11. Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species
Abstract : Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. READ MORE

12. Residues from biochemical production of transport biofuels in Northern Europe : combustion properties and applications
Abstract : Residues from biochemical production of liquid transport biofuels will probably become available for energy use if more gasoline and diesel is substituted. For processes used in northern Europe they amount to 35-65 % of the feedstock energy and despite interest from energy companies, their fuel properties are largely unknown. READ MORE

13. Biogas production from lignocellulosic materials : microbial community structure
Abstract : Lignocellulosic materials such as agricultural plant residues are widely available in large amounts and can be used for production of biogas without the risk of competition for arable land. However, the intricate structure of lignocellulose, a major component of the plant cell wall, limits microbial degradation and consequently results in low degradation rate and low biogas yield.

14. Ash transformation in single-pellet combustion and gasification of biomass with special focus on phosphorus
Abstract : The utilization of different biomass feedstocks in thermal conversion systems can contribute towards mitigation of global warming. However, the formation of different ash fractions (i.e. READ MORE

15. Transformation and Release of Potassium, Chlorine, and Sulfur from Biomass under Conditions Relevant to Dual Fluidized Bed Gasification
Abstract : The transformation and release of ash-forming elements during thermal conversion of biomass areconducive to ash-related problems, for example, agglomeration of bed material in fluidized beds. Theoccurrence and severity of these problems largely depend on the extent to which K, Cl, and S arereleased from biomass during thermal conversion processes. READ MORE
