Building of the Largest Chemical Looping Combustion (CLC) Facility to Drive down the Cost of Carbon Capture

Paris/Deyang City (China), February 2, 2022 – CHEERS, a Sino-European consortium of leading researchers and manufacturers, has announced the construction of the world’s largest demonstration unit for Chemical Looping Combustion (CLC). This new stage will bring the project to a pre-industrial scale and confirm the potential of this key technology in driving down the cost of carbon capture and promoting the decarbonization of industry. Today the project reached a new milestone when TotalEnergies, Dongfang Boiler Group Co. (DBC), Tsinghua University and IFP Energies Nouvelles made the decision to build the 3MWth demonstration unit, with the potential to deliver 4-5 MWth.

Lowering the cost of carbon capture in power generation

CLC is an oxy-combustion technology used to convert biomass and fossil fuels in order to obtain a flow of pure CO2 suitable for low-cost capture.  This integrated CO2 capture solution minimizes the use of costly gas separation processes like those retrofitted on existing combustion facilities. CLC generates heat that can be used to produce carbon-neutral electricity and/or steam.

“This unique project paves the way for the decarbonization of industries that currently generate a significant proportion of global carbon emissions. It could open the door to more cost-effective biomass and fossil fuel emission reductions at facilities around the world,” said project leader Dr. Nils Erland L. Haugen from SINTEF.

“Decarbonizing energy production is a major challenge. The TotalEnergies R&D teams carried out the research and design phases that enabled the CHEERS project partners to take this step and green-light the construction of a pre-industrial unit to validate the technical, economic and environmental performance of the CLC technology,” said Philip Llewellyn, Carbon Capture, Utilization and Storage Program Manager, TotalEnergies.

Developing technology from concept to reality

The investment decision marks the transition from the research and design phases to the engineering and construction phases, led by DBC at their technology development site in Deyang, near Chengdu in China.

The test campaign, planned for 2023, will bring the new concept to near-commercial maturity (Technology Readiness Level TRL 7) and form the basis for further upscaling and commercial project development.

The initial investment in the Deyang demonstration unit will total almost €10 million, in addition to the €10 million already invested in the research and development activities.

“The CLC process is the result of 13 years of research conducted by IFPEN and TotalEnergies on a laboratory scale and on a 10 KW pilot unit in IFPEN’s laboratories. The building of a demonstrator on a pre-industrial scale is therefore a very important step that will allow us to verify the performance of this CO2 capture technology and to prepare its implementation in power plants and biomass plants in particular,” said Florence Delprat-Jannaud, CO2 Coordinator, IFPEN.

The CHEERS project launches next phase of industrial scale plant design

 

Carbon Capture and Storage (CCS) is a key technology to achieve greenhouse gas emission reduction targets and mitigate global warming. CO2 capture is the building block of CCS with considerable impact on the downstream transportation and storage stages.

Chemical looping combustion (CLC) is an innovative combustion technology with inherent CO2 separation. A metal oxide is used to transfer oxygen from the air reactor to the fuel reactor, where fuel is burned without direct contact with air. The resulting CO2 from the combustion part of the process is not diluted with nitrogen from the air, hence, no additional CO2 separation step is required. This is the main feature of the CLC process, which permits inherent CO2 separation with a high degree of energy efficiency improvement and competitive capture cost.

Captured CO2 must satisfy specifications depending on its form of transport and final destination, which may be storage or utilisation. This means that, due to downstream requirements, treatment and conditioning are critical steps in the CO2 capture process.

Various contaminants may be present in the captured stream, such as NOx and SOx, depending on the type and quality of the fuel. Fuels such as natural gas and some biomass feedstocks need little post treatment while heavy fuels, such as petcoke, need NOx and SOx removal units. These technologies are currently deployed at large scale in industrial applications. However, CO2 captured in a CLC plant has some differences compared to conventional flue gasses, such as absence of free N2, lack of or low O2 content and high steam concentration. This makes the flue gas from a CLC plant lower in volume but higher in concentration of contaminants, which results in some specific challenges to be overcome.

TOTAL has launched a development and engineering feasibility study together with HAMON on the CO2 treatment topic. HAMON is a technology provider on flue gas treatment with extensive experience on industries such as power, refining and petrochemicals. This study is focussed on the treatment of CO2 captured from a petcoke-fired CLC plant. Regarding the typical content of this fuel, a complete flue gas treatment scheme is needed including dust particle removal, DeNOx and DeSOx. This will be further completed by drying and compression steps to deliver a CO2 that is compliant with specifications for CO2-EOR usage.

CHEERS project aims at demonstration of CLC technology at 3 MWth scale including feasibility and techno-economic studies for preparation of industrial demonstration. This study permits evaluation of the next CLC development phase, which will be an industrial demonstration unit at a capacity of 30 – 60 MWth. The aim is that success at this stage will result in wide industrial deployment of the CLC technology to produce steam for industrial applications or electrical power with zero or negative CO2 emission and improved energy efficiency. The CHEERS consortium includes Bellona, Dongfang Boiler Group Co. Ltd (DBC), IFP Energies nouvelles (IFPEN), SINTEF Energy Research, SINTEF Industry, TOTAL, Tsinghua University, Silesian University and Zhejiang University.

