Study finds scrubbers have lower climate impact than low-sulfur fuel

Green Car Congress

SEPTEMBER 28, 2020

A recent report from CE Delft, an independent research and consultancy organization, regarding the climate impact of Exhaust Gas Cleaning (EGC) systems for the marine industry. The study compares the results to the use of low-sulfur marine fuels and is made from a well-to-wake perspective in order to achieve an accurate comparison.

OCTOBER 11, 2016

The newest class of ships from Royal Caribbean Cruises Ltd (RCL) will be powered by liquefied natural gas (LNG) and likely will introduce the use of fuel cell technology, ushering in a new era of shipbuilding that will significantly reduce greenhouse gas emissions. We believe fuel cells offer very interesting design possibilities.
