New GE combined cycle power plant delivers both flexibility and efficiency; enables greater use of wind, solar and natural gas on grid

Green Car Congress

By rapidly ramping up and down in response to fluctuations in wind and solar power, the technology will enable the integration of more renewable resources into the power grid, GE says. The steam turbine features a double flow side exhaust low pressure (LP) configuration and synchronous clutch. Click to enlarge.

Wärtsilä introducing first marine application of LNG-fueled version of world’s most efficient 4-stroke diesel

Green Car Congress

The combination of high efficiency, low fuel consumption, and the reduced level of exhaust emissions from operating on clean burning LNG, is expected to create low operating costs and a minimal environmental footprint. The Wärtsilä BWMS is designed to render the ballast water discharge harmless of invasive species.

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. This makes the clouds brighter, or more reflective.

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.

VW introducing 1.8L EA888 Gen 3 engine in 2014 Jetta, Passat and Beetle; driving impressions

Green Car Congress

Key advances for Gen 3 are in weight reduction, friction reduction, and the internal exhaust cooling system. Like its predecessor, the engine has a cast-iron cylinder block and an aluminum-alloy cylinder head which now has the exhaust headers cast integrally. Integrated exhaust manifold with cooling.

Graphene Flagship team develops powerful graphene-titania photocatalyst to reduce NOx

Green Car Congress

Organic pollutants, such as nitrogen oxides and volatile compounds, are a major cause of this, and they are mostly emitted by vehicle exhausts and industry. If the coating is applied to concrete on the street or on the walls of buildings, the harmless photodegradation products could be washed away by rain or wind, or manually cleaned off.
