Questions to a Data Center Proponent in Montana

 Prompt:

I asked these questions to a proponent of data centers in Montana.

How do the closed-loop cooling systems in Montana work?

How is the off-grid power generated?

His answers are as follows.  Are they correct and what exceptions/loopholes did he omit?

“Closed loop works like your car. They fill the system one time with water and anti freeze the water is pumped through radiators and fans blow air through the radiator to cool the system. Once filled no new water is needed. After some years the system will be drained the liquids will get treated and recycled. Their water for initial filling is coming from an aquifer 3000 feet deeper than what the farmers are using and is totally separate from the farmers aquifer. The power is generated on site by using wind, solar and battery storage plus a natural gas generating plant. If for some reason they need to draw power from the grid the data center will pay premium prices to protect consumers. Most of the new proposed data centers are using closed loop cooling and self generated power unlike the data centers built years ago.”

Gemini Responds:
The proponent’s explanation is partially accurate on the basic physics, but it relies on significant oversimplifications, technical omissions, and legal/regulatory loopholes regarding water, grid impacts, and off-grid power generation.

Below is a breakdown of what is accurate versus the exceptions, edge cases, and omissions that were left out.

Part 1: Closed-Loop Cooling Systems

What He Got Right

• Basic Mechanics: High-density closed-loop systems do operate similarly to a car radiator (closed-loop direct-to-chip or chilled water circuit) using closed piping, glycol/anti-freeze additives, and air-cooled radiators (dry coolers).
• Initial Fill: Once charged with a treated fluid, the internal loop recirculates the same liquid without continuous intentional evaporation inside the loop.

What He Omitted & Exceptions

1. The "Peak Heat / Adiabatic" Loophole (Huge Water Spike in Summer):

• Omission: Air-cooled radiators lose efficiency when ambient summer temperatures rise (e.g., Montana high-plains heatwaves over 90°F–100°F). To prevent high-density AI chips from throttling, almost all modern "closed-loop" data centers deploy adiabatic or hybrid booster units.
• The reality: When it gets hot, these systems spray mist/water onto the outdoor radiator coils to lower the air temperature via evaporation. While advertised as "closed loop," they can still consume thousands to tens of thousands of gallons of water per day during hot periods.

2. System Maintenance, Flushing, and Leaks:

• Omission: Closed systems require routine maintenance, mineral flushing, chemical biocides, and periodic blowdown/draining to prevent corrosion and fouling. They are not indefinitely maintenance-free "fill once and forget" systems.

3. Disposal of Industrial Fluids:

• Omission: Draining water mixed with glycol, scale inhibitors, and anti-corrosive chemicals requires hazardous wastewater treatment. Disposing of thousands of gallons of chemically treated industrial coolant in rural Montana—where municipal wastewater infrastructure is limited or non-existent—presents a major localized waste management challenge.

Part 2: The Deep Aquifer Claim (e.g., Madison Aquifer)

What He Got Right

• Developers in Montana (such as proposed facilities in Yellowstone County/Broadview) have planned to drill deep wells into deep bedrock layers like the Madison Group Aquifer (4,000–5,000 feet down) to avoid shallow domestic/agricultural wells (like the Eagle Aquifer).

What He Omitted & Exceptions

1. Hydrologic Interconnection & Long-Term Depletion:

• Omission: Deep aquifers are rarely 100% hydrologically isolated over long periods. Fractures, fault lines, or unsealed legacy oil/gas boreholes across Montana can create cross-contamination paths or inter-aquifer leakage when massive continuous pumping shifts pressure gradients.

2. Water Quality & Treatment Waste:

• Omission: Water pulled from 3,000 to 5,000 feet deep is often brackish, mineral-heavy, or high in total dissolved solids (TDS). To use it in sensitive data center chillers, it must undergo Reverse Osmosis (RO) filtration.
• The reality: RO filtration produces a heavy waste stream ("brine reject"). For every 10 gallons of deep aquifer water purified, 2 to 4 gallons are discarded as salty, mineralized wastewater that must be disposed of.

3. Montana Water Rights Exemptions:

• Omission: Industrial projects frequently leverage exempt well statutes or water transfer loopholes to bypass Montana’s closed-basin rules and DNRC (Department of Natural Resources and Conservation) public review processes designed to protect local watersheds.

