ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

Additionally, LNG engines are tuned to either emit low nitrogen oxide (NO x ) emissions—at the cost of higher methane emissions in some cases—or to incorporate NO x reduction technologies such as exhaust gas recirculation (EGR) or selective catalytic reduction (SCR).

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

Green Car Congress

The low-diversion scenario assumes 2% diversion from the Panama and Suez canals between July and November of 2025. MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. ships diverting from prior routes to Arctic routes.

At the same time the continuous cover minimizes exposure of support structures and equipments, and it also facilitates reinforcement of overall strength to be effective in resisting ice impact load, thus making the system also suitable for LNG transportation in frigid or icy-water regions. in width, 26.0m in depth and 11.5m in LOA, 32.2m

Exhaust gas boilers and waste heat recovery equipment are also included in the design. meter beam allows passage through the existing Panama Canal locks. A single screw is directly driven by a dual-fuel, two-stroke, 22.9 MW engine developed specifically for LNG applications by MAN. The STREAM 4200 LNG’s 32.25-meter
