What are the Sino-European industrial energy storage systems

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.

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.

How are energy storage systems accelerating balancing power in Germany?

Until now, it has mainly been CO2-intensive power stations that have been used for this primary balancing power; these networked residential energy storage systems are helping accelerate the removal of these power stations from the grid in Germany.

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.

What are the different types of energy storage options?

Mechanical energy storage (with a focus on the dominant pumped hydro storage). Electro-chemical storage (both in large-scale and small-scale options, as well as options where electric vehicles provide services to the grid). Chemical storage, with a focus on the innovative and forthcoming storage options based on hydrogen (PtX) and synthetic gas.

Why is energy storage important in Germany?

Balancing the rising share of intermittent renewables calls for new solutions and business models. In Germany, energy storage has experienced a dynamic market environment in recent years, particularly for providing ancillary services, and in home applications. This report sheds light on the important topic of energy storage.
