Opportunities and challenges of high renewable energy deployment and electricity exchange for North Africa and Europe - scenarios for power sector and transmission infrastructure in 2030 and 2050

2016 , Boie, Inga , Kost, Christoph , Bohn, Sven , Agsten, Michael , Bretschneider, Peter , Snigovyi, Oleksandr , Pudlik, Martin , Ragwitz, Mario , Schlegl, Thomas , Westermann, Dirk

Climate change and limited availability of fossil fuel reserves stress both the importance of deploying renewable energy sources (RES) for electricity generation and the need for a stronger integration of regional electricity markets. This analysis focuses on North African (NA) countries, which possess vast resources of renewable energy but whose electricity supply is still largely dependent on fossil fuels. An analysis of cost-optimized deployment scenarios for RES is conducted in five NA countries in 2030 and 2050. Three electricity models are combined to derive results covering trans-regional to sub-national level, including a detailed analysis of grid capacities and future transmission challenges. Further, opportunities for integration of European and NA electricity markets are evaluated. Results confirm that, by 2050, high RES shares - close to 100% - are possible in NA. Wind energy is the dominant technology. Concentrated Solar Power (CSP) plants also play an important role with rising RES shares due to the possibility to store thermal energy. Electricity exports to Europe gain particular importance in the period after 2030. Substantial transmission grid reinforcements on AC-level and the construction of a high voltage DC overlay grid are prerequisites for the forecasted scenarios.

Hydrogen technologies in energy systems

2022 , Bard, Jochen , Gerhardt, Norman , Plaisir, Marie , Schröer, Ramona , Held, Anne , Henning, Hans-Martin , Kost, Christoph , Pfluger, Benjamin , Ragwitz, Mario , Reuter, Andreas

This chapter compares the role of hydrogen and synthetic energy carriers in energy systems and discusses certain aspects of them. To this end, we have examined systemic studies that consider the existing interactions between demand, production, facility locations and the construction and use of power, gas and heating networks.

Einsatz von Wasserstofftechnologien im Energiesystem

2022 , Bard, Jochen , Gerhardt, Norman , Plaisir, Marie , Schröer, Ramona , Held, Anne , Henning, Hans-Martin , Kost, Christoph , Ragwitz, Mario , Pfluger, Benjamin , Reuter, Andreas

Das Kapitel vergleicht die Rolle von Wasserstoff und synthetischen Energieträgern im Energiesystem und diskutiert ausgewählte Aspekte. Hierfür wurden Systemstudien herangezogen, die bestehendeWechselwirkungen zwischen Nachfrage, Erzeugung, räumlicher Verortung der Anlagen und den Aufbau und die Nutzung von Strom-, Gas- und Wärmenetzinfrastruktur berücksichtigen.
