Large-scale carbon capture pilot supported by NETL breaks ground in Illinois

NETL representatives recently attended a groundbreaking ceremony at the City Water, Light and Power (CWLP) facility in Springfield, Illinois to mark the progress of a large-scale carbon dioxide (CO2) acquisition project made possible by funding and project management support from the laboratory. The project is managed by the University of Illinois, in partnership with The Linde Group, BASF Corporation, Affiliated Engineers, Inc., Affiliated Construction Services, Inc. and Visage Energy.

Ron Munson of NETL, technology manager for the lab’s point source carbon capture program, and Krista Hill, federal project manager of the point source carbon capture team, joined other US Department of Energy (DOE) officials in State and city government officials, union officials, University of Illinois executives, CWLP staff and project team members from Linde, BASF, ACS, Visage Energy and the University of Illinois Urbana-Champaign Prairie Research Institute (UIUC).

The large-scale pilot will evaluate a 10-megawatt electrical (MWe) capture system based on Linde-BASF’s advanced amine-based post-combustion capture technology, designed to capture 200 tons of CO2 per day. The project represents an important step toward achieving the Biden administration’s goal of a zero-carbon economy by 2050. The capture system will be installed on the Dallman 4 unit at CWLP, a nominal 200 MWe pulverized coal-fired unit that has been commissioned in 2009 and is one of the cleanest coal-fired power plants in the country, according to the CWLP website.

“The UIUC team has already completed Phase I and II of this project and these achievements have paved the way for the construction and operation of the facility,” said Hill. “The Linde-BASF technology combines BASF’s proprietary solvent with Linde’s process and design innovations to enable significant increases in energy efficiency and lower carbon costs2 recovery from power plants.”

In particular, the BASF solvent allows for a reduction in regeneration energy and a lower solvent circulation rate, while Linde has achieved significant improvements in process design by featuring an advanced stripper interstage heater design to optimize heat recovery in the process.

“Based on the results of small pilot studies, the techno-economic analysis shows that the Linde-BASF technology can bring about a significant reduction in capital costs compared to the NETL base case for a supercritical pulverized coal power plant with CO2 capture,” Hill said.

BASF is the manufacturer and owner of the solvent technology. As a major global player in the chemical industry, BASF is able to reliably produce and supply the solvent in sufficient quantities needed for commercialization, enabling large-scale deployment by eliminating manufacturing-related issues of solvents for large commercial plants can be avoided.

Linde is a world-leading industrial gases and engineering company with unparalleled experience and world-class expertise in the engineering, procurement and construction (EPC) of industrial gas process plants, including CO2 plants and plant operation.

“The Linde-BASF partnership brings together the necessary skills and experience to potentially provide the entire value chain of carbon capture technology, from solvent production to full-scale carbon capture plant ECP, commercial deployment and long-term, continuous operation,” said Hill.

NETL is a US Department of Energy national laboratory that drives innovation and delivers technology solutions for a green and prosperous energy future. Leveraging its world-class talent and research facilities, NETL ensures affordable, abundant, and reliable energy that fuels a resilient economy and national security, while developing technologies to manage carbon throughout the lifecycle, enabling environmental sustainability for all Americans .
