The International Maritime Organization (IMO) is aligning with the Paris Agreement to achieve net-zero emissions by 2050, necessitating legal measures to cut maritime shipping emissions by 15% between 2022 and 2030. Alongside these global efforts, we are excited to offer our Marine AUS40 for marine applications, providing a reliable solution that helps marine engines meet stringent emission standards. Our Marine AUS40 not only aids in preserving the health of our oceans but also enhances the efficiency of marinetime shipping.
What is Marine AUS40?
Marine AUS40, also known as Aqueous Urea Solution 40%, is a specialized high-purity urea solution tailored for marine Selective Catalytic Reduction (SCR) systems. These systems are critical in minimizing harmful nitrogen oxides (NOx) emissions from maritime engines and boilers.
Containing 40% urea mixed in deionized water, AUS40 is key in facilitating a chemical process that transforms NOx into nitrogen, water, and minimal carbon dioxide. This reaction significantly reduces the ecological footprint of marine operations.

Frequently Asked Questions
Q: What is Marine AUS40 and how does it differ from standard AdBlue®?
A: Marine AUS40 (Aqueous Urea Solution 40%) is a highly specialized, high-purity urea solution designed specifically for marine Selective Catalytic Reduction (SCR) systems. While standard automotive AdBlue® contains 32.5% urea, marine vessels, large ships, and locomotives utilize AUS40, which features a higher 40% urea concentration mixed with deionized water to handle heavy-duty maritime engines.
Q: Which international marine compliance standards does Blue Sky AUS40 meet?
A: Our Marine AUS40 is manufactured to meet the rigorous international ISO 18611-1:2014 standard. This ensures the fluid maintains the exact chemical purity required to safeguard your vessel's sensitive SCR catalytic converters against mineral contamination and performance degradation.
Q: How does using Marine AUS40 assist shipping lines with IMO regulations?
A: The International Maritime Organization (IMO) is enforcing strict measures to reduce shipping emissions globally. By injecting Marine AUS40 into the exhaust stream before it leaves the vessel, a chemical process converts harmful Nitrogen Oxides (NOx) into harmless nitrogen and water vapour, keeping your fleet compliant with international ecological frameworks.
Q: What are the key storage, handling, and freezing parameters for AUS40?
A: Blue Sky Marine AUS40 is completely non-toxic, non-flammable, non-hazardous, and safe to handle. It has a physical freezing point of approximately 0°C. To maintain optimal shelf life and prevent concentration breakdown, it should be stored in clean, dedicated stainless steel or high-density polyethylene (HDPE) tanks away from direct sunlight.
Q: Can we purchase Blue Sky Marine AUS40 in bulk for port refueling?
A: Yes. Blue Sky accommodates maritime refueling scales by offering Marine AUS40 in diverse formats. We supply heavy-duty 1,000L Intermediate Bulk Container (IBC) totes as well as specialized, high-volume bulk tanker solutions delivered directly to industrial ports and commercial refueling hubs.
