The production of biofuels from microalgae requires efficient photobioreactors in order to meet the tight constraints of energy efficiency and economic profitability. Current cultivation systems are designed for high-value products rather than for mass production of cheap energy carriers. Future bioreactors will imply innovative solutions in terms of energy efficiency, light and gas transfer or attainable biomass concentration to lower the energy demand and cut down production costs. A new generation of highly developed reactor designs demonstrates the enormous potential of photobioreactors. However, a net energy production with microalgae remains challenging. Therefore, it is essential to review all aspects and production steps for optimization potential. This includes a custom process design according to production organism, desired product and production site. Moreover, the potential of microalgae to synthesize valuable products additionally to the energetic use can be integrated into a production concept as well as waste streams for carbon supply or temperature control.
从微藻生产生物燃料需要高效的光生物反应器，以满足能源效率和经济盈利能力的严格限制。目前的培养系统是为高价值产品设计的，而不是为大规模生产廉价能源载体设计的。未来的生物反应器将在能源效率、光和气体传递或可达到的生物质浓度方面提出创新的解决方案，以降低能源需求和降低生产成本。新一代高度发达的反应器设计展示了光生物反应器的巨大潜力。然而，利用微藻生产净能源仍然具有挑战性。因此，必须审查所有方面和生产步骤，以挖掘优化潜力。这包括根据生产生物、所需产品和生产场地进行定制的工艺设计。此外，微藻除了用于能源之外，还有合成有价值产品的潜力，可以将其整合到生产概念中，以及作为碳供应或温度控制的废物流。
