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.”

Thailand: Siam Cement Group (SCG) plans to spend US$2bn towards meeting its CO₂ reduction target by 2030. The industrial group and cement producer intends to reduce its emissions by 20% by the end of the decade, according to the Bangkok Post newspaper. Chief executive officer Roongrote Rangsiyopash, said that the investment will be made from 2022 to 2030 and that it follows the United Nation’s Sustainable Development Goals (SDG), the Thai government's bio, circular and green (BCG) economic model and environmental, social and governance standards (ESG). After 2030 the group has a net zero goal for 2050.

In cement production the SCG wants to increase its rate of alternative fuels such as biomass and refuse-derived fuel. It also wants to invest in carbon capture utilisation and storage, use electric vehicles and use artificial intelligence systems in energy management. The group plans to reduce coal usage at its cement plants in Thailand, Vietnam, Laos, Cambodia and Indonesia by 50% in 2022. It also plans to use more electricity generated by renewable energy for its factories.

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.

Mexico/UK: Cemex has partnered with UK-based carbon capture equipment supplier Carbon8 Systems to evaluate possible uses of the supplier’s Accelerated Carbonation Technology (ACT) in the group’s cement production. Operators can use the equipment to produce carbon-infused sustainable materials from thermal residues. Cemex says that one possible application will be in the production of supplementary cementitious materials. Under the partnership, Carbon8 Systems will evaluate a range of Cemex’s byproducts for possible use, beginning at its Rüdersdorf cement plant in Germany and Rugby cement plant in the UK. It will also evaluate the suitability of alternative lightweight aggregates produced using ACT for sale in each market.

Executive vice president sustainability, commercial, and operations development Juan Romero said "This initiative with Carbon8 Systems is another example of the work we are doing with partners across industries, academia, and startups to tap into the latest innovation and disruptive technologies to achieve our ambition of delivering net-zero CO2 concrete globally to all of our customers."

Japan: Taiheiyo Cement and the University of Tokyo have patented a carbon capture system based on a new carbon fixation method. The method passes CO₂-bearing gas over 40mm granules of a hardened cementitious material at 75 - 100°C. The granules then fix the CO₂ from the stream to themselves, for utilisation or storage.

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.

US: LafargeHolcim US has revealed more information about a commercial-scale carbon-capture study based at its integrated Ste. Genevieve cement plant in Missouri. The project aims to deliver a front-end engineering design (FEED) study for a carbon capture retrofit that can separate up to 95% of CO₂ emissions at the plant. The captured CO₂ will be ‘pipeline ready’ for geological storage and analysis of the project socio-economic impact will also be part of the study. The US Department of Energy’s National Energy Technology Laboratory awarded US$4m to the Prairie Research Institute at the University of Illinois to work on the project in early October 2021. LafargeHolcim and Air Liquide are also making cost share contributions.

The design will use Air Liquide’s Crycocap FG system at the cement plant. LafargeHolcim US says that it combines pressure swing adsorption capabilities with cryogenic refrigeration technologies to achieve high CO₂ capture rates with high CO₂ purity rates. Notably, for a carbon capture project, the Ste. Genevieve plant has one of the largest single clinker kilns in the world.

Germany: Cemex Zement’s Rüdersdorf, Brandenburg, cement plant is to host a new 100t/day carbon capture installation. Cemex Zement will collaborate with UK-based Carbon Clean on a front-end engineering and design (FEED) study for the project. The system will combine captured CO₂ with sustainably sourced hydrogen in order to produce green synthetic hydrocarbons. The partners aim to increase the system’s CO₂ capture capacity to 300t/day by 2026, before finally scaling it up to 2000t/day.

Europe, Middle East, Africa and Asia regional president Sergio Menendez said “This project with Carbon Clean is the latest development in Cemex’s plan to achieve carbon neutrality at the Rüdersdorf cement plant by 2030, through our pioneering carbon neutral alliance with expert industrial consortiums. Carbon capture will play a fundamental role in the efforts to succeed at this goal and ensure our operations are more sustainable.”
