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…

Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was lab aged in dry and wet feed at different…

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 wastewater....

The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst for solid oxide fuel cell anode applications. Results of catalytic tests for the…

Co-impregnation of vanadia and tungsta on titania produced highly active catalysts for the reduction of nitrogen oxides with ammonia but showed aging tendencies at temperatures around 600°C. In order to preserve their low temperature activity after hydrothermal aging up to 650°C, the catalysts were…
