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.

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.

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.

WinGD and HHI-EMD extend collaboration to develop sustainable two-stroke engine technology

Green Car Congress

Marine engine designer and power system integrator WinGD and engine builder Hyundai Heavy Industries’ Engine Machinery Division (HHI-EMD) will strengthen their collaboration by partnering to develop environmentally sustainable two-stroke engine technology. It is possible to recirculate exhaust gas up to a maximum rate of 50% mass flow.

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development.

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.

European Council and Parliament agree to limit sulfur content of marine fuels to 0.5% for all ships by 2020

Green Car Congress

European governments have agreed on legislation to limit the maximum sulfur content of marine fuels to 0.5% (5,000 ppm) for all ships from 2020, down from currently 3.5% According to the compromise, member states should endeavor to ensure the availability of the required marine fuels. for cargo vessels and 1.5% for passenger ships.
