CCS on Cement - Lehigh Study

Lehigh Cement (Lehigh) and the International CCS Knowledge Centre (Knowledge Centre) on November 28, 2019 announced a joint feasibility study of a commercial-scale carbon capture and storage (CCS) project. The study targets the feasibility to capture the majority of the carbon dioxide (CO2) from the flue gas of Lehigh’s Edmonton, Alberta cement plant; which is estimated at a capture rate of 600,000 tonnes of CO2 annually.

With total emissions from the global cement industry contributing between 7% and 8% of global CO2 emissions CCS offers a proven technology to reduce greenhouse gas emissions (GHG) in this hard to abate sector. Post combustion flue gas is remarkably similar in cement or coal thermal plants and CCS lessons learned can be readily adapted and transferred across the industries.

The Leigh CCS Feasibility Study will encompass engineering designs, cost estimation (at an AACE Class 4) and a fulsome business case analysis. It will target a 90-95% CO2 capture rate, with the foundational learnings from the Boundary Dam 3 CCS Facility (BD3) and the Knowledge Centre's work to reduce cost and risk through the advancement of second-generation CCS.

 

Objectives of Lehigh CCS Feasibility Study

Phase I - Pre-feasibility Study

  • The pre-feasibility study was conducted by the Knowledge Centre in collaboration with Lehigh.
  • The objectives of this phase include: to source capture proponents through an evaluative request for proposals process; define out-of-scope activities to be conducted by appropriate engineering support teams, scaled-estimates of costs, schedule and budget for phase II.
  • Status: complete

Phase II - Feasibility Study

  • The feasibility study is being conducted in collaboration of Lehigh and the Knowledge Centre.
  • The objectives of the feasibility study include: to deliver a cost estimate of Class 4 feasibility study; to secure one or more capture vendors to provide engineering design tailored to the Lehigh plant; to manage the process and engage third parties, as necessary; to complete a detailed business case; and to develop the budget for Front End Engineering Study (FEED).
  • Status: underway

Phase III – FEED and Execution

  • Following the completion of the feasibility study, a FEED Study would provide detailed engineering design and integration to Class 3 estimate and finalize the business case for final investment decision.                              

 

 

 

Partner Information

Emissions Reduction Alberta (ERA) is investing $1.4M in the feasibility study.  ERA invests the proceeds from the carbon price paid by emitters to develop and demonstrate innovative technology that reduces GHG emissions and strengthens the competitiveness of new and existing industries in Alberta.

HeidelbergCement - Lehigh's parent company - is one of the world’s largest building materials companies.  At the heart of its core environmental policies is climate change protection. The company has committed to a 30% reduction in its CO2 emissions by 2030 compared to 1990 levels. The deployment of CCS is the only viable approach available to the company to meet its 2030 GHG reduction target
