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.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., For many years, we’ve flagged the fact that scrubbers account for disproportionately large emissions of hazardous and acidifying substances into the marine environment.

Researchers devise seawater-resilient bipolar membrane electrolyzer for turning seawater into hydrogen

Green Car Congress

The design proved successful in generating hydrogen gas without producing large amounts of harmful byproducts. Generation of H 2 and O 2 from untreated water sources represents a promising alternative to ultrapure water required in contemporary proton exchange membrane-based electrolysis. —Marin et al.

New study confirms extensive gas leaks in the North Sea; recommends stricter guidelines for handling of abandoned wells

Green Car Congress

Researchers from the GEOMAR Helmholtz Center for Ocean Research Kiel have found that considerable quantities of the greenhouse gas methane escape uncontrolled into the water from abandoned oil and gas wells in the North Sea. The most important factor was indeed the distance of the wells from the gas pockets. Böttner, C.,
