Three of the six selected projects will also explore DAC operations in three distinct geographical locations, with varying climates, in an effort to create a first-ever DAC system that can capture 100,000 tonnes of CO2 per year. Currently, no existing DAC system has this CO2 capacity.
- Execute early-stage engineering designs for DAC technology – The Black & Veatch Corporation (Overland Park, Kansas) team will develop an initial engineering design of a DAC system to be placed in Odessa, Texas, Bucks, Alabama, and Goose Creek Illinois, aimed at capturing 100,000 tonnes of CO2 from the atmosphere per year. (Award amount: $2,500,000)
- Implement an initial design of three carbon farms using a commercial-scale DAC system - Silicon Kingdom Holdings Limited (Dublin, Ireland) will complete three initial designs using a commercial-scale, passive DAC system that absorbs CO2. This design, developed at Arizona State University (Tempe, AZ), aims to capture a steady capacity of 1,000 tonnes of CO2 per day. (Award amount: $2,500,000)
- Utilize low-carbon energy sources to power commercial scale DAC operations - The University of Illinois (Champaign, Illinois) team will develop preliminary designs for large-scale direct air capture and work with partners to perfect the designs to permanently store CO2 at underground facilities in Wyoming, Louisiana and California. In addition to examining the effects of different climate conditions, the project will measure the impact of using different low-carbon power sources (e.g., geothermal, solar, wind or waste heat)to reduce the life-cycle emissions of DAC technology. (Award amount: $2,499,798)

Therefore, carbon capture and management will be a crucial step in curbing climate change.
There are two main categories of carbon emissions: point-source and nonpoint-source. Point-source emissions come from a single source such as a power plant or a factory. Nonpoint-source emissions are harder to pinpoint and to address because they cover a widespread area and can come from a variety of sources like automobiles, airplanes, boats, and more.
“In order to offer a more robust solution to carbon management, you have to be able to address both point-source emissions and nonpoint-source emissions,” said Kevin OBrien, director of the Illinois Sustainable Technology Center (ISTC).
The U.S. Department of Energy National Energy Technology Laboratory (DOE-NETL) has partnered with ISTC in a nearly $2.5 million project to develop preliminary designs and determine feasibility for the first commercial-scale direct air capture and storage system (DAC+S) for CO2 removal in the United States.
This 18-month project will explore the possibility of pulling 100,000 tonnes of CO2 from the air annually. Project principal investigator OBrien believes this amount will help offset steep upfront costs and make the service profitable, at least at a commercial scale.
“The potential impact this could have would be immense, because now you can address unavoidable nonpoint sources by pulling CO2 out of the air, hopefully in any type of climate anywhere around the world,” said OBrien.
The project will use DAC technology provided by the Swiss company Climeworks. Climeworks has built and operated several DAC plants in various climates across Europe, among them the world’s first industrial-scale DAC plant in Hinwil, Switzerland, and the world’s largest DAC+S plant, Orca, in Hellisheidi, Iceland.
Three different climates, different renewable energies, and different approaches to carbon storage
Widespread deployment of DAC systems in the U.S. must account for wide variations in regional climates. Temperature and relative humidity can impact the efficiency of CO2 removal technologies.
The ISTC-led team will address climate efficiency challenges by testing the large-scale DAC systems and storing the captured CO2 at three test sites across the U.S., examining the effects of different climate conditions on CO2 storage.
- Hot and very dry climate – A test site in southern California near the Salton Sea will be powered by geothermal energy, with the captured CO2 stored in a saline aquifer.
- Hot and humid climate – A test site in Louisiana will use solar energy to power the DAC system while storing the captured CO2 in a saline aquifer.
- Midcontinental climate – A test site in Wyoming will operate using wind power and store the captured CO2 in a depleted natural gas reservoir.
In addition to Climeworks, major partners in the project consortium include Kiewit Power Engineers, Lawrence Livermore National Laboratory, Gulf Coast Sequestration, North Shore Energy, Sunpower, Ormat, and Sentinel Peak.
