Cogeneration with renewables

The costumary used primary fuel for cogeneration is natural gas. Biogases from biological digestion, from landfill sites, from the chemical industry and pyrolysis gas of municipal waste or wood have become an interesting financial and environmental option for operators throughout the world.

40 years of experience in the utilization of such gases in gas engines have made Jenbacher AG the technologically leading company in this field.

One of the most well-known "non-natural gas" applications is the utilization of biogas produced in sewage treatment plants. The dried sludge is subsequently fed into a digestion tank, where the anerobic fermentation process sets free biogas. The biogas itself is composed, on average, of 50% to 60% methane (CH4), 30% to 40% carbon dioxide (CO2) and small amounts of residual gases.
