  • Publication number: 20100159578
    Abstract: A Robotic Algae Harvester (RAH) of the present invention works by providing a CO2 collection mechanism that is installed in power plants or vehicles. These systems are available using current technology and have been proven to be scalable. CO2 is then transported to RAH using ships. The RAH will feed and re-circulate algae broth through the photobioreactors (PBRs). The PBRs float in the ocean while the algae through photosynthesis will transform the CO2 into biomass in a continuous process. The extracted algae will processed into a stable mix of oil and bi-product and transferred to the ship that brought the CO2. The algae is then processed onshore in some of the following manners: converted to biodiesel via transesterification; converted to bio-ethanol via fermentation; burned for electricity generation; and/or used as protein for animal feed or food products.

  • Publication number: 20100144017
    Abstract: The present invention is a system for harvesting algae in continuous fermentation. There is a harvester including a main moving belt, a plurality of rollers, and a motor for driving the main moving belt. There is a reactor tank and a vacuum extractor for applying a vacuum over a width of the main moving belt to extract biomass and to dry the main moving belt. The main moving belt has one end in the reactor tanks and another end extended into the vacuum extractor. The algae contained in the reactor tank is collected for further processing, including oil extraction. With algae harvested in the large-scale manner of the present invention, a more efficient oil extraction method can be used because the concentration, temperature, and pressure can be more easily controlled.

  • Patent number: 7732174
    Abstract: A method of using sequential chemostat culture vessels to provide continuous H2 production, in which photosynthetic O2 evolution and H2 photoproduction are separated physically into two separate bioreactors, comprising: a) growing a microorganism culture able to continuously generate H2 by photosynthetically producing cells at about the early-to-late log state in a first photobioreactor operating as a sulfur chemostat under aerobic and/or conditions; b) continuously feeding cells from the first photobioreactor to a second photobioreactor operating under anaerobic conditions and sulfur deprivation conditions resulting from constant uptake of sulfate in the first bioreactor and a low rate of culture flow between the first and second bioreactors, for induction of hydrogenase and H2 photoproduction to allow for continuous cultivation of the microorganism's cells in the first photobioreactor and constant H2 production in the second photobioreactor, and c) H2 gas from the second photobioreactor.

    Abstract: A trough lining assembly is placed in a series of troughs at a biomass processing facility. The trough lining assembly includes a waterproof liner that lies against the sides of a trough, an aerator, and a retention mechanism that retains the aerator at the bottom of the trough. The aerator provides continuous aeration of biomass present in the trough by releasing aerating gas into the biomass along the length of the trough. The continuous aeration also churns the biomass, exposing more of it to the aerating gas and to sunlight. The trough lining assembly improves the efficiency of algae production by stimulating photosynthesis and consumption of carbon dioxide. The trough lining assembly has low production, transportation, installation, and maintenance costs.

  • Publication number: 20090203116
    Abstract: This invention provides a method of delivering light internally to a Photo-Bioreactor growing algae for production of Biodiesel fuel. The invention also provides an improved method of delivering liquid nutrients [I.e. sewage] and carbon dioxide to the growing algae in a Photo-Bioreactor. These results are achieved by a single system which delivers fiber optic light as well as liquid nutrients and carbon dioxide via jets. The net result attained by using this invention is a significant increase in the production of valuable algae with a very small increase in energy consumption. The increase in energy usage is the electrical energy required to power a 150 watt metal-halide bulb.

  • Publication number: 20090197322
    Abstract: A method of growing algae is described that is part of a cogenerational energy production plant in which solar energy from a solar collecting and concentrating field is used to provide photonic energy for the growth and stress phase of algae as well as to provide heat for driving a turbine. The supplementary energy for the power plant is provided by natural gas and by biomethane that is produced by fermentation of the algal biomass. The carbon dioxide that is a by-product of the combustion of both the natural gas and the biomethane is recycled to provide the carbon source for the algal growth.

  • Patent number: 7566551
    Abstract: The present invention provides a method for producing a xanthophyll from a photosynthetic microalga, which includes inoculating a photosynthetic microalga containing a xanthophyll, preferably an encysted microalga, into a nutrient medium to grow the microalga; and encysting the grown microalga, by a single-step culture method in which the growth step and the encystment step are performed continuously using a nutrient medium having a low nitrogen source concentration, or by a two-step culture method in which the microalga is grown in a nutrient medium having a high nitrogen source concentration and then transferred to an encystment medium.

  • Publication number: 20090148927
    Abstract: A method of mass production of algae is provided, including an algae growth trough having an algae introduction end having a first width and an algae extraction end having a second width wider than the first width. Water is supplied to the trough from a water treatment facility and carbon dioxide is introduced to the water from a combustion source. The algae is allowed to grow within the algae growth trough while light is provided to the trough. The algae is extracted from the extraction end of the trough, and as the algae continues to grow under optimal conditions, the algae is continuously harvested for commercial use. The mass production of algae allows for the consumption of enormous amounts of carbon dioxide which can be generated from a coal electrical generation facility or other industrial facility.

  • Publication number: 20090130706
    Abstract: Certain embodiments and aspects of the present invention relate to a photobioreactor including photobioreactor units through which a liquid medium stream and a gas stream flow. The photobioreactor units are floated on a body of water such as a pond or a lake. The liquid medium comprises at least one species of phototrophic organism therein. Certain methods of using the photobioreactor system as part of fuel generation system and/or a gas-treatment process or system at least partially remove certain undesirable pollutants from a gas stream. In certain embodiments, the photobioreactor units are formed of flexible, deformable material and are configured to provide a substantially constant thickness of liquid medium. In certain embodiments, a barrier between the photobioreactor unit and the body of water upon which the unit is floated facilitates thermal communication between the liquid medium and the body of water.
