TL;DR: In this article, a simulation model that investigates the economic viability of battery storage for residential PV in Germany under eight different electricity price scenarios from 2013 to 2022 is presented. And the model with a large number of different PV and storage capacities is run to determine the economically optimal configuration in terms of system size.
Abstract: Battery storage is generally considered an effective means for reducing the intermittency of electricity generated by solar photovoltaic (PV) systems. However, currently it remains unclear when and under which conditions battery storage can be profitably operated in residential PV systems without policy support. Based on a review of previous studies that have examined the economics of integrated PV-battery systems, in this paper we devise a simulation model that investigates the economic viability of battery storage for residential PV in Germany under eight different electricity price scenarios from 2013 to 2022. In contrast to previous forward-looking studies, we assume that no premium is paid for solar photovoltaic power and/or self-consumed electricity. Additionally, we run the model with a large number of different PV and storage capacities to determine the economically optimal configuration in terms of system size. We find that already in 2013 investments in storage solutions were economically viable for small PV systems. Given the assumptions of our model, the optimal size of both residential PV systems and battery storage rises significantly in the future. Higher electricity retail prices, lower electricity wholesale prices or limited access to the electricity wholesale market add to the profitability of storage. We conclude that additional policy incentives to foster investments in battery storage for residential PV in Germany will only be necessary in the short run. At the same time, the impending profitability of integrated PV-storage systems is likely to further spur the ongoing trend toward distributed electricity generation with major implications for the electricity sector.

TL;DR: In this paper, the authors investigated the impact of uncertainty in input parameters on battery lifecycle costs and concluded that the present uncertainty in cost and technical parameters of batteries exceeds by far the differences in battery lifetime across technologies.
Abstract: In future electricity systems with a high share of intermittent renewable power generation, battery technologies have the potential to support power quality and security. The growing scientific literature on batteries reflects the high attention that currently rests on these technologies. This paper reviews the existing literature on lifecycle costs of batteries in stationary applications. The primary result of this review is that, despite the current high degree of variance in technological and economic battery data, a systematic assessment of the underlying uncertainty is lacking. The present paper addresses this disparity with an investigation of the impact of uncertainty in input parameters on lifecycle costs of four battery technologies across six electricity system applications. Based on input data collected from literature and via expert interviews, a probabilistic techno-economic model was built that calculates lifecycle costs and systematically addresses uncertainty in input parameters by applying a Monte Carlo simulation. The main conclusion of this paper is that the present uncertainty in cost and technical parameters of batteries exceeds by far the differences in lifecycle costs across technologies. For most electricity storage applications, the absolute differences in mean lifecycle costs across technologies are negligible compared to the uncertainty ranges of the mean lifecycle costs. Therefore, a competition still exists between the four analyzed battery technologies and so far a leading technology has yet to emerge in any of the investigated applications.

TL;DR: The Oxford Handbook of Innovation as mentioned in this paper provides a comprehensive and holistic understanding of the phenomenon of innovation, with a focus on firms and networks, and the consequences of innovation with respect to economic growth, international competitiveness, and employment.
Abstract: This handbook looks to provide academics and students with a comprehensive and holistic understanding of the phenomenon of innovation. Innovation spans a number of fields within the social sciences and humanities: Management, Economics, Geography, Sociology, Politics, Psychology, and History. Consequently, the rapidly increasing body of literature on innovation is characterized by a multitude of perspectives based on, or cutting across, existing disciplines and specializations. Scholars of innovation can come from such diverse starting points that much of this literature can be missed, and so constructive dialogues missed. The editors of The Oxford Handbook of Innovation have carefully selected and designed twenty-one contributions from leading academic experts within their particular field, each focusing on a specific aspect of innovation. These have been organized into four main sections, the first of which looks at the creation of innovations, with particular focus on firms and networks. Section Two provides an account of the wider systematic setting influencing innovation and the role of institutions and organizations in this context. Section Three explores some of the diversity in the working of innovation over time and across different sectors of the economy, and Section Four focuses on the consequences of innovation with respect to economic growth, international competitiveness, and employment. An introductory overview, concluding remarks, and guide to further reading for each chapter, make this handbook a key introduction and vital reference work for researchers, academics, and advanced students of innovation.
