in partnership with the USDOE to study ION Clean Energy’s CCS technology. This 18-month pilot, scheduled to run until the end of 2024, will inform the implementation of CCS at Sutter Energy Center and provide a model for reducing carbon emissions at existing power plants by at least ninety-five percent.


In addition to the large scale pilots mentioned above, OCED also supports CCS FEED studies, including the following, announced in May 2023:

pipeline FEED study; developing a CO2 storage field development plan; establishing underground injection control Class VI well permitting; and ascertaining National Environmental Policy Act compliance through the development of an Environmental Information Volume.


Navajo Transitional Energy Company, LLC (NTEC): Four Corners power plant integrated carbon capture and storage, Navajo Nation The proposed project includes an integrated CO2


capture retrofit of post-combustion CO2 capture technology, transport, and storage for


the coal fired Four Corners power plant located on the Navajo Nation. The proposed project has an estimated capability of capturing a minimum 2


emissions from the power


plant, representing 10 million+ tons of CO2 per year. The project uses Mitsubishi Heavy


Industries’ KS-21™ solvent for carbon capture and NTEC has partnered with Enchant Energy, LLC as the CO2


site development.


University of Illinois at Urbana-Champaign: Integrated capture, transport, and geological storage of CO2


emissions from City Water,


Light and Power’s Dallman 4 coal fired plant, Springfield, Illinois


The proposed project includes an end-to-end carbon dioxide capture, transport, and storage solution for Dallman 4, a pulverised coal power


capture project developer, and


other institutes for development of the CO2 offtake concept, including pipeline and storage


plant in Springfield, Illinois. The project is estimated to capture 2 million tons of CO2


The project team will complete a cost estimate for all elements of the project: the carbon capture system, balance of plant, and integration of the system into the existing facility. The FEED study will also include all process, controls, civil, structural, electrical, environmental, constructability, risk analysis, and permitting aspects to evaluate technical and economic viability of the project.

Duke Energy Indiana: CCS project at Duke Energy’s 618 MWe coal fuelled Edwardsport IGCC power plant


OCED is working with Duke Energy to demonstrate the company’s CCS technology design. The study seeks to evaluate the feasibility of capturing and storing carbon dioxide from the flue gases of the two heat recovery steam generators at the Edwardsport integrated gasification combined cycle power plant in Knox  evaluate the use of the Honeywell Advanced Solvent Carbon Capture process, which has a technology readiness level of 7.

The project envisages development of a “robust Community Benefits Plan”, along with both preliminary and final design engineering packages, cost estimates, an environmental health & safety assessment report, and a final FEED report. Taft Carbon Capture (a business unit of Oxy Low Carbon Ventures): Cypress Carbon Capture Project, located at Taft cogen facility, Hahnville, Louisiana, a natural gas fired, 3x1 combined cycle CHP plant, in an industrial area on the Mississippi, 30 miles west of New Orleans OCED is working with Taft Carbon Capture, LLC to design a FEED study to evaluate the cost and performance of a commercial-scale, post- combustion carbon capture system. The carbon capture system being evaluated would separate and prepare up to 2.6 million metric tons of carbon dioxide per year for  efficiency. This evaluation includes the development of a commercial-scale design package that encompasses application of carbon capture data duplicative from smaller-scale demonstrations by the technology provider. Integration engineering will be provided by a major engineering, procurement, and contruction firm experienced in FEED studies for similar systems.

OCED is working with Tampa Electric to complete a FEED study to design and determine the cost of retrofitting ION Clean Energy’s post-combustion carbon capture technology with pipeline transport and secure geologic storage to the Polk power plant. This technology is expected to capture  emissions, which is nearly 3 million metric tons of CO2


per year.


As part of the project, the CCS system will be designed to maintain the necessary flexibility of a dispatch-based generating asset, which “pushes the boundaries of scalability, maximises energy efficiency, and utilises a transformational solvent, while maintaining a robust and flexible system.”


The project will include project management, community benefits work, a CO2

Entergy Services: Integrated CO2 capture facility at the Lake Charles natural gas fuelled combined cycle power plant, Westlake, Louisiana


OCED is working with Entergy Services to complete a FEED study to develop a full-scale integrated carbon capture project for Entergy Louisiana’s Lake Charles power plant. The plan is to investigate the cost of retrofitting post-combustion carbon capture technology using Mitsubishi Heavy Industries’ KS-21™ solvent.


Entergy has partnered with Talos Energy to develop an offtake agreement. As part of this arrangement, Talos will investigate the development of a sequestration site approximately 40 miles from the Lake Charles Power Station and a pipeline to transport the captured carbon to the sequestration site for secure storage.


The project will include project management, community benefit work, carbon capture FEED study, CO2


transportation FEED study,


storage field development plan, initiation of the National Environmental Policy Act process, and the necessary permits for carbon storage.
