NEW BIOMASS BIOCOAL COULD OFFER CARBON NEUTRAL SOLID FUEL OPTION FOR THE FUTURE
April 1st, 2013
A SLOW revolution in the use of biomass for firing or co-firing power generation is picking up pace this year as a number of competing technologies for the production of 'biocoal' move more convincingly towards full commercialisation.Biocoal produced through torrefaction - in which dry biomass such as wood, paper, food waste and even sewerage waste is slow-heated anoxically (to avoid combustion) at 200C to 300C to reduce moisture and drive off low-energy volatile chemicals - offers slightly degraded fuel with lower emissions and carbon footprints (it is carbon ...
