Measuring the producer gas from biomass gasification is very challenging and the use of several methods is required to achieve a complete characterization. Various techniques are available for these measurements, offering very different affordability or time demand requirements and the reliability of these techniques is often unknown. In this work...

Most industrial fixed-bed biomass gasification systems usually operate at steady-state to produce the maximum amount of energy possible although they can principally modulate their loads to compensate for the fluctuations of other volatile renewable energy systems. To unleash their full load modulation capability, their typically traditional contro...

Compared to extensive studies on affecting parameters in sulfur removal with ZnO adsorbents from coal gasification syngas, similar studies conducted for biomass gasification syngas (BGS) are quite rare. Thus, considering the BGSs with high water content, this study was performed to investigate the effect of H2O presence in syngas on sulfur removal...

Solid oxide fuel cells are a promising alternative to gas engines for combined heat and power production based on biomass gasification. The technical complexity of realizing gasifier – fuel cell couplings has limited the number of experiments conducted in the past. However, results from such experiments are of high importance for the evaluation of...

Fixed-bed biomass gasification is a promising dispatchable option of renewable energy sources to serve flexibility demands in electricity production. To experimentally investigate this potential, this contribution analyses an industrial small-scale fixed-bed biomass gasification system for demand-oriented electricity production by evaluating the ef...

Fixed-bed biomass gasification coupled with internal combustion engines allows an efficient exploitation of biomass for the combined production of heat and power (CHP) at small scale with increased economic viability with respect to combustion-based CHP systems. The main barrier on the way towards a wider market distribution is represented by the f...

Assessing the operational behaviour of biomass gasification systems is a crucial basis for further improvements in terms of operational behaviour and robustness in order to increase the technologies’ operational and economic viability. However, in most fixed-bed biomass gasification systems not all parameters required for the assessment can be meas...

In the Austrian project UseCO2 – Utilisation of CO2 from industry experts from research institutes, universities, iron and steel industry and energy sector developed novel concepts for CO2 utilisation. For the conversion of CO2 to value added products a large number of different thermochemical and biotechnological pathways exist. The project identi...

Investigations of cellular processes initiated by volatile organic compounds (VOCs) are limited when modelling realistic long-term exposure scenarios at low concentrations. Exposure to indoor VOCs is associated with a range of adverse effects, but data on molecular changes at regulatory threshold limits are lacking. Activity analysis of VOC in vitr...

In the last years sampling at various gasification plants has been performed at Bioenergy2020+. The equipment, which is based on the recommendations of the tar guideline, has been further developed and adjusted to specific needs. For an evaluation of the procedure different parts of the equipment were tested with a new developed gas¬ generating uni...

In biomass-gasification based energy systems (CHP, polygeneration) high overall efficiency are essential for competitive operation. Producer gas impurities reduce activities or damage expensive catalysts, which are used in modern energy conversion processes. Therefore a cheap and efficient gas treatment at process-related high temperature level is...
