Morihara’s company announced it has refined a process for turning logging slash or other biomass into briquettes that can be burned in coal-fired electrical plants such as the one in Boardman, Ore. His company, HM3 Energy Inc., has built a $4 million demonstration plant in Troutdale, Ore., just east of Portland. It plans to license the technology and sell it worldwide. A Japanese firm, New Energy Development Co., has invested $2 million in HM3 and said it will build a production plant at an undisclosed location in Oregon.
The fuel is produced through a method called torrefaction, in which woody debris, crop residue or other plant material is essentially roasted in the absence of oxygen. The end product is a brittle, briquette-looking material that can be crushed and burned.
