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. First, it contains very little sulfur.

US MARAD study finds marine use of natural gas substantially reduces some air pollutants and slightly reduces GHG emissions

Green Car Congress

A recently released total fuel cycle analysis for maritime case studies shows that natural gas fuels reduce some air quality pollutants substantially, and reduce major greenhouse gas (GHG) emissions slightly, when compared to conventional petroleum-based marine fuels (low-sulfur and high-sulfur). This is an important consideration.

Toshiba’s SCiB Li-ion battery system Japan’s first recognized compliant with ClassNK guidline for marine vessels

Green Car Congress

At a time when pollution regulations are increasingly focused on the emissions ships generate, the SCiB will contribute to the protection of the marine and global environments. The certification is based on Class NK’s “Guidelines for Large-capacity Storage Batteries,” which requires use of a BMU in the system as a safety feature.

USC study shows promising potential for giant-kelp-based biofuel with depth-cycling approach

Green Car Congress

The National Research Council has indicated that generating biofuels from feedstocks such as corn and soybeans can increase water pollution. Farmers use pesticides and fertilizers on the crops that can end up polluting streams, rivers and lakes. —Brian Wilcox, co-founder and chief engineer of Marine BioEnergy.
