Dragon Q Energy is proud to announce the conceptualization of a new product: the 0.25 MWh Data Center ESS. This concept represents an extension of our core subterranean battery technology into the data center market, where uptime, efficiency, and safety are critical—and real estate is always at a premium.

​

As demand for digital infrastructure continues to surge, data centers face a pressing challenge: how to expand capacity without increasing risk or consuming valuable surface area. Our conceptual system addresses this by being installed fully below ground, providing 0.25 MWh of storage per unit while freeing the surface for IT operations. Once buried, the system becomes naturally shielded from environmental exposure and human interference, making storage safer, more secure, and less obtrusive.

The concept adapts the same design principles that define Dragon Q Energy’s battery technology:

  • A hermetically sealed, Argon-filled environment where fire cannot occur.

  • Five on-board safety mechanisms to vent and contain thermal runaway events.

  • Passive geothermal cooling to reduce auxiliary energy demand and improve Power Usage Effectiveness (PUE).

  • Corrosion-resistant construction designed for durability in high-heat and high-humidity environments.

  • ​

Together, these features create the foundation for a storage system that is safe, efficient, and built for long service life with minimal maintenance requirements.

The 0.25 MWh Data Center ESS concept is also aligned with the modernization strategies of the world’s largest operators. By designing in line with META, Google, and the Open Compute Project’s 48VDC Rack & Power initiatives, the system ensures compatibility with the next generation of hyperscale infrastructure.

 

Value Propositions

  • Maximize Usable Space – Unlock 0.25 MWh of underground capacity per unit while keeping surface real estate available for critical IT equipment.

  • Ensure Operational Safety – Fire-proof, Argon-filled environment with five redundant safety mechanisms.

  • Optimize PUE – Passive geothermal cooling reduces energy overhead, lowers operating costs, and minimizes environmental footprint.

  • Align with Hyperscaler Standards – Developed in line with 48VDC Rack & Power initiatives to support modernization efforts.

​

While still in the conceptual stage, the 0.25 MWh Data Center ESS demonstrates how Dragon Q Energy’s subterranean architecture can be applied to one of the most demanding infrastructure sectors. It signals our vision for energy storage solutions that are safer, smarter, and more efficient—engineered from the ground down.
