Shipowners are ordering ships with alternative-fuel capability in ever increasing numbers, Clarksons Research has revealed.

The UK research arm of the shipbroking group said adoption has been on an upwards trajectory for years, despite uncertainty over future regulations and technology.

Clarksons Research analyst Marek Bak said: "LNG is the most popular option today, although other low and zero-carbon fuels are gaining traction, with notable new orders this year, alongside ongoing research and development."
