Calix And Heidelberg Materials Join Forces For Leilac-2 Project

Calix And Heidelberg Materials Join Forces For Leilac-2 Project - Carbon Herald

Calix Limited, an environmental technology company based in Australia, has revealed that its subsidiary, Leilac Limited, has joined forces with Heidelberg Materials to establish a Joint Venture for the construction of the Leilac-2 demonstration plant at Heidelberg Materials’ Ennigerloh cement plant in Germany.

By combining their expertise and resources, Calix and Heidelberg Materials aim to further develop and commercialize Calix’s breakthrough carbon capture technology, known as Leilac, which has the potential to significantly reduce CO2 emissions in the cement manufacturing process.

After the successful pilot-scale Leilac-1 project at Heidelberg Materials’ cement plant in Lixhe, Belgium in 2019, the construction of the Leilac-2 project is now underway.

The goal of the Leilac-2 project is to showcase a scalable unit that can effectively capture around 100,000 tonnes of unavoidable process CO2 emissions generated in cement and lime manufacturing each year. 

Detailed engineering work for the location-specific integration has been ongoing since the project’s relocation to Ennigerloh earlier this year. Once construction and commissioning are completed, Leilac-2 will be in operation for up to three years to test and showcase the technology’s performance and functionality. 

The final costs of the project will depend on the completion of this work, although it is anticipated that there will be no significant changes to the project’s scope or goals. So far, the project has received €16 million in funding from the European Union’s Horizon 2020 program and is backed by financial and in-kind support from the project’s consortium partners.

The timeline for the Leilac-2 initiative hinges on obtaining permits, with construction set for 2025 and commissioning planned for 2026.

In the meantime, Heidelberg Materials and Leilac are also working together to explore the early stages necessary for building a large-scale commercial version of the Leilac technology at one of Heidelberg Materials’ cement plants, in conjunction with the construction of Leilac-2.

Assuming the success of Leilac-2, Leilac-3 would be the final step in scaling up the technology, increasing the capture capacity by up to five times compared to the demonstration plant.
