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.

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).

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. Ships are responsible for about 800 million metric tons of CO 2 every year, roughly equivalent to the annual emission of Germany.

EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

In an EU-funded research project, an international consortium is aiming to develop new production methods for sustainable marine fuels to replace heavy fuel oils in shipping. IDEALFUEL seeks to develop methods to convert woody residual and waste materials such as sawdust and wood chips into renewable marine fuels.

UBC researchers find life-cycle GHG benefits of LNG in marine shipping only from high-pressure dual-fuel engines in ocean-going vessels

Green Car Congress

A life-cycle assessment of emissions from domestic and imported liquefied natural gas (LNG), and heavy-fuel oil (HFO) for marine shipping by a team from the University of British Columbia has found that only high-pressure dual-fuel (HPDF) engines robustly reduce well-to-wake GHG emissions by 10% compared with their HFO-fueled counterparts.

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. Flavio D.F. Finney, Brian C.

Bloom Energy and Samsung Heavy Industries team up to build ships powered by solid oxide fuel cells running on natural gas

Green Car Congress

SHI aims to be the first shipbuilder to deliver a large cargo ship for ocean operation powered by fuel cells running on natural gas. The IMO, an arm of the United Nations, is the global standard-setting agency for the safety, security, and environmental performance of international shipping.
