With the establishment of a large number of clean energy power stations nationwide, there is an urgent need to establish long-duration energy storage stations to absorb the excess electricity produced by clean energy power stations and balance and adjust the power system .
In the course of energy transition, chemical-energy storage will be of significant importance, mainly as long-term storage for the power sector, but also in the form of combustibles and fuels for transport and heat.
Two million tons with a calorific value of around eight MW h/ton is equivalent to about 16 TW h of stored energy, 350 times the capacity of pumped-storage. This means that, apart from gas storage with 217 TW h of capacity, coal storage capacity is the largest in Germany. This again demonstrates the crucial role of chemical-energy storage.
A stationary Battery Energy Storage (BES) facility consists of the battery itself, a Power Conversion System (PCS) to convert alternating current (AC) to direct current (DC), as necessary, and the “balance of plant” (BOP, not pictured) necessary to support and operate the system. The lithium-ion BES depicted in Error!
With each facility ranging in the terawatt-hours, chemical energy storage has by far the largest capacity. It is also the only option for seasonal energy storage using the charging technology power-to-gas in combination with the existing gas infrastructure for storing and converting gas into electricity.
Another option with chemical energy storage is to convert electricity into basic chemical materials (methanol) or liquid fuels (power-to-liquid). These liquid fuels would be particularly useful in transport segments requiring high energy densities such as aviation (Fig. 11). Fig. 11.
