Carbon Capture, Utilization and Sequestration (CCU/S) solutions -- technologies that collect the CO2 produced from industrial processes -- will play an increasingly important role in addressing climate change.
LafargeHolcim is working on a number of CCU/S pilot projects so that it can replicate the best solutions across its 270 sites. Working with other multinationals as well as start-ups, the pilots are evaluated in terms of cost, technical feasibility, compatibility with CO2 usage opportunities, and other aspects of viability and scalability.
Our objective is to develop a handful of solutions for use and storage that can be combined in different ways and environments. However, no single solution will be perfectly scalable as different environments present different conditions, from local partners to geological conditions that are favorable for storage.
LafargeHolcim is currently spearheading over twenty CCU/S projects in the US, Canada and Europe, placing the company at the forefront of low-carbon construction.
Key initiatives include:
- Westküste100 where CO2 from the LafargeHolcim Lägerdorf plant in Germany will be transformed into a synthetic fuel, that can be used at nearby airports. This nine-company consortium, based in Germany, is focused on the creation of low-carbon solutions and the development of end-to-end sustainable business practices across industries to avoid waste in all sectors.
The CO2MENT project in Canada is testing an innovative end-of-pipe solution for CO2 removal and reuse from a cement plant with partners Total and Svante. Total and Svante are also partners -- together with Oxy Low Carbon Ventures, LLC
(a wholly-owned subsidiary of Occidental) -- on a joint study of a commercial-scale carbon-capture facility at the Holcim Portland Cement Plant in Florence, Colorado (US) to permanently sequester CO2 underground.
- Other potential solutions look to capture CO2 for subsequent use as chemicals, mineralization and biomass production.
The Plants of Tomorrow -- a key enabler for Carbon Capture, Utilization and Sequestration solutions
A key enabler to Carbon Capture Utilization and Sequestration solutions, the “Plants of Tomorrow” initiative will upgrade the Group’s production fleet and reconfigure the infrastructure of its sites and contribute to furthering the circular economy through the use of industry 4.0 innovations such as Artificial Intelligence, machine learning and recycling of materials.
By future-proofing 270 industrial global sites and making them carbon-efficient, The Plants of Tomorrow will create digital, circular and interconnected sites and will rely in large part on the implementation of traditional levers such as energy efficiency, biomass fuel and clinker factor.
Addressing climate change will also require the adoption of state-of-the art, innovative approaches that include digital solutions to maximize clinker reactivity and predict cement strength.
Smart online digital control solution: Near-infrared spectroscopy, a digital online control technology, can be used to analyze alternative fuel properties during feeding and compensate for quality variations in real-time using the most economical fuel mix. This solution increases the use of alternative fuels, minimizes energy costs and contributes to more stable kiln operation and improved product quality. It also contributes to the circular economy pillar of The Plants of Tomorrow initiative and to reducing CO2 emissions.
CemQ: Predictive quality models use machine learning algorithms to correlate the quality of each production batch with the relevant production parameters while minimizing clinker factor. This enables accurate forecasting of cement quality in real-time at any point during the production process. It also reduces overspending up to 15 %, which helps us meet quality targets and achieve CO2 reductions and energy savings.
To further advance these efforts, as part of The Plants of Tomorrow initiative, LafargeHolcim is fostering partnerships with start-ups to find novel ways to address CO2 emissions.
