Ammonia’s Evolution: The Future Of Green And Blue Ammonia Availability From 2030 To 2050- Report

Ammonia production primarily relies on the Haber-Bosch process, which combines nitrogen and hydrogen gases under high pressure and temperature. This process can be adapted to produce various types of ammonia, each with different environmental impacts. Brown ammonia is derived from fossil fuels like natural gas or coal, resulting in high carbon emissions. In contrast, blue ammonia is produced from fossil fuels with near-complete carbon capture and storage (CCS), reducing its carbon footprint but not eliminating it. Green ammonia, the most environmentally friendly option, is created using renewable energy sources such as wind, solar, or nuclear power through the electrolysis of water.

The global ammonia market is dominated by its use in fertilizers, which accounts for approximately 80% of total ammonia consumption. Other applications include explosives, plastics, synthetic fibers, resins, and refrigerants. Recently, ammonia has gained attention as a potential hydrogen carrier and marine fuel, adding to its versatility.

As of early 2023, around 200 million tonnes of ammonia are produced annually. There are currently 161 announced clean ammonia projects with a total capacity of 244 million tonnes per annum (MTPA). Most of these projects are still in the early stages of development, leading to uncertainty about their future success. Australia and the USA are significant players in the clean ammonia sector, with Australia aiming to produce 22% of global clean ammonia and the USA focusing on blue ammonia.

The production of green ammonia is currently more expensive compared to fossil-based ammonia, largely due to the high cost of renewable energy. However, as renewable energy costs decline and CO2 taxes become more prevalent, green ammonia is expected to become more economically competitive. Producing one tonne of green ammonia requires about 10 megawatt-hours of renewable electricity, necessitating a substantial increase in renewable energy capacity to meet future production goals.

Most clean ammonia projects are expected to come online by 2030, with project timelines varying from 2 to 24 years. The average construction time for these projects is around 13 years, with shorter durations typically associated with further advanced projects.

Future projections for clean ammonia supply in 2030 range from 34 to 51 MTPA, depending on various factors including project completion and market demand. A significant portion of this production is expected to be directed towards export markets. The distribution of ammonia use will likely shift as projects mature and new technologies emerge, influencing its role as a fuel, fertilizer, or energy carrier.

In terms of regional developments, Australia is positioning itself as a major clean ammonia producer with several large-scale projects underway. The USA is leading in blue ammonia production, with notable initiatives like the Ascension Clean Energy plant and the Port of Corpus Christi facility. Other countries, including Egypt, Kazakhstan, Mauritania, and Saudi Arabia, are focusing on green ammonia, while China and India are also increasing their clean ammonia production capacities.

The transition to clean ammonia faces several challenges, including technological risks and financial uncertainties. The competition with other hydrogen carriers and fuels will be influenced by market regulations and CO2 taxes, which will play a crucial role in determining the future viability and success of clean ammonia in the global energy landscape.
