Dragon Q Energy is developing an exquisitely  safe, and efficient  battery energy storage system (BESS) for extreme climates. With our forward looking, patent pending pack housing, we are enabling a cell-to-BESS design that can readily integrate commercial lithium-ion (Li-ion) and Nickel Metal Hydride (NiMH) cells. Our packs utilize a modular, weld free design with direct liquid cooling and an inert atmosphere at the BESS level, affording enhanced safety, simplified assembly, and improved cycle life. This platform design strategy can seamlessly scale from 10 kWh residential systems  to 1 MWh systems for grid applications, and can be buried underground for efficient geothermal regulation, increasing energy resilience and security.

Harnessing Geothermal Cooling for BESS

It is well understood that the temperature just under the surface of the earth (3-4 meters) is significantly cooler and less prone to seasonal, diurnal and heatwave related temperature swings, even in tropical climates. This temperature consistency lends itself to being a thermal management solution for BESS when buried underground, and  is adaptive to climate change as more and more regions begin to experience extreme temperatures. DQE is conducting customer discovery in Southeast Asia, Middle East, and Central/South America. We have identified opportunities in large cities (load centers) where real estate for BESS projects is expensive, and the climate has been altered by global temperature increases.
