IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The IEA said that this reflects the continued domination of fossil fuels—particularly coal—in the energy mix and the slow uptake of other, lower-carbon supply technologies. Engine downsizing and weight reduction represent around 30% of that potential collectively. In 1990 the underlying carbon intensity of supply was 57.1

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Alcohol fuels can also be produced from natural gas or coal. These extreme downsizing indicates the potential of a SI, knock-free engine, operating at the same peak pressure as the diesel engine and higher engine speeds. More modest downsizing up to 5 liters could offer a practical solution. In this manner a 3.6

Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

Large scale production of methanol from natural gas and coal is a well-developed. Sufficient feedstock of natural gas and coal exists to enable the use of non-renewable methanol as a transition fuel to renewable methanol from biomass, they suggested. Methanol from non-renewable coal or natural gas could be used as a bridging.

Full lifecycle CO2 of new Mercedes C-Class 10% less than outgoing model

Green Car Congress

Where energy resources are concerned, lignite, hard coal and uranium figure principally in car production. For example, the iron demand is less because the share of steel is less, while the bauxite demand increases because of the higher light alloy share. The new C-Class shows a slightly higher level in this respect than its predecessor.

ExxonMobil Outlook projects hybrids and advanced vehicles to account for nearly 50% of cars globally by 2040; fuel demand for for personal vehicles to peak and decline, while commercial transportation demand rises 70%

Green Car Congress

Vehicle downsizing could account for more than one-third of total projected fuel economy improvements through 2040. ExxonMobil projects that global electricity demand will rise by 80% through 2040 as economies and living standards improve, and consumers switch to electricity from other sources such as oil, coal or biomass.
