Black & Veatch Corporation is partnering with Global Thermostat (GT), Sargent & Lundy, ExxonMobil Research and Engineering, Southern Company Services, and Elysian Ventures LLC to execute an initial engineering design of a commercial-scale carbon capture, utilization, and storage direct air capture (CCUS-DAC) system that captures at least 100,000 net tonnes/year of carbon dioxide (CO2) from the atmosphere. The lead system, designated as DAC+, consists of a DAC unit utilizing GT’s sorbent contactor technology coupled with a natural gas-fired combined heat and power (CHP) plant, the DAC+ designation indicating modification of the DAC system to enable capture of the CHP unit flue gas.
