Utilize the power of green ammonia

AmmPower Brings clean energy to the world with the power of green ammonia, a natural chemical that is 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 produced, hydrogen and nitrogen atoms combine to form the ammonia product NH.3.. The color prefix refers to the energy source used to power the process, defines how hydrogen was obtained, and represents the impact of associated emissions.

The traditional gray ammonia synthesis process uses fossil fuels, mainly natural gas, as raw materials and produces hydrogen by steam reforming. This is a carbon-intensive process where the associated upstream carbon emissions problem remains, even if the ammonia reaction itself does not produce emissions. Blue ammonia is a similar process, but carbon-related emissions are captured, stored or utilized elsewhere. In fact, according to the Energy Information Administration (EIA), 98% of ammonia plants around the world use fossil fuels as a source of hydrogen for the ammonia synthesis process.1

However, green ammonia uses green hydrogen and green energy to power the synthesis process.To make hydrogen green, you need to produce hydrogen without using fossil fuels or producing anything that contains carbon. Greenhouse gas.. The most common way to get clean hydrogen is to electrolyze water (H).2O) Simply put, it involves passing an electric current through the water, thereby “electrolyzing” the water and separating the hydrogen and oxygen atoms.

Effect of ammonia

Ammonia is the second most widely used inorganic chemical in the world. In 2020, 176 million tons of ammonia will be produced and about 500 million tons of carbon dioxide (CO)2) Emissions.2 Ammonia production accounted for 1.8% of the world’s CO2 Emissions of the year, 80% of which were due to the separation of hydrogen required for ammonia synthesis.

The Power of Green Ammonia: How Can It Be Used?

With the advent of the Haber-Bosch process in the early 20th century, it became possible to rapidly produce ammonia from hydrogen and nitrogen, an artificial method of fixing nitrogen in a form that plants could easily absorb when injected directly into the soil of agricultural land. Was provided.

Currently, about 80% of the ammonia produced is used in agricultural fertilizers.3However, the development of alternative fuel technology, hydrogen, has discovered a new purpose for ammonia.

Hydrogen (H2) Is the most abundant element in the universe, and its combustion produces water as a by-product. It can be used in economic fields such as steelmaking and sea transportation, which have historically been difficult to decarbonize. It can also serve as a long-term storage medium for the power industry. Governments and industries around the world are increasingly focusing on building the infrastructure needed to support the hydrogen economy.

Among the main barriers to the widespread use of hydrogen is the ability to move and store hydrogen before it is used for end use. Hydrogen can be transported to the tanker as a liquid, doubling the load capacity of the tanker. However, liquid hydrogen requires temperatures below -253 ° C, the process has a high cost of capital and uses about 35% of the total energy content.

Instead, ammonia is a safe way to transport hydrogen and requires only a small amount of pressure at ambient temperature to liquefy.

Ammonia is an agricultural fertilizer and is not only the optimal carrier of hydrogen for this purpose, comparable to petroleum, but can also be used as an alternative carbon-free fuel itself. It has an energy density 1.8 times that of hydrogen, and when burned, it releases water mainly as a by-product.Four

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

Ammonia Maritime Market

AmmPower Corp., a clean energy company focused on the production of green ammonia, is active in all aspects of the ammonia market, including the production of green fertilizers, carbon-free transport fuels, and the “cracking” or transfer of green hydrogen. As ammonia.

The company is working on developing unique technologies for large-scale production of green ammonia and green hydrogen, including research on unique catalytic reactions to reduce costs and leverage carbon credits in the renewable energy sector. ..

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

The company is currently signing a Memorandum of Understanding (MOU) with Porto Central, Brazil, with the aim of installing a world-leading green ammonia facility in the port. The facility will produce approximately 4,000 tons of green ammonia per day, fuel the shipping industry, provide green fertilizer to the Brazilian market and enable the export of green ammonia as an energy source. With a draft of up to 25 meters, the port can accommodate the world’s largest and most modern vessels, and while in operation, Porto Central is one of the world’s most innovative ports and has become a major green energy hub. Become.

AmmPower has also signed an intention to develop a 4,000 tonnes of green ammonia facility per day in a port in southern Louisiana (PoSL). PoSL is the largest tonnage port in the Western Hemisphere and the second largest energy transport port in the United States. This facility will be one of the first of its kind to help migrate one of the world’s largest ports to a green energy source.

AmmPower was an early maritime leader in the green shipping industry and a major leader in the movement of green hydrogen as an energy source.

Ammonia fertilizer market

AmmPower is currently developing a modular and scalable green ammonia production unit named IAMM.TM (Independent ammonia maker). As the acronym indicates, IAMM is an independent system capable of producing 4 tonnes of ammonia per day.

The IAMM system produces green ammonia for use as fertilizer in the agricultural industry from renewable energy and electrolysis of water. This means that there is no fossil fuel used to produce the hydrogen needed for ammonia synthesis and no carbon emissions occur.

One of the most important ways for energy self-sufficiency is for each country to build its own renewable energy infrastructure. The AmmPower IAMM unit is designed to produce green hydrogen by electrolysis, separate nitrogen from air, and use renewable electricity to convert them to ammonia, from the prices of both natural gas and oil. Independent.

AmmPower disrupts the anhydrous ammonia fertilizer market by developing, building and selling small ammonia production units that are economically feasible for customers.

This strategy allows the economical production of anhydrous ammonia without relying on the availability and transportation issues encountered in today’s ammonia supply chain.

For the first time, IAMM will allow farmers and fertilizer manufacturers to control their ammonia supply.
