Cost of renewable energies have dropped, approaching wholesale power price levels. As a result, the role of renewable energy policy design is shifting – from covering incremental costs towards facilitating risk-hedging. An analytical model of the financing structure of renewable investment projects is developed to assess this effect und used to compare different policy design choices: contracts for ...
Die Mehrheit der Deutschen kann in der Krise nicht sparen und 40 Prozent konnten es schon vorher nicht: Die Politik muss handeln, sonst zerbricht der Sozialstaat. 60 Prozent der Deutschen können in dieser Krise nicht sparen – so die erstaunliche Zahl, die diese Woche viel Aufmerksamkeit erregt hat. Dabei ist dieser Befund gar nicht überraschend, haben doch fast 40 Prozent der ...
In this article, we provide the results of a simple quantitative analysis of the potential remedies to reduce the supply gap in Germany that arises if Russia stops delivering natural gas. We take into account the supply potential of other suppliers, and combine this with an analysis of the additional supply potential by stopping electricity generation from natural gas. Moreover, we investigate the ...
The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...
The current governance process to plan the German energy system omits two options to substitute grid expansion: First, placing renewables closer to demand instead of where site conditions are best. Second, utilizing storage instead of additional transmission infrastructure to prevent grid congestion. In the paper, we apply a comprehensive capacity expansion model based on the AnyMOD modeling framework ...
