EnerSys has launched DataSafe Noir, a lithium-based energy storage system specifically designed for data centres facing higher density, more variable workloads and growing demand from AI applications.
Unlike some of its competitors, EnerSys is choosing to focus on how the DataSafe Noir can deliver more predictable power performance under real world conditions rather than simply comparing batteries by chemistry, runtime or cost.
That could become increasingly important as data centres continue to support AI and high-performance computing workloads, which can place more dynamic demands on critical power infrastructure. While backup power has always been central to data centre resilience, the challenge is no longer just having enough stored energy available, but ensuring that energy systems behave consistently when placed under stress.
According to EnerSys, DataSafe Noir has been designed as an integrated system, supporting more consistent deployment and defined operating performance in high-density environments. The company claims the system delivers more than twice the output power and more than 1.7 times the energy and capacity compared to publicly available specifications for leading lithium systems.
If borne out in deployment, that could help operators reduce the amount of data centre floor space required for energy storage, which is becoming a more pressing concern as facilities are asked to accommodate more compute capacity within existing footprints.
A growing role for lithium
EnerSys has been historically associated with products such as its DataSafe Thin Plate Pure Lead battery technology. While the company has long argued that there continues to be a place for other batteries chemistries, by adding a lithium-based system, it is hoping to support operators looking across both traditional lead-acid and newer energy storage architectures.
EnerSys says the DataSafe Noir system has been designed to reduce deployment complexity, improve reliability under real-world conditions, and give operators a clearer basis for decision-making when planning critical power systems.
“The industry has spent years optimising batteries – increasing energy density and reducing footprint,” said John Gagge, Vice President of Business Development, Energy Systems at EnerSys.
“But the real issue is how the system behaves under stress, particularly in high-density environments. The DataSafe Noir system is designed to give operators control over that – not just improve performance on paper.”
The system is backed by EnerSys’ installation, commissioning and service network, with the company positioning it for repeatable deployment across hyperscale and colocation environments. It’s also available immediately.
