US: The California Department of Transportation (CalTrans) has approved the use of Portland limestone cement (PLC) in its projects. The California Nevada Cement Association (CNCA) says that the move has the potential to eliminate 25,500t/yr of CO₂ emissions.

The CNCA plans to achieve cement and concrete carbon neutrality by 2045 through three priority actions. These are investment in promising and critical long-term technologies (crucially carbon capture, utilisation and storage (CCUS) technologies), increased alternative fuel (AF) substitution and the acceptance of PLC for CalTrans projects. Thus, the latest CalTrans decision marks the establishment of one pillar of the CNCA’s ambitious plan for net zero.

Spain: HeidelbergCement is starting the Neuclicem carbon capture use and storage (CCUS) project at its integrated Arrigorriaga plant near Bilbao. Local electricity company Volbas and the Tecnalia Research & Innovation centre are participating in the initiative. The project intends to look at a process based on the mineralisation of alkaline waste, such as residual construction waste or steel slag, by accelerated carbonation using CO₂ from the flue gas at the plant. The resulting materials will then be used as additives in cement production or to reduce the use of clinker. The scheme will study its viability of the process on an industrial scale.

The Neuclicem project has an estimated duration of 14 months. Its results are intended to prepare the way for scaling up to a subsequent industrial prototype. The project is partially financed by Ihobe, an environmental management division of the regional Basque government.

Japan: Mitsubishi Heavy Industries Engineering has won the Ministry of Economy, Trade and Industry’s highest prize for contributions to industrial decarbonisation, the Minister’s Award, for its development and commercialisation of its CO₂ capture system. The system is based on KS-21 solvent technology, developed in partnership with Kansai Electric Power, and the company’s Advanced KM CDR Process capture model. Mitsubishi Heavy Industries Engineering has successfully supported cement industry customers in implementing the system.

China: Nanjing Kisen International Engineering has secured a collaboration agreement with Canada-based Delta CleanTech for the implementation of the latter’s carbon capture and storage (CCS) systems at two China National Building Material (CNBM) cement plants. SCMP News has reported that there is a one-time licencing fee - which is not paid by Nanjing Kisen International Engineering but is traditionally paid by the CO₂ capture plant customer - of 4.5 - 5% of capital costs. Installations cost upward of US$40m, depending on capacity.

There are currently 40 operational or upcoming CCS installations nationally with a total capture capacity of 3Mt/yr, chiefly in the oil, coal chemicals and energy sectors.The Chinese Academy of Environmental Planning has forecast that China’s cement industry CCS demand will reach 200Mt/yr by 2060. Delta CleanTech president Jeff Allison said that current challenges for Chinese cement producers seeking to reduce their CO₂ emissions include difficulties disposing of captured CO₂ and a lack of rewards and penalties around emissions control beyond the basic national efficiency requirements.

Nanjing Kisen International Engineering previously launched its first 155kg/day pilot CCS study in partnership with the Canada-based International CCS Knowledge Centre in July 2021.

Canada: Lehigh Cement and Enbridge have announced a memorandum of understanding to collaborate on carbon storage for the integrated Edmonton cement plant in Alberta. Captured emissions will be transported via pipeline and sequestered by Enbridge. Lehigh Cement says it is developing North America’s first full-scale carbon capture, utilisation and storage (CCUS) unit for the cement industry at its Edmonton plant, with the goal of capturing approximately 0.78Mt/yr of CO₂.

Pipeline company Enbridge intends to apply to develop an open access carbon hub in the Wabamun area, west of Edmonton in conjunction with Lehigh Cement and Capital Power, as part of the Government of Alberta's Request for Full Project Proposals process. Once complete the Open Access Wabamun Carbon Hub would be among the largest integrated CCUS projects in the world. Subject to the award of carbon sequestration rights and regulatory approvals, the project could be in service as early as 2025.

Norway: Germany-based MAN Energy is supplying a compressor system for a carbon capture and storage (CCS) unit being built at Norcem’s Brevik cement plant. The scope of supply includes an RG 63-7 type electrically-powered compressor train. The steam generators cool the CO₂ mixture between the compressor stages and generate steam that is in turn used for capture. The project will be the first to use the ‘Carbon Capture Heat Recovery’ technology (CCWHR) developed by MAN and Aker Carbon Capture. This new process allows the heat emerging from the compressor system to be recovered and used as steam to meet approximately one third of the total heat demand from the Aker Carbon Capture plant. Consequently, MAN says that the system solution demands less energy compared with conventional carbon-capture technologies.

Alexander Sobolyev, Head of Standardisation & Solutions at MAN Energy Solutions, said: "As part of the Norcem project, the digital-twin-based engineering approach of MAN Energy Solutions has led to concrete optimisations. The dynamic process simulation showed that originally planned system components, including heating, valves and additional pipes for safe plant operation, were not required. The time taken for a cold start of the plant can thus be reduced from around 12 hours to 20 minutes – an important characteristic as quick-start capability is always a central criterion for renewable energies."

US: Performance materials and technologies conglomerate Honeywell has entered into a collaboration with the University of Texas at Austin for the development of carbon capture systems. Honeywell has obtained a licence to use the university’s proprietary advanced solvent technology. The University of Texas at Austin will provide consulting services for the company as it seeks to develop a carbon capture system for industrial implementation using the technology. Honeywell will target ‘hard-to-abate’ CO₂ emitting industries such as cement to which to supply its system.

University of Texas at Austin McKetta Department of Chemical Engineering professor and Texas Carbon Management Program (TxCMP) lead Gary Rochelle said “We are thrilled that our decades of research has led to carbon capture technology that can significantly reduce carbon emissions. The licensing agreement with Honeywell enables us to commercially scale this in ways that can make major contributions toward zero emissions efforts to address global warming and to reduce pollutants in surrounding communities.”

Japan: Taiheiyo Cement is among 13 participant companies whose proposed carbon capture, utilisation and storage (CCUS) demonstration hub has received approval to proceed with funding from the Japan Ministry of the Environment. Nikkei Business Trends News has reported that Toshiba Energy Systems and Solutions, Uyeno Transtech, JGC, Chiyoda, Taisei Corporation, the University of Tokyo, Kyushu University, Japan NUS, the National Institute of Advanced Industrial Science and Technology and QJ Science also collaborated in the development of the CCUS system. The trial will begin in early 2022 and conclude in the 2025 financial year.

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.

India: Dalmia Cement plans for 100% of its cement to be low carbon by 2031. The company has a US$405m carbon capture and utilisation (CCU) investment plan to help it to realise its goal. It will also undertake carbon offsetting measures.

Business Line News has reported that the company plans to spend US$1.35bn to increase its installed cement capacity by 52% to 50Mt/yr from 33Mt/yr before the 2024 financial year.
