What is the energy content of wood chips vs pellets?

Air-dry wood chips (25% moisture): ~13 MJ/kg. Wood pellets (<10% moisture): ~17–19 MJ/kg. Oven-dry wood: ~19–22 MJ/kg. Moisture content has the largest impact on effective energy content.

How does moisture content affect biomass energy?

Every 10% increase in moisture content reduces net calorific value by ~0.8–1.0 MJ/kg. Wet biomass >50% moisture has near-zero net energy value after evaporating water in combustion.

How does biomass compare to natural gas in energy density?

Natural gas: ~55 MJ/kg. Wood pellets: ~18 MJ/kg. Biomass requires 3x more mass for equivalent energy. However, biomass is typically 1/3 the cost per GJ compared to natural gas in many markets.
