China blazes cleantech trail, builds world's largest battery

China has lifted the lid on what's said to be the world's largest battery, capable of storing 36 megawatt-hours of electricity.

To give you an idea of the magnitude, PopSci calculates that this is sufficient to power something like 12,000 houses for an hour during a total power failure.

China has been busy building a name for itself in cleantech, and this facility is a joint venture between the State Grid Corporation of China (SGCC) and electric car maker BYD, integrating a solar project and wind farm into a smart grid.

While there are renewable generation systems of this scale in service today, there are no battery systems of this size, according to SGCC.

The world’s largest energy storage device consists of batteries “larger than a football field,” and is expected to increase the region’s renewable energy efficiency by up to 10 percent.
