Heat pumps are a key technology for reducing fossil fuel use in the heating sector. A transition to heat pumps implies an increase in electricity demand, especially in cold winter months. Using an open-source power sector model, we examine the power sector impacts of a massive expansion of decentralized heat pumps in Germany in 2030, combined with buffer heat storage of different sizes. Assuming that ...
The energy crisis and the accelerated transition to climate neutrality result in a shift from the traditional energy trilemma to an “energy quartet” across Europe. Firstly, the criteria of affordability, previously focused on short-term price developments, broadens to reliable affordability including in crises. Secondly, clean energy traditionally focused on clean production now extends to clean energy ...
Ein frohes neues Jahr wünschen euch Wolf und Alex! Was ihr schon immer zur Energiewende wissen wolltet, aber nie zu fragen gewagt habt – hier ist der zweite Teil unserer Antworten. Da wir nicht alle Fragen in einer Episode beantworten konnten, gehen wir hier im Teil 2 besonders auf die Themen Elektromobilität und Wärmepumpen ein. Wie auch schon beim letzten Mal gilt: ganz einfache Antworten gibt...
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 ...
