Description
The objective of this research (conducted in WP5 of SCCER-Storage) is to develop a uniform techno-economic and environmental assessment method for electrical and thermal storage. This assessment is intrinsically flexible because it can be applied to different energy storage (ES) technologies for both heat and electricity, for different applications and sectors. As shown in Figure 1, the analysis will integrate different levels including:
• the storage unit, e.g. battery unit or hot water tank.
• the application, e.g. renewable energy (RE) time-shift and demand shifting.
• the system interactions, e.g. energy prices and reference scenarios.
Within WP5, a time-dependant analysis will be conducted including RE intermittency, ES dynamics, energy prices with tariffs and demand load profiles. In first instance we focus on electricity, based on SWISSIX data; later on, we address district heating. This analysis will be compared with a time-independent approach based on pre-defined ES systems and constant energy prices in order to understand the impact of the temporal resolution on the results. The outputs of this assessment method will be used to quantify the benefits of ES for the Swiss energy system and the profitability for investors.
Summary
A uniform techno-economic and environmental assessment methodology for electrical and thermal storage development and integration in Switzerland is presented. The analysis is time-dependant to take into account key dynamic parameters which affect the performance and value of energy storage. Different boundaries including the storage unit, application and system interactions are considered in the analysis.
