1. The Global Market
As of the end of June 2018, the global capacity of electrochemical energy storage projects in operation totaled 3623.74MW, or 2.1% of the total capacity of all energy storage technologies, and an increase of 0.4 percentage points since the 2017 year’s end.
In the first half of 2018, global newly added electrochemical energy storage projects totaled 697.1MW, an increase of 133% from the same period the previous year, and 24% since the 2017 year’s end. In a regional comparison, the United Kingdom had the highest amount of newly installed capacity, at 307.2MW, or 44% of the total, an increase of 441% from the same period the previous year. In applications, ancillary services saw the highest growth in new capacity, at 354.2MW, or 51% of the total, an increase of 344% from the previous year. In technologies, Li-ion batteries were most widespread, with a total installed capacity of 690.2MW, or 99% of the total, an increase of 142% from the previous year.
2. The Chinese Market
As of the end of June 2018, China’s electrochemical energy storage projects in operation totaled 490.2MW, or 1.6% of the total of all energy storage technologies in the country, and an increase of 0.3 percentage points since the 2017 year’s end.
In the first half of 2018, China’s newly added electrochemical energy storage projects totaled 100.4MW, an increase of 127% from the previous year, and 26% since the 2017 year’s end. In a regional comparison, Jiangsu province saw the greatest increase in newly operational capacity at 25% of the total, a 996% increase since the end of the 2017 year. In applications, grid-side energy storage held the largest portion of capacity, at 42.6MW, nearly 45% of the total. In technologies, the vast majority of capacity was in Li-ion batteries, at 94.1MW, or 94% of the total, and increase of 172% compared to the same time the previous year.
