  • Greenhouses are probably the lowest cost photobioreactors, what do you say? I know it does not sound jazzy enough, but greenhouses could provide some of the key benefits that a typical PBR is supposed to provide...

      Greenhouses are excellent facilities to ensure best or optimal environmental parameters to growth microalgae into PBRs. These also aids to increase productivity and to standarize products and production. If starting production costs are high, they can quickly amortized by increasing of productivity.

  • The high capital costs of photobioreactors are due to the costs of construction materials, circulation pumps, nutrient-loading systems and costs for monitoring/instrumentation hardware and software. High operating costs are a result of costs for aeration and mixing, and lighting.

      There are some factors that attempt of photobioreactor efficiency and productivity in order to reduce production costs and increase productivity. Maximize microalgal photosynthetic efficiency; maximize disolved CO2 absorption; minimize hydrodinamic stress; and maximize photobioreactor proportions in relation with area:height sizing.

  • Innovative Aspects of the system:


    * A patent-pending energy efficient LED based photobioreactor for ultrahigh biomass productivity from microalgae.
    * Improved surface enlargement for enhanced mixing and biomass productivity.
    * A pulsed LED lights improve the microalgal flux tolerance for improved biomass productivity.
    * A LED controller for flexible control of the quality of the LED lights from intensity to pulse emission that is not possible using conventional lighting source.
    * The LED lighting can be superviced via Ethernet network using a PC in order to provide operators with full capabilities and scalability.
    * Energy savings of the LED lights is >49% compared to HPS lamps.
    * A patent-pending thermal management of the LED lights ensures highest possible performance and longivity of min. 50.000 hours operation.
    * The LED lights are ECO friendly and contain almost 100% reusable material.
    * The LED lights are environmentally friendly and contain no harmful material, such as mercury.
    * The LED lightd cost less to operate and require very low maintainance in comparison to HPS lamps.

      @Narsi- I myself have always found this as a problem with algae PBR's, "Why in the world would someone spend so much on operating costs to, really, not get that much oil?" Then in the last month or so, as I was applying for an environmental energies grant it sort of struck me. As long as you can look at your entire process or system and you; take in more CO2 than put out, and produce more energy than what you purchase, then you will have an extremely efficient system. If Gaya3 was to perhaps raise this system to one day hold 1 million liters of water with this system -running all LED's on solar panels(producing no variable costs, only purchasing the panels)- then his PBR would produce outrageously more algae than that of an open raceway pond system holding 1 million liters. However, I will give you that the start-up costs would be IMMENSELY high. I looked at LED systems and the cheapest price was $100,000 for lighting one medium sized raceway pond. Add on another $100,000 or so for solar as well as power regulators etc. It becomes a headache when looking at the initial price. Running on a conservative start-up model, I believe PBR's would be impossible. If you do have enough of a start-up fund though, the most environmentally sustainable(not including CO2 emission in the production of Solar panels and LED's) route to take is making a large PBR system. I am trying to combine both of these systems with my little high school science fair project. Come check it out at http://www.facebook.com/AlgaeFuel

  • The cost components of PBR can be categorized as high cost, medium cost and low cost components

    High Cost - Turbidostat, Remote Control Softwares, Lighting components
    Medium Cost - Sensors used for detection of pH, temperature, dissolved oxygen
    Low Cost - Valves, Air-Blow Units, Bubble Humidifiers

    Is the above are the key cost components, what are the various strategies being adopted to tackle each of the components?

      Re: Low-Cost PBR's. I received this from the National Algae Association. Heard they are testing about a dozen different low-cost PBR's. "New Collaborative Industrial Photobioreactor Testing Facility Opening January 2012 Due to the lack of sufficient data on the performance of industrial-scale photobioreactors, fermentation, dewatering/harvesting and extraction equipment, the NAA is announcing a new collaborative testing center starting in The Woodlands, Texas beginning in January, 2012. "If we are really going to help this emerging industry, we must address certain basic businss facts. Investors and commercial lenders must be able to confirm growth rate data, production levels, and/or scalability of turn-key industrial algae production equipment before making investments, financing or loan guarantee committments to any algae production farm. As new industrial photobioreactors begin to come online, the NAA strives to continue to do due diligence confirming growth rates and performance data, and to incorporate the results into the specifications being developed by its Engineering and Oil Specs Committees. Industrial photobioreactors are key to the success of the algae production industry and must prove scalability before expanding onto hundreds of acres. Various new lower cost materials are being tested to help lower CAPEX as well as document life-cycle issues. Process engineers, plastic extruders, sensor, material, tankage, dewatering/harvesting and extraction providers will do collaborative testing and benchmarking. "

  • Researchers from the Michigan State University (MSU) have developed a ePBR. These ePBRS have the capability to mimic the outdoor environment (simulating both sunshine and pond water)and still providing a controlled environment. Phenometrics Inc is the company manufacturing and selling these ePBR's. Full Story - http://greatlakesecho.org/2011/11/22/simulated-outdoor-environments-strengthen-algal-biofuel-research/
