As sustainable energy technologies advance, hydrogen is emerging as a major player in the transition to a low-carbon future.
However, the use of hydrogen requires sophisticated technological solutions to ensure safety and efficiency.
A crucial element of this system is lubricants, which must be specially formulated to operate in hydrogen-rich environments.
This article will explore the importance of safety and regulations for hydrogen use, then focus on hydrogen-safe lubricants.
Safety and regulations in the hydrogen world
Hydrogen is a highly flammable and reactive gas, which presents specific safety challenges.
The safe handling of hydrogen requires the adoption of stringent regulations that cover the entire lifecycle of hydrogen, from production to storage to transportation and end use.
International standards, such as those of the International Organization for Standardization (ISO), set specific standards for the safe handling of hydrogen, including the design of storage systems, refueling procedures, and requirements for materials used in these applications.
Regulatory authorities, such as the Occupational Safety and Health Administration (OSHA) in the United States and the European Agency for Safety and Health at Work, work to ensure that industrial practices comply with these regulations, reducing accident risks and improving overall safety.
A major concern is the prevention of explosions, which can occur when hydrogen comes into contact with oxygen in the presence of a spark.
Hydrogen-safe lubricants.
Lubricants used in hydrogen-rich environments must have specific characteristics to ensure safety and efficiency.
General lubricants can react with hydrogen, increasing the risk of fire and explosion.
Therefore, hydrogen-safe lubricants are formulated to be chemically stable and resistant to high pressures and temperatures.
Dupont’s Molykote® lubricants, for example, are designed for hydrogen contact applications and offer numerous advantages.
These include high thermal stability and resistance to oxidation, which is essential for operating in extreme conditions ranging from -70°C to over 300°C.
They also offer excellent compatibility with plastics and elastomeric materials, minimizing wear and extending the life of critical components.
Common challenges and solutions for hydrogen-safe lubricants include:
- Supporting equipment safety: The use of lubricants such as Molykote® and Krytox™ greases improves the safety of hydrogen refueling stations, ensuring proper release functionality in case of emergency and reducing the risk of hydrogen leakage along pipes by lubricating valve seals.
- Fuel cell unit efficiency: Semi-dry lubricants such as MOLYKOTE® PD-930 limit the risk of contamination in applications close to the fuel cell stack while maintaining high performance over time.
- Noise reduction: For applications such as hydrogen storage tanks in the automotive industry, MOLYKOTE® D-96 dry lubricant is effective in reducing noise between layers of material, improving comfort.
