Data storage facilities could potentially popularize diverse energy storage options, claim developers.
The data center industry is focused on solutions that strike a balance between speed to market, operational reliability, and sustainability. This shift is driven by two primary trends: the rapid growth of AI-driven data processing and a strong emphasis on sustainability and resilient power solutions.
Advanced AI applications significantly increase data generation and compute loads, pushing data centers to expand storage and power infrastructure. This growth fuels the need for energy storage to handle the 24/7, high-capacity operations efficiently, while supporting performance and scalability requirements.
Data centers are under pressure to meet ambitious sustainability targets by reducing power consumption and carbon footprint. This drives adoption of energy-efficient storage technologies for data, such as newer HDDs and SSDs with lower power per terabyte, and flexible power solutions including renewable energy and batteries to reduce reliance on fossil fuels and grid power.
Many data centers incorporate battery-based systems or novel technologies like organic flow batteries to improve resilience and reduce emissions. These storage systems enable rapid power up, peak load management, and backup power without the environmental downsides of traditional diesel generators. Such deployments are expanding, with pilot projects underway for new battery types capable of multi-hour discharge at megawatt scales.
With data centers accounting for over 4% of U.S. electricity use in 2023 (potentially rising to 12% by 2028 due to AI), energy storage helps smooth grid demand and allows data centers to better manage power costs and reliability amid growing grid constraints.
Notable developments include Prometheus Hyperscale's consideration of purchasing up to two 12.5 MW purchases of XL Batteries' organic flow batteries, one each in 2028 and 2029, pending the pilot. Eos Energy Enterprises, a company producing zinc-based batteries, has also entered talks with an unnamed, large-scale developer of data centers.
However, it's important to note that many of the energy storage options currently of interest to data centers remain relatively unproven in the real world. There is a natural tension among data center operators who want to wait and see how pilot-scale projects pan out before deploying an unproven technology at scale, but doing so could result in missing out on opportunities.
Battery chemistry decisions for energy storage are increasingly use-case driven. For instance, nickel-zinc batteries are attracting attention due to their high power density, improved safety profile, and environmental benefits, while supercapacitors could prove interesting due to their ability to provide a very large amount of power for a short period of time.
In conclusion, the adoption of energy storage technologies in data centers is propelled by the need for high power reliability and rapid scalability to support AI and data growth, alongside strategic goals to improve sustainability and grid resilience. Novel battery technologies and onsite renewables are playing growing roles in this transformation. However, the industry must navigate the challenges of adopting unproven technologies while ensuring reliability and cost-effectiveness.
