Carbon capture, utilisation and storage

To meet global climate targets, cement and lime producers must be able to implement credible and economical technologies that capture unavoidable CO₂ process emissions.

Accessible, low cost CO₂ transport and storage infrastructure is also vital to enable the successful decarbonisation of our industries.

The transition to a carbon neutral world

The Sustainable Development Goals (Global Goals) are a universal call to action to end poverty, protect the planet and ensure that all people enjoy peace and prosperity.

Just like the Global Goals, we recognise the need to balance social, economic and environmental sustainability.

Leilac’s innovation, development and partnerships are aligned with the Global Goals, helping to accelerate our work in delivering the transition to a carbon neutral world.

We’re creating sustainable industries and a sustainable planet.

Cement, lime & climate change

From essential infrastructure like buildings and roads to applications in renewable energy, steel, pharmaceuticals and agriculture, cement and lime provide the foundations of our societies and economies.

They are indispensable to our way of life. And they will be critical in ensuring global living standards continue to improve in the transition to a carbon neutral world.

Environmental Impact

The cement and lime industries are also amongst the largest contributors to climate change, accounting for approximately 8% of global CO₂ emissions.

Since 1990, significant effort has been made to reduce the energy and emissions intensity of cement and lime production, resulting in a 20% decrease in CO₂ output. Despite these efforts, cement and lime remain the largest single source of industrial emissions.

The call to decarbonise

To preserve our planet, cement and lime producers must urgently decarbonise. To preserve our way of life, we must do so at the lowest possible cost.

As penalties for emitters increase across the world, decarbonising is not only a matter of environmental responsibility for producers. It is a matter of survival.

Carbon utilisation

Carbon utilisation consists of a range of technologies that use or convert CO₂ to make valuable fuels, feed, chemicals, building materials or other products. For some existing applications, captured CO₂ can replace conventional CO₂ feedstocks, while new applications can be developed based on incentives to utilise CO₂.

The market for CO₂ utilisation, however, will likely remain small relative to the volume of CO₂ that will need to be captured from industry.

Unavoidable C0₂ Emissions

Unlike other industries, most of the CO₂ produced in the manufacture of cement and lime is unavoidable. Cement is made by heating limestone with clay and other materials. When heated to high temperatures, limestone (CaCO3) is converted into calcium oxide or quicklime (CaO), releasing CO₂ in the process.

In fact, for every 1,000kg of cement, 700kg of carbon dioxide is produced. The unavoidable process CO₂ emissions account for around two thirds of the total emissions from the industry, with the balance resulting from the energy emissions required to heat the reaction. Decarbonising cement and lime requires a solution that addresses both.

Our Solution

Leilac’s technology seeks to deliver highly efficient capture of unavoidable process emissions in cement and lime production.

It is being developed to be clean energy ready to enable the sustainable decarbonisation of cement and lime.

Carbon storage

The primary means of ensuring the CO2 generated by industry does not reach the atmosphere is to permanently store or sequester it. Geological storage reservoirs are the only volumes that can store CO2 at a sufficiently large scale in volume and time.
