China/Uzbekistan: Anhui Conch has released an update on some of its major development projects. Its new plant at Tashkent in Uzbekistan has an investment of around US$260m. The company reports that 30,000m² of equipment and materials have arrived, the rotary kiln supporting wheels have been hoisted in place, the main body installation of the coal mill has been completed, the structure of the dormitory building has been capped and the main factory area has begun to take shape. It is also building a plant at Brakbash District in Andijan State. Civil engineering and main engineering construction are reportedly underway. The company also has a third cement plant in the country. So far the group has built over 10 cement plants outside of China.

In China, Anhui Conch is building a CO₂ energy storage demonstration project at its Baimashan cement plant in Wuhu, Anhui province. The group says that, once complete, the project will be the world's first commercial demonstration project of a CO₂ energy storage system. It says that during the low power consumption period, the excess power will be used to compress CO₂ at normal temperature and pressure into a liquid. The heat energy generated during the compression process will be stored. The stored heat energy will then be used to heat the liquid CO₂ back into a gas, driving the turbine to generate electricity, reducing the cost of electricity. The demonstration project has an area of 40,000m².

The cement producer says it is working towards a model of ‘one base and five industries’ where cement production links to other industries such as new energy, new materials, environmental protection, the digital economy and the promotion of international trade.

Germany: The Science-Based Targets Initiative (SBTi) has validated Heidelberg Materials' new 2030 CO2 reduction targets. The targets have a base year of 2020 and conform to a 1.5°C climate change framework. Per tonne of cementitious material, the producer is now committed to reducing its Scope 1 CO2 emissions by 24%, its Scope 2 CO2 emissions by 65% and its Scope 3 emissions by 25%.

Heidelberg Materials' chief sustainability officer Nicola Kimm said “As reflected in our updated Sustainability Commitments 2030, climate action is a crucial element of Heidelberg Materials’ sustainability strategy. The SBTi validation shows that our sustainability agenda not only includes the most ambitious reduction target in the cement industry – but also a realistic, measurable plan in line with the 1.5°C scenario. We follow a clear, science-based approach, reducing our carbon footprint through the levers of product and process innovation and industrial-scale carbon capture, utilisation and storage. By closing the carbon and material loops, we will lead the sustainable transformation of our sector.”

In 2019, Heidelberg Materials became the first cement company to secure SBTi validation for its emissions reduction commitments.

Spain: Cemex España will install a carbon capture system at its Alicante cement plant in Valencia, as part of its efforts to make the unit a 'benchmark pioneer low-CO₂' cement plant. The producer holds a contract with ET Fuels for the supply of 45,000t/yr of CO₂ captured at the facility for methanol production.

Chief executive officer Fernando González said “Our goal of reaching net-zero CO₂ emissions is achievable and will be driven by collaboration and innovation. Our decarbonisation roadmap includes reducing emissions to the lowest possible level through proven levers such as clinker substitution and alternative fuels. New levers, such as rapidly developing CCUS initiatives, must effectively tackle the remaining CO₂ emissions to hit our ambitious 2050 objectives.”

Germany: Heidelberg Materials' sales increased by 13% year-on-year to Euro21.1bn in 2022 from Euro18.7bn in 2021. This was despite a 6.1% drop in cement and clinker volumes, to 119Mt from 127Mt. Heidelberg Materials' cement and clinker volumes fell by 10% in Western and Southern Europe, by 7.8% in Northern and Eastern Europe-Central Asia, by 14% in North America, by 1.3% in Africa-Eastern Mediterranean Basin and by under 1% in Asia-Pacific. The group's materials costs rose by 23% to Euro21.4bn from Euro18.8bn. Meanwhile, its profit dropped by 9.4% to Euro1.72bn from Euro1.9bn.

Chief executive officer Dominik von Achten said "It’s evident that we can only be profitable in the long term by shaping our future as a company in a climate-compatible way, further reducing the footprint of our products and closing material loops. We are making good strides in all areas. Compared with the previous year, we were able to reduce our specific net CO₂ emissions by another 2% in 2022. Our carbon capture, utilisation and storage projects launched worldwide are progressing favourably. At our CCS project in Brevik, Norway, we are well on track with the construction of the world's first CO₂ capture plant in our industry, and we look forward to commissioning in 2024." Von Achten continued "We have made a good start to 2023. The fourth quarter showed that we have laid a good foundation for the development in this year. Volatility on energy and raw material markets remains high, but the current easing in energy prices is giving us some breathing room. On the demand side, government infrastructure plans should compensate for the decline in private housing construction. We are optimistic about the further course of the year.”

Germany: Austria-based Rohrdorfer has started up an amine-based carbon capture system at its Rohrdorf cement plant in Bavaria. The producer plans to ultimately expand the system up to a capture capacity of 1500t/day. The inauguration follows a successful continuous trial of the technology since August 2022, excluding a regular kiln maintenance period over winter. Austria-based Andritz designed the system specifically for the Rohrdorf cement plant. It yields CO₂ that is suitable for numerous applications, including in food and beverages and in intermediate products in pharmaceuticals production. The Rohrdorf cement plant also hosts a formic acid plant which uses captured CO₂.

