Photobioreactor - Research and Breakthroughs

  • The Green Solar Collector (GSC), a photobioreactor designed for area efficient outdoor cultivation of Microalgae uses Fresnel lenses and light guides to focus, transport and distribute direct light into the algae suspension. Calculating the path of rays of light, so-called ray tracing, is used to determine local light intensities inside the Photobioreactor based on the focused rays of sunlight  (Jan-Willem F. Zijffers, Sina Salim 2008)
  • Valcent's HDVB (High Density Vertical Bioreactor) algae-to-biofuel technology mass produces algae vegetable oil which is suitable for refining into a cost-effective, non-polluting biodiesel.Valcent's HDVB Bioreactor system can be deployed on Non-arable land requires very little water due to its closed circuit process. Principles of fluid mechanics, gas–liquid mass transfer, and irradiance controlled algal growth are integrated into a method for designing Tubular Photobioreactors in which the culture is circulated by an airlift pump. A 0.2 m3 photobioreactor designed using the proposed approach was proved in continuous outdoor culture of the microalga Phaeodactylum tricornutum. (E. Molina, J. Ferna´ndez, 2000).
  • Light transfer in bubble sparged photobioreactors for H2 production and CO2 mitigation (Halil Berberoglu, 2007)
  • Edmund. T and LeeMichael J. Bazin designed a Helical air-lift reactor of 0•315 l capacity, which provides an improved way to cultivate photosynthetic organisms when compared to a 0•625 l stirred reactor. The improvement results from an approximately three-fold increase in the surface area: volume ratio of the reactor.
  • A novel type of closed tubular photobioreactor was set up at the Academic and University Centre in Nove Hrady, Czech Republic. This photobioreactor was based on solar concentrators (linear Fresnel lenses) mounted in a climate-controlled greenhouse on top of the laboratory complex combining features of indoor and outdoor cultivation units. The dual-purpose system was designed for Algal Biomass production in temperate climate zone under well-controlled cultivation conditions and with surplus Solar Energy being used for heating service water. The cultivation system proved to be fully functional with sufficient mixing and cooling, efficient oxygen stripping and light tracking.
  • Solix claims that they have a unique photobioreactor design that will cut costs of growing in algae by 90%. They have a method by which the CO2 circulation is done in a far more efficient manner by which they can reduce the operating costs of the energy required for bubbling the CO2. They are using some sort of flat plate photobioreactors instead of  usual tubular photobioreactors and  the shape of the bioreactor increases the amount of sunlight absorbed by the plates.
