Systems Change Lab report accuses cement industry of failing to make progress towards 2030 climate change target
28 October 2021World: A Systems Change Lab report on the state of climate change action has warned that the global cement industry is making insufficient progress towards its 2030 climate change targets and that a step-change in action is required. It recorded the carbon intensity of global cement production at 635kgCO2/t in 2018 with the 2030 target of no more than 370kgCO2/t. The rate of change over the previous five years was reported as being 2.9% but an annual rate of change of 22.5% would now be required to meet the 2030 target.
It also noted that emissions intensity from the cement industry had actually increased slightly in recent years. It reached this conclusion by using a different methodology from the Getting the Numbers Right (GNR) project. Instead it estimated the global emissions intensity by using global data on process emissions and energy data from the International Energy Agency and the GNR.
The report said that the cement sector would need to go beyond traditional mitigation options such as improving energy efficiency and switching fuels to meet its climate commitments. However, carbon capture utilisation and/or storage (CCUS) and novel cements were described as costly and immature. In its view, “Decarbonisation in the long term thus will depend on significant investments in research, development, and demonstration, alongside efforts to create a demand for low-carbon cements and policies to support investment in decarbonisation technologies.” It described both strategies as, “not yet fully mature in terms of technology development, costs and scaling.” The ‘critical enablers’ it identified to help the cement sector meet its target included stricter regulations, increased demand for low-carbon cement and investment in pilot and industrial scale projects looking at novel cements.
Overall, the report said that change towards averting climate change across 40 key areas in power generation, buildings, industry, transport, land use, coastal zone management and agriculture was not happening fast enough and that none were on track to meet their respective 2030 targets. Change was happening but not at the required pace. Systems Change Lab is a collaboration between the High-Level Climate Champions, Climate Action Tracker, ClimateWorks Foundation, the Bezos Earth Fund and World Resources Institute.
Argos commits to 29% CO2 emissions reduction by 2030 and carbon neutral concrete by 2050
27 October 2021Colombia: Cementos Argos has announced its new commitment to reduce the CO2 emissionsfrom its cement operations by 29% over a period ending in 2030. The company has additionally committed to producing all of its concrete CO2-neutrally by 2050. It said that its strategy will comprise several carbon mitigation techniques, including maximised alternative fuel (AF) substitution, clinker factor reduction, energy optimisation, clean technology upgrades and a diversification of its range of its cement range to include more sustainable products.
Chief executive officer Juan Calle said "We are determined to face this important challenge and we are convinced that we can build the future we have planned and achieve a more prosperous, inclusive and low-carbon world if we work together with determination to accelerate this transition." He added "We will continue to strive to implement tangible actions, achieve measurable progress each year and deliver information about out opportunities and progress transparently."
Finland: Wärtsilä’s sales fell by 6% year-on-year to Euro3.18bn in the first nine months of 2021 from Euro3.39bn in the corresponding period of 2020. It increased its order intake by 11% to Euro3.58bn from Euro3.24bn. The company’s cash flow from operating activities fell by 12% to Euro360m from Euro407m. It expects that demand for its offering will increase ‘considerably’ year-on-year in the fourth quarter of 2021.
The supplier announced that it will aim to achieve carbon neutral operations and to provide a product portfolio which will be ready for zero carbon fuels by 2030. It published a report entitled Front Loading Net Zero on how production economies can make savings while managing the renewable energy transition. The report concludes that full decarbonisation before 2050 will be financially viable if properly supported by governments and energy companies.
President and CEO Håkan Agnevall said “These new targets demonstrate our commitment to a sustainable future. Our aim is to support our customers on their decarbonisation. Our products, solutions, and services will meet the stringent environmental requirements, and the fuel flexibility and fuel efficiency of the engines powering these sectors are key to enabling the transformation.” Agnevall added “Naturally, we also need to do our part as an organisation and minimise our own environmental footprint.”
