Sentences with phrase «than ethanol»

There is a renewable resource out there that would be much better than ethanol.

• Ethanol production using wood biomass required 57 % more fossil energy than the ethanol fuel produced.

• Ethanol production using switchgrass required 50 % more fossil energy than the ethanol fuel produced.

• Biodiesel production using soybean required 27 % more fossil energy than the biodiesel fuel produced (Note, the energy yield from soy oil per hectare is far lower than the ethanol yield from corn).

«Cellulosic ethanol contains more net energy and emits significantly fewer greenhouse gases than ethanol made from corn.»

This «something» are alkylates, aromatics and reformates — which have been trading on commodity markets about $ 1.20 more per gallon than ethanol (last time I checked N.Y. Harbor prices).

This projected growth assumes that the anticipated expansion in cellulosic crop production would be used primarily for electricity generation rather than ethanol production.

Published in the online version of Science by scientists at the University of California - Merced, Stanford University and the Carnegie Institution, the study — «Greater Transportation Energy and GHG Offsets from Bioelectricity Than Ethanol» — recommends that the crops be grown on marginal agricultural land or abandoned agricultural lands, to prevent cutting into food crops for people.

The new study shows that burning biomass to produce electricity rather than converting it to ethanol (made from corn kernels or the other parts of the plant, so - called cellulosic ethanol) delivers 81 percent more miles per acre of transportation in electric vehicles than ethanol burned in internal combustion, even taking into account the lifetime costs of the expensive batteries available today.

From the atmosphere's point of view, growing biomass to burn in a power plant and using the electricity to move a car avoids 10 tons of carbon dioxide emissions per acre, or 108 percent more emission offsets than ethanol.

«The blend - stock can be mixed into gasoline at higher concentrations than ethanol's current limit of 10 percent; plus it can be added to diesel and jet fuel.

DMF may not yet be a household name, but thanks to newly improved production processes, this biofuel may some day prove even better than ethanol as a sustainable alternative to gasoline.

We have developed an innovative, rapid sol - gel method of producing hydroxyapatite nanopowders that avoids the conventional lengthy ageing and drying processes (over a week), being 200 times quicker in comparison to conventional aqueous sol - gel preparation, and 50 times quicker than ethanol based sol - gel synthesis.

Monolaurin was 5000 times more inhibitory against Listeria monocytogenes than ethanol (Oh & Marshall 1993).

«Wind power's ecological footprint is so small — a million times smaller than ethanol's — that if all the cars driven in the United States were battery - electric, they could be fueled by wind turbines whose total land footprint, not counting spacing in between, takes up less than 1.2 square miles, Stanford University environmental engineering professor Mark Jacobson found.»

Sacred Beef Takes Backseat in Climate Debate Swedish Chickens Get Life Cycle Analysis Swedes Conclude Beef Bigger Burden Than Ethanol Swedish Climate Carrots Delayed But Consumers Eager

Findings in terms of energy outputs compared with the energy inputs were: • Ethanol production using corn grain required 29 % more fossil energy than the ethanol fuel produced.

In addition to their findings on corn, they determined that making ethanol from switch grass requires 50 percent more fossil energy than the ethanol yields, wood biomass 57 percent more, and sunflowers 118 percent more.

David Pimentel, a professor of ecology at Cornell University who has been studying grain alcohol for 20 years, and Tad Patzek, an engineering professor at the University of California, Berkeley, co-wrote a recent report that estimates that making ethanol from corn requires 29 percent more fossil energy than the ethanol fuel itself actually contains.

If ingested, the so called toxic alcohols (other than ethanol) such as methanol, propanol, and ethylene glycol metabolize into toxic aldehydes and acids, which cause potentially fatal metabolic acidosis.

Butanol has a higher energy content per gallon than ethanol, and can be used directly in gasoline engines, making it a better choice.

The low energy required for this separation, says Renninger, is one of the cost advantages of making hydrocarbons rather than ethanol.

UCLA scientists have created E. Coli that produce butanol, which packs even more energy than ethanol.

That result contrasts sharply with a controversial study published just over a year ago in Science that suggested that a mixture of prairie grasses farmed with little fertilizer or other inputs would produce a higher net energy yield than ethanol produced from corn (Science, 8 December 2006, p. 1598).

And by the way, adding a copper - coated ruthenium catalyst can also convert the HMF to DMF (2,5 - dimethylfuran), a fuel that provides more energy than ethanol.

If DMF does pass that test, however, it could be available shortly and cost no more (and potentially less, depending on the utility of side products like HMF) than ethanol.

The combination of plug - in hybrids and bio-deisel (a much more energy - efficient fuel to make than ethanol) could significantly reduce developed world demand for oil for passenger transport.
