Greenhouse Gas Footprint News

As marine operators and euipment manufacturers continue to explore alternative marine fuels as a means to help lower vessel emissions, technology group Wärtsilä said it has initiated combustion trials using ammonia.As part of the tests, ammonia was injected into a combustion research unit to better understand its properties. Based on initial results, the tests will be continued on both dual-fuel and spark-ignited gas engines. These will be followed by field tests in collaboration with ship owners from 2022…

Furthering Royal Caribbean Cruises Ltd.'s commitment to reducing their greenhouse gas footprint by one-third per available passenger cruise day by 2015, the global cruise line announced that it is partnering with Ecospec to install a pilot test of their CSNOx system on Royal Caribbean International's Independence of the Seas. The CSNOx system was introduced by Ecospec in January 2009, and is an abatement technology reported to remove sulfur dioxide (SOx), oxides of nitrogen (NOx) and carbon dioxide (CO2) from engine emissions in one process. Royal Caribbean is the first cruise operator to initiate a feasibility study with Ecospec to explore the potential for installation of CSNOx systems on a cruise ship.
