CCS - Carbon Capture and Storage
Due to the long term growth of the global economy and the development in many markets of the world, the demand for cement and concrete construction materials will continue to increase significantly. Within this context, the technical potential to reduce overall CO2 emissions from cement manufacturing with today’s technology is limited and definitely less than what abatement strategies currently being discussed demand and what stakeholders expect. The capture of carbon dioxide and its geological storage, often referred to as “carbon capture and storage” (CCS) is seen today as an emerging technology capable of reducing CO2 emissions significantly.
According to different abatement scenarios and the International Energy Agency’s Roadmap, the cement industry is expected to contribute to CO2 mitigation globally by a set of different measures among which CCS plays a key role. Against this background ECRA has been working on carbon capture research since 2007 in a long-term project designed to examine the capture of carbon dioxide as a prerequisite for a safe geological storage of CO2.
ECRA’s goal is to examine the technical and economic feasibility of this technology as a potential application in the cement industry. ECRA lays strong emphasis on the global perspective of its research and also on sustainability. This implies that not only CO2 emissions as such, but also the huge energy demand for operating CCS plants will be taken into account. ECRA’s CCS project comprises five phases. Phases I, II and III have been completed and phase IV is currently underway, in which the possibility of initiating an industrial-scale oxyfuel kiln is being examined.
ECRA Academic Chair at the University of Mons
In 2013 ECRA established an academic chair entitled “CO2 to Energy: Carbon Capture in Cement Production and its Re-use” at the University of Mons (UMONS) in Belgium within the UMONS Research Institute for Energy.The main objective of the chair is to create a centre of scientific expertise in the specific field of carbon capture and re-use in cement production, and to promote research and innovation. It supports research activities by financing fellowships for postdoctoral researchers, PhD students and undergraduate students. A particular research focus is placed on:
- Post-combustion, partial oxyfuel and total oxyfuel CO2 capture applied in the cement industry
- Flue gas treatment in CO2 capture (in particular de- NOx and de-SOx) that can be applied by absorption or adsorption; this includes not only oxyfuel combustion but also micro-pilot studies and projects on capture technologies as post-combustion
- The reuse of CO2 which can be achieved by various processes which convert CO2 into methanol or other compounds while benefitting from renewable electricity.
Cooperation with Norcem Brevik
For several years ECRA has been cooperating with the Norcem Brevik cement plant in Norway where different post-capture technology providers have already been testing their technology under realistic conditions The Norcem project consists of four individual technologies:
- Solid sorbent technology by RTI
- Amine technology by Aker Solutions
- Membrane technologies by a consortium under the lead of the Norwegian University of Science and Technology
- Carbonate looping by Alstom Power
Cooperation with CEMCAP
CEMCAP is a project funded by Horizon 2020 addressing CO2 capture from cement production by the demonstration of different CO2 capture technologies in an industrially relevant environment (TRL 6) based on the previous work of ECRA and Norcem. CO2 capture technologies with the greatest potential to be retrofitted to existing cement plants will be identified and a techno-economic decision basis formulated. The project duration is from 2015 to 2018. ECRA is involved as an industrial advisory group to give guidance to the research consortium and communicate the results within the European cement industry.
2nd ECRA/CEMCAP Workshop held in November 2017
On 6-7 November 2017 the second of three ECRA/CEMCAP workshops took place in Duesseldorf on the topic of “Carbon Capture Technologies in the Cement Industry”. The workshop began with a poster session the evening before and was attended by over 80 participants from the cement industry, industry associations, research institutes, NGOs, universities and technology providers. All presentations from the workshop and the posters from the poster session can be downloaded here. Details of the date and location of the third workshop, which is scheduled to take place in October 2018, will be made available soon.
CSI/ECRA Technology Papers
The Cement Sustainability Initiative (CSI) is a global effort by 23 major cement producers with operations in more than 100 countries who believe there is a strong business case for the pursuit of sustainable development.
In June 2017 CSI and ECRA released their new "CSI/ECRA Technology Papers 2017" to update the perspective of available technologies for CO2 abatement and energy efficiency in the cement sector. The publication analyses existing and future technologies with potential to increase energy efficiency and decrease CO2 emissions in cement production and is an update of its former version from 2009.
The decision for the further development of the technology papers in 2017 was taken by CSI in the light of the discussion and ratification of the Paris Agreement of the United Nations Framework Convention on Climate Change (UNFCCC) for the reduction of global warming and a pathway towards low greenhouse gas emissions and climate-resilient development.
CSI assigned the project to ECRA, which has close links with key stakeholders of the cement industry and technology providers among its members and provided its competency in the field of cement technology. It is intended that the CSI/ECRA technology papers 2017 can now again serve as an important reference document for the development of further technology roadmaps in the cement sector.
