Germany: The Ministry for Economic Affairs and Climate Action has approved funding for Holcim Deutschland's Höver cement plant carbon capture project. The test phase of the project is scheduled to commence in early 2024. Holcim Deutschland, together with project partners Cool Planet Technologies and Helmholtz-Zentrum Hereon, carried out preliminary testing in 2022. They reported 'positive' results in May 2022.

Plant manager Stephan Hinrichs said "The funding commitment from the federal government is great news for Holcim and our partners. We are doing real pioneering work for the entire cement industry, and look forward to the next step on our way to becoming a climate-neutral company."

Germany: Cool Planet Technologies and Hereon have signed a memorandum of understanding with Holcim Deutschland to deliver a carbon capture system for a carbon capture and storage (CCS) trial at the producer’s Höver cement plant in Lower Saxony. Cool Planet Technologies will install their system, which is based on Hereon’s PolyActive membrane technology. The system will have a capture capacity of 5600t/yr and operate from early 2022 to early-mid-2023. If successful, two subsequent expansions will increase the system’s capacity to 170,000t/yr, commencing operation in 2024, and 1.3Mt/yr, commencing in 2026.

The suppliers say that their membrane-based capture system is capable of reducing the energy intensity and eliminating the need for other chemical inputs in CCS.

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.
