Switzerland: LafargeHolcim has announced its participation in a project aimed at increasing the height of wind turbine towers by producing larger bases on-site using 3D concrete printing technology. LafargeHolcim will supply concrete for use with Denmark-based COBOD’s 3D printing technology, while US-based GE Renewable Energy backs the project. The method enables bases to exceed the 4.5m maximum diameter necessitated by road transportation. This increases the maximum height of turbine towers by 100% to 200m from 100m, which in turn raises power generation by 33% to 20.2GWh/yr from 15.1GWh/yr.

LafargeHolcim research and development head Edelio Bermejo said, “Concrete 3D printing is a very promising technology for us, as its incredible design flexibility expands the realm of construction possibilities. Being both a user and promoter of clean energy, we are delighted to be putting our material and design expertise to work in this ground-breaking project, enabling cost efficient construction of tall wind turbine towers and accelerating access to renewable energy”

US: CalPortland has announced the launch of Advancement, a product line of cements containing sustainable materials and produced using renewable processes. These include the replacement of 15% of the Ordinary Portland Cement (OPC) clinker with blended limestone. The company currently offers Advancement Light for aesthetic design and Advancement High Sulphate for general use concrete applications and when high sulphate resistance is required, both of which have 10% lower embodied carbon than OPC. More products are planned to follow.

CalPortland president and chief executive officer (CEO) Allen Hamblen said, “Advancement is a line of products that can be combined with other concrete carbon reduction technologies to further enhance performance and increasingly reduce the embodied carbon of concrete.”

Norway: Norcem, a subsidiary of HeidelbergCement, has signed an agreement with Aker Solutions to order a CO₂ capture, liquification and intermediate storage plant at its integrated Brevik cement plant. The final decision for the project depends on funding from the Norwegian government, which is expected to approve the unit in its national budget for 2021.

The project will use Aker Solutions’ Advanced Carbon Capture (ACC) technology and its S26 amine solvent. Once complete the unit will capture 0.4Mt/yr of CO₂. This will be transported to the Northern Lights project for permanent storage offshore beneath the North Sea.

Philippines: LafargeHolcim subsidiary Holcim Philippines has said that digital innovations enabled it to continue serving its customer base throughout the coronavirus lockdown. The company said that utilisation of its customer service platform grew to 91% year-on-year in May 2020 from 56% in May 2019.

Through its information sharing platform E-Konekta, the company has hosted 40 events covering fields from Holcim Philippines’ corporate vision and health and safety to business networking. Holcim Philippines sales senior vice president William Sumalinog said, “Particularly in times of crisis, a customer’s interaction with a company can trigger an immediate and lingering effect on his or her sense of trust and loyalty. It is vital for us to keep our warm ties with customers so they continue to feel being part of the Holcim family.”
