Project 2: Energetically significant evaluation and optimisation of long-term energy-storage-systems

An environmentally friendly, safe and competitive energy supply includes the power market as well as the heat market for all energy sectors. Considering these forms of energy as goods, which can be both imported and exported, is essential from the perspective of globalisation and inclusion of other states. Several forms of efficient energy storage are necessary with regard to a future energy supply with low CO2 emissions, which should be affected by social acceptance. This project pursues the objective of a holistic assessment of selected storage systems. Challenges, opportunities and development potentialities relating to energy storage are to be analysed at the interface of energy supply also concerning central and peripheral options. Furthermore, it must be pointed out that future low-emission energy systems are not only electric power, but also thermal energy, which needs to be at least partially provided by fluctuating energy sources. The transport sector and chemical energy sources are also taken into account. The objective of this particular project is a holistic analysis of an appropriate selection of long-term energy storage technologies considering the seasonal supply and demand situations. Several storage technologies that are already available today or in development will be investigated and evaluated with an interdisciplinary approach at the Boysen-TU Dresden-Graduiertenkolleg in terms of technical and economic feasibility, ecological impact and social acceptance. The Focus of this study is the long-term storage capability of chemical and thermal storage systems. Power-to-heat and power-to-gas/liquid concepts as well as options for the utilisation of waste heat energy are also included. These energy storage systems seem to be promising from today’s point of view.
