Leilac Newsletter December 2023

Welcome to Issue Number 46 of the Calix Newsletter.

In this special edition, we take the opportunity to introduce the new Leilac newsletter. Leilac’s newsletter will provide regular updates on its progress to develop and deploy decarbonisation solutions for the cement and lime industries, in addition to other applications of its technology, such as Direct Air Capture of atmospheric carbon dioxide.  

Leilac is of course the first example of our capital light, licensing strategy in action. Carbon Direct Capital Management’s investment of €15 million for a 7% stake in Leilac Limited demonstrated how impact investment at the subsidiary business level could provide look-through value for specific applications of the Calix technology and accelerate its development and commercialisation. 

The subsequent spin-off of Leilac enabled investment in a single-focused team and the development of application specific technology beyond Calix’s core platform. It has been satisfying to see the progress the Leilac team has made to date and the momentum that is building within the company. 

Most recently, Leilac announced the signing of a global and perpetual licence agreement with Direct Air Capture company, Heirloom. Direct Air Capture is a method of removing carbon dioxide directly from the atmosphere, something the International Panel on Climate Change predicts will be needed at the scale of 1–10 billion tonnes of CO2 per year if we are to limit global temperature rises to 1.5 °C. 

Leilac’s partnership with Heirloom will employ electric versions of Leilac’s same core technology for CO2 capture from limestone. It opens up a rapidly emerging new market for Leilac with significant public and private sector support, particularly in the US. It will also support and accelerate the electrification and scale-up of Calix’s core platform technology for other mineral processing applications, including cement, iron and steel, and critical minerals. 

You can read more about our partnership with Heirloom plus a report on a techno-economic analysis of Leilac’s vision for cement decarbonisation at full commercial scale, updates on the Leilac-2 and Leilac-1 projects, and an opportunity to get to know some of the Leilac team in the first edition of the Leilac newsletter that follows. 

In other Calix news, the 2024 financial year is off to a good start with all KPIs currently on track across the group. Following a successful Financial Investment Decision, work continues with our joint venture partners Pilbara Minerals on the construction of a demonstration plant to produce a mid-stream sustainable lithium salt product. Construction is expected to commence in April-June 2024, with the production of the first lithium salts targeted for Apr-Jun 2025.  

Our expanded iron ore testing program continues following significant interest in our Zero Emissions Steel TechnologY (ZESTY). Early pilot-scale testing showed excellent metallisation across a range of ore types, including hematite ores from the Pilbara. A Front-end Engineering and Design study for a 30,000 tonne per annum zero CO2 emissions ZESTY iron plant is expected to be completed by the end of the calendar year.  

We also recently published our Sustainability Report for 2023, which details our ambitions for sustainability across our own operations and the progress we are making. The full report is available on the Calix website.  

I hope you enjoy this first edition of the Leilac newsletter, and you can subscribe here to ensure you stay up to date with future editions. Our regular programming will resume in the new year with the next Calix newsletter. In the meantime, I wish you all an excellent end to the year.
