The algal fuel industry has existed since the 1980s without fully commercializing a product. Algal fuels are potentially viable replacements for fossil fuels due to their fast cultivation, high oil content, carbon dioxide sequestration during growth, and ability to be grown on non-arable land. For this thesis, six companies from 61 investigated were interviewed about their history with biofuels, technological changes they have gone through, and views for the future of the industry. All companies interviewed have moved away from fuel production largely due to high production costs and have moved primarily toward pharmaceuticals and animal feed production as well as wastewater treatment. While most do not plan to return to the biofuel industry in the near future, a return would likely require additional legislation, increased technological innovation, and coproduction of multiple products.
