The new federal ordinance for emission control ((44a BImSchV) which came into force in Germany during June 2019, provides for the continuous monitoring of nitrogen oxides emissions (NOx) and for monitoring the catalytic converter through temperature measurements. This ordinance also affects biogas plants and could lead to additional costs for operators. This is why August Storm GmbH has developed the “STORM NOx-Logger” solution, able to facilitate data collection and readings and to make these available to customers.
