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.

Ocean Salinities Show an Intensified Water Cycle; Large Salinity Changes Will Eventually Influence Ocean Circulation

Green Car Congress

A new study co-authored by CSIRO (Australia) scientists Paul Durack and Dr. Susan Wijffels finds evidence that the world’s water cycle has already intensified. The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. Durack and Wijffels. ºC since 1950.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Andrews have demonstrated that ammonia can be synthesized directly from air (instead of N 2 ) and H 2 O (instead of H 2 ) under a mild condition (room temperature, one atmosphere) with supplied electricity which can be obtained from renewable resources such as solar, wind or marine. —Lan et al.
