We have actively participated in various R&D collaborative efforts with different sectors to develop technologies to capture, utilize, or store carbon, as well as other carbon reduction technologies. Some of these projects include:
■ SOLPART (EU funded project with Grant Agreement (GA) n°: 654663) intends to pilot a high-temperature (950°C) solar process in sustainable operation suitable for the calcination of cement raw materials.
■ EPOS’ (EU funded project with GA n°: 679386) main objective is to enable cross-sector industrial symbiosis and to provide a wide range of technological and organizational options for making business and operations more efficient, cost-effective, competitive, and sustainable.
■ GENESIS (EU funded project with GA n°: 760899) explores the use of metallic organic frameworks to entrap CO2 from flue gas. The CO2 can then be stored, but in the GENESIS context, it will be fed into an algae bioreactor.
■ DESTINY (EU funded project with GA n°: 820783) aims to employ microwave energy in clay calcination for use in low clinker cement. The target is to demonstrate the concept through a microwave-powered plant targeted to a production rate of 20 kg of calcined clay per hour.
■ eCOCO2 (EU funded project with GA n°: 838077) aims to set up a CO2 capture and conversion process using renewable electricity and water steam to directly produce fuels, targeting a CO2 per-pass conversion of greater than 85%, energy efficiency of more than 85%, and net specific demand of less than 6 MWh/t CO2. The demonstration phase intends to produce over 250 g of fuel per day.
The Carbon Capture, Utilization, and Storage (CCUS) technology is a key lever to deliver on our 2050 Ambition.
Since 2002, CEMEX has been studying CCUS in collaboration with other companies, international organizations, and academic institutions. Currently, CEMEX is actively participating in close to 30 research projects aimed at contributing to carbon reduction and mitigation including accelerating CCUS implementation on an industrial scale.
The LEILAC 2 project is funded by the European Union’s Horizon 2020 research and innovation program. The project team comprises leading industrial, technology, and research & development partners. CEMEX had a very active participation in LEILAC 1, working with the partners to develop the novel direct separation of process carbon emissions derived from the clinker/cement manufacture. The highly concentrated CO2 resulting from the technology can then be easily handled via capture and/or storage. Process emissions are roughly 60% of the direct CO2 emissions from cement production. Thus, this technology can contribute significantly to the decarbonization of the whole sector.
CEMEX is enthusiastic and determined to continue its contributions to the project by bringing expertise, experience, and key resources. For example, simulation experts undertook significant modeling of the CO2 reactor tube to obtain the required capture rate. CEMEX’s technical team also tested novel designs for the CO2 reactor tube, given its deep understanding of the cement production process and how the technology can be implemented most effectively.
CEMEX decided to participate in LEILAC 2 pursuing and contributing to the technology’s development utilizing its gasification process’s expertise. It is also leveraging its skills in alternative fuel consumption and computational fluid dynamic simulation design, aiming to succeed in the second stage of the LEILAC project.
“Our participation in the LEILAC 2 project is another example of our continued efforts to deliver net-zero CO2 concrete products globally by 2050,” said Davide Zampini, Head of Global R&D. “We are determined to have a significant direct involvement in research and development efforts pursuing high impact technologies in carbon capture, use, and storage.“
