wood pellets
solid biomassDESNZ 2025 Wood Pellets. Scope-1 CO2e (CH4+N2O) is separate from the biogenic combustion CO2 ('outside of scopes'). Wood chips are a related DESNZ product (NCV 13.6 MJ/kg, density 253 kg/m³) not separately catalogued in v0.1.
- Wood-pellet energy content depends on moisture and feedstock; the figure is representative, not exact.
- Biogenic CO2 from pellet combustion is reported on a SEPARATE line ('outside of scopes'), not silently zeroed.

Assumptions
- density: assumed wood pellets density 650 kg/m³ at bulk, as sold
- heating value basis: energy on LHV/NCV basis, 17.28 MJ/kg
- heating value basis: energy on HHV/GCV basis, 18.694 MJ/kg

HHV/GCV vs LHV/NCV Higher heating value counts the heat of condensing water vapour; lower heating value does not. The gap can be 5–20%.Why fuel conversions are approximate Density, calorific value and emission factors are material properties that vary — so fuel results are sourced estimates, not constants.
