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 40-45% ethanol produced with GRE units? I thought it had to be 100% ethanol to mix with fossil fuels.
A2. Ethanol on it's own has a high octane rating. By adding water to the ethanol, it raises the octane rating by over 40%. Therefore, water has a proven ability for displacing diesel fuel through dual injection. Our tests are proving that over 50% of current diesel consumption could be displaced with a much cleaner and cheaper ethanol/water mixture. See our Products page for more details.
Q3. How do I convert my diesel engines to run on a diesel/ethanol dual injection?
A3. There are many duel-fuel injection systems on the market today for turbo/super charged diesel or gasoline engines. Utilization of these systems will significantly reduce your fuel costs and exhaust pollutants while increasing torque output and horsepower. GRE continues to perform automotive testing to maximize the use of hydrous ethanol coolant in duel-fuel injection systems and hopes to develop a fuel injection system of their own. New results will be posted as they become available. Follow us on Twitter or Facebook for up-to-date information.
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 and milk products AND produce ethanol to meet our energy needs. It turns out to be a "win-win" situation! Check out http://www.americancattlemen.com/articles/ethanol-impact-feed-prices 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 actually 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 2.5 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.
