DuPont's MOLYKOTE HP-300 Grease: A Milestone in Hydrogen Purity Standards

On January 21, 2025, DuPont (NYSE: DD) proudly announced that its MOLYKOTE HP-300 Grease has met the strict hydrogen purity standards outlined in ISO 146872019. This achievement comes after a collaborative development effort with HyCentA Research GmbH, which included creating a rigorous lubricant testing protocol aligned with these demanding standards.

The testing process involved exposing the MOLYKOTE HP-300 to hydrogen under high pressure conditions of 700 bar for several weeks. After this duration, a comprehensive analysis of hydrogen gas and particle contamination was conducted. The results revealed that the MOLYKOTE HP-300 did not significantly contaminate hydrogen, thereby ensuring its compatibility with essential hydrogen applications, such as fuel cell stacks.

The significance of this breakthrough is profound, especially in the context of hydrogen technologies. Pure hydrogen, while a promising energy source, can easily be tainted by contact with various materials, including lubricants. Such contamination could pose serious risks, as even minuscule impurities, at concentrations as low as 4 parts per billion, can compromise the integrity and performance of fuel cells.

The rigorous testing and validation of MOLYKOTE HP-300 offer a robust solution to this challenge. It is poised to be an invaluable lubricant for hydrogen-exposed components, particularly in sealing and threaded connections. This innovative grease not only minimizes contamination risk but also upholds the integrity of critical components within hydrogen systems.

Moreover, the MOLYKOTE HP-300 grease is engineered to excel under extreme conditions, making it an ideal choice for safe and reliable hydrogen storage and transport—paving the way for the broader adoption of hydrogen as a next-generation fuel option. Its formulation supports resistance against hydrogen and various chemicals while demonstrating outstanding performance even in low temperatures (down to -40 °C), which is crucial for applications like vehicle refueling.

Importantly, the MOLYKOTE HP-300 is designed not to contribute to hydrogen embrittlement, ensuring compatibility with a wide range of materials, including elastomers and plastics. This characteristic is vital in preventing potential failures within hydrogen systems.

By significantly reducing the risk of contamination within hydrogen systems, DuPont is playing a pivotal role in promoting cleaner energy solutions. The introduction of MOLYKOTE HP-300 represents a crucial advancement that meets the stringent requirements of the hydrogen energy sector.
