Is hydrogen the energy savior everyone claims, or just a really expensive distraction? The breathless coverage of a “hydrogen economy” often glosses over a fundamental problem: hydrogen is a pain to move and store. The real story here isn't hydrogen itself – it's ammonia, and the companies quietly building the infrastructure to deliver hydrogen as ammonia. While Silicon Valley chases flashy direct air capture schemes, a Brooklyn-based firm, Amogy, is demonstrating a surprisingly practical solution that leverages decades-old global infrastructure.
For years, the power sector has been grappling with the challenge of decarbonization. Burning fossil fuels is out, renewables are intermittent, and batteries aren’t yet scalable enough to reliably power entire grids. Hydrogen has been touted as the answer, a clean fuel that produces only water as a byproduct. But transporting hydrogen – a gas that requires either extreme compression or supercooling – is incredibly expensive and energy-intensive. That’s where ammonia comes in. Ammonia (NH3) is a liquid at room temperature, boasts a high energy density, and, crucially, the world already has a massive system for producing, shipping, and storing it, primarily for agricultural fertilizer. The cost of transporting ammonia is roughly one-fifth that of transporting liquid hydrogen, a difference that could make or break the economics of a clean energy transition.
Amogy isn’t just theorizing about this. They’ve built a technology to “crack” ammonia – splitting it back into its constituent nitrogen and hydrogen – and then use that hydrogen in fuel cells or hydrogen engines. This isn’t some lab experiment; in 2023, they powered the world’s first clean ammonia-powered vessel, the NH3 Kraken, a retrofitted 1957 tugboat, on the Hudson River. Seonghoon Woo, Amogy’s CEO, frames it plainly: “Hydrogen will play an important role in a diversified strategy because it’s less expensive and more reliable than clean alternatives like solar and wind.” He’s not dismissing renewables, but acknowledging the practical realities of grid-scale power. The infrastructure for hydrogen is still nascent, but ammonia’s is robust, a fact often overlooked in the rush to embrace the latest tech.

The implications extend far beyond tugboats. Amogy is currently preparing a 1-MW pilot project in Pohang, South Korea, with plans to scale to 40 MW by 2029, in partnership with GS Engineering & Construction (GS E&C) and HD Hyundai Infracore (HDI). This isn’t just about deploying technology; it’s about building a regional hub for clean energy innovation. South Korea, like many countries in the Asia-Pacific region, is heavily reliant on fuel imports. Ammonia offers a way to leverage existing infrastructure and reduce dependence on volatile global energy markets. Jong-hwan Lee, senior vice president at GS E&C, put it succinctly: “ammonia/hydrogen is the key to energy transition success from carbon-based energy.” This isn’t altruism; it’s strategic energy independence.
But Amogy isn’t alone in recognizing ammonia’s potential. Major players like Air Liquide, thyssenkrupp Uhde, and Mitsubishi Heavy Industries are also investing heavily in ammonia cracking technology. Air Liquide recently launched a 30-tons-per-day pilot unit in Belgium, and completed the acquisition of DIG Airgas in South Korea, bolstering their hydrogen infrastructure. Even JERA, Japan’s largest power generator, is planning to shift entirely to ammonia by the 2040s, backed by a $4 billion facility in Louisiana, the Blue Point project, a joint venture with CF Industries and Mitsui. The Japanese government is so committed, they’re offering subsidies to offset the cost difference between ammonia and coal for 15 years. This isn’t a fringe movement; it’s a fundamental shift in how major energy players are approaching decarbonization.
The current hype cycle focuses on direct hydrogen production, often through electrolysis powered by renewables. While important, this approach ignores the logistical nightmare of distribution. Ammonia sidesteps that problem, utilizing a global network already in place. The challenge now isn’t proving the technology – Amogy has already done that – it’s scaling it. The efficiency of ammonia cracking, the cost of catalysts, and the integration with existing power infrastructure are all critical factors. But the momentum is undeniable, with projects underway in South Korea, Taiwan (through a partnership with GreenHarvest), and Singapore (with A*STAR).
Here’s what to watch for: by late 2026, keep an eye on the pilot system Amogy and GreenHarvest are installing at a large industrial facility in Taiwan. If that deployment proves successful, and demonstrates a clear economic advantage over traditional energy sources, we’ll see a cascade of similar projects across the island’s high-tech manufacturing sector – and beyond. The question isn’t if ammonia will play a role in the future energy landscape, but how quickly it will become the dominant carrier for a truly global hydrogen economy.
