To prepare for post-EEG operation of its biogas plant, Bioenergie Hünxe GmbH has commissioned Hitachi Zosen Inova to carry out an extensive modernisation of the digestion system and install a membrane gas upgrading system for biomethane production. This will enable the biogas plant, which has been in operation since 2005, to continue running profitably without EEG feed-in tariffs. The retrofit of the plant, located just under 30 kilometres north of Duisburg, is due to be completed by mid-2025.
