Newlight

Newlight is a maritime energy technology company developing hydrogen-hybrid propulsion systems for existing commercial vessels. Its retrofit technology integrates controlled hydrogen injection with conventional marine diesel engines, allowing ships to reduce diesel consumption and emissions without replacing the main propulsion system. The company combines hydrogen supply equipment, control software, sensors, and safety systems in a retrofit package designed for installation during planned vessel maintenance. In 2026, Newlight reported commercial voyage results showing reductions in diesel consumption and onboard carbon dioxide emissions. The company focuses primarily on improving the efficiency and emissions performance of the existing global shipping fleet.
