The German government cabinet has approved a draft law that would allow the underground storage of CO2 and enable its large-scale transport through pipelines, and thus pave the way for the application of carbon capture and storage or utilisation (CCS, CCU) across the country.
Why should Germany use energy storage systems?
Germany is under increasing pressure to rapidly decarbonize its electricity system, while ensuring a secure and affordable electricity supply. In this context, energy storage systems (ESSs) can play a crucial role in enabling a high share of variable renewable electricity generation.
Who uses battery storage systems in Germany?
A large number of players are active in these fields, including suppliers of battery storage systems. In addition, utilities, car manufactures and energy intensive industries are active on the German market to use large scale battery storage systems or second life and replacement batteries for cars as primary reserve in the control energy market.
What are the business cases of energy storage?
Three business cases are explored in more detail: the contribution of a large-scale energy storage to frequency regulation, the optimisation of self-consumption of PV electricity combined with an energy storage system and the participation of energy storage in spot markets.
Can pumped hydro storage be a key component of Germany's electricity system?
The study by Keles and Yilmaz, for instance, considers only the option of pumped hydro storage (PHS), as it is already a key component of the German electricity system. Others consider multiple technology options, with Bartholdsen et al., for instance, considering also lithium-ion batteries and hydrogen storage (via power-to-gas).
What role does energy storage play in China?
Energy storage systems play an important role in China. By the end of 2018, China had approximately 30 GW of pumped storage power plants and 1 GW of electrochemical storage (batteries) installed. China's government plans to push ahead with the expansion of battery storage facilities for further RES grid integration.
How is Germany transforming the energy system?
In addition to the complexity of transforming the German electricity system, climate-related targets and policies have been tightened substantially. The newest amendment of the Renewable Energy Sources law requires renewable energy sources to cover at least 80% of the annual electricity consumption in 2030.
