摘要：Biomass is a non-intermittent energy source, which can play an important role in grid-based energy systems, since they need some non-intermittent sources in order to balance variability of intermittent sources as wind and solar energy. Currently this role is played by mostly by fossil fuels, mainly because of the bulk size of a single source. Higher variability and lower energy concentration among with some properties of biomass are obstacles that prevent it from fully becoming a commodity. There are processes, such as dry torrefaction and hydrothermal carbonization (HTC) that could potentially help in terms of making biomass tradable commodity as it is a case with fossil fuels. HTC, also known as wet torrefaction, might help to solve problems that dry torrefaction is unable of solving. These obstacles are namely high ash content, slagging and fouling properties of biomass (along with corrosion). Also high moisture content of some types of biomass is a problem, since they usually require substantial amounts of heat for drying. This paper reviews current knowledge about fundamentals of the process that could possibly enable problematic types of biomass to become a tradable commodity.
