The Environmental Benefits of Biomass

Biomass is often called “carbon neutral” as the amount of CO2 released is equal to the amount of CO2 absorbed up until this point, however, issues like transport and pumping costs mean it isn’t truly carbon neutral, but is extremely efficient when compared with other technologies such as CHP or Coal.

Environmental Benefits of Biomass

To give an indication of just how effective biomass systems can be as a means to reducing emissions, below is a table which compares the CO2 emissions of various fuels:

Fuel Type Kg of COemissions per kWh
Woodchip 0.016
Wood Pellet 0.034
Gas 0.216
Oil 0.298
Coal 0.394

Biomass does create some challenges such as NOX and particulate emissions, but the industry has evolved to create technical solutions which can substantially mitigate this.  Solutions such as Electrostatic Precipitators, for example, can retain the overwhelming majority of fly ash which stops it being released into the atmosphere.

Broadly speaking, larger biomass schemes are capable of reducing CO2 emission by considerably more than smaller schemes, for example, a 1MW biomass project we recently installed for a University will generate over 1,000 tonnes of CO2 reduction, whilst the 6.5MW project at the University of St Andrews is capable of generating 6,000 tonnes of CO2 reduction per annum.