Part 3: Off-Grid Power & Grid Reliance

What He Got Right

• Hybrid Designs: Many proposed rural data centers incorporate on-site solar, wind, battery energy storage systems (BESS), and natural gas turbines to secure high power capacities.

What He Omitted & Exceptions

1. "On-Site Natural Gas" is the Dominant Baseload:

• Omission: Wind and solar are non-dispatchable (variable) intermittent sources. High-density AI workloads require 99.999% uptime at a flat, massive load (e.g., 50 MW to 500+ MW continuously).
• The reality: The "natural gas plant" is not just a backup; it becomes the primary baseload engine running 24/7. This introduces continuous localized carbon emissions, air quality permitting issues, and pipeline infrastructure demands.

2. The "Premium Price" Grid Drawing Myth:

• Omission: Paying a premium price on the spot market does not automatically protect local rate-payers or grid stability.
• The reality:

• Transmission Bottlenecks: When a data center draws massive power during localized heatwaves or cold snaps, it strains physical transmission lines and transformers regardless of what rate it pays.
• Resource Adequacy & Capacity Cost: If power utilities (like NorthWestern Energy) have to procure extra generation capacity or build new transmission lines to support grid connections for data centers, those long-term capital costs are often spread across all rate-payers over time through utility rate base increases.

Key Summary of Omissions

Topic	What Was Claimed	What Was Omitted
Cooling	Zero new water needed after initial fill.	Hot summer days trigger adiabatic evaporative cooling, causing temporary spikes in water usage.
Water Source	Deep aquifers are 100% separate and safe.	Deep water requires heavy Reverse Osmosis purification, generating large toxic brine reject waste streams.
Chemical Disposal	Fluids are just recycled after years.	Requires specialized industrial disposal for glycol/additive waste in rural areas with limited wastewater infrastructure.
Power	Powered by renewables + gas backup.	Wind/solar cannot support 24/7 continuous baseloads; the natural gas plant acts as the primary power source.
Grid Impact	Paying premium prices protects consumers.	Physical line congestion and long-term utility infrastructure upgrades can drive up rates for everyday consumers.

Energy Self-Sufficiency by State in the USA

 Energy Self-Sufficiency by State

Energy self-sufficiency is measured using data from the U.S. Energy Information Administration (EIA) by comparing a state's total primary energy production to its total primary energy consumption across all sectors (electricity, heating, industrial, and transportation).

States with a production-to-consumption ratio above 100% generate an energy surplus (net exporters), while those below 100% experience an energy deficit and rely on interstate transmission, pipelines, or imports (net importers).

Net Exporters (Self-Sufficient States)

These states produce significantly more primary energy (coal, natural gas, crude oil, nuclear, and renewables) than they consume.

1. Wyoming: Exceeds 1,000% self-sufficiency; the nation's leading coal producer, alongside large natural gas and wind output.
2. West Virginia: Produces ~400–500% of its needs, largely driven by coal mining and Marcellus shale natural gas.
3. North Dakota: Produces ~400–500% of its needs, propelled by Bakken formation oil and natural gas production.
4. New Mexico: Produces ~350–400% of its consumption due to high crude oil production in the Permian Basin.
5. Pennsylvania: Produces ~250–300% of its needs, driven by heavy natural gas extraction and nuclear power exports.
6. Texas: Produces ~200–250% of its needs; the country's single largest total energy producer (oil, gas, and renewables) despite heavy industrial consumption.
7. Alaska: Produces ~200% of its needs, supported by North Slope crude oil extraction.
8. Oklahoma: Produces ~180–200% of its needs through natural gas, crude oil, and wind generation.
9. Iowa: Produces ~150–170% of its needs, largely via biofuels (ethanol/biodiesel) and extensive wind capacity.
10. Colorado: Produces ~140–160% of its needs from natural gas, crude oil, and growing renewable capacity.
11. Louisiana: Produces ~130–150% of its needs through natural gas and refining, though offset by massive industrial demand.
12. Utah: Produces ~120–140% of its needs via natural gas, coal, and solar energy.
13. Montana: Produces ~120–130% of its needs through coal, hydro, and wind generation.
14. Nebraska: Produces ~110–120% of its needs, supported by corn ethanol biofuel production and wind generation.
15. Alabama: Produces ~105–115% of its needs through nuclear, natural gas, hydro, and biomass.
16. Kansas: Produces ~100–115% of its needs, driven by heavy wind energy expansion and oil/gas production.
