ORNL computational study finds 15% bio-oil mixture in two-stroke marine engines can cut NOx 13% with efficiency parity

Green Car Congress

A team at Oak Ridge National Laboratory (ORNL) has developed a new computational model of a two-stroke scaled marine engine, with reduced chemical mechanisms for diesel, biodiesel, bio-oil, and polycyclic aromatic hydrocarbons (PAH). This work aims to develop a computational model of a scaled marine engine.

Rio Tinto and bp to work together on one-year trial of B30 marine biofuel

Green Car Congress

Rio Tinto and bp have agreed to work together on a one-year marine biofuel trial to help reduce carbon emissions from Rio Tinto’s marine fleet. The fuel will be trialed on Rio Tinto’s RTM Tasman vessel on a mix of Transatlantic and Atlantic-Pacific routes, in one of the longest-duration marine biofuel trials to date.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. Olmer et al.
