Abstract

Methane losses from biogas plants are problematic, since methane emitted into
the atmosphere contributes to global warming, and any losses may thus reduce the
environmental benefits of biogas production. A tracer gas dispersion method was used to
measure total methane emissions from seven biogas plants, and more measurement
campaigns are planned. Emissions varied between 1.3 and 13.4 (kg CH4 h-1), and losses
expressed in percentages of production varied between 0.3 and 6.4%. The tracer gas
dispersion method was found to be useful in quantifying total methane emissions from
biogas plants, whereas the detection and quantification of individual leaks at the plants
require other methods.
