I've just started reading about grass as biofuel. Anyone know of other new options?

Cellulosic Ethanol seems like the best overall bet for ethanol I have seen to date. I have heard that soft woods like willows and populars can be used as well. Woodlots that could be placed into a coppice culture would completely remove the need to plow and much of the fertilizer and pesticide issues that make corn ethanol such a problem.

Another issue that I am very interested in is wood chip gasification. Was very big back in Northern Europe in WWI and FEMA even updated the process under the Clinton Administration to provide the technology for simple localized fuel production from locally availble resources. It is simple enough that a bunch of friends and I built a working model in a long weekend.

Hope this helps!

I agree with OnestrawRob.  Cellulosic ethanol is the best option.  While ethanol is typically produced from the starch contained in grains such as corn and grain sorghum, it can also be produced from cellulose. Cellulose is the main component of plant cell walls and is the most common organic compound on earth. It is more difficult to break down cellulose to convert it into usable sugars for ethanol production. Yet, making ethanol from cellulose dramatically expands the types and amount of available material for ethanol production. This includes many materials now regarded as wastes requiring disposal, as well as corn stover, rice straw and wood chips or "energy crops" of fast-growing trees and grasses.

Producing ethanol from cellulose promises to greatly increase the volume of fuel ethanol that can be produced in the U.S. and abroad. A report found the land resources in the U.S. are capable of producing a sustainable supply of 1.3 billion tons per year of biomass, and that 1 billion tons of biomass would be sufficient to displace 30 percent or more of the country's present petroleum consumption. With continued advancements in pretreatment technology, fermentation, and collection and storage logistics, the commercial production of cellulose ethanol becomes more economically feasible.

Importantly, it offers tremendous opportunities for new jobs and economic growth outside the traditional "grain belt," with production across the country from locally available resources. Cellulose ethanol production will also provide additional greenhouse gas emissions reductions.

From California to Pennsylvanis, South Dakota to Florida, ethanol producers are rapidly commercializing technologies that utilize cellulose feedstocks.  Building upon the strong foundation grain-based ethanol technology has provided, the ethanol industry is rapidly developing and expanding the number of feedstocks available for ethanol production. 

 

Why choose ethanol?

FACT: With a 113 octane rating, ethanol is the highest performance fuel on the market and keeps today's high-compression engines running smoothly.

FACT: Using ethanol in place of gasoline helps to reduce carbon dioxide (CO2) emissions by up to 29% given today's technology. 

FACT: The U.S. imports 65% its petroleum needs today.

FACT: If ethanol were removed from the market, the shortfall would have to be made up from expensive imports.

FACT: In 2008, The U.S. ethanol industry last year added an additional 240,000 jobs, bringing the employment attributable to ethanol to almost a half a million.

Is there an ozone problem with ethanol?

Ethanol is one of the best tools we have to fight air pollution from vehicles. Ethanol contains 35% oxygen. Adding oxygen to fuel results in more complete fuel combustion, thus reducing harmful tailpipe emissions. Ethanol also displaces the use of toxic gasoline components such as benzene, a carcinogen. Ethanol is non-toxic, water soluble and quickly biodegradable.

Ethanol is a renewable fuel produced from plants, unlike petroleum-based fossil fuels that have a limited supply and are the major contributor of carbon dioxide (CO2) emissions, a greenhouse gas (GHG).

 

There is a lot more information about ethanol and the environment.  If you want to go to http://www.ethanolrfa.org/resource/facts/environment/ to read more.  This website gives you a lot of good information about ethanol and the environment.  You can also play around with the website, it has a lot of good information on it.

This report talks specifically about ethanol and the ozone layer.  You can read it in its entirety, but below are some important facts from the article. 

  • §        Wisconsin Department of Natural Resources (WDNR) data shows that ozone exceedance has decreased 16% since it adopted 10% ethanol (E10) in southern Wisconsin in 1994.
  • §        California Air Resource Board (CARB) data shows that ozone levels dropped SIGNIFICANTLY after E6 was put in use statewide in January 2004.
  • §        In six years leading u p to the use of E10, New York averaged 17 EPA 8-hour ozone exceedance days per year.  In the two years leading up to the use of E10 (2002/2003), New York averaged 21.5 ozone exceedance days per year.  In the two years since the switch to E10, New York has averaged 5.5 exceedance days per year, a 68% reduction.
  • §      Ethanol reduces carbon monoxide, an ozone precursor.
  • §      Ethanol reduces soot particulate pollution. (According to the American Lung Association, more than 2,000 studies link soot pollution to health problems like cancer, asthma and heart attacks).
  • §       Ethanol reduces dangerous hydrocarbon pollution.

This report shows that ethanol has air quality benefits for ground level ozone and soot PM reduction.  Ethanol is the way to go.  If we want a healthy enviroment, healthy children, and a healthy family, we need to make changes.  It can be as easy as filling up with ethanol, whether its E10 or E85, instead of gasoline.   We have to start somewhere.
