport and storage. This has been reflected in CO2 specifications set by projects such as Northern Lights. In 2018, TCM published a full characterisiation of the CO2 product stream with analysis by Airborne Labs supported by TCM online instrumentation. This also included testing on the effects of solvent degradation and certain process parameters on the quality of the CO2 product stream.
