"Researchers in the Aquatic Species Program at the Solar Energy Research Institute are developing species of microalgae that have high percentages of lipids, or oils. These lipids can be extracted and converted to diesel fuel substitutes. Because microalgae need carbon dioxide (C0₂) as a nutrient, optimal microalgae growth occurs in CO₂-saturated solutions. For this reason, the authors of this study sought to identify possible large-scale sources of CO₂ for microalgae-based liquid fuels production. The authors concluded that several such promising sources exist."@en . "CO₂ sources for microalgae-based liquid fuel production"@en . . . . . . . . . . . . "Solar Energy Research Institute." . .
