Adjustment of the LAI resolution for granting a formaldehyde bonus according to EEG 2009 for combustion engines of biogas plants
On 5th/6th September 2017, the German Working Group of the Federal States on Immission Control Issues (LAI) has, on its 134th meeting, decided to change a stipulation on this topic of the year 2008. The goal is to continue the uniform support of technologies to reduce the formaldehyde concentration in exhaust gases of combustion plants generating electricity and operated with biogas by means of the EEG.
According to this, as of 1st July 2018 the increased basic remuneration of 1.0 ct/kWh is only to be granted if a formaldehyde emission value of 20 mg/m3 (referring to 5 % O2) is not exceeded by an existing combustion engine plant operated with biogas. Apart from that, the previous regulations remain unchanged.
As a notified body in Germany according to § 29b of the Federal Pollution Control Act (BImSchG), Müller BBM carries out emission measurements at CHP units on plants for the thermal/energetic utilization of biogas (subject to licensing according to the German Federal Pollution Control Act (BImSchG) in connection with, among others, No. 184.108.40.206 of Appendix 1 of the 4th of the German Federal Immission Control Ordinance (BImSchV)). In this process, gaseous emissions, usually nitrogen oxides (NOx), carbon monoxide (CO), sulphur dioxide (SO2) and formaldehyde, are measured. The measurements serve as verification of compliance with the emission limits, also with regard to the EEG funding.
