AmmPower brings clean energy to the world through the power of green ammonia, a natural chemical with 1.8 times the energy density of hydrogen.

Ammonia (NH3) is a colorless chemical, but is often referred to as “green”, “blue” or “gray”. When ammonia is formed, hydrogen and nitrogen atoms combine to form the ammonia product, NH3. The color prefix refers to the energy source used to power the process, determines how hydrogen is produced, and represents the impact of all associated emissions.

The traditional process of gray ammonia synthesis uses fossil fuels, mainly natural gas, as a feedstock to generate hydrogen by steam reforming – a carbon process in which the question of associated upstream carbon emissions remains, even if the ammonia reaction itself does not generate emissions. Blue ammonia is a similar process, but carbon-related emissions are captured and stored or used elsewhere. In fact, 98% of ammonia plants around the world use fossil fuels as a feedstock for hydrogen production for the ammonia synthesis process, according to the US Energy Information Administration (EIA).1

However, green ammonia uses green hydrogen and green energy to power the synthesis process. For hydrogen to be green, it must be produced without the use of fossil fuels or the production of carbon-containing greenhouse gases. The most common method for obtaining pure hydrogen is by electrolysis of water (H2O), which, simply put, is to send an electric current through water, thus “electrolyzing” it to separate the hydrogen and oxygen atoms.

Impact of ammonia

Ammonia is the second most widely used inorganic chemical in the world. In 2020, 176 million tonnes of ammonia were produced, resulting in approximately 500 million tonnes of carbon dioxide (CO2) emissions.2 Ammonia production accounts for 1.8% of global CO2 emissions this year, 80% of which are from the isolation of hydrogen needed for ammonia synthesis.

The power of green ammonia: How can it be used?

The advent of the Haber-Bosch process in the early 20th century allowed the rapid production of ammonia from hydrogen and nitrogen, providing an artificial way to fix nitrogen in a form easily accessible to plants when injected directly into arable land. .

Today, about 80% of all ammonia produced is used for agricultural fertilizers3however, the new purpose of ammonia was discovered with the development of technologies for alternative fuels, namely hydrogen.

Hydrogen (H2) is the most abundant element in the universe and its combustion leads to water as a by-product. It can be used in sectors of the economy that have historically been difficult to decarbonize, such as steel production and maritime transport. It can also serve as a carrier for long-term storage in the energy sector. Governments and industries around the world are increasingly focusing on building the infrastructure needed to support the hydrogen economy.

Among the main obstacles to the widespread use of hydrogen is its ability to move and store before its final use. Hydrogen can be transported in tankers as a liquid, which can increase the tanker’s load fivefold. However, liquid hydrogen requires temperatures below -253 ° C and this process involves high capital costs and uses about 35% of the total energy content.

Instead, ammonia can be a method of safely transporting hydrogen that requires only light pressure at ambient temperature to liquefy.

Ammonia is not only an agricultural fertilizer and an optimal carrier of hydrogen, which can compete with oil for this purpose, but can also be used as an alternative carbon-free fuel. It has 1.8 times the energy density of hydrogen and emits mostly water as a by-product of combustion.4

Ammonia could be the solution to the International Maritime Organization’s (IMO) promise to reduce carbon emissions by 50% before 2050.

Marine ammonia market

AmmPower Corp., a clean energy company focused on green ammonia production, is active in all aspects of the ammonia market, including the production of green manure, carbon-free transport fuel and the cracking or removal of green hydrogen as ammonia.

The company is working to develop its own technologies to produce green ammonia and green hydrogen on a large scale, including research into unique catalytic reactions to reduce costs and use carbon credits in the renewable energy space.

AmmPower will develop port facilities in strategic locations conducive to the development of large-scale renewable energy projects.

The company currently has a Memorandum of Understanding (MOU) with Porto Central in Brazil to install the world’s leading green ammonia facility in the port. This facility will produce approximately 4,000 tons of green ammonia per day, serving the ship’s fuel industry, providing green manure to the Brazilian market and allowing the export of green ammonia as an energy source. With a draft of up to 25 meters, the port will be able to accommodate the largest and most modern ships in the world, and when it starts operating, Porto Central will be one of the most innovative ports in the world and a major center for green energy.

AmmPower also signed a letter of intent to develop another 4,000 tonnes of green ammonia a day in the Port of Southern Louisiana (PoSL). PoSL is the largest tonnage port in the Western Hemisphere and the second largest energy port in the United States. This facility will be one of the first of its kind to help transition one of the world’s largest ports to a source of green energy.

AmmPower will be an early maritime leader in the green shipping industry and a key leader in the movement of green hydrogen as an energy source.

Ammonia fertilizer market

AmmPower is currently developing a modular, scalable green ammonia plant called IAMMTM (Independent machine for ammonia production). As the acronym suggests, IAMM is an independent system that will be able to generate four tons of ammonia a day.

The IAMM system creates green ammonia for use as fertilizer in the agricultural industry by renewable energy and water electrolysis. This means that fossil fuels are not used to generate the hydrogen needed for ammonia synthesis and no carbon emissions are produced.

One of the most important ways for energy independence is for countries to build their own renewable energy infrastructure. The AmmPower IAMM is designed to produce green hydrogen by electrolysis, isolate nitrogen from the air and convert it to ammonia using renewable electricity, making it independent of both natural gas and oil prices.

By developing, building and marketing smaller ammonia production units that are financially viable for the customer, AmmPower will disrupt the market for anhydrous ammonia fertilizers.

This strategy will allow economical production of anhydrous ammonia without having to rely on the availability and transportation problems encountered in the ammonia supply chain today.

IAMM will allow farmers and fertilizer producers to take control of their own ammonia supplies for the first time.
