Collaborative project: Innovative process management for a new generation of flexible biogas plants (BiogasFlex)

Project


Project code: 22408818
Contract period: 01.02.2019 - 31.07.2021
Budget: 576,706 Euro
Purpose of research: Experimental development
Keywords: biogas, renewable ressources

Bioenergy, apart from hydropower, is the only renewable energy source, which is always available without fluctuations. Therefore, the use of biogenic energy sources forms an ideal complement to solar and wind energy for the transformation of the energy system associated with the energy transition. Because the availability of sun and wind depends on natural fluctuations, it is important to ensure sufficient system flexibility. The necessity of infrastructural facilities to be able to react flexibly to changing conditions in supply networks will increase rapidly in the course of further energy system transformations. In this context biogas plants are able to fulfill inherently the so-called timetable suitability, which is essential for the power supply network control. Thus, biogas plants can take over important functions for grid stability and serve the flexibility markets arranged for this purpose in terms of energy. The primary objective is therefore the use of flexible biogas plants for the compensation of disturbances in the distribution grids, resulting from the utilization of fluctuating renewable energies such as wind or solar power. The overall objectives of this joint project are: - Demand-driven biogas production for flexible power production through bioprocessing measures, with which methane production can be increased significantly faster if required than in the current state of the art and research - Concepts for new biogas plants basing on these processes and for the cost-effective repowering of existing plants - new business models for operators of biogas plants This is achieved with a novel process in which hydrolysis/acidogenesis are consistently separated from methanogenesis, allowing start of methane production on demand within a very short period of time.
