Integrated infrastructure for the AI economy
Independent advisory today. Innovating system-level solutions for tomorrow.
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.
ArNeil Advisory · available today
Integrated infrastructure advisory before capital commits.
ArNeil helps owners, developers, investors, and technology partners evaluate the interactions among power, thermal systems, water, storage, carbon, controls, permitting, and project economics. Engagements are founder-led, fixed-scope, and designed to complement—not replace—the owner’s engineering team, EPC, utility, legal counsel, or financial advisers.
Infrastructure Strategy
Direction-setting for greenfield campuses, site selection, infrastructure master planning, technology posture, and build-versus-buy choices.
Typical output: infrastructure roadmap, technology strategy, executive recommendation, and risk framework.
Developers · Owners · Investors
Technical Due Diligence
Independent validation of proposed sites, technologies, vendor claims, and project assumptions before investment, acquisition, joint venture, or major commercial commitment.
Typical output: technical opinion, assumption challenge, interface-risk review, and investment-committee findings.
Investors · Lenders · Acquirers
Integrated Architecture Review Flagship
Evaluation of how power, cooling, water, storage, carbon, controls, economics, and permitting function as one connected system—not simply whether each discipline works in isolation.
Typical output: architecture scorecard, interface-risk assessment, alternative concepts, and prioritized optimization opportunities.
Developers · Owners · EPC interface
Innovation Architecture
Development of alternative system concepts when conventional approaches do not deliver the required technical, resilience, environmental, or commercial outcome. Recommendations draw on decades of industrial systems integration and technology-development experience.
Typical output: concept alternatives, technology screening, novel architecture options, development pathway, and commercialization considerations.

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.

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.
ArNeil Labs · technology-development agenda
Developing new system-level concepts where recurring constraints justify it.
ArNeil Labs is the founder-led development track for selected infrastructure concepts at the research, provisional-patent, and early-engineering stages. Its purpose is to translate recurring industry constraints into independent methods, protected system concepts, engineering models, and future software tools.
Not every engagement requires new technology. When recurring constraints cannot be solved adequately through conventional engineering, ArNeil may develop an independent system concept, protected method, engineering model, or future software tool.
ArNeil owns three U.S. provisional patent applications filed in 2026. These concepts remain under development and are not yet commercially available.

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.

About the founder
Sanjay Dube, PMP
Sanjay Dube’s career has been defined by integrating systems that organizations often manage separately. Across industrial refrigeration, onsite energy, carbon capture, battery technology, water systems, advanced controls, process modeling, and digital twins, he has built architectures designed to improve both technical performance and commercial outcomes.
ArNeil applies that systems-engineering perspective to the infrastructure decisions now shaping the AI economy.
