For more than 10 years the Viking cruise ferry MV Mariella has been successfully operating her four S.E.M.T. Pielstick 12VPC2.6.diesel engines with Humid Air Motor technology. This year the, Norwegian owned, purse seiner/trawler and factory vessel MV Kvannøy built in 2002, was converted to Humid Air Motor operation. NOx emissions were reduced by 61.3 per cent, a saving of 50 ton annually. The HAM system operates by saturating the incoming turbocharger charge air with sea water vapor before it enters the air box and then the combustion chambers. The result is a lower peak temperature in the combustion process thereby reducing NOx formation. The economic benefits of the change gives a theoretical payback time for the HAM retrofit of approx. 3 years.

Since 2008, there is a UK based shipping environmental charity called Greenwave that strives to develop policies that not only encourage but reward ship owners for the early adoption of technologies designed to reduce emissions. Their emphasis is on new technical solutions rather than improving existing best practices such as hull and propulsion machinery maintenance, weather routing etc.One of two wind related projects is Turbo-foil, which seeks to reduce the aerodynamic drag of ships. While much attention is devoted to hydrodynamic design, the aerodynamic design, streamlining of ships hasn't changed much over the years with the exception of warships, cruise ships and mega yachts. Tests carried out in the wind tunnel at the University of Auckland has identified where the turbulence is greatest, and where fairing should be mounted to reduce drag. According to Greenwave, practical tests demonstrate that Turbo-foil can reduce above deck drag by at least 20 per cent equivalent to an annual saving of 50 tons of fuel and 150 tons of CO2 production.

Projects running with NYK Line ships under the Japanese Ministry of Land, Infrastructure, Transport and Tourism are investigating technological developments to curtail CO2 emissions from marine vessels. In the main project, two NYK ships, are equipped with an air blower to supply air to the vessel's bottom to reduce frictional resistance. Mitsubishi Heavy Industries supplied the engines and is also participating in the experiment. It was decided that, a module carrier, would be best type of vessel for this experiment. she has a wide, shallow-draft hull minimizing the energy required by the electrically blower supplying air to the vessel's bottom and should better retain the supplied air under the vessel's bottom.
