The Center for Energy Technology (ZET) of the University of Bayreuth combines the complementary competencies and activities in energy related research of currently nine chairs of the Faculty of Engineering Sciences. Aspects of thermal, electrical, chemical, but also biological generation, transmission, storage and utilization of energy are researched at the ZET, albeit originally distributed over the individual chairs. In 2018, it became possible to relocate and combine these activities on campus, in the new building of the Technology Alliance of Upper Franconia (TAO).Within ZET, the Chair for Bioprocess Engineering (LBPT, Prof. Dr. Ruth Freitag) in particular focusses on biological aspects of regenerative energy technology. Research centers on microbiological and engineering aspects of technical facilities in the area of environmental engineering, such as biological waste digestion plants (biogas production), composting plants, or waste water treatment plants. Important research questions currently concern process variants allowing for flexibilization of the microbial conversion, as well as aspects of scale up / scale down of the plants. Effects of certain impurities such as microplastic, metal(oid)s, or nitrogen compounds, but also problems of technology transfer constitute additional research priorities.Technical facilities in waste management usually require reactor volumes of several 1000 m3. Concomitantly, these plants have to continuously ensure important municipal services (waste disposal, wastewater treatment). Therefore, their availability for scientific experiments is limited. The question of how to provide data with predictive value for the technical plants in laboratory or pilot plant scale experiments has been discussed at length in our group. Currently research at the LBPT is limited to reactor with a size below 100 L. The bridge to the technical facilities is made via so-called satellite experiments. However, these are inherently limited and cannot provide the necessary information. Instead an anaerobic pilot plant, which is much closer in size to the technical plants (low m3-range) is required, as only such a reactor would be large enough to establish the full biological diversity of a technical plant.The reason for this current limitation in research is historical. When the chair was founded in 2003, there was no hall space available for the set-up of a large pilot plant. This has now changed with the new TAO building, where sufficient space is available to accommodate the requested anaerobic pilot plant, which would close a substantial gap in our scientific capabilities. The requested pilot plant is designed for research purposes. In particular, it can be flexibly operated and linked to a number of peripheral modules. As a result, modules from other groups of the ZET or from TAO can be integrated and evaluated, e.g. from the fields of energy storage, heat utilization, or power-to-gas.

拜罗伊特大学能源技术中心（ZET）结合了工程科学学院目前九个主席在能源相关研究方面的互补能力和活动。热，电，化学，以及生物发电，传输，存储和能源利用方面的研究在ZET，虽然最初分布在各个椅子上。2018年，这些活动可以在校园内的上弗兰肯技术联盟（TAO）的新大楼中重新安置和联合收割机。在ZET内，生物过程工程主席（LBPT，Prof. Dr. Ruth Freitag）特别关注可再生能源技术的生物学方面。研究中心在环境工程领域的技术设施的微生物和工程方面，如生物废物消化厂（沼气生产），堆肥厂或废水处理厂。目前重要的研究问题涉及允许微生物转化灵活化的工艺变体，以及工厂规模扩大/缩小的方面。某些杂质的影响，如微塑料，金属（oid）s，或氮化合物，以及技术转让的问题构成额外的研究优先事项。废物管理的技术设施通常需要反应器的体积为几千立方米。与此同时，这些工厂必须不断确保重要的市政服务（废物处理，废水处理）。因此，它们用于科学实验的可能性有限。如何在实验室或中试规模的实验中为技术工厂提供具有预测价值的数据的问题已经在我们小组中进行了详细的讨论。目前LBPT的研究仅限于100 L以下的反应器。连接技术设施的桥梁是通过所谓的卫星实验建立的。然而，这些都是固有的限制，不能提供必要的信息。相反，需要一个厌氧中试工厂，它在规模上更接近技术工厂（低m3范围），因为只有这样的反应器才足以建立技术工厂的全部生物多样性。2003年成立时，没有大厅空间可用于建立大型试验工厂。现在，随着新的TAO大楼的建成，这种情况已经发生了变化，那里有足够的空间来容纳所要求的厌氧试验工厂，这将缩小我们科学能力的巨大差距。所要求的试验工厂是为研究目的而设计的。特别是，它可以灵活地操作并连接到许多外围模块。因此，可以集成和评估来自ZET或TAO的其他组的模块，例如来自能量存储、热利用或电力到天然气领域的模块。
