Demand for battery back-up in data centers : Lithium-ion growing, but lead-acid systems still dominate

Data centers are the major purchasers of lead-based batteries which improve the power quality and provide instantaneous back-up power. This is a rapidly growing market: demand for battery back-up in data centers across North America and Europe will quadruple between 2016 and 2025, rising from 3.5 to 14 gigawatt-hours, according to a new report by the research firm Bloomberg New Energy Finance.

This clearly shows that lead-acid systems will likely remain the dominant and low-cost solution for UPS energy storage, at least in the short term.

Lithium-Ion batteries, widely used in consumer electronics, including smartphones, and electric cars, have just started being adopted for energy storage in data center backup systems. But the report estimates that this technology will take off in the coming years with a market share increasing from 1 to 35 percent over just a few years.
