Clean biogas with infrasound in one step – step 2

The project ran between April 2019 and December 2019.

The project aimed to investigate whether infrasound technology can be used to make gasification of biomass more efficient to reduce biogas production costs. After the completion of stage 1, the project team assesses that the technology has great potential and thus that there is reason to continue the project to further develop the technology. An important goal was to achieve a continuous process which has been achieved as well as a steady state which has created the conditions for analyzing the gas content.
