PEAK 2020

Biogas technology has a huge unfulfilled potential both in Denmark and worldwide for replacing our need for fossil-based natural gas. Biological gasification of biomass enables production of green energy, but also recycling of important nutrients to and from the surrounding society. However, operation of biogas plants are often associated with odor emissions, which has been recognized as one of the most significant barriers for further expansion of the Danish biogas sector by both the Danish Environmental Protection (EPA) and Energy Agency (DEA). Currently, biofilters are used for reduction of odor emissions, but the current technology struggles to handle peak loads of sulfur-containing gaseous species such as H2S, which can cause filter breakthrough of malodorous emissions.

Consibio in collaboration with BBK, Aarhus University and Nature Energy initiated the PEAK Project funded by EUDP.

The PEAK project seeks to optimize both cost efficiency and performance of current biofilter technology through the use of new data and IoT based technologies, in order to break down one of the most significant barriers for the further propagation of the biogas industry. Through this project, a test-filter equipped with an IoT-based sensor and control platform will be constructed at the research biogas plant at AU Foulum.

In order for biogas to be a robust and publicly accepted alternative to other sources of green energy and nutrient recycling, odour emission has to be minimized at all times. This requires very stable operation of the biofilters used for odour abatement, which can only be realized if the filters are monitored and controlled closely.
