Abstract

A study of how lubricant additives impact hydrogen solubility is used to develop specialized lubricants for hydrogen internal combustion engine (H2ICE) applications to mitigate hydrogen leakage. An exemplary lubricant of a lubricating viscosity and formulated for a hydrogen internal combustion engine may include a base oil and a surfactant, wherein the hydrogen solubility of the lubricant is at least 7% as measured by Ostwald coefficient.
