Greenfield Hyperscale Holdings | A Sustainable Industrial Campus in West Texas

01 — Thesis

Manufacturing on-site power, and capturing everything it produces

Industry, utilities and data centers need reliable power on site, and the conventional routes to it are constrained. Grid connections take years, and gas turbine production is committed into 2031. Solid oxide fuel cells can be delivered in months and added one unit at a time, but supply is concentrated in very few manufacturers. GHH is developing megawatt-class units and the domestic manufacturing to build them.

A fuel cell converts fuel to electricity electrochemically, without combustion, and produces carbon dioxide, water and heat in fixed proportions. Because our units keep the fuel-side exhaust separate from the air, the carbon dioxide leaves nearly pure, ready for capture and permanent storage. The water and heat are recovered for use on site. We design for all four outputs from the start.

One unit, four outputs

Natural gas or biogas → Power Carbon dioxide Water Heat

Capturing a concentrated stream at the source needs drying and compression rather than chemical separation, so it is far smaller and less costly than removing the same carbon dioxide from the air later.

02 — Campus

A sustainable campus, built with its community

We are developing a sustainable industrial campus in the West Texas Permian Basin. A data center is its anchor tenant. The data center’s long-term revenue carries the shared costs that let the rest of the campus be built: fuel cell manufacturing, permanent carbon storage, water bottling, and the companies that locate beside them.

For our employees

A home on campus, not a man camp: one-, two- and three-bedroom homes, family units included.
Great meals included, made in part with vegetables and fish grown right on the campus.
Above-average wages for the region, with full benefits.
More than 1,500 jobs at full build.
A gym, rec hall, dining hall, pool, town green and a shop on site.

For our neighbors

Local taxes paid in full. We do not seek local tax abatements.
No NDAs with counties. Our agreements with local governments are public.
We will publish the campus’s water and power use.
Spare power for nearby communities through their utilities, below the rates those utilities charge.
About 1.3 million gallons a day of spare clean water.

For the environment

About 1.55 GW of our own fuel cells, so the campus adds no load to the local grid.
No combustion, almost no NOx or SOx, no diesel backup generators, and quiet operation.
Carbon dioxide captured on site and stored permanently deep underground.
No drinking water used. The fuel cells make about 2.3 million gallons of water a day, enough for the campus’s cooling.

For industry

Room to build beside us, with power, water and computing next door.
Shared services: homes, meals, maintenance and rail access.
Captured carbon dioxide and recovered heat for products made on the campus.

03 — Platforms

Our platforms

Different sectors, the same physics and the same ownership model: engineer around the constraint, secure the position, hold the asset.

Fuel Cell Manufacturing

USA

We are developing megawatt-class solid oxide fuel cells for round-the-clock power on site: a 1 MW unit and a 500 kW unit, each built into a 40 ft container and designed to work side by side in any mix. Today's leading solid oxide units are a few hundred kilowatts. Sites now need tens to hundreds of megawatts.

Megawatt-class

One unit does the work of three of today's leading units. Power is added one container at a time, in months rather than years.

Built in the United States

Our first units use proven stacks; everything around them is ours. Licensed stack manufacturing follows, on a US production line.

Capture-ready by design

The fuel-side exhaust is kept apart from the air, so the CO₂ leaves nearly pure, ready to capture instead of diluted in flue gas.

Carbon Capture & Permanent Storage

USA

We will capture CO₂ at the source, from our own fuel cells and from other people's operations, and store it permanently deep underground in West Texas.

From our own fuel cells

CO₂ is designed to leave our units about 97% pure, so capturing it will take drying, compression and liquefaction, not a separation plant.

From other people's operations

We will install, own and operate capture equipment at sites that make CO₂: farms and dairies, food plants, wastewater plants and landfills, plus industrial and data-center campuses. Where our fuel cells fit, the site will get power, heat and water too.

Permanent storage, open to other emitters

By pipeline, rail or truck to depleted gas reservoirs about 2.5 miles down, under the cap rock that held the gas for millions of years. We are developing our own Class VI storage under the Railroad Commission of Texas, and other emitters will be able to store with us.

Digital Infrastructure

USA · MENA

Off-grid data centers. We develop facilities that generate their own power and produce their own fresh water, operating in climates and markets where the conventional design fails — then partner with governments, operators and investors to build and own them.

Electrochemical generation

Fuel converts directly to electricity through an electrochemical reaction. No combustion, no turbine, no grid connection.

Modular compute

Factory-built and tested before it reaches site. Liquid cooling holds performance regardless of ambient temperature; capacity scales by adding modules, with no redesign.

Water as an output

Fresh water is produced as a direct byproduct of generation. No municipal connection, no desalination, no aquifer draw.

04 — Growth

Where we are growing

Each of our platforms produces inputs for the next. As the core businesses are established, we plan to build further companies on the same sites and the same outputs, each operated as its own business.

Planned

Distributed capture network

Fuel cell and capture units installed, owned and operated at farms, food plants, wastewater plants and landfills across the United States, with the captured carbon dioxide transported to permanent storage.

Planned

Industrial campus

A sustainable campus in the West Texas Permian Basin, anchored by a data center, providing shared power, water, heat, rail access and housing for our manufacturing and processing operations.

Planned

Water and beverage canning

Canning of still and sparkling water and beverages, using water recovered from our fuel cells and carbonation from our own carbon dioxide.

Planned

Controlled-environment agriculture

Indoor farming, developed with a partner, using power, water, heat and carbon dioxide from the campus to grow food year-round.

Planned

Aggregates and soil products

Construction aggregate made with captured carbon, and biochar soil products made from agricultural residues at our farm sites.

06 — Approach

How we develop projects

The pieces these projects need already exist: the emissions, the geology, the rights-of-way and proven equipment. They are rarely connected, and rarely owned by one party. We buy proven components from established suppliers, and design, build and own the systems around them.

Originate

We do our own process design, site selection and technology choices.

Structure

We arrange the capital, permits, offtake and partners, and hold each project in its own company so its risks stay separate.

Own & Operate

We invest alongside our partners and earn from the running asset, not from fees.

GHH runs on an AI operations layer that carries out financial modeling, regulatory and permitting research, engineering analysis and investor materials for a lean team. The same approach extends to the assets we are developing. Planned capabilities include AI-managed automated production lines, fleet monitoring and predictive maintenance across fuel cell units, automated measurement and reporting for stored carbon, and routing across the capture network.

07 — Stakeholders

Investors, partners and communities

GHH is a principal, not an advisor. We take ownership positions in what we build and stay in them — which means we carry the same exposure as the people who back us and the communities we build in.

Investors

Long-horizon and tax-advantaged capital taking principal exposure to first-of-a-kind infrastructure with policy-supported revenue — on the same side of the table as the founders.

Partners

Operators, technology and equipment providers, landowners and pipeline partners who bring a piece of the asset and share in what it earns.

Communities

Captured emissions, water recovered and reused on site, and skilled construction and permanent jobs — in regions where water access and air permits are live public issues.
