« This is incredibly ambitious »

Every three years, the World Energy Council explores possible developments of the global energy system under different scenarios. Tom Kober, head of the Energy Economics Group at PSI and one of the lead authors of the study, explains what the individual projections mean and how global warming could be mitigated. Since 2010, the World Energy Council has been developing these World Energy Scenarios and publishing them every three years…

Cu–Al Spinel as a Highly Active and Stable Catalyst for the Reverse Water Gas Shift Reaction

The reverse water gas shift reaction is considered to be a highly attractive catalytic route for CO2 recycling in a future sustainable economy. Copper-based catalysts are commonly used for this reaction due to their high activity and selectivity. However, their low thermal stability is problematic for long-term usage. Here, we introduce an in situ formed…

Scale-up methodology for automatic biomass furnaces

This work presents a methodology to perform the scale-up of a solid fuel furnace to a higher heat output with maintaining or improving the burn-out quality. As basis to derive the scale-up concept, an example of a 35 kW screw burner for biomass fuels is investigated. Based on the Pi-theorem, the relevant dimensionless parameters are derived and similarity rules for the…

A combined hydrothermal gasification – solid oxide fuel cell system

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system operating without external connection to sewer pipes was used as a feedstock for HTG process. The leachate effluent was characterized…
