As transportation remains the leading greenhouse gas emitting sector in the United States, original equipment manufacturers are turning towards alternative fuel sources like hydrogen and biofuels to promote sustainable mobility. However, challenges arise in designing lubricating oils compatible with these advancements. Hydrogen, particularly, presents unique challenges due to its emulsification reaction with common lubricants, leading to acidic by-products that degrade lubricity and promote foaming behavior. Companies like Lubrizol Corporation and The Chemours Company have developed specialized lubricants to address these challenges by regulating water accumulation and inhibiting corrosions in hydrogen internal combustion engines. Furthermore, research is exploring the use of biolubricants to enhance environmental sustainability and reduce toxicity. While the potential for hydrogen as a fuel source in transportation is promising, ongoing research is crucial to understand its interactions with lubricants and other engine components for the reliable operation of hydrogen-powered vehicles.
