The deployment of battery-powered electric bus systems within the public transportation sector plays an important role to increase energy efficiency and to abate emissions. Rising attention is given to bus systems using fast charging technology. This concept requires a comprehensive...

In this Essay, I reflect on the different ways in which cities engaged in what I call “infrastructure sharing” during the COVID-19 pandemic. Cities around the world responded to the pandemic by repurposing their streets and sidewalks into outdoor seating, dining spaces, and car-free...

Empirical work on the causal effect of government fragmentation finds diversified results. This might be explained by the fact that studies typically are settled in different institutional environments. To assess in how far the political system might shape the effects of fragmentation, this...

Scenarios of future energy systems attribute an important role to Carbon Capture, Transport, and Storage (CCTS) in achieving emission reductions. Using captured CO2 for enhanced oil recovery (CO2-EOR) can improve the economics of the technology. This paper examines the potential for CO2-EOR in...
