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. —Pavlenko et al.

Rolls-Royce and Robert Allan present world’s first LNG-powered shallow-water push boat

Green Car Congress

Rolls-Royce and Canadian vessel designers Robert Allan have developed the world’s first shallow-water push boat powered by LNG natural gas engines. LNG (liquefied natural gas) is gaining traction in maritime circles, enabling operators to reduce emissions that are harmful to the environment and to the climate.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The difference helps explain how much industrial pollution influences clouds. NASA Earth Observatory.

Ensuring Underwater Robots Survive in Hot Tropical Waters

Cars That Think

The hot, humid environment of tropical marine areas such as Australia’s Great Barrier Reef can wreak havoc on the marine autonomous systems. Underwater and surface MAS are used for marine monitoring, locating objects such as mines on the seafloor, and rescuing swimmers.
