Aim: The aim of this paper is to explore Energy Storage requirements and options to suit the needs of systems and transport fed from renewables. The variability of wind and solar sources in particular and the demand for transport energy are seen as key issues. Design / Research methods: The...

The final version of this paper will appear as Chapter 6 in the forthcoming MIT Energy Initiative study, The Future of Storage. Chapters referred to in this paper will be included in that study when it is published. In order to illuminate the role of energy storage in future decarbonized...

For decades, the Greek islands have been facing challenges in terms of quality of power supply, increased carbon dioxide equivalent (CO2eq) emissions, and costs due to their reliance on oil-fired generation subsidised by the Greek state. In light of the recent reforms to decarbonise the islands'...

In the transition to decarbonized energy systems, Power-to-Gas (PtG) processes have the potential to connect the existing markets for electricity and hydrogen. Specifically, reversible PtG systems can convert electricity to hydrogen at times of ample power supply, yet they can also operate in...

The pace of the global decarbonization process is widely believed to hinge on the rate of cost improvements for clean energy technologies, in particular renewable power and energy storage. This paper adopts the classical learning-by-doing framework of Wright (1936), which predicts that cost will...

In the context of 100% renewable electricity systems, prolonged periods with persistently scarce supply from wind and solar resources have received increasing academic and political attention. This article explores how such scarcity periods relate to energy storage requirements. To this end, we...

DIETER is an open-source power sector model designed to analyze future settings with very high shares of variable renewable energy sources. It minimizes overall system costs, including fixed and variable costs of various generation, flexibility and sector coupling options. Here we introduce...

Green hydrogen can help to decarbonize parts of the transportation sector, but its power sector interactions are not well understood so far. It may contribute to integrating variable renewable energy sources if production is sufficiently flexible in time. Using an open-source co-optimization...

The U.S. residential energy storage market grew rapidly during 2017–20, driven by homeowners seeking to increase resiliency, changes in net metering programs, and the financial benefits of installing a system. The residential energy storage system (ESS) market was dominated by Tesla in 2020...

Secure and reliable operation of power systems with high wind and solar shares requires system flexibility. In this paper, an hourly-based market and grid simulation model is developed to assess security and reliability of a power system with high wind and solar energy share. The model is...

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 growing concern about decarbonization of the energy production system led to the use of Renewable Energy Sources (RES). However, RES has the drawback of being inherently intermittent and lack controllability, placing limitations on their use. To avoid such limitations, the exploitation of a...

This paper studies the bidding strategy of a Virtual Power Plant (VPP) in a market of energy and regulation service. The operation of distributed energy resources (DER) and battery energy storage inside the VPP is analyzed. A bidding strategy of the VPP including the spinning reserve contract...

Using electricity for heating can contribute to decarbonization and provide flexibility to integrate variable renewable energy. We analyze the case of electric storage heaters in German 2030 scenarios with an open-source electricity sector model. We find that flexible electric heaters generally...

Die Energiewende in Deutschland erfordert neben neuen Übertragungsleitungen für regenerativ erzeugten Strom auch den Bau neuer Speicherkraftwerke. Für das bei Trier geplante Pumpspeicherkraftwerk Rio wurde 2012/2013 ein Raumordnungsverfahren durchgeführt. Der folgende Beitrag dokumentiert...

Although electricity supply is still dominated by fossil fuels, it is expected that renewable sources will have a much larger contribution in the future due to the need to mitigate climate change. Therefore, this paper presents a new framework for developing Future Electricity Scenarios...

The calculation of unit cost that can be used for estimating capacity investment decisions is frequently ambiguous due to the many ways to apportion applicable cash ows connected to the delivery of products. This paper studies the identification of relevant unit cost when productive capacity is...
