Ammonia & green ammonia (NH3)

Ammonia (NH3) is a chemical compound that is important as an energy source and fuel for the transportation industry and power generation. Green ammonia is produced from the raw materials air and water using renewable energies and is playing an increasingly important role in the energy transition.

Definition of ammonia
Ammonia is a chemical compound of nitrogen and hydrogen that is used as a versatile energy source and raw material in industry. Green ammonia refers to the sustainable production of this compound from renewable energy sources, making it a more environmentally friendly alternative to conventionally produced ammonia.

Background / Origin
Traditionally, ammonia is mainly produced from natural gas and coal, which is ecologically questionable. The majority of global ammonia production, around 80%, is used in fertilizers. However, the importance of ammonia for achieving climate targets has encouraged research and development into green ammonia plants.

Green ammonia is produced decentrally using air and water and uses renewable energy. This production method reduces dependence on fossil fuels and contributes to reducing emissions in various sectors. Initiatives such as the CAMPFIRE alliance are actively working to expand the infrastructure and market share of green ammonia.

Properties
Ammonia is made up of one nitrogen atom and three hydrogen atoms (NH3). It is a colorless, highly volatile gas with a characteristic pungent odor. In liquid form, ammonia has a high energy density, which makes it an attractive energy source.

Chemically, ammonia is a basic molecule and reacts easily with water, forming ammonium ions. Its ability to split into water also makes it an effective source of hydrogen. The storage and transportation of ammonia is easier and cheaper than hydrogen, which qualifies it for various applications in the transportation and energy sectors.

Application and importance in the market
Ammonia has many applications, including use as a fuel in shipping and as a fuel in power plants. The market is currently dominated by fertilizer production, while only 20% of production is used for other applications. External demand for green ammonia is growing as it serves as a clean hydrogen supplier and can therefore play an important role in future energy systems.

International markets for green ammonia are developing, with companies such as MB Energy positioning themselves in the chemical's supply chain. Integration into existing energy systems is crucial to further drive the efficiency and uptake of green ammonia.

Differentiation from similar terms
- Hydrogen (H2): A pure energy carrier that can be used directly, while ammonia serves as a carrier substance for hydrogen.
- Conventional ammonia: Is produced from fossil fuels, in contrast to green ammonia, which is produced from renewable resources.

Summary
Ammonia is an important chemical with many applications in industry and as an energy source. Green ammonia, produced from renewable sources, has the potential to play a central role in the energy transition and reduce emissions. The development of decentralized production plants will be crucial to reduce dependence on fossil fuels and increase the market share of green ammonia.
