Torrefied biomass. The perfect CO₂ neutral coal substitute is maturing

Biomass upgrading to a coal-like fuel is long a topic of R and D. Today, the torrefaction technology is mature allowing industrial-scale production and cost competitive large-scale supply of CO₂ neutral fuel. Torrefaction exposes lingo-cellulosic biomass to 250 to 350 C. Approximately 30 % increase in energy density, improved combustion particulars, 1/10 of milling energy requirement and improved water resistance are achieved results. Various torrefaction technologies are available. Pelleting or briquetting is obligatory for torrefied product transport. Numerous plants of app 1t/h are in operation; industrial-scale torrefaction lines are under construction.
