What is Carbon Capture and Sequestration (CCS)?

Carbon capture and sequestration, the process of capturing CO2 from emitters before it enters the atmosphere and storing it deep underground, is the most impactful way to mitigate climate change while ensuring reliable energy supply. Successful carbon capture and storage projects are critical to our clean energy transition.

Carbon Sequestration and Storage with Enchant – Different from Other CCUS Projects

In the past, carbon capture projects utilized pre-combustion coal-gasification processes. Enchant will operate post-combustion, amine-based carbon capture systems, like those already running successfully on a smaller scale. By scaling proven technology, Enchant will enable existing power plants to approach near-zero CO2 emissions.

Optimizing CO2 Storage and Bringing Proven Carbon Capture Technology to All Kinds of Emitters


Enchant utilizes proven amine carbon capture technology for all types of emitters. Although amine has been used to capture pollutants in the natural gas, petrochemical, and refining industries, Enchant’s deployment of amine technology enables the recovery of CO2 from low-pressure streams.


Enchant is developing CO2 storage capacity. With CCS, large amounts of CO2 are kept out of our atmosphere, and the need for underground storage continues to grow. Expanding safe storage capacity is the focus of our R&D.

45Q Tax Credits and Investing in Carbon Capture with Enchant

The 45Q tax credit is an increasingly critical carbon capture incentive. Combined with the declining cost of carbon capture technology—made possible by extraordinary collaborations—45Q tax credits are creating attractive investment opportunities and driving the expansion of CCS.

“The 45Q tax credit enhancements from the Inflation Reduction Act of 2022 will enable Enchant Energy to economically deploy carbon capture technology to mitigate climate change while providing attractive after tax returns to investors.” – Cindy Crane, Enchant Energy, CEO

Advancing the Technology and Business Case for Carbon Capture

In November 2022, Enchant Energy announced that the San Juan Generating Station Carbon Capture Front-End Engineering Design (FEED) Study is now publicly available. The study was partially funded through an agreement with the United States Department of Energy.

The FEED Study was successful in establishing and defining the technical requirements, scope, schedule, and costing for the project to add carbon capture technology to the San Juan Generating Station.

The FEED Study shows that the technical and business cases for adding carbon capture technology to existing coal fired power plants is strong. Enchant Energy will utilize the advances made in carbon capture plant optimization to develop other projects across the company.

The core technology for the carbon capture system uses a proprietary amine‐based solvent carbon dioxide capture system developed by Mitsubishi Heavy Industries America, Inc., (MHIA). An earlier iteration of the technology was successfully implemented in 2016 by MHIA on a slipstream from a coal-fired boiler at the Petra Nova Plant in Texas.

The San Juan Project FEED study is being used to accelerate the development of other projects.
