Engine maker WinGD has revealed it is trying to move beyond dual-fuel engines into more flexible tri-fuel systems to meet the needs of the energy transition.

The Switzerland-headquartered company — 100% owned by China's state shipbuilding giant CSSC — is thinking about how it can develop systems for when bunkers such as ammonia and biomethane come onstream.

Dominik Schneiter, WinGD head of research and development, told TradeWinds that in 10 years the combustion engine will still be at the core of shipping propulsion.
