Description
The cement industry alone is responsible for around 7% of the global greenhouse gas emissions, of which 60% are process emissions released during clinker production. To decarbonize these unavoidable emissions, CO2 Capture and Storage (CCS) is necessary. The EU-funded LEILAC projects aim to demonstrate a new capture technology, with implementation at HeidelbergMaterial’s Lixhe (BE) and Ennigerloh (DE) plants.
Together with the German geological survey BGR, we developed a business case for an integrated CO2 capture, transport and storage value chain in Germany. Several scenarios were evaluated with multiple on- and offshore CO2 transport options, storage locations and upscaling, and considering ongoing and planned transport and geological storage initiatives.
The PSS simulation tool for CCS implementation forecasting and a dedicated techno-economic model were applied for general and sensitivity analysis, considering capture, conditioning, buffer storage, transport, transshipment and storage. At demonstration-scale (0.1 Mt/y), onshore train and offshore ship transport is preferred. When upscaling (1-5 Mt/y), pipeline transport gradually becomes the most economic and practical option. While demo-scale capture remains uneconomic at current energy and emission prices, a full-scale chain is at the economic threshold. Our study highlights the important economies of scale that can be won, which can be supported by government policies that encourage infrastructure upscaling for hubs, joint transport and storage. Early storage opportunities are available in the Danish and Norwegian North Sea. In time, CO2 use and domestic storage can be considered.
