摘要: The rapid depletion of fossil fuels and “peak oil” are driving the R&D in bioenergy and biofuels worldwide. While bio-based energy and fuels can potentially contribute to environmental, social and economic goals, however limited feedstock supplies and negative/low profitability are currently two significant challenges in commercial development. It is noteworthy in both USA and China that the recent large-scale diversion of food crops to biofuels production has significantly increased food prices in a short period. This has raised questions of environmental impact, sustainability and reduced profitability of biofuels companies due to rising demand and limited supply of feedstock. An innovative non-crop production system for biofuels is to cultivate microalgae to produce oils, carbohydrate-rich biomass and clean biofuel gases. Microalgae are readily cultured microscopic organisms which, like plants, use photosynthesis to convert the sun’s energy into chemical energy while removing CO2 from the atmosphere. Microalgae are much more efficient converters of solar energy and CO2 than any known terrestrial plant. It is reported that microalgae are capable of producing in excess of 30 times the amount of oil (per year per unit area of land), when compared to terrestrial oil seed crops. Moreover, the non-oil fraction of the microalgae can be processed to produce ethanol or other bio-products. Alternatively, microalgae can be cultured to produce hydrogen from sunlight and water using their photosynthesis and hydrogenase system. This microalgae-to-biofuels concept has originated since 1940 and is gaining enormous attentions worldwide very recently. This presentation will critically review the history, state-of-the art, R&D challenges and directions in realizing microalgae as a “reality” biomass feedstock from its “potential” promise. The results from the research program in our laboratory will be discussed as case analysis.
