Values are estimated from selected feedstock assumptions.

Assumptions

Formula assumptions

Solid Digestate (kg/day)
Quantity of feedstock (kg) x TS% - Raw Biogas (kg/day)
Liquid Digestate (L/day)
Quantity of feedstock (kg/day) - Solid Digestate (kg/day) - Raw Biogas (kg/day) + Quantity of feedstock (kg/day)
Raw Biogas (scm/day)
Quantity of feedstock (kg/day) x TCVs% x 50%
Refined Biogas (scm/day)
Raw Biogas (scm/day) x Methane Content%
Raw Biogas (kg/day)
Raw Biogas (scm/day) x 1.03
Bio CNG (kg/day)
Refined Biogas (scm/day) x 0.72

Biogas FOM Calculator FAQ

What is the biogas FOM calculator used for?
It models biogas output planning based on feedstock inputs and your selected solids and methane-related parameters.
Which parameters are used in the FOM calculator?
Feedstock selection, quantity, TCVs, and methane content are used to compute the expected output values.
How can FOM outputs help with project planning?
They help you compare expected raw biogas and refined biogas outputs for better budgeting and decision-making.
How do I generate the FOM calculator report?
Enter your values and click “Generate Report” to create the FOM calculator report.
