Questions & Answers

Q1. What makes the GRE process of ethanol production different than others on the market?

A1. Quite simply, the required BTU's needed to produce a gallon of ethanol is less than the BTU's used by other known methods.  This technology makes ethanol production affordable and self sustaining.  Most ethanol production and extraction techniques require heat input to separate the ethanol from water after fermentation has taken place by taking advantage of the difference in boiling points between ethanol and water. Our technology works at standard pressure without heat.

Q2. How useful is the 50% ethanol produced with GRE units?  I thought it had to be 100% ethanol to mix with fossil fuels.

A2. Corn ethanol facilities are entering the market to purchase hydrous ethanol trasported to their facilities and are willing to pay market value.  They feed the hydrous ethanol into their product stream for sale in their markets.   Hydrous ethanol is an economic, environmentally friendly alternative form of energy.  We invite others to explore and consider how to utilize hydrous ethanol in their products including engines, generators, stoves, gel-fuel, etc.  

Q3. How do I determine the market value of the hydrous ethanol I produce?

A3.  Market value for your hydrous ethanol will be determined by a contract between you and the corn ethanol facility (facilitated by GRE) and is based on the spot value of ethanol at the time of sale.  Contact GRE for recent sales history.
Q4.  Shouldn't farmers grow corn for food instead of for making ethanol?
A4.  They can do both.  By taking some of the starch (which is easily fermentable) out of the corn to make hydrous ethanol and then mixing the concentrated left-over nutrients with cellulose-rich materials (an alternate energy source that cows can use), farmers can grow cows for food or dairy AND produce ethanol to meet our energy needs.  It turns out to be a "win-win" situation!  Check out for more information.
Q5.  If we use corn for fuel instead of food, won't it drive up the cost of all corn-derived food?

A5. No.  GRE's process of low-temperature extraction generates a high-protein livestock feed as well as hydrous ethanol from the same corn that would have been fed to the livestock.  This actually utilizes the corn better without increasing the price.  The nutrient-rich mash, when combined with conventional forages (cellulose that cows can utilize for energy), makes a superior livestock feed.  

Q6.  Doesn't it take more energy to produce ethanol from corn than the amount of energy in the ethanol?

A6.  Based on studies, large, conventional ethanol production facilities generate 1.3 BTUs of ethanol energy for every 1 BTU of energy needed for production.  GRE's patented extraction process and equipment is considerably more efficient, producing well over 2 ethanol BTUs for every BTU consumed during production.  

Q7.  Where can I learn more about the possibilities of hydrous ethanol?

A7.  Check out the webpage of HE Blends.
