This project focuses on the design, integration and optimization of a flexible natural gas combined cycle plant with carbon capture, capable of operating in a highly variable renewable energy environment. Renewable energy sources such as wind and solar power offer unique solutions in our quest to reduce global carbon dioxide (CO2) emissions. However, the increasing penetration of these high variable renewable energy sources into the existing market creates complications for carbon-based electricity generating systems that form the backbone of the power generation industry. The objective of the project is to integrate a flexible, low temperature CO2 capture system (E-CACHYSTM) into a natural gas combined cycle power plant to attain a net-zero carbon electricity system. Envergex LLC’s technical approach is based on an innovative, but proven multi-phase sorbent technology for post combustion capture of CO2 from flue gas. The hybrid sorbent technology, which consists of a regenerative sorbent and a novel heat exchange system for optimal energy recovery, seamlessly integrates into the natural gas combined cycle architecture. The size of the proposed carbon capture system can be matched to the average capacity factor of the power plant to enable constant operating conditions in the capture system and reduce overall plant operating expenses. This innovative integration reduces capital expenditures by 31% compared to NETL’s state-of-the-art technology system. The technology can enhance the economic and energy security of the United States by incorporating valuable natural gas resources with advanced, flexible carbon capture and sequestration technologies that work in unison with renewable energy technologies.
