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.

France: Ireland-based Ecocem has opened its new innovation centre, the Centre of Excellence, in Paris. The purpose of the facility is to help to accelerate the development of new technology for the decarbonisation of the cement and construction industries. Ecocem's innovation team will use it for industrial-scale trials in collaboration with industry and academic partners, including Paris-Saclay University and The University of Toulouse. It says that it hopes that one outcome will be the further developmentof the Ecocem reduced-CO₂ product range. Breakthrough Energy Ventures provided funding towards the centre's construction.

Ecocem innovation director Laurent Frouin said “Ecocem is committed to the deep and rapid decarbonisation of the global cement industry. It is essential for the planet and future generations, and it can be achieved through innovation and technology." He added “The cement and construction industries are developing and deploying a range of emission reduction technologies – Ecocem and our new Centre of Excellence will add a further dimension to these efforts.”

France: 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).

Ukraine: NEQSOL Holding Ukraine has filed an application to the Antimonopoly Committee of Ukraine (AMCU) to acquire a stake in Ivano-Frankivskcement. The group will take a loan from ‘leading international’ banks to pay for the stake.

NEQSOL Holding Ukraine manager Volodymyr Lavrenchuk, said “We are hopeful for an approval of the new deal by the AMCU so that we can welcome the high-tech enterprise Ivano-Frankivskсement into the NEQSOL Holding group of companies. We recognise the long-time outstanding results achieved by the Ivano-Frankivskсement management team and staff, who have created one of the most state-of-the-art cement plants in Europe.” He added “Our group of companies has successful experience in financing, including engagement of international financial institutions, which will help to secure the required investments for maintaining a high rate of growth of the cement plant.”
