China grid-scale energy storage: Outlook in 2012-2016

What's with the huge interest on China's RE initiatives?

Because it is fast becoming leader in renewables, and it has the world’s largest declared investment in renewable energy; no matter how you look at it. Rightly so because this year, China’s electric grid will become the largest in the world in terms of both installed generation capacity and electricity produced.

These facts, according to Greentechmedia, suggest that China is also the most attractive market for energy storage in the world, even though China currently has just 4% of the worldwide energy storage capacity. Japan has the largest installed energy storage capacity at 42% of the cake. This does not take into account pumped hydroelectric.

China's focus

Whereas other markets have focused on power quality and ancillary services, GTM noted that China’s grid energy storage market has developed with a focus on renewable energy integration, load-shifting and peak shaving. Azure International and GTM Research forecast that pumped hydro storage capacity will double or triple by 2016 to reach 40-60 GW, while other storage technologies will rise from currently insignificant levels to over 700 MW installed by 2016. Refer to the following Figure:

With strong government support and steadily improving technology, GTM anticipate the energy storage market will grow to a US$500 million per year market by 2016.

Glossary:

Energy storage - accomplished by devices or physical media that store energy  (potential energy or
                           kinetic energy) to perform useful operation at a later time.

Grid energy storage - a method used to store electricity on a large scale within an electrical power grid.

Pumped hydroelectric - a method used to stores energy in the form of water, pumped from a lower
                          elevation reservoir to a higher elevation. When electrical demand is high, the stored
                          water is released through turbines.

interesting! China and energy were topics in Mondays presidential debates here in the US

china is a good topic for both Obama and Romney, so it seem.
