“Least Costly” CCUS Solution Declared Ready to Deploy for Power Generation and Industrial Sectors


Honeywell International Inc. said it will work with the University of Texas at Austin (UT) to commercialize lower-cost carbon capture technology for the power generation and industrial sectors.

The project was developed by researchers from UT’s Texas Carbon Management Program (TxCMP). An advanced amine solvent “allows you to capture carbon dioxide (CO2) more cheaply and with greater efficiency using smaller equipment,” according to Honeywell. The technology offers “viable project economics today under current CO2 policies in North America and Europe.”

“As the world proactively seeks technological solutions that limit greenhouse gas emissions, we recognize that carbon capture technology is an important decarbonization lever available today to reduce emissions in industries at carbon-intensive that have few alternative options, such as steel mills and fossil fuel-fired power plants,” said Ben Owens of Honeywell, vice president and general manager of the company’s sustainable technology solutions. working with UT Austin, our advanced solvent carbon capture system will enable the lowest cost of CO2 captured after combustion.”

UT’s Gary Rochelle, who leads TxCMP, said, “Our decades of research have led to carbon capture technology that can significantly reduce carbon emissions. The licensing agreement with Honeywell allows us to commercially extend this in ways that make a major contribution to zero emissions efforts to combat global warming and reduce pollutants in surrounding communities.

The system takes CO2 from the flue gases, and it is absorbed in an amine solvent and then sent to a separator where the emissions are separated from the solvent. The CO2 is then compressed for geological sequestration or used for other purposes.

According to Honeywell, the technology “can unlock project economics for ‘hard-to-reduce’ industries like steel, cement, chemical plants, and coal, natural gas and bioenergy plants.” It can also be installed in existing plants or included in a new installation.

For a typical 685 MW coal-fired power plant, the application of the amine scrubbing system would capture 3.4 million tonnes/year of CO2, which is equivalent to removing nearly 735,000 vehicles from the road each year, according to Honeywell. “With thousands of power and industrial plants around the world, the opportunities for significant emission reductions are enormous,” the company said.

Carbon capture, utilization and storage (CCUS) projects around the world currently capture 40 million metric tons/year (mmty) of CO2, Honeywell said, citing data from the International Energy Agency (OUCH). “In order to align with the IEA’s Sustainable Development Scenario, which shows a pathway to limit the global temperature increase to less than 1.65 Decree C, the capacity of the CCUS project must be multiplied by more than 20 to enable the capture of 840 mmty of CO2 by 2030,” company added.

Honeywell, for its part, has installed 33 million tons of CO2 capture capacity worldwide.

The Honeywell-UT partnership comes amid a slew of CCUS project announcements by oil and gas companies including ExxonMobil, Occidental Petroleum Corp. and Talos Energy Inc. Many large-scale blue hydrogen projects, which involve separating hydrogen from natural gas and capturing the resulting CO2 emissions are also planned in the United States.

The Biden administration, meanwhile, indicated this month that fossil fuel generation associated with CCUS could help the federal government achieve 100% carbon pollution-free electricity consumption by 2030.
