Pacific H2 has entered a partnership to lease about 3,500 acres of land located on Adak Island from the Aleut Corporation, one of thirteen native regional corporations in Alaska. The land will be used for onshore wind energy development, and the generated energy will feed into the production of renewable ammonia. At this site, Pacific H2 plans to produce about 200,000 tons per year of renewable ammonia for export.

For ammonia production, the project will deploy the P2XFloaterTM, a floating production, storage and offloading (FPSO) vessel developed by H2Carrier. The vessel, which received Approval in Principle (AiP) from DNV, is designed to house on-deck PEM electrolysers for hydrogen production and Haber Bosch equipment for ammonia production. Compared to shore production, the FPSO method has lower construction costs, and the vessel can be relocated to match demand or resource availability.

As a next step for the project, meteorological monitoring stations will be installed on Adak to generate wind data and determine the best suited turbine models to be deployed. The construction phase will take an estimated three years, with ammonia production and export set to commence by 2031. Permitting and early stage development is currently underway.

Adak Island, which was a US military base until 1998, sits near the meeting point of the Bering Sea and North Pacific Ocean. It is the USA’s westernmost. ice-free deepwater port which is situated within a shipping distance of 7 days to Japan and 8 days to South Korea, two countries that are expected to be major offtakers of low carbon ammonia. Adak also has already existing infrastructure, including power grids, roads, a dock and fuel storage, which can be repurposed to support the envisioned ammonia project.

The project is also expected to positively impact the local community through employment of people (about 150 during operations), housing development for workers, improved local services such as healthcare, recreation centre, emergency response and sustainable infrastructure such as greenhouses and clean heating.

This is a meaningful opportunity for Adak, for Alaska, and for the renewable energy industry. Pacific H2’s project brings global innovation to a local setting. Most importantly, it opens the door for sustainable economic growth in Adak and creates long-term opportunities for the region.
