Abstract:

As global emission requirements for carbon dioxide (CO₂) continue to become more stringent, existing and new thermal power projects, as well as industrial emitters, may look towards CO₂ capture, utilization, and storage to remain viable and emission compliant.

This white paper highlights best practices and insights that Sargent & Lundy has identified during our engineering support of CO₂ capture projects, with a focus on technology viability, plant integration, economics, CO₂ offtake, project development, and permitting. The goal is to assist owners, financiers, and engineers in the due diligence and planning of CO₂ capture projects. Our findings are based on our engineering support of approximately 60 CO₂ capture projects completed or in progress since 2007, including the Petra Nova CO₂ capture project, which is currently the largest CO₂ capture project in the world.

There are many key considerations when performing due diligence of a CO₂ capture project such as the balance-of-plant capital investment, impact on plant heat rate, proximity to potential CO₂ offtakers, and local permitting restrictions. Sargent & Lundy has addressed these key considerations below through our extensive experience with thermal power plants, air pollution control integration, and previous feasibility, front-end engineering and design studies, and owner’s engineering support for CO₂ capture systems.
