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., Comparison of loads (kg/year) of PAHs from direct discharges from ships and atmospheric deposition to the Baltic Sea. Ytreberg et al.

Study finds scrubbers have lower climate impact than low-sulfur fuel

Green Car Congress

A recent report from CE Delft, an independent research and consultancy organization, regarding the climate impact of Exhaust Gas Cleaning (EGC) systems for the marine industry. The study compares the results to the use of low-sulfur marine fuels and is made from a well-to-wake perspective in order to achieve an accurate comparison.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Small particles in exhaust from burning fossil fuels creates “seeds” on which water vapor in the air can condense into cloud droplets. C, or 1.8 ?F, F, since the late 1800s.). Diamond, M.

Among the engine’s potential applications are power washers, electric generators, lawn equipment, welders, marine propulsion and possibly some hybrid vehicles. The K6 engine uses six strokes instead of four to reduce the pressure of exhaust gases, which allows it to harvest more energy rather than expelling it with the gas.
