The two companies are already collaborating on a commercial pilot in Pohang, South Korea, where they plan to install a hydrogen-based ammonia distributed power system in 2026 and scale it up to 40MW by 2029.

GS Engineering and Construction led the funding round, which included participation from affiliated venture investors Xplor and GS Futures.

With the deal closed, GS E&C gains access to Amogy’s on-site ammonia-to-hydrogen technology, which can feed hydrogen into a fuel cell. The company aims to help engineer, build and scale the system globally.

“This investment goes beyond a simple financial participation – it represents a strategic collaboration to build a carbon-free ammonia energy ecosystem together with Amogy,” said GS E&C’s Jin-Hong Huh.

The Chief Data Officer added that the company could support GS E&C’s ESG goals too by “creating a sustainable society through carbon-free energy technologies.”

With this investment, Amogy said it has raised almost $100m throughout 2025, bringing the total raised since inception to $315m.

“Amogy has been extremely fortunate to partner with investors that are global leaders in the markets and industries that are core to our mission, and that’s exactly what GS E&C is,” explained Seonghoon Woo, co-founder and CEO at Amogy.

Speaking to H2 View earlier this year, an Amogy representative reiterated that its top priority this year is the completion and commissioning of its manufacturing and testing facility in Houston, which was delayed from its original start date in 2024.
