Biogas Calculator FAQ
What does the biogas calculator calculate?
It estimates raw biogas, refined CBG output, LPG equivalent, electricity output, and projected revenue based on your inputs.
How is CBG estimated in this biogas calculation?
CBG output is derived from the raw biogas produced and the methane content you set in the calculator.
How do I generate the biogas calculator report?
Enter your values and click “Generate Report” to create your calculator report.
What is biogas density (kg/m3) used for?
The calculator uses biogas density assumptions to convert between mass and volume so the outputs match your selected inputs.
What is a common density range for biogas in kg/m3?
A practical planning range is often around 1.10 to 1.20 kg/m3, but your exact value depends on methane content and operating conditions.
