Promising carbon capture from Calix, HeidelbergCement



Calix has conducted a study at a HeidelbergCement subsidiary’s Belgian facility on low emissions intensity lime and cement with strongly endorsed results.

The final output report of the LEILAC-1 project, titled Roadmap 2050, detailed the cost reduction capabilities of a full-scale low emissions intensity lime and cement (LEILAC) plant.

The techno-economic study found that the plant could capture carbon for around €14 to €24 ($AUD22 to $37) per tonne of carbon dioxide avoided – compared to the current market average of €39 to €80 per tonne ($61 to $126).

The report was commissioned by the LEILAC consortium, made up of key industry companies HeidelbergCement, CEMEX, Tarmac, Lhoist and Solvay, plus engineering and research entities TNO, Imperial College, PSE, Quantis, and Carbon Trust.

The consortium is now working on the LEILAC-2 project which is the in FEED (front end engineering design) stage and will assess alternative fuel sources for the full-scale cement plant.

This second phase will take place at HeidelbergCement’s Hannover facility in Germany.

In April, Calix signed a non-binding agreement with Adbri to develop a Calix calciner for lime production with carbon dioxide capture capabilities.

Calix chief executive officer and managing director Phil Hodgson said these technologies were becoming the norm throughout the industry.

“We have seen a significant increase in inbound inquiries in Calix technology driven by the rapidly increasing interest in environment, social responsibility and governance, from countries, companies and investors,” Hodgson said in April.

This aligns with a key learning from the Roadmap 2050 report which stated that “the cement and lime industries are dedicated to decarbonising”.
