New hydrogen engine delivers diesel-like torque in medium-duty trucks

Researchers demonstrated that the new hydrogen combustion engine, designed for average-sized commercial trucks and equipped with a turbocharger, can generate diesel-level torque, thereby preserving the existing internal combustion ecosystem while converting fuel carbon into water to approach near-zero CO₂ emissions; however, they also showed that the method of hydrogen production and NOx generated during combustion prevent it from guaranteeing completely zero emissions.
