DuPont™ MOLYKOTE® HP-300 Grease Proven to Meet Strict Hydrogen Purity Standards
Pure hydrogen can be easily contaminated by any material it comes in contact with, including lubricants, which is why testing is critical to ensure purity for safety and performance. For hydrogen grades used in transportation applications, certain impurities with concentrations even as low as 4 parts per billion have the potential to compromise the integrity of the fuel cell. This rigorous assessment highlights DuPont™ MOLYKOTE® HP-300 Grease as a potential lubricant solution for hydrogen-exposed components in applications such seal and threaded connections, reducing contamination risk while maintaining the integrity of critical parts.
DuPont™ MOLYKOTE® HP-300 Grease has successfully passed hydrogen purity tests in accordance with ISO 14687:2019. In a third-party evaluation conducted over several weeks, MOLYKOTE® HP-300 was exposed to hydrogen at 700 bar, after which a hydrogen gas and particle analysis was performed. The third-party analysis confirmed that MOLYKOTE® HP-300 does not significantly contaminate hydrogen, eliminating potential issues in applications like fuel cell stacks.

This rigorous assessment highlights MOLYKOTE® HP-300 as a potential lubricant solution for hydrogen-exposed components in applications such seal and threaded connections, reducing contamination risk while maintaining the integrity of critical parts. The grease's performance in extreme conditions helps to support safe and reliable hydrogen storage & transportation and use of hydrogen as the next generation fuel.
In addition to its ability to help maintain hydrogen purity, MOLYKOTE® HP-300 offers resistance against hydrogen and many chemicals while providing excellent low temperature (-40°C) performance, which is important for applications such as vehicle refueling. It does not support hydrogen embrittlement and is compatible with a wide range of substrates including most elastomers and plastics.
By reducing the risk of contamination in hydrogen systems, DuPont is helping to advance cleaner energy solutions. MOLYKOTE® HP-300 Grease is well suited to meet the stringent demands of the hydrogen energy industry.
