Torrefaction is a thermal conversion method of biomass used to produce a high-quality solid biofuel that can be used for combustion, gasification, and additional non–energy-related applications. Torrefied biomass has numerous advantages above today’s standard biomass fuels like log wood, wood chips, and white wood pellets (WWPs). This is known and promoted for long, and has been proven in numerous research and demonstration projects; however, large-scale industrial proof is still underway only in these days. First, project implementations with name plate capacity of 100 kmt/a or higher are in construction or hot commissioning. In this review, the main advantages of torrefaction are shortly described, and the latest industry developments and future opportunities for the products as well as areas of need for further R&D are presented.
