Abstract: A method of autotrophic cultivation of algae includes cultivating algae in the presence of cultivation media and at least one growth nutrient to produce an algal biomass; and harvesting the algal biomass by separating the algal biomass from the cultivation media and the at least one growth nutrient.

Abstract: Embodiments of the disclosure provide systems and methods for supplying an algae cultivation fluid with nutrients (e.g., carbon dioxide and nitrogen) directly from the atmosphere. Supplying nutrients directly from the atmosphere reduces operational costs and environmental impacts, as well as provides greater flexibility in locating algae farms.

Abstract: An algae cultivation system includes generating a translating hydraulic jump wave that travels across a gas-liquid interface of an algae cultivation fluid contained in the algae cultivation system. The translating hydraulic jump wave has Froude number greater than 1.

Abstract: An open raceway algae cultivation system includes a channel configured to contain an algae cultivation fluid. The channel includes a contraction zone having a width and a depth and an expansion zone having a width and a depth. A pump is configured to circulate the algae cultivation fluid in the channel and includes an entrance and an exit. A width of the contraction zone decreases leading into the entrance of the pump, and a depth of the contraction zone is greater than a depth of at least a portion of the channel located outside of the contraction zone. A bottom of the channel at a beginning of the contraction zone is lower than a bottom of the channel at an outlet of the expansion zone, and the contraction zone increases in depth along at least a portion of its length.

Abstract: Algae cultivation systems and methods account for weather variations that can affect algae cultivation. In one system, an open raceway algae cultivation system includes a channel having a high section and a low liquid collection section. The channel is sloped to allow substantially all of an algae cultivation fluid in the high section to flow downwardly into the low liquid collection section. A barrier is removably positioned in the high section and a drain is positioned in the high section such that, when substantially all of the algae cultivation fluid has collected in the low liquid collection section, any rainwater that falls in the high section flows into the drain, without the rainwater mixing with the algae cultivation fluid in the low liquid collection section.

Abstract: A system and method for creating a useful carbon-enriched media in a reactor which will assimilate carbon into an algae biomass, requires measuring a respective carbon concentration of the media, C(measured), as it enters, and as it leaves the reactor. Operationally, desired carbon concentration values are preset, C(set), and are provided along with values obtained for C(measured) as input to a system controller. Respective differentials between C(measured) and C(set) at the reactor's input and output ports are determined by the controller and are used to control a volumetric fluid flow rate of the media through the reactor. Specifically, the controller establishes a volumetric fluid flow rate of the media as it is passed through an absorber where the media is carbon-enriched by interaction with combustion gases from an external source (e.g. a power plant).
