Cemex turns flue gases into carbon nanomaterials

26 April 2022

Mexico: Cemex has reported its successful completion of laboratory tests aimed at converting CO2 emitted by cement kilns into carbon nanomaterials. The producer said that it was able to turn 50% of available carbon in a flue gas stream into nanomaterials. Possible industrial uses for carbon nanomaterials include in building materials, biomedicines, electronics and agriculture. Cemex says that its next step will be to scale the technology for a cement plant pilot study.

CEO Fernando Gonzalez said “This breakthrough technology is significant for Cemex, not only because it offers the potential to commercialise carbon emissions, but because it demonstrates the value of our Smart Innovation platform. The path to carbon neutrality will be built with innovation, and we remain committed to being at the forefront in developing new circular technologies and processes.”

Rohrdorf cement plant to host pilot CO2 separation plant study

07 March 2022

Germany: Rohrdorfer and Austria-based Andritz Group are in the process of installing a 2t/day CO2 separation plant on the roof of the former’s Rohrdorf cement plant in Bavaria. The pilot plant will capture CO2 from the plant’s emissions for use by the regional chemicals industry. The Ingenieur newspaper has reported that it will cost Euro3m and is scheduled for commissioning before June 2022. It is the first installation of its kind at a German cement plant.

Rohrdorfer’s plant and process engineering manager Helmut Leibinger said “We must begin to see CO2 as a product of value rather than a problem. With CO2 as a carbon source, Germany can protect the climate and at the same time become less dependent on oil and natural gas. In addition, value creation and jobs will remain in the country.”

Cemex and Synhelion produce clinker using solar heat

03 February 2022

Spain: Cemex’s Mósteles clinker pilot batch production unit at IMDEA Energy Institute in Madrid Autonomous Community has produced its first batch of solar-heated clinker. The unit uses Switzerland-based Synhelion solar radiation technology. The technology uses a solar receiver and gaseous heat transfer fluid to heat raw materials.

Cemex chief executive officer Fernando Gonzalez said “The production of the first solar clinker is an exciting milestone for this transformational technology. It is proof of our commitment to deliver tangible outcomes through innovation to achieve our goal of delivering only net-zero CO2 concrete by 2050.” He concluded “Cemex is building a better future, and that future must be sustainable.”

LafargeHolcim España launches CCSU joint venture with Carbon Clean and Sistemas de Calor

06 January 2022

Spain: LafargeHolcim España has announced the launch of a joint venture called ECCO2 with Carbon Clean and Sistemas de Calor. The joint venture will develop carbon capture technology for use at the producer’s Carboneras cement plant in Almería. It will then seek to market captured CO2 from the plant for use as a gas in local agricultural greenhouses. When commissioned in early 2023, the carbon capture system will have the capacity to capture 10% of the Carboneras plant’s CO2 emissions.

ACC and Ambuja Cements to develop calcined clay cements with Indian Institute of Technology Delhi

29 November 2021

India: ACC and Ambuja Cements have partnered with the Indian Institute of Technology Delhi (IITD) to develop a range of calcined clay cements with 50% lower CO2 emissions than Ordinary Portland Cement (OPC). The collaboration will vary clinker, calcined clay and limestone levels in calcined clay cements in order to ascertain their effects on its performance. France-based Holcim Innovation Centre will fund the research.

Holcim India chief executive officer and managing director Neeraj Akhoury said "Through our extensive research and development setup, we consistently strive to develop new low-CO2 materials for the construction industry. Calcined clay cement is one such avenue to make a significant quantitative difference in the industry and further accelerate our sustainability drive. Our academic partnership with IITD is a big step towards building a greener future and we are excited to collaborate with the best minds in the country."

The producers have previously partnered with the Indian Institute of Technology Madras (IITM) to study low-CO2 binders with alternative reinforcements and with the Indian Institute of Technology Hyderabad (IITH) to develop smart sensing technology for continuous on-site strength evaluation of a concrete structure.

Vicat project at Montalieu-Vercieu cement plant to test hydrogen production technology from Genvia

19 November 2021

France: Vicat plans to test hydrogen electrolysis technology provided by Genvia for a pilot project at its Montalieu-Vercieu cement plant. Genvia made the announcement following a tour of its facilities by President Emmanuel Macron. It will be working with Vicat, Hynamics, a subsidiary of EDF group, and EDF Energy on the initiative. Other pilot projects have been announced with steel producers ArcelorMittal and Ugitech.

Genvia is a hydrogen production joint venture between French Alternative Energies and the Atomic Energy Commission (CEA), Schlumberger New Energy, VINCI Construction, Vicat Group and the Occitanie Region. It is developing and promoting solid oxide technology to enable industrial decarbonisation through hydrogen production, energy storage and fuel applications at scale.

Cool Planet Technologies and Hereon to supply carbon capture system for Holcim Deutschland’s Höver cement plant

09 November 2021

Germany: Cool Planet Technologies and Hereon have signed a memorandum of understanding with Holcim Deutschland to deliver a carbon capture system for a carbon capture and storage (CCS) trial at the producer’s Höver cement plant in Lower Saxony. Cool Planet Technologies will install their system, which is based on Hereon’s PolyActive membrane technology. The system will have a capture capacity of 5600t/yr and operate from early 2022 to early-mid-2023. If successful, two subsequent expansions will increase the system’s capacity to 170,000t/yr, commencing operation in 2024, and 1.3Mt/yr, commencing in 2026.

The suppliers say that their membrane-based capture system is capable of reducing the energy intensity and eliminating the need for other chemical inputs in CCS.
