How Can Low-Carbon Energy Dematerialize the Economy? Technological Transitions and the Political Economy of Electricity Generation
This dissertation addresses features of the displacement paradox in the context of electricity generation, both at the cross-national level and within one region of the United States. The displacement paradox is the empirical phenomenon of substitutes to a specific product, here fuels used to …

The value of pumped hydro storage in a decarbonized world
Countries around the world have pledged to decarbonize their electricity sector in order to address climate change. In this thesis we investigate the role of pumped hydro storage (PHS) in decarbonizing power generation in combination with a high penetration of low-carbon energy sources. PHS is the …

Conceptual design and performance characteristics of firebrick resistance-heated energy storage for industrial heat supply and variable electricity production
Concerns of climate change and sustainable energy policy are driving the deployment of wind and solar energy towards the goal of reducing fossil fuel emissions. In liberalized (deregulated) markets, the large-scale deployment of wind or solar energy results in electricity price collapse at times of …

The energy business system: transformation, social innovation & disruptive smart grid business models
A radical shift from a high- to a low-carbon energy system is not occurring at the speed required to address climate change. One reason for this, is that conventional energy firms are locked into producing shareholder profit with fossil-intensive business models that are still operable in current …
