Hamilton Locke Advises Calix on Global Licence Agreement with Heidelberg Materials

Hamilton Locke has advised environmental technology company Calix Ltd on a global licence agreement between Leilac, Calix’s cement and lime decarbonisation subsidiary, and Heidelberg Materials, for the use of Leilac’s decarbonisation technology.  

The agreement represents a key milestone in the commercialisation of the Leilac solution, providing a platform for the groundbreaking technology to be rolled out across Heidelberg Materials’ cement plants globally. Calix’s patented technology enables the direct capture of limestone-produced CO2, and has the potential to dramatically reduce CO2 emissions throughout the cement and lime industries.

Reflecting the innovative nature of the technology, the licensing model is described by the company as a “first-of-a-kind for the industry”1, including a variable component linked to the European carbon price/value, and a royalty cap linked to costs versus alternative technologies. The agreement is the next stage in a continuing collaboration between Leilac and Heidelberg Materials, who have been working together since 2014 in the development of the Leilac technology.

Commenting on the transaction, Hamilton Locke Partner, Sarah Gilkes said: “We are delighted to be working with the innovative Calix and Leilac teams on the commercialisation of the Leilac technology. The agreement with Heidelberg Materials represents a significant step on the global journey towards reducing carbon emissions in the cement industry, and we look forward to seeing the impact of this collaboration far into the future.

The team at Hamilton Locke comprised Partner Sarah Gilkes, Special Counsel Ben Cameron and Lawyer Janice Yew, with support from Partner Adam Jeffrey and Special Counsel Kerry Spies.
