Grid-scale Energy Storage: Lux Predicts $113.5 Billion in Global Demand by 2017

Last month Lux Research released a bottom-up evaluation of the cost effectiveness of eight energy storage technologies in six grid-scale applications throughout 44 countries, including all 50 U.S. states. Their report titled “Grid Storage under the Microscope: Using Local Knowledge to Forecast Global Demand” predicts that annual global demand for grid-scale energy storage will reach an astounding 185.4 gigawatt-hours (GWh) by 2017 and represent a $113.5 billion incremental revenue opportunity for an industry that currently generates sales of $50 to $60 billion a year.

In the grid-scale sector alone, Lux predicts an average year-on-year demand growth of 231 percent from 2012 through 2015 when the growth rate moderates to 43 percent per year for 2016 and 2017. The forecast is tempered, however, by a cautionary note that demand of that magnitude can’t be satisfied because “Believe it or not, the grid storage market will be supply-constrained in 2017.”

Technologies and players

The eight energy storage technologies Lux evaluated for their new report are summarized in the following table, along with the price and performance metrics highlighted in beige. Comparable price and performance metrics from a recent Sandia National Laboratories “Energy Storage Systems Cost Update” are also presented and highlighted in green. While there’s room to quibble over the details and users of Lux’s Smart Grid Storage Tracker and Demand Forecaster can fine tune the price and performance variables to suit their analytical needs, the parallels between the two sets of system cost estimates are close enough to lend substantial credence to Lux’s basic assumptions.
