What is natural gas vs. biogas CHP unit??

Biogas CHP units (CH4 52–55 %) require H2S desulphurisation and robust engine oils; natural gas CHP units run more stably with a higher methane content — biogas enables EEG subsidies, natural gas KWKG surcharge, both are technically equivalent.

What the AI reads from these values

What the AI reads
  • Methane content (CH4) as an indicator for the calorific efficiency
  • H2S concentration to determine the corrosion risk in the engine
  • Moisture content to assess the wear rate on cylinder components
  • Gas flow rate (m3/h) as a basis for power query and load adjustment
Scenario

Monitored: continuous

The scenario: if the methane content drops slowly, the engine begins to knock without an alarm occurring, leading to power reduction and wear. The AI: detects the quality trend early and reports it before the knocking causes damage. It identifies the trend before the limit value is reached.

Why this matters

The correct selection of fuel minimises unplanned downtime due to corrosion damage or engine wear. Biogas CHP units enable the use of EEG subsidies for renewable energies. Natural gas CHP units benefit from the KWKG surcharge and offer a stable base load with high gas purity. Gas volume (m³/h) · methane content (%) → — kWh/h calculation path: gas volume × methane content × 9.97 kWh/m³ (calorific value of methane)
