Legacy chemistries under growing pressure
For decades, lead‐acid batteries served as the standard solution for data‐centre backup power. Their long operating history, relatively low upfront cost and straightforward global transport made them a practical choice for early digital infrastructure. However, evolving environmental regulations are making this legacy chemistry increasingly difficult to justify. Policies such as the Waste Framework Directive and REACH regulations continue to tighten controls around hazardous materials, including lead. In addition, lead‐acid systems require large physical footprints, frequent maintenance and periodic replacement cycles that increase both operational disruption and lifecycle emissions. These factors ultimately raise the total cost of ownership while complicating environmental compliance.
Lithium-Ion batteries emerged as the modern alternative, largely due to their high energy density and longer lifespan compared with lead-acid systems. While Lithium-Ion technology has seen widespread adoption in consumer electronics and energy storage applications, considerations around safety and sustainability remain important in mission-critical environments. Thermal runaway events associated with Lithium-Ion systems have prompted increased industry focus on safety standards, system design and facility-level mitigation strategies. In addition, lithium extraction and processing present environmental challenges, while large-scale recycling infrastructure for Lithium-Ion batteries remains limited. As operators prepare to disclose lifecycle impacts under EU Battery Regulation( 2023 / 1542) and manage Scope 3 emissions reporting requirements, the broader environmental footprint of Lithium-Ion systems is becoming increasingly visible.
Nickel‐zinc: A circular and responsible alternative
Against this backdrop, nickel‐zinc( NiZn) technology has emerged as a compelling alternative for modern UPS applications. NiZn batteries combine high power performance with strong sustainability credentials, aligning closely with Europe’ s evolving regulatory priorities.
ZincFive’ s nickel‐zinc chemistry relies on abundant and widely available materials that are significantly more common in the earth’ s crust than lithium or lead. The batteries are composed of non‐toxic

materials and are more than 90 % recyclable, supporting circular‐economy objectives that are central to EU environmental policy. Lifecycle analysis shows that NiZn systems produce 25 %– 50 % lower greenhouse‐gas emissions than comparable lead‐acid or Lithium‐Ion technologies, as validated by third-party analysis.
Water consumption is also dramatically reduced. From raw material extraction through end‐of‐life processing, nickel‐zinc batteries require approximately 96 % less water than Lithium‐Ion systems. Combined with an
