This Small Business Innovation Research Project develops new technologies to culture microalgae as a source of biomass for use in the production of biodiesel fuel. There is a critical worldwide need for new, renewable sources of energy to reduce our dependence on the dwindling supplies of fossil fuels. Biodiesel produced from plant biomass offers very high potential. Microalgae are the most efficient plants that can produce oil for biodiesel, with potential annual yields of 5,000-10,000 gallons of oil per acre, 100 times higher than soybean or rapeseed oil crops. However, large-scale and cost-effective methods to culture and harvest microalgae (and extract the oils they contain) are lacking. This project involves research using the Controlled Eutrophication Process (CEP), an innovative, multi-stage microalgae cultivation system that produces dense populations of single-celled algae in high-rate algal ponds circulated by large, efficient paddlewheels. The CEP concept will be adapted to develop cost-effective microalgae-biodiesel production processes that can utilize both agricultural wastewater and underutilized saline water as supply water for high-rate algal production ponds. Additional benefits derived from the CEP biodiesel production process include wastewater treatment with freshwater recovery, nutrient recycling, greenhouse gas abatement and co-production of biofertilizers, feed supplements, and electricity. Sales of these valuable byproducts will help to offset the biodiesel cost and improve the competitiveness of this environmentally-friendly bioenergy resource. The overall impact of the development of efficient techniques for using microalgae to produce biofuels will be of immense value in assisting the U.S. economy in a successful transition to renewable energy and have an immense positive environmental impact on the world as a whole.

这个小企业创新研究项目开发新技术，培养微藻作为生物质的来源，用于生产生物柴油燃料。全世界迫切需要新的可再生能源，以减少我们对日益减少的化石燃料供应的依赖。 由植物生物质生产的生物燃料具有很高的潜力。 微藻是生产生物柴油的最有效植物，每英亩潜在年产量为5，000 - 10，000加仑油，比大豆或油菜籽油作物高100倍。 然而，缺乏培养和收获微藻（并提取它们所含的油）的大规模和具有成本效益的方法。该项目涉及使用受控富营养化过程（CEP）的研究，CEP是一种创新的多阶段微藻培养系统，可在大型高效叶轮循环的高速率藻类池塘中产生密集的单细胞藻类。CEP概念将被调整，以开发具有成本效益的微藻生物柴油生产工艺，可以利用农业废水和未充分利用的盐水作为高速率藻类生产池塘的供水。CEP生物柴油生产工艺带来的其他好处包括废水处理、淡水回收、养分回收、温室气体减排以及生物肥料、饲料补充剂和电力的联合生产。 销售这些有价值的副产品将有助于抵消生物柴油的成本，并提高这种环保生物能源的竞争力。 开发利用微藻生产生物燃料的有效技术的总体影响将在帮助美国经济成功过渡到可再生能源方面具有巨大价值，并对整个世界产生巨大的积极环境影响。
