Italy: Buzzi Unicem has signed an agreement with Italgas to collaborate on the development of power to gas plants for implementation in combination with carbon capture systems. Their research will assess the possibility of producing and using synthetic methane obtained from the combination of green hydrogen from power to gas plants with captured CO₂.

Buzzi Unicem’s group technical director at Luigi Buzzi said "We are very interested in the opportunity to collaborate with Italgas as an experienced partner to develop a project that is fully integrated into our industrial investment plan aimed at identifying technologies for capturing and reusing the CO₂ released by our plants, in line with the roadmaps defined by industry associations.” He added “Our aim is to responsibly contribute to containing climate change by developing CO₂ capture technologies and identifying the best solutions for its reuse. We are currently experimenting with calcium looping technology for capturing the carbon dioxide released by the production process at our plant in Vernasca, Piacenza. Thanks to the EU Horizon 2020 Cleanker project, it will be possible to assess the technical and economic sustainability of this technology and estimate the changes to the plant and the investments required to adopt this process in existing cement plants.”

Australia: RMIT University in Melbourne, Victoria, has developed a new method of carbon capture, called the bubble column method. The method uses liquid gallium at 100 – 120°C, through which flue gas is bubbled. This activates the CO₂, leading to oxidation of the metal. The captured carbon accumulates on the surface of the pool.

Gallium is a by-product of bauxite and zinc ores mining. The United States Geological Service (USGS) has estimated its global reserves in these ores alone as 1Mt.

Project co-lead Torben Daeneke said “Turning CO₂ into a solid avoids potential issues of leakage and locks it away securely and indefinitely. Because our process does not use very high temperatures, it would be feasible to power the reaction with renewable energy.” He added “Ideally the carbon we make could be turned into a value-added product, contributing to the circular economy and enabling the carbon capture and storage (CCS) technology to pay for itself over time.”

The Australian Government plans to invest US$719m in low emissions technologies by 2050 under its Net Zero Plan.

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.

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."

Australia: Boral says that its emissions reduction targets have been approved by the Science Based Targets Initiative (SBTi) as being consistent with the levels required to meet the goals of the Paris Agreement. Boral released its targets in August 2021 when it said it intends to reach net-zero emissions by no later than 2050. It subsequently joined the SBTi’s Business Ambition for 1.5°C and the United Nations Framework Convention on Climate Change Race to Zero campaign.

The Australia-based building materials company plans to reduce its Scope One and Two emissions by 46% by 2030. It also plans to decrease its relevant Scope Three emissions per tonne of cementitious materials by 22%. It intends to do this by: transitioning to 100% renewable electricity by 2025 and increasing alternative fuels usage at its Berrima plant kiln; growing the proportion of revenue from its lower carbon concrete product range and optimising the efficiency of its cement plant; reducing transport emissions in its own and contractor fleet; prioritising lower carbon intensity suppliers; and exploring and testing emerging carbon capture use and storage technologies.

Boral’s Chief Finance and Strategy Officer, Tino La Spina, said “Boral is determined to become a leading innovator in sustainability through decarbonisation of cement and concrete and increasing our contribution to a more circular economy” He added “We continue to support our customers in their transition to net zero, broadening our range of high performing lower carbon concrete products to cater for all building and infrastructure applications, and offering Climate Active−certified net carbon neutral concrete.”

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.
