Associated causal chains
This component is part ofInstallation causal chains— from cause to effect (gas quality → engine → exhaust gas → heat → efficiency). The AI reads the entire chain, not just the individual value.
Link with the entire installation
A CHP unit is never alone: electricity, heat and gas are linked, and with PV and battery storage, it becomes a system. The AI calculates the entire installation.
Frequently asked questions
What is the main difference between natural gas CHP and biogas CHP?
The main difference lies in the gas quality: natural gas is highly purified, while biogas (CH4 52–55 %) requires pretreatment to remove H2S and moisture.
Why is desulfurization so important for biogas CHP units?
Hydrogen sulfide (H2S) causes massive corrosion of metal components and destroys the lubricating capacity of the engine oil, which is why desulfurization is mandatory.
Which CHP unit offers more stability in continuous operation?
Natural gas CHP units operate technically very stably due to the higher methane content and constant gas quality. Biogas CHP units are also stable but require precise monitoring of the gas composition.
From when is a biogas CHP unit economically viable?
A biogas CHP unit is relevant if the availability of biomass and corresponding subsidies (e.g., EEG) justify the investment in desulfurization.
How does methane content influence CHP performance?
A higher methane content leads to a higher calorific value per unit of volume, which directly and positively influences the specific power and efficiency of the CHP unit.
Are natural gas and biogas CHP units technically equivalent?
Yes, both types of installations use similar combustion technologies; they only differ by the required pretreatment of the fuel and the respective promotion incentives.
