Lignin is one of the most promising sources of renewable aromatic hydrocarbons. Current methods for its extraction from lignocellulosic biomass—which include the kraft, sulfite, and organosolv processes—result in the rapid formation of carbon–carbon bonds, leading to a condensed…

The catalytic direct methanation of biogas to produce biomethane was conducted in a pilot plant with real biogas from a biogas plant in Zurich. Stable operation of the methanation system including a bubbling fluidised bed could be demonstrated for over 1100 h of regular…

An adsorption-based biogas cleaning system for deep desulfurization (<0.25 ppmv sulfur) was tested at pilot scale during a long-duration (1130 h) field demonstration. The goal was to protect a catalytic methanation reactor during direct methanation of biogas, where the biogas source was partly from a...

Catalytic methane oxidation is used in exhaust gas aftertreatment to reduce methane emissions from lean-burn natural gas vehicles as well as in stationary combustion processes. Pd/zeolite catalysts provide high activity for this reaction, but they deactivate rapidly under reaction conditions and in the presence of…

Swiss households invest less in energy-efficient appliances than would be optimal for achieving their energy targets. This is even the case when energy-efficient appliances have lower costs over their entire service life. A white paper from the SCCER CREST research center, where the University…

In Switzerland, regulatory powers in the field of energy policy are divided between the federal government, the cantons and the municipalities. An adequate division of tasks between these governance levels can support the transition to a more sustainable energy system. In the seventh SCCER CREST White Paper…