The CHEERS project is financed partially by the EU’s Horizon 2020 Research and Innovation Programme and the Chinese Ministry of Science and Technology, with financial and industrial support from project partners.

The CHEERS team adds a new peer-reviewed publication to its growing list

The CHEERS project has achieved several research objectives in its quest to design, build and operate what will be the world’s largest demonstration CLC facility.

One of its areas of research has focused on understanding how the particles of fuel and oxygen carriers evolve as they chemically react, change size and density as they pass through the various chambers of the complete CLC system.

The CHEERS team is proud to announce publication of research results in the peer-reviewed journal Combustion and Flame, where the drag force acting on a fully reacting fuel particle is studied and explained in great detail.

This is essential knowledge for an optimal system design, which involves finding the right balance between flow rates, reactor height and diameter, as well as a long list of operating parameters and modes.

One step closer to industrializing a new carbon-free energy production technology

The front-end engineering design (FEED) phase of the Chinese-European Emission-Reducing Solutions (CHEERS) project has now started – a major milestone in this project. When finished, it will be the world’s largest chemical looping combustion (CLC) demonstration plant.

The project is the last step before an industry-wide deployment of CLC technology. CLC generates steam for industrial applications or electrical power, without CO2 emissions thanks to its built-in ability to separate CO2. This means CLC can produce energy with zero carbon content. In addition, It can produce energy with negative carbon content when using feedstocks such as biomass. In this case, CLC enables the indirect capture of CO2 from the atmosphere, and the reduction of greenhouse gas content to the atmosphere.

The demonstration plant – to be built in China – will test the second-generation CLC technology at a capacity of 3MW and will be the largest of its kind using this new fuel-conversion technology in an operational environment.

A 3-D engineering rendering of the planned demonstration plant

The ground-breaking concept has the potential to increase the efficiency of CO2 capture significantly, compared to existing carbon capture technologies and can remove up to 96 per cent of combustion-related CO2. The project offers a viable path to retrofit industrial combustion processes and is a major step towards the large-scale decarbonization of the refining, chemical and power industries.

Managed by TOTAL, the FEED was awarded to Worley, who will carry out the services from its Belgium and China offices. Once completed, the FEED results will be handed over to Dongfang Boiler Group Co Ltd, who will manage the detailed engineering, procurement and construction (EPC) of the plant.

The CHEERS project is financed partially by the EU’s Horizon 2020 Research and Innovation Programme and the Chinese Ministry of Science and Technology, with financial and industrial support from TOTAL, Dongfang Boiler Group Co Ltd, and other project partners.

How to design the flow inside a CLC installation

The CHEERS project continues its design and verification work based on the cold flow rig described in a previous post. In this newly produced video of the cold flow rig, more detail and description are provided on the subsystems and components involved.

A very important intermediate step is to build a visualization rig that looks very much like a working CLC plant, but does not use fuel. Instead, it circulates the particles used to transfer oxygen to the fuel in a nitrogen-free environment.

The cold flow rig (sometimes called a cold flow mock-up) was designed, built and installed by our CHEERS partners in Europe and China. This video highlights the special design details implemented on the cold flow rig for European design specifications.

If you are interested in the technical details behind this, then you can read our CHEERS researchers recently submitted article to the peer-reviewed journal Energy&Fuels. This article has been accepted for publication after final formatting for the printed version of the journal.

But if you would simply like to watch the new video with more complete description of the cold flow rig in action, here it comes.

Special thanks goes to our CHEERS project partner IFP Energies nouvelles for producing and editing this new video.

Chemical Looping Combustion: how it works in a new video

The global warming challenge is one of the greatest innovation opportunities going forward. One strategy is to re-invent combustion from scratch to promote more efficient CO2 capture. A very promising such solution is Chemical Looping Combustion (CLC).

The Cheers project is developing Chemical Looping Combustion (CLC) to the next level. CLC is an energy production technology leveraging inherent, built-in, CO2 capture. This reduces the need for investment in dedicated CO2 separation from low-concentration flue gases. It also reduces operational costs because it uses less energy in its inherent CO2 separation process.

Designing a full-scale CLC plant is still a work in progress. The current fleet of CLC test rigs are made and used for basic research and development. These are now ready to be scaled up to dimensions suitable for commercial application.

The CHEERS project has produced the design basis of a 3 MWth demonstration CLC facility with systems that will allow researchers to understand how to make it even better in the next version. This design basis is now being converted to a Front End Engineering and Design (FEED) by a world-renowned engineering contractor. This will be announced in a post coming soon.

The animation below shows how the system works, and what makes CLC a great candidate for re-inventing combustion.

CHEERS acknowledges generous support from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764697 and the China MOST program.
