Abstract
A vehicle CO2 capture and utilization system includes a concrete mixer vehicle and a vehicle exhaust capture system. The concrete mixer vehicle comprises a vehicle exhaust and a mixer tank. The vehicle exhaust capture system is located onboard the concrete mixer vehicle. Additionally, the vehicle exhaust capture system includes one or more fluid pathways that fluidly couple the vehicle exhaust and the mixer tank.
Claims20
A vehicle CO2 capture and utilization system comprising a concrete mixer vehicle and a vehicle exhaust capture system;
- wherein:
- the concrete mixer vehicle comprises a vehicle exhaust and a mixer tank;
- the vehicle exhaust capture system is located onboard the concrete mixer vehicle;
- and
- the vehicle exhaust capture system comprises one or more fluid pathways that fluidly couple the vehicle exhaust and the mixer tank.
A vehicle CO2 capture and utilization system comprising a concrete mixer vehicle and a vehicle exhaust capture system;
- wherein:
- the concrete mixer vehicle comprises a combustion engine, a vehicle exhaust, and a mixer tank;
- the vehicle exhaust capture system comprises one or more fluid pathways that fluidly couple the vehicle exhaust and the mixer tank;
- the vehicle exhaust capture system comprises a CO2 capture unit that is located onboard the concrete mixer vehicle and is fluidly coupled to the vehicle exhaust and the mixer tank using the one or more fluid pathways;
- the vehicle exhaust capture system comprises a CO2 storage tank that is fluidly coupled to the vehicle exhaust using the one or more fluid pathways and is located onboard the concrete mixer vehicle;
- the one or more fluid pathways comprise a first fluid pathway extending from the vehicle exhaust to the CO2 capture unit, a second fluid pathway extending from the CO2 capture unit to the mixer tank, and a third fluid pathway extending from the CO2 capture unit to the CO2 storage tank;
- a first flow generation unit is fluidly coupled to the second fluid pathway and is structurally configured to generate fluid flow from the CO2 capture unit to the mixer tank;
- and
- a second flow generation unit is fluidly coupled to the third fluid pathway and is structurally configured to generate fluid flow from the CO2 capture unit to the CO2 storage tank.
A method of carbonizing a cementitious material mixture, the method comprising
- generating CO2 emission using a concrete mixer vehicle, the concrete mixer vehicle comprising a vehicle exhaust and a mixer tank, wherein the mixer tank houses an uncured cementitious material mixture;
- and
- introducing at least a portion of the CO2 emission generated by the concrete mixer vehicle and output by the vehicle exhaust into the mixer tank via one or more fluid pathways fluidly coupled to the vehicle exhaust and the mixer tank, such that CO2 mixes with the uncured cementitious material mixture thereby carbonizing the uncured cementitious material mixture and forming CaCO3 in the mixer tank.
