Integrated infrastructure for the AI economy
Independent advisory for today’s capital decisions. System-level innovation for tomorrow’s infrastructure challenges.
How we think
Industrial infrastructure has traditionally been engineered one discipline at a time.
The AI economy requires engineering it as one system.
The AI economy requires engineering it as one system.
01
Find the seams
The largest risks often sit between disciplines, vendors, and commercial assumptions.
02
Model the whole system
Technical performance, resilience, schedule, capital, and operating economics must be evaluated together.
03
Stay independent
ArNeil does not sell equipment, construction, power, or financing. Recommendations are guided by technical merit, commercial viability, and the owner's objectives.
Integrated infrastructure architecture
One decision framework across six interdependent systems.
ArNeil evaluates how infrastructure choices interact—not merely whether each subsystem works in isolation—especially during site selection, investment approval, pre-FEED development, and major vendor commitment.
01
Power
Grid supply, onsite generation, fuel, interconnection, and operating strategy.
02
Thermal
Heat rejection, refrigeration, liquid cooling, heat recovery, and efficiency.
03
Water
Source, treatment, reuse, discharge, and water-constrained operation.
04
Storage
Battery, UPS, thermal storage, microgrids, and resilience posture.
05
Carbon
Emissions, carbon-capture readiness, incentives, and value pathways.
06
Controls + Economics
Simulation, digital twins, operational logic, commercial tradeoffs, and risk.
Integrated architectureA coherent, financeable infrastructure strategy with fewer hidden interface risks and clearer capital decisions.
Services
Two ways ArNeil creates value.
Independent advisory for today’s infrastructure decisions. System-level innovation for tomorrow’s challenges.
How ArNeil creates value
Confirm what works. Challenge what does not. Create a better architecture when justified.
The work begins with the customer’s proposed solution and progresses only as far as the project requires.
01
Customer challenge
Define the decision, project constraints, and consequences of getting it wrong.
02
Integrated systems review
Evaluate power, thermal, water, carbon, controls, permitting, and economics together.
03
Hidden constraints
Identify fragile assumptions, interface risks, and dependencies between disciplines.
04
Optimize the proposal
Confirm the architecture where it is sound and recommend focused improvements where needed.
05
Develop novel concepts
When conventional options fall short, create alternative system architectures for the customer’s specific project.
Who we work with
Independent support for organizations making high-consequence infrastructure decisions.
Data-center developers
Site selection, pre-FEED decisions, architecture optimization, and vendor challenge.
Infrastructure investors
Technical diligence, downside risk, commercial assumptions, and capital-decision support.
Utilities and power developers
Grid, onsite generation, fuel, storage, resilience, and campus integration strategy.
EPC and technology partners
Independent cross-disciplinary review and development of differentiated concepts.
Private-equity firms
Independent validation of infrastructure platforms, acquisitions, and growth investments.
Industrial site owners
Assessment of brownfield assets and sites being repositioned for AI infrastructure.
Cooling and water OEMs
System-level application strategy beyond individual equipment performance.
LNG and energy asset owners
Evaluation of cold-energy, onsite power, carbon, and co-location opportunities.
Typical engagements
Focused work around a specific capital decision.
01
Independent review of a proposed AI campus before FEED, including power, cooling, water, carbon, controls, and interface risks.
02
Technical diligence for an investor evaluating the credibility, economics, resilience, and schedule of a hyperscale infrastructure proposal.
03
Evaluation of LNG cold-energy recovery, onsite generation, and thermal integration for compute infrastructure.
04
Water strategy for a water-constrained or Zero Liquid Discharge campus, including reuse, treatment, and discharge architecture.
05
Independent confirmation of a proposed architecture—or development of alternative concepts when the current design leaves material value or resilience unrealized.
Why independent
The recommendation is the product.
ArNeil does not manufacture equipment, construct facilities, sell utilities, provide financing, or represent technology vendors. Recommendations are based on technical merit, commercial viability, project risk, and the owner’s objectives.
ArNeil complements — and does not replace — your engineering team, EPC contractor, utility, or equipment specialists. We provide an independent perspective before major commitments; formal design, FEED, permitting, and procurement remain with your project team.
No equipment agenda. Technologies are evaluated on system value, not channel economics.
No construction interest. ArNeil can challenge cost, scope, and complexity without protecting downstream revenue.
No discipline boundary. The review follows the risk across power, cooling, water, carbon, controls, permitting, and economics.
No requirement to invent. A sound proposed architecture can be confirmed; novel design is pursued only where it creates material value.
Innovation heritage
Industrial innovation that informs a new generation of infrastructure technology.
25+Years across chemicals, power, thermal, water, carbon, and digital engineering
$1B+Total value of a DOE-funded carbon-capture program; founder served as technical lead*
$50M/yrIndustrial decarbonization monetized into an annual business; 45Q-fluent
200 MWOnsite generation operated within a $300M industrial energy portfolio
From industrial innovation to AI infrastructure
Throughout his career, founder Sanjay Dube has translated complex engineering problems into industrial technologies across thermal systems, water treatment, electrochemical processes, batteries, process engineering, and controls.
That experience includes serving as technical lead on DOE-funded, commercial-scale carbon-capture development; designing a first-of-a-kind zero-liquid-discharge water architecture for an 800 MW power plant; and monetizing industrial decarbonization into a $50M/year business. ArNeil does not claim ownership of those earlier inventions or of any prior-employer program. The company applies the founder's systems-engineering experience to develop new, independent technology—the focus of ArNeil Labs—for AI infrastructure.
