Abstract: A method of operating a bioreactor includes containing an algae slurry within the bioreactor for cultivation, discharging a portion of the algae slurry to a heat pump that circulates a refrigerant, and receiving the portion of the algae slurry at a first heat exchanger and transferring heat from the algae slurry to the refrigerant. The method further includes discharging a cooled algae slurry and a heated refrigerant from the first heat exchanger, receiving and compressing the heated refrigerant at a compressor and thereby discharging a compressed refrigerant, and receiving the compressed refrigerant at a second heat exchanger and transferring heat from the compressed refrigerant to a fluid. The method further includes discharging a cooled refrigerant and steam from the second heat exchanger, receiving and expanding the cooled refrigerant at an expansion valve, and receiving and utilizing the steam at a downstream application in fluid communication with the second heat exchanger.

Abstract: A system includes a photobioreactor that provides a channel configured to contain an algae slurry, a duct positioned adjacent the channel and configured to convey a gas, and a barrier separating the duct from the channel and providing one or more apertures to allow a portion of the gas to be injected into the algae slurry from the duct.