Rohrdorfer aims to achieve carbon-neutral cement production by 2038. Alongside production-related optimisations, the producer plans to realise its aim through a future expansion to the Rohrdorfer plant’s carbon capture system and the implementation of a further carbon capture upgrade at a second cement plant in Austria.

Greece/Italy: The Hercules international research project, which has 27 partners from 10 countries, has been launched officially at Milan Polytechnic, Italy. Hercules, an acronym for ‘Heroes in Southern Europe to decarbonise industry with CCUS’ will test new solutions in the CO₂ capture, transport, use and storage value chain and transform them into a scalable industrial process. Buzzi Unicem and Titan Group are two of the 27 partners, alongside waste-to-energy players and developers of advanced CO₂ capture equipment. This includes ‘calcium looping’ technology from Finnish Sumitomo SHI FW and cryogenic purification technology from TPI in Italy.

A part of the pure CO₂ flow will be destined for use in production processes. These include the production of new cementitious materials that could replace conventional concrete, as well as uses in the technical gas sector. Hercules will also investigate the transport of CO₂ from the industrial capture sites to geological storage sites at Ravenna (Eni) and Prinos (Energean). The gas will be handled by Air Liquide and Titan Cement.

Belgium: Cembureau, the European cement association, has warned against a proposed 2041 phase-out date for industrial CO₂ in the Commission draft Delegated Act on renewable fuels of non-biological origin (RFNBOs). The European Commission’s (EC) draft Delegated Act on the greenhouse gas saving criteria for RFNBOs sets the rules under which such fuels can qualify as sustainable. The European Commission considers that CO₂ from industrial sources should not be allowed for the production of synthetic fuels as of 2041, as this would go against the objective of carbon neutrality by 2050.

Koen Coppenholle, the chief executive officer of Cembureau, said “By proposing an arbitrary deadline on the use of industrial CO₂, the EC severely restricts the deployment of carbon capture and utilisation (CCU) in the cement sector.” He continued “We regret that this phase-out date was established without a thorough impact assessment. This risks negatively impacting several on-going carbon capture projects in the European Union (EU), at a time of a global race for green investments.” Coppenholle also called for a “real, thorough debate on CO₂ utilisation” to ensure that EU policies support CCU and the deployment of CO₂ transport infrastructure and storage.

The association is objecting against this proposal because in its view: manufacturing synthetic fuels using industrial CO₂ make a “decisive” contribution to climate mitigation in the short to medium term; no impact assessment has been presented by the EC; the delegated act threatens the viability of existing CCU projects in the cement sector, which require a payback time of 30 - 35 years; and the Delegated Act does not recognise the reality of industrial installations like cement plants, which are faced with unavoidable CO₂ emissions, and may not have access to CO₂ geological storage sites.

The Delegated Act will be passed to the European Parliament and Council for further scrutiny until April 2023 whereupon they will either accept to reject the proposals. The scrutiny period can be extended to June 2023 at the request of either body.

US: The Department of Energy’s (DOE) Carbon Storage Assurance Facility Enterprise (CarbonSAFE) initiative has awarded funding of US$8.9m to Heidelberg Materials North America to study the subsurface geology for suitability for the storage of carbon dioxide at the Mitchell integrated cement plant in Indiana. The proposed project will geologically characterise several prospective reservoirs under the Mitchell plant for storage of more than 50Mt of CO₂ over a 30-year timeframe.

The award, which is managed by the National Energy Technology Laboratory, will be issued to the Illinois State Geological Survey at the University of Illinois (ISGS) as the prime contractor, with the company acting as a technical and industrial partner. Heidelberg Materials is contributing about US$1.5m in funding while ISGS will be contributing approximately US$0.6m for a project total of US$11.1m. The funding was part of a DOE initiative that generated nearly US$125m in funding for 10 projects to characterise suitability for carbon storage across the US.

Heidelberg Materials’ Mitchell cement plant is being upgraded with a new production line. Full production on the new line is anticipated to start in early 2023.

Europe: The European cement association, Cembureau, has 'welcomed the objectives' of the European Commission's new Green Deal industrial plan. The Green Deal attempts to create a predictable and simplified regulatory environment in which to scale up the production and implementation of net-zero CO₂ technologies.

Cembureau also issued its advise for a successful Green Deal implementation. The association said that the framework must match the US Inflation Reduction Act in its provision of tax rebates and other incentives. It said that the plan must establish stable renewable energy prices and rapid permit procedures, with a focus on deployment of renewables at industrial sites. It also called for funding under the plan to finance the development of infrastructure for CO₂ transport and storage.

Japan: Mitsubishi Heavy Industries (MHI) has won an Award for Excellence at the 41st Nikkei Excellent Products and Services Awards for its carbon capture system. It was among eight industrial products to win the award for the year. The panel of judges selected MHI's system for its compact and versatile module configuration, which shortens installation and transport times.

MHI's model has been in industrial operation since June 2022, when MHI inaugurated its first system at Taihei Dengyo Kaisha's Seifu Shinto biomass power plant. The technology is now in operation or under implementation at cement plants in Japan and overseas. Most recently, MHI secured a carbon capture contract with a UK cement plant, Hanson's Padeswood plant, in mid-December 2022.
