Visit at Deponigas ApS

On the 1st of September 2019 Jörgen Held visited Deponigas ApS in Denmark within the framework of the LFG Baltic project. Deponigas ApS has developed a dual-fuel concept which allows utilisation of low calorific landfill gas with methane content down to ~10% as fuel for power production.

Deponigas ApS operates 8 facilities around Denmark. Diesel engines from Volvo Penta, John Deere and Cummins have been modified to operate in dual fuel mode. Diesel is used to ignite the lean pre-mixed landfill gas/air mixture which gives a simple and robust operation. The engines are able to operate over a wide range of loads but Deponigas ApS has developed strategies to operate them at a high load to keep the diesel consumption low in relation to the landfill gas consumption.
