Green Ammonia





The Green Ammonia Project Planned in Adak, AK

1. Introduction

As the global economy seeks alternatives to fossil fuels, green ammonia—a carbon-free energy carrier—has garnered increasing interest as a clean fuel for power generation, shipping, and industrial use. In May 2025, The Aleut Corporation and Pacific H2 announced a partnership to develop a major green ammonia facility on Adak Island, Alaska. This initiative represents a pioneering effort to harness renewable wind power in one of the most strategic locations in the United States for export to Asian markets ammoniaenergy.org+9akbizmag.com+9pacifich2.com+9.


2. Site Selection & Strategic Location

Geographic Advantages

Adak Island lies at the eastern end of the Aleutian chain, where the Bering Sea meets the North Pacific. It holds the distinction of being the westernmost ice-free deepwater port in the United Statesaleutcorp.com+2akbizmag.com+2ammoniaenergy.org+2That unique positioning makes it exceptionally well-placed to ship to Asia—7 days to Tokyo and 8 to Busan—offering shorter routes compared to Gulf or Australian facilitiespacifich2.com+1h2carrier.com+1.

Existing Infrastructure

The island’s history as a U.S. Navy base until 1998 leaves behind valuable infrastructure: a port, runways, roads, fuel storage, housing, and power systems—all of which can be repurposed for green ammonia productionqcintel.com+8pacifich2.com+8ammoniaenergy.org+8.


3. Project Partners & Roles

The Aleut Corporation

An Alaska Native regional corporation under the Alaska Native Claims Settlement Act, Aleut owns approximately 3,500 acres on Adak Island and serves over 5,000 Unangax̂ shareholdersammoniaenergy.org+4aleutcorp.com+4akbizmag.com+4It is leading project permitting, land leasing, and regional coordination.

Pacific H2

Based in Oregon, Pacific H2 will develop and operate the green ammonia facility, leveraging its expertise in low-carbon hydrogen and ammonia technologies m.facebook.com+9aleutcorp.com+9pacifich2.com+9.

H2Carrier

Working with Pacific H2, H2Carrier will deploy its P2XFloater™ vessel—a floating production, storage, and offloading (FPSO) platform—that will house electrolysers and Haber–Bosch units to produce ammoniapacifich2.com+2h2carrier.com+2ammoniaenergy.org+2.


4. Technical Overview

Power Source & Electrolysis

Onshore wind turbines will provide the renewable electricity necessary to power electrolyzers, splitting water into hydrogen and oxygen qcintel.com+2akbizmag.com+2pacifich2.com+2.

Ammonia Synthesis

The produced hydrogen is combined with atmospheric nitrogen via the traditional Haber–Bosch process to synthesize ammonia.

Floating Platform Advantage

The P2XFloater FPSO—a vessel approved by classification society DNV—will contain all ammonia production, storage, and offloading facilities directly at Pier 3. Floating infrastructure reduces capital costs, can be relocated if necessary, and allows reuse after the facility’s operational life linkedin.com+8ammoniaenergy.org+8pacifich2.com+8.


5. Production Scale & Timeline

The facility aims to produce roughly 200,000 metric tonnes per year of green ammonia. This volume aligns with initial capacity targets for export facebook.com+6h2carrier.com+6qcintel.com+6Estimated timelines include:

Monthly shipments to international customers are expected once operations begin akbizmag.com+1aleutcorp.com+1.


6. Economic & Community Impacts

Job Creation & Local Benefits

During operations, the project is expected to directly support about 150 jobs. It may also involve rotational staffing, housing refurbishment, and investments in local services such as health clinics, recreation centers, emergency response, greenhouses, and clean heating systems linkedin.com+3akbizmag.com+3aleutcorp.com+3.

Broad Regional Effects

Through infrastructure upgrades, Aleut aims to spur sustained economic development in the region. Coastal and port rejuvenation could attract further investment, and partnership with SpinLaunch suggests potential for additional high-tech ventures ammoniaenergy.org+4akbizmag.com+4aleutcorp.com+4.

Economic Investment

Public communications suggest this is a multi-billion-dollar initiative. One report cites a land-lease-based project value of approximately $1.7 billion facebook.com.


7. Logistics & Market Access

Export Markets

Adak’s shipping advantage extends to major energy consumers in Asia. Shortened sailing routes reduce costs and timeline, with comparison metrics showing Adak shipments to Tokyo being significantly faster than from Australia or Gulf ports ammoniaenergy.org+6pacifich2.com+6h2carrier.com+6Additionally, the facility enables export via barge to West Coast U.S. ports and the potential for ammonia bunkering at Adak pacifich2.com.


8. Environmental Significance

Green ammonia contains no fossil carbon, supporting carbon-neutral or even carbon-negative strategies if paired with sustainable power. It can replace coal or natural gas in power plants, industrial processes, or marine fuel supplying zero-emission alternatives .

Using onshore wind on renewable offshore-adjacent sites like Adak, combined with floating production, reduces carbon footprint and simplifies decommissioning compared to land-based facilities .


9. Challenges & Considerations

Wind Resource & Technology

Successful operation depends on the quality of the wind resource. Meteorological data acquired in summer 2025 will inform turbine selection; delays in permitting could shift timelines .

Regulatory & Permitting

Federal, state, and environmental approvals are required. Early stages have begun, but coordination across agencies remains essential ammoniaenergy.org.

Technical Integration

Operating a large floating electrolysis and synthesis plant in a remote, harsh weather environment presents both engineering and maintenance challenges.

Market & Price Risks

Global ammonia markets—particularly low-carbon ammonia—are still developing. Long-term purchase agreements are essential to secure revenue streams and underpin project financings.


10. Conclusion

The Adak green ammonia project—a partnership between Aleut Corporation, Pacific H2, and H2Carrier—aims to establish a scalable, renewable fuel export hub strategically positioned for fast access to Asian markets. Featuring a floating FPSO platform powered by wind, it navigates construction advantages and modularity while promoting sustainable infrastructure and employment in a historically significant yet remote community.

If successful, it could position Alaska—and especially the Aleutians—as a central player in the clean energy transition. With production sets to begin by 2031, the project represents a concrete step toward a global low-carbon fuel economy.
