Cost reductions of rooftop photovoltaics and battery storage, increasing retail electricity prices as well as falling feed-in remuneration provide strong incentives for many German households to engage in self-consumption. These developments may also affect the electricity system as a whole....

The recent advances in battery technology and reductions in battery costs have brought battery energy storage systems (BESS) to the point of becoming increasingly cost-effective projects to serve a range of power sector interventions, especially when combined with PV and where diesel is the...

Growing shares of renewable energy sources (RES) in the electricity system increase the need for flexible balancing of supply-dependent feed-in of RES and time-varying demand. Besides flexible, conventional technologies and demand-responses, storage is an important option. Through the use of an...

The paper analyzes the problem of achieving a target path of emission reductions in the electricity sector, using a scheme of tradable green certificates (TGC). There are two types of generation, renewable and fossil. The latter causes the emissions. The paper also examines effects from emission...

Mitigating climate change will require integrating large amounts of highly intermittent renewable energy (RE) sources in future electricity markets. Considerable uncertainties exist about the cost and availability of future large-scale storage to alleviate the potential mismatch between demand...

Eine Elektrifizierung bzw. die Kopplung des Stromsektors mit dem Verkehrssektor spielt in allen Technologie­szenarien eine Schlüsselrolle in der Reduktion von THG-Emissionen. Viel Aufmerksamkeit ist hier der Elektrifizierung von Pkw zugekommen. Weniger im Fokus standen Schwer- und...

Starting from a low level, in recent years the battery-supported self-consumption of solar electricity (solar prosumage) has grown significantly in Germany. Its growth is primarily due to the opposing trends in household electricity prices and feed-in tariffs in conjunction with government...

The climate targets defined under the Paris agreement of limiting global temperature increase below 1.5 or 2°C require massive deployment of low-carbon options in the energy mix, which is currently dominated by fossil fuels. Scenarios suggest that Carbon Capture and Storage (CCS) might play a...

Die voranschreitende Digitalisierung führt in vielen Sektoren zu einer verstärkten Einbindung von Haushalten und dadurch zu neuen dezentralen Softwareanwendungen. In der Energiewirtschaft, insbesondere im Stromsektor, verlangt zusätzlich der kontinuierliche Ausbau dezentraler...

Wie kann der erhöhte Anteil durch Photovoltaik und Windkraft fluktuierend erzeugter Energie im Stromnetz ausgeglichen werden? Biogas- und Biomethananlagen sind interessante technologische Lösungen zur Stabilisierung des Stromnetzes. Die Umsetzung der Biomasse zu Methan erfolgt aber aufgrund...

Based on German hourly feed-in and consumption data for electric power, this paper studies the storage and buffering needs resulting from the volatility of wind and solar energy. It shows that joint buffers for wind and solar energy require less storage capacity than would be necessary to buffer...

We analyze the role of electricity storage for technological innovations in electricity generation. We propose a directed technological change model of the electricity sector, where innovative firms develop better electricity storage solutions, which affect not only the relative competitiveness...

In the electricity sector, innovation in large-scale storage is anticipated to reduce costs and improve performance. The effect on greenhouse gas emissions of lower storage costs depends on the interactions between storage and the entire grid. The literature has disagreed on the role of storage...
