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. First, it contains very little sulfur.

Next-generation LNG carrier concept about 8% more energy efficient, with 5% more cargo

Green Car Congress

These developments were based on DNV GL’s integrated systems engineering approach COSSMOS; state-of-the-art computational fluid dynamics calculations (CFD); and a containment system design tailored to a specific operational profile and anticipated trades. —Martin Davies, the Project Manager at DNV GL. The primary fuel—i.e.

But about an hour later, I was smiling like a fool, the ocean wind blowing back my hair as I chugged down the road ringing the coast at about 25 m.p.h., I slammed on the brake, slowing the slide, but couldn’t get the engine to turn over again. I’d never driven a golf cart any significant distance, so when Ms.

MHI completes development of new-generation LNG carrier; reductions in size and weight, with more capacity and 20% lower fuel consumption than conventional ships

Green Car Congress

The continuous cover over the tanks improves aerodynamics by substantially reducing wind pressure which serves as a drag on ship propulsion. New Panamax is the term for the size limit of ships that will be capable of traveling through the Panama Canal after its planned expansion is completed in 2014: 366m in LOA, 49m in width and 15.2m

Gigantism Is a Never-Ending Temptation for Engineers and Designers

Cars That Think

Technically, it would have been possible, but such a ship would not fit through the Suez or Panama canals, and its draft would limit its operation to just a few ports. There are engineers who think that we will soon have wind turbines whose more than 200-meter diameter blades will fold, like palm fronds, in hurricanes.

Electric-Car Fans Rally Around the Volt - Green Inc. Blog - NYTimes.com

Tony Karrer Delicious EVdriven

Why pay $40K for a GM volt… which will look nothing more than a Malibu anyway and only get 40 miles before the gasoline engine kicks in. The fuel engine on the Volt is used to run the generator to recharge the battery when a trip exceeds 40 miles, and it’s rage on a full tank is around 400 miles. — Goodbye 2.
