What is an Emerging Biofuel?

Within biofuels, examples of emerging technologies are: torrefaction to produce biocoal slow pyrolysis to produce biochar fast pyrolysis to produce pyrolysis oil and biochar hydrothermal carbonization to produce hydrochar hydrothermal liquefaction to produce biocrude stream treated to produce black pellets gasification to produce producer gas and/or syngas. With such early-stage ventures, an important early task […]

The Industrial State of Biofuels Technologies

By Dr. Gerald Kutney, Lee Enterprises Consulting A myriad of biofuel technologies exist, but which ones are truly industrial processes? The question is not always easy to answer. And one must define what is meant by an industrial process. To facilitate this task, three classifications of industrial status are utilized: Established – modern facilities are numerous, […]

Torrefied Biomass: Available, Efficient, CO2 Neutral and Economic – Likely the Best Solid Biomass on the Market

Torrefaction is a thermal pre-treatment technology used to upgrade lignocellulosic biomass to a higher quality and more attractive biofuel. In the torrefaction process, biomass is heated to 250-350°C in a low oxygen atmosphere, so that all moisture is removed and the biomass is partly devolatilises leading to a decrease in mass. Most of the initial […]

Why and When You Need a Project Consultant

As the CEO of the world’s largest bioenergy consulting group, I am fortunate to have a unique opportunity to view alternative fuels projects from many different perspectives. Within our group, now numbering over 75 experts, I find that each member has his or her own approach which developed from their personal experience and training. As […]

A Short History of Biofuels

Introduction In the modern world, fuels are often equated with fossil fuels:  coal, oil and natural gas.  However, fossil fuels only came into their own during the 20th century.  From the time of the caveman until the early Industrial Revolution, biofuels – namely wood and the advanced biofuel of the day, charcoal – reigned supreme.  […]

What is Torrefaction?

Among the biomass-based products available for the direct replacement of coal for electricity generation are mechanically-treated wood (hog fuel or wood chips), wood pellets, torrefied wood and biocarbon. Wood pellets are widely used, especially in Europe. A major drawback is the poor water resistance of the pellets. Unlike coal, wood pellets must be protected from […]
