Project features
- Scalable and modular design will be retrofitted into a Heidelberg Materials (formerly HeidelbergCement) plant with a low-impact integration into the host plant’s operations.
- The project will demonstrate the use of alternative and renewable fuel sources.
- The project will validate: the anticipated capital and operational expenditure for full scale application; a modular design for scale-up; operability and maintenance details; and integration and plant layout considerations.
- In addition to demonstration of the main technology targets, the project includes analysis of the potential destination of the captured CO₂. While there are no current plans to actually store or use the CO₂ from Leilac-2, this analysis will enable a better understanding of the potential uses or safe geological storage options.
Milestone #1
Leilac-2 passes Financial Investment Decision (FID) 23 March 2022.
- Leilac-2 passed its Financial Investment Decision (FID) to build a demonstration plant with a target capture capacity of 100,000 tonnes of CO₂ per year at very low cost. It will be integrated into an operational Heidelberg Materials’ cement plant. Supported by the EU’s Horizon 2020 scheme, the design aims to use fuels, processes, and efficiencies as close as possible to the host plant. The resulting design aims to demonstrate the lowest cost and most energy-flexible solution for capturing CO₂ emissions from any lime or cement plant, of any size, anywhere in the world.
- This FID milestone has been achieved despite the complications arising from the global pandemic and the Russian invasion of Ukraine. We are now proceeding with detailed design, purchasing long-lead items, and expecting to commence construction in 2023.
Milestone #2
Publication of the Front End Engineering Design (FEED) Study Summary 13 October 2023.
“Leilac-2: A new and improved design and revised timeline”
The Public FEED Study for Leilac-2 provides insights into the engineering of the demonstration plant that will be built at an operational Heidelberg Materials’ cement plant. The design aims to use fuels, processes, and efficiencies as close as possible to the host plant.
The resulting design supports the project partner’s vision for low-cost decarbonisation, and a design that can be scaled to address all a cement plant’s process CO₂ emissions. The key features of Leilac-2’s design now include:
- Targeted capture capacity of 100,000 tonnes per year of >95% purity CO₂;
- Four calciner tubes in one furnace chamber;
- A preheater string for heat transfer from flue gas;
- Fuel flexibility, with staged operations for natural gas, through to biomass and ambition for full alternative fuel (AF) use;
- Full heat integration with the plant, with safe material conveying;
- Use of typical cement plant equipment allowing for easy integration, operation, and maintenance.
In particular, the development of a replicable multi-tube module within one furnace chamber provides the basis from which Leilac can scale towards its full-scale vision.
