International Innovation: The Rise of Green Ammonia

A New Carrier for Renewable Energy: ‘Green Ammonia’ is Greening the Global Shipping Industry

The global shipping industry is rapidly turning to ‘Green Ammonia’ to reduce its historic reliance on fossil fuels. It is made with renewable energy like solar or wind power and emits almost no carbon dioxide during use.

Green ammonia may be a key solution for lowering carbon emissions from ships, crucial to global trade, and could significantly impact the global energy transition.

International energy companies and shipping giants are investing significantly in specialized infrastructure for green ammonia-powered engines and ports.

Challenges: Despite being a zero-carbon fuel, its toxicity and high storage costs hinder commercialization. However, scientists are working tirelessly to improve safety standards.

Green ammonia commercialization will enhance global trade sustainability and advance the energy transition.

According to the International Maritime Organization (IMO), about 3% of global carbon emissions come from the shipping industry. To alleviate this pressure, several international energy companies, including Germany’s Green Energy Future Inc., and major shipping companies have announced billions in investments to create specialized infrastructure for green ammonia-powered engines and ports. Major ports like Singapore and Rotterdam plan to create specialized terminals for a new fuel by 2030, as reported in the Journal of Maritime Innovation.

However, there are several challenges to the successful commercialization of this technology.

• First, the toxicity of ammonia and the high pressure and temperature required for its storage require high safety standards for its use on ships.
• Second, the cost of producing green ammonia is currently about three times higher than that of conventional marine fuels. Scientists are conducting relentless research to improve safety measures and production efficiency. Researchers at MIT are developing a catalyst that could lower ammonia production costs by up to 25%.
