Accelleron

Accelleron develops high power turbocharging, fuel injection and digital solutions for heavy-duty engines, serving applications from 0.5 MW to more than 80 MW in marine, power generation, oil and gas, and rail. The company traces its engineering lineage to the world's first industrial turbocharger, pioneered by predecessor BBC in 1924, and has been independent since spinning off from ABB in October 2022.

Its installed base of 180,000 turbocharger units underpins a claimed market share of 40–60% across turbocharger segments. Beyond hardware, Accelleron works on engine performance optimization and digital tools aimed at reducing fuel consumption and emissions, with a stated focus on decarbonization and the energy transition in heavy-duty industries. A global service network of more than 100 locations supports the installed base across over 50 countries.

The company employs approximately 3,000 people and reports strategic investment in research and development alongside consistently high profit margins and strong cash flow generation. Technical work spans turbocharging technology, fuel injection, digital solutions, and service and maintenance engineering.
