Less Cooling Power.
More Compute.
Data center growth is power constrained. Cooling uses too much power.
The rush for power has overshadowed how power is actually used. Conventional cooling solutions are energy intensive. Existing power solutions – nuclear, gas, grid interconnections – are slowing down growth. Cooling is the largest non-IT load. Brightcore’s next-generation geothermal cooling solution materially reduces
the power needed for cooling; unlocking significantly more power for compute.
More servers, more tokens, more value — without more energy.
Reduce power with geothermal cooling.
Stop relying on outdoor air for heat rejection when conventional equipment is least efficient. Geothermal rejects heat to naturally cool ground using only pumps and underground piping, while dry coolers and chillers run when they’re most efficient.
This isn’t traditional geothermal.
Active optimization makes Brightcore’s system 2–3x smaller than traditional geothermal. It picks the most efficient cooling at the right time and uses spare dry cooler capacity on cool days to recharge the borefield faster. The result: geothermal for any geography, site and scale.
- Up to 85% cooling power reduction*
- Cooling drops from 25%-45% to 4%-6% of total site power*
- Peak PUE 1.09 or lower*
- High temperature liquid cooled compute versus conventional chiller-based cooling
- *Two ways to use the power savings
- Add more compute without adding more power
- 10%-20% more compute
- $4.1B NPV**
- Lower your energy spend
- 10%-20% less site energy
- $1.1B NPV**
- In most cases, geothermal costs the same or less as conventional solutions by reducing the equipment required.
- Noise: reduce or eliminate chillers, downsize the number of dry coolers required
- Space: reduce the amount of above ground conventional cooling equipment; systems can be built under parking lots, below above- ground equipment and buildings
- Water: 0 WUE, eliminate water consumption for cooling
- Reliability: The combined solution serves 100% of the cooling demand 24/7/365
- Lower maintenance: fewer moving parts and no major equipment replacements
One integrated product.
- System design & construction
-
- 2-3x smaller borefield versus traditional geothermal designs
- Quality construction executed or managed by Brightcore
-
- System design & construction
- Real-time control optimization integrated with building management systems (BMS/BAS)
- Long-term thermal management of the geothermal borefield maintains peak performance
Deployed in months.
- A 250MW data center geothermal borefield can be installed in 6 months
- Modular borefield design means installation happens in phases so cooling comes online as it gets built, minimizing speed to first token
Scalable to all data centers.
From small megawatt self-hosted sites, up to giga-scale AI factories
- Next-gen AI / HPC: Highest efficiency, chiller-free design ideal for high-temperature compute
- Retrofit: Phase in geothermal, then downsize or retire chillers
- Legacy upgrade: Add geothermal to cut energy spend and extend existing equipment life
*Performance and savings represent a geothermal solution combined with dry coolers and no chiller-based cooling. Geothermal and dry coolers provide 100% of the data center cooling load including high temperature liquid cooled compute and medium temperature air cooled whitespace. Savings are compared to conventional chiller-based cooling.
