Alternative Petroleum Technologies S.A. (APT) and its partner, ITI S.r.l., completed a successful demonstration of various versions of its products on board a commercial container ferry using an emulsified diesel marine fuel. The emissions were measured by ISMAR Chimica Spa, an independent ISO17025:2005 certified laboratory. The engine load was measured using the ship's instruments. The emulsified fuels gave a reduction in PM 10 emissions of 34% (for 13% water) and 43% (for 18% water) and a reduction in NOx emissions of 16% (for 13% water) and 27% (for 18% water). A fuel efficiency advantage of more than 5% was recorded.
