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., scrubbers—is responsible for up to 9% of certain emissions of carcinogenic and environmentally harmful substances in the Baltic Sea—considerably more than was previously known.

Rolls-Royce supplying two mtu gas engines for first LNG-hybrid tugboat

Green Car Congress

Rolls-Royce is supplying two mtu 16V 4000 M55RN gas engines to Sembcorp Marine Integrated Yard for the construction of the first liquefied natural gas (LNG)-hybrid powered tug. This is the first LNG-hybrid tug to be powered by mtu gas engines. The new engines are part of Rolls-Royce’s Green and High-Tech program.

ABS grants Alfa Laval the marine industry’s first approval in principle (AIP) for firing boilers with methanol

Green Car Congress

Maritime classification society the American Bureau of Shipping (ABS) has granted Alfa Laval the first marine approval for operating boilers on methanol. Marine boilers generate steam for auxiliary machinery for various ship services or, in some cases, for main propulsion. Source: Alfa Laval.

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. We know from Olmer et al.

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.

MAN ES and research partners to develop methanol retrofit solutions for medium-speed marine engines; CliNeR-ECo

Green Car Congress

MAN Energy Solutions will begin developing methanol retrofit solutions for medium-speed marine engines as part of a research association including WTZ Roßlau gGmbh and TU-Darmstadt. In addition, the project will evaluate the suitability of the methanol retrofit concept for other fuels (Ammonia-NH 3 , Liquefied Natural Gas-LNG).
