GE-led carbon capture technology project announced

GE Gas Power will lead a multi-company carbon capture project being funded by the U.S. Department of Energy.

The company’s front-end engineering design (FEED) study “Retrofittable Advanced Combined Cycle Integration for Flexible Decarbonized Generation” will receive US$5,771,670 in federal funding from the DOE’s Office of Fossil Energy and Carbon Management. This funding is focused on carbon capture, utilization, and storage (CCUS) for power generation applications with a goal of commercial deployment by 2030. GE Gas Power will work with energy company Southern Co., Linde, BASF, and Kiewit to develop a detailed plan for integrating carbon capture technologies with a natural gas combined cycle plant to capture approximately 95% of carbon dioxide emissions generated.

The FEED study will be focused on Southern Co. subsidiary Alabama Power’s James M. Barry Electric Generating Plant, located in Bucks, Alabama, USA, which is powered by two GE 7F.04 gas turbines. GE will research advanced technology and control concepts to integrate the combined cycle power plant with Linde’s Gen 2 carbon capture solution based on BASF OASE blue technology. The project will also include gas and steam turbine equipment enhancements to improve the carbon capture process, with a goal of reducing the impact of the carbon capture process on the power plant’s output, performance, and equipment cost, the company said.

GE said this retrofittable solution can be applicable to other power plant sites and serve as a template for lowering carbon emissions across more than 1500 F-Class gas turbines worldwide, which currently deliver up to approximately 280 GW of electricity daily.

“We are committed to leading a more sustainable power industry that will provide the world with the affordable, reliable, and less carbon-intense electricity it needs today, while maintaining laser-focused on researching, developing, and demonstrating the technologies that will be required for the future,” said Scott Strazik, CEO of GE Power. “GE is pleased that the Department of Energy has recognized the importance of this study and grateful for their support. We look forward to joining forces with Southern Company, Linde, BASF and Kiewit to execute this study focused on the integration of carbon capture technologies on a fully functional natural gas combined cycle power plant to help lower the cost of carbon capture and improve the operability and flexibility of the integrated plant.”

Complex integration

Because of the complexity of the integration of CCUS technologies into an existing natural gas power plant, this FEED study—a detailed blueprint and operating business guide—will represent a prerequisite for future construction projects and it can accelerate commercial deployment of other projects, the company said. GE will lead the full-scale integration of the study with the goal of preserving the attributes of a natural gas combined cycle plants, which the company said are critical to enable a renewable energy-based future including dispatchability, lower carbon intensity, high flexibility and reliability, and low capital cost.

“For the success of this study, the collaboration with Southern Co. and Linde, BASF and Kiewit is crucial,” said John Catillaz, director of Decarbonization – Marketing, GE Gas Power. “To develop a sustainable and viable carbon capture solution integrated into the existing power plant, we will go beyond the scope of the study to consider the economics and the performance of the plant holistically, including a plan for the transportation and storage of the captured carbon dioxide emissions.”

“As a leader in energy innovation, Southern Co. is advancing CCUS as part of a portfolio of technologies to achieve a net-zero future, while providing customers with clean, safe, reliable and affordable energy,” said Dr. Mark S. Berry, Southern Company vice president of research and development. “We look forward to working with GE and other members of the FEED study project team to evaluate how this new technology could potentially improve the opportunities for integrating carbon capture with natural gas power plants.”

GE, Linde cooperation

GE and Linde signed an agreement in December 2021 to strengthen their existing cooperation with a specific focus on exploring carbon capture and storage opportunities in North America by leveraging GE’s expertise in power generation technology and plant integration with Linde’s experience with post combustion amine-based carbon capture processes. This agreement will also provide new opportunities for North America customers that operate GE gas turbines to pursue the adoption of CCUS technologies.

“Developing large-scale decarbonization solutions for industrial processes and value chains is at the core of Linde’s mission to make the world more productive,” said Dominic Cianchetti, senior vice president of Linde Engineering Americas. “Therefore, Linde is pleased to collaborate with GE on developing projects for gas power CO2 capture in North America.”

BASF will provide OASE® blue technology. “OASE Blue was developed specifically for large-scale post-combustion capture (PCC) technology,” said Todd Spengeman, Business Director – Standard Amines & OASE Gas Treating Excellence. “With low energy consumption and exceptionally flexible operating range is paramount technology for use in flue gas carbon capture from sources such as fossil power generation plants or steam turbines.”

Kiewit will provide engineering procurement construction capabilities.

“The U.S. Department of Energy’s commitment to and investment in the development of accessible, scalable carbon capture solutions is crucial to the decarbonization of power generation,” said David Claggett, senior vice president at Kiewit Energy Group, Inc. “We look forward to working with the powerhouse of technical experts that are involved in the study and to making a meaningful, positive contribution in reducing carbon emissions at natural gas combined cycle facilities.”
