UNLABELLED
Worldwide, microalgal biofuel production is being investigated. It is strongly debated which type of production technology is the most adequate. Microalgal biomass production costs were calculated for 3 different micro algal production systems operating at commercial scale today: open ponds, horizontal tubular photobioreactors and flat panel photobioreactors. For the 3 systems, resulting biomass production costs including dewatering, were 4.95, 4.15 and 5.96 € per kg, respectively. The important cost factors are irradiation conditions, mixing, photosynthetic efficiency of systems, medium- and carbon dioxide costs. Optimizing production with respect to these factors, a price of € 0.68 per kg resulted. At this cost level microalgae become a promising feedstock for biodiesel and bulk chemicals.
SUMMARY
Photobioreactors may become attractive for microalgal biofuel production.

全球范围内，人们正在研究微藻生物燃料的生产。哪种生产技术最合适，这一点存在激烈的争论。对今天在商业规模下运行的 3 种不同微藻生产系统的微藻生物质生产成本进行了计算：开放式池塘、水平管式光生物反应器和平板式光生物反应器。对于这 3 种系统，包括脱水在内的生物量生产成本分别为 4.95、4.15 和 5.96 欧元/公斤。重要的成本因素是辐照条件、混合、系统的光合效率、介质和二氧化碳成本。对这些因素进行优化生产，得出的价格为每公斤 0.68 欧元。在这个成本水平上，微藻成为生物柴油和大宗化学品有前景的原料。
总结
光生物反应器可能成为微藻生物燃料生产的有吸引力的选择。
