Carbon footprints bother environmentalists. The election of Donald Trump as the 47th President of the US also is a cause for worry for lovers of nature, as Trump is not enthusiastic about the protection of our environment.

However, there is a reason to rejoice today as Amogy, a provider of mature, scalable, and efficient ammonia-to-power solutions, has launched the world’s first carbon-free ammonia-powered maritime vessel. The vessel is named NH3 Kraken. The vessel has already completed its maiden voyage. The NH3 Kraken is a tugboat, originally constructed in 1957. It’s retrofitted with Amogy’s ammonia-to-electrical power system. The vessel sailed on a tributary of the Hudson River, upstream from New York City.

This is a significant demonstration towards reducing global carbon emissions. It’s also an important step nearer the goal of IMO (International Maritime Organization) of net-zero emissions by 2050. Amogy has proved both the viability of its technology and the potential of ammonia as a carbon-free maritime fuel.

CEO and Co-founder of Amogy, Seonghoon Woo, said, “Governments across the globe and industry organizations like the IMO have set aggressive goals to reduce global carbon emissions. These goals seem daunting, but they’re necessary and our successful demonstration of the world’s first carbon-free, ammonia-powered vessel proves that they’re achievable.”

Amogy has already demonstrated an aerial drone, commercial farm tractor, and semi-truck free of carbon. Liquid ammonia is split or “cracked” into its base elements of hydrogen and nitrogen by Amogy’s patented ammonia-to-electrical power system. Then the hydrogen is funneled into a fuel cell. The fuel cell generates high-performance power with zero carbon emissions. A sustainable, clean energy solution is offered by this technology. The solution is tailored for hard-to-abate sectors like maritime shipping, as well as stationary power generation applications.

Green ammonia, produced entirely with renewable energy, fuelled the NH3 Kraken, further reducing its carbon footprint. Close to 1 billion tons of greenhouse gases per year are emitted by global shipping. It’s equivalent to the emissions of a G7 country like Germany or Japan. The vast potential of ammonia’s value for transforming the shipping industry is validated by the successful voyage of the NH3 Kraken.

Woo added, “Ammonia is the world’s second most produced chemical, with around 20 million tons moving around the globe through 200 ports each year. With that track record, shifting the industry mindset to use it as a fuel is completely achievable, and can happen at an accelerated pace.”

With headquarters in Brooklyn, New York, Amogy has additional locations including Houston, Texas, Norway, and Singapore. In short, Amogy has launched the world’s first carbon-free ammonia-powered maritime vessel. It has already completed its maiden voyage. Amogy has demonstrated that a carbon-free ammonia-powered vessel can be a solution to carbon footprints.