China to set cement production energy efficiency benchmark
25 October 2021China: The government plans to implement a benchmark level of energy efficiency for cement plants by 2025 in order to realise its national goal of no CO2 emissions growth by 2030 and carbon neutrality by 2060. Local press has reported that the government has yet to set a specific benchmark for the cement industry. The corresponding figure for aluminium production will be 13,000kWh/t.
UK: The government has awarded funding to the planned HyNet North West low-CO2 industrial cluster. The cluster will reduce industrial CO2 emissions by 10Mt/yr in North Wales and North West England. It includes a planned 800,000t/yr carbon capture installation at Hanson UK’s Padeswood cement plant in Flintshire. The producer is currently carrying out a feasibility study at the plant. Parent company HeidelbergCement said that the project will play a ‘critical role’ in the UK’s transition to net zero CO2 emissions by 2050.
Chair Dominik von Achten called the decision “A well-deserved recognition for the HyNet consortium and our colleagues working on carbon capture and storage (CCS) in the UK as part of this collaborative project. Cutting CO2 emissions is a key priority for us, and we are delighted to add our Padeswood cement works to our growing range of CCS activities, as a key part of our pathway to reaching net zero.”
Germany: Holcim Deutschland has signed a memorandum of understanding with Cool Planet Technologies (CPT) to build a pilot CO2 capture unit at Holcim’s Höver cement works, near Hannover, based on Hereon’s PolyActive membrane technology. The objective of the unit is to demonstrate the performance, economics and operability of the capture technology at scale. Following this the partners will seek to establish a framework for the technology’s implementation in Holcim’s other cement plants in Germany.
Initial tests are scheduled to commence in the first quarter of 2022 with the first phase of the project, capturing 5600t/yr of CO2, scheduled for start-up in the second quarter of 2023. If successful, it is planned to expand the unit in two further phases capturing 170,000t/yr and 1.3Mt/yr starting-up in 2024 and 2026 respectively. The final phase will capture over 90% of the carbon dioxide emissions from the Höver plant and deliver the CO2 in high-purity liquid form for use or sequestration.
CPT is working with Hereon, part of the Helmholtz Association of Research Centres, Germany’s largest research organisation, to commercialise their PolyActive membrane technology after a decade of development. This technology is designed to capture CO2 from carbon rich gas streams and has already been technically proven in the laboratory and piloted in two coal-fired power stations.
Vicat aims to start cultivating spirulina at Montalieu-Vercieu cement plant in summer of 2022
20 October 2021France: Vicat says it aims to start cultivating spirulina at its Montalieu-Vercieu cement plant in the summer of 2022 as part of its Cimentalgue project. It plans to grow 1t/yr until 2024 as part of a trial looking at volume and quality, according to the Agence France Presse. It will use CO2 and waste heat from the plant to grow the cyanobacteria that can be used as a food source.
The project is being conducted with Algosource and the GEPEA (Process Engineering for Environment and Food) laboratory at the University of Nantes. TotalEnergies is also involved as a financial backer. The project has a budget of Euro2m and is also supported by the Environment and Energy Management Agency (ADEME).
Sweden: Cementa has announced that its Stockholm cement terminal will no longer receive deliveries of its Slite brand cement and will instead begin solely stocking the company’s fly ash cement from 1 December 2021. The producer says that the transition will reduce the carbon footprint of the terminal’s products by 30,000t/yr. Slite cement will continue to be available from the nearby Köping and Oxelösund cement terminals.
Russia: Krasnoyarsk Cement has installed a continuous monitoring system for emission control at its Krasnoyarsk cement plant. It carried out the upgrade under the government’s national Ecology project. The system will transmit daily average emissions data to the Krasnoyarsk Territory Ministry of Ecology and Nature Management. Members of the public will be able to access the submissions on the ministry’s website.
Managing Director Dmitry Kireev said “According to the current legislation, the installation was supposed to start working before 31 December 2028. However, due to the fact that the enterprise is located within the city, we voluntarily assumed increased obligations and launched online monitoring of emissions ahead of schedule."
Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO2. EuropaPress has reported that the use of CO2 would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO2 from the concrete’s production.
