Abstract
Dette speciale undersøger, om Carnot-batterier—en type energilager, der lagrer elektricitet som varme og senere omdanner den tilbage til el—er teknisk og økonomisk realistiske i Tyskland. Med udgangspunkt i begreberne carbon lock-in (tendensen til at fossile systemer fastholdes af infrastruktur, investeringer og regler) og multi-level perspective (en ramme, der forklarer, hvordan nicheteknologier kan vokse og blive almindelige), peger analysen på et vindue af muligheder, hvis der kan findes et levedygtigt marked. For at undersøge, hvor et sådant marked kan opstå, analyserede vi elsektoren ved at modellere og optimere 21 scenarier med EnergyPLAN (en energisystemmodel) kombineret med Matlab. Resultaterne peger på et lovende potentiale for at bruge Carnot-batterier til at ombygge eksisterende kulfyrede kraftværker.
This thesis examines whether Carnot batteries—a type of energy storage that stores electricity as heat and later converts it back to power—are technically and economically feasible in Germany. Drawing on carbon lock-in (the tendency for fossil-based systems to persist because of infrastructure, investments, and rules) and the multi-level perspective (a framework for how niche technologies can move into the mainstream), the study identifies a window of opportunity if a viable market can be found. To explore where such a market could emerge, we analyzed the power sector by modeling and optimizing 21 scenarios using EnergyPLAN (an energy system modeling tool) combined with Matlab. The results indicate a promising case for using Carnot batteries to retrofit existing coal-fired power plants.
