We have been receiving numerous inquiries on how to judge the merit of specific algae-to-energy proposals.  Common questions relate to productivity estimates, projected water use, land availability and the care and feeding of the algae. Because we are unable to answer the volume of individual questions we are receiving, we decided to try and demonstrate the types of information that can be developed or inferred for algae-to-biofuels projects.  We used a hypothetical project proposed for Dallas, Texas.  All data inputs were real, although some information and methodologies we used are proprietary and were not disclosed.  We tried to demonstrate the basic types of information that are necessary in order to properly evaluate a proposed project.  Note that we did not address cost estimates in this exercise.  The costs associated with supplemental heat (if needed), water, CO2, nutrients, land acquisition, etc., vary too widely from one geographic area to another to be addressed in any general sense. 

We began by looking at water requirements, a critical issue when designing open bioreactors. Succeeding months we added additional information on other issues related to the hypothetical project, such as the energy required for heating or cooling and CO2 utilization. 

After reviewing this section, we hope you have a better understanding of the types of information that are available and/or how they can be developed.
