PublicationInteraction of energy storage technologies and synthetic fuels in long-term decarbonization scenarios( 2021)
;Heilig, JudithHaendel, MichaelWith the 2015 Paris Climate Agreement, the international community has reaffirmed its commitment to tackle anthropogenic climate change with the goal of limiting the global average temperature increase below 1.5 °C, but to a maximum of 2 °C above pre-industrial levels. Against this background, we examine scenarios for a complete decarbonisation of the European energy supply. Since such scenarios are based on a high expansion of weather-dependent renewable energy sources, the question arises, which flexible technologies are necessary to balance supply and demand in such energy systems. In this paper, a scenario analysis shows which capacity or volume of energy storage, power interconnectors and synthetic fuels are needed in decarbonization scenarios. To address this research question three different energy system models are applied. These models cover Europe and Germany, respectively, and are able to explain different results of the single models based of the corresponding model characteristics. The paper concludes that the power sector is able to cover a considerable share of the energy demand in the heat and transport sector with the help of flexible sector coupling technologies such as heat pumps and electric mobility. All considered models manage to find solutions for a deep decarbonization if flexibility and storage option are available. -

Publication7 Empfehlungen zum Gelingen der Energiewende(Fraunhofer-Gesellschaft, 2021)Die verschärften europäischen Klimaschutzziele und das neue deutsche Klimaschutzgesetz sind sehr ambitioniert und erfordern drastische und sofortige Maßnahmen. Zur Frage, wie diese am besten ausgestaltet sein sollten, hat das Fraunhofer Cluster of Excellence Integrated Energy Systems (CINES) sieben Empfehlungen für ein Gelingen der Energiewende erarbeitet.

PublicationMeshed HVDC transmission in the content of sustainable power transmission for the future and its environmental impact( 2014)
;Bohn, Sven ;Agsten, MichaelMarten, Anne-KatrinWhen talking about future power systems, power transmissions cannot be omitted. While it makes sense to generate RE where the potential is highest, it often means that volatile RE has to be transmitted over long distances. HVDC is favored for modern transmission to reinforce AC transmission. Around the world, HVDC is discussed and implemented in grid expansion plans. These plans range from point-to-point links towards meshed grids. This paper explores these grids and their ability to transmit RE in bulk and over long distances. It is shown to prevent massive AC grid expansion, and therefore positively impact the environment.
