Synthesis gas from biomass can be produced and utilized in different ways. Conversion of biomass to synthesis gas can be done either in fluidized bed or entrained flow reactors. As gasification agent oxygen, steam, or mixtures are used. The most common use of biomass gasification in the last decades has been for heat and/or power production. Nowadays, the importance of transportation fuels from renewables is increased due to environmental aspects and growing fossil fuels prices. That is why the production of Fischer-Tropsch (FT) liquids, methanol, mixed alcohols, substitute natural gas (SNG), and hydrogen from biomass is now in focus of view. The most innovative and interesting ways of synthesis gas utilization and projects, BioTfueL or GoBiGas, BioLiq, Choren, etc. are discussed here. Further the microchannel technology by Oxford Catalysts and distributed production of SNG in decentral small scale are presented. The synthesis platform in Güssing, Austria is also presented. The FT liquids, hydrogen production, mixed alcohols, and BioSNG, these are the projects associated with the FICFB gasification plant in Güssing. Also the principle and examples of sorption-enhanced reforming to adjust H2/CO ratio in product gas during the gasification is described. Finally, in the conclusion also an outlook for the thermochemical pathway to transportation fuels is given.

Biomass Price Volatility - Analysis of the Historic Biomass and Energy Price volatility in the Austrian Market

Kristöfel C, Strasser C, Morawetz U, Schmidt J, Schmid E. Biomass Price Volatility - Analysis of the Historic Biomass and Energy Price volatility in the Austrian Market, 21st European Biomass Conference and Exhibition 2013, 3rd-7th of June 2013, Copenhagen, Denmark. p 1721-1727.

Details

Several energy and agricultural commodities have experienced higher price volatility in recent years. Hence, the interest in food and energy security issues as well as price volatility has increased, particularly since the rise in food and energy commodity prices in 2007/2008. Volatility is associated with risk since higher price volatility leads to additional costs that are often shared and transmitted along the supply chain to the final consumers. Volatility of woody biomass prices is also possibly higher due to increased market dynamics and integration as well as renewable energy policy intervention. We compute historic price volatility using the standard deviation of log returns as well as univariate GARCH models and empirically analyze whether or not price volatility of woody biomass commodities has increased in recent years. We also compare the historic price volatility of woody biomass to the price volatility of agricultural commodities and fossil fuels. Results indicate that the price volatility of some woody biomass commodities has increased, but it is still lower than of agricultural biomass and fossil fuels.

Nowadays prefabricated houses are becoming increasingly popular, thanks to their low cost and high energy performance. Heating systems installed in these houses should be carefully designed and controlled, to ensure sufficient thermal comfort while maintaining low fuel consumptions. This study presents the simulation of different system configurations and control strategies for a pre-fabricated house, located in Lower Austria. The house is heated by a 6 kW pellet boiler directly connected to a floor heating system, in a configuration without buffer storage tank. Using the TRNSYS simulation suite, a coupled simulation of the house and its heating and hot water supply system was set up, calibrated and validated with reference to monitoring data. As monitoring data evidenced that the control strategy of the heating system is not ideal to maintain a comfortable indoor temperature during the whole day, two improved strategies were simulated over the heating season and evaluated in terms of thermal comfort, pellet consumption and boiler’s efficiency. Moreover, to better understand the influence of the system configuration, simulations have been repeated considering another heat distribution system (radiators instead of floor heating). Results show that the radiators’ network, if adequately controlled, reduces by 85% the total discomfort time. In addition, the pellet boiler mainly operates in load modulation regime, leading to lower pellet supply rates and therefore to lower pellet consumptions (18% less than floor heating). However, the lower operational loads and frequent ignitions result in a slightly lower efficiency of the pellet boiler (4% less than the configuration with floor heating.
