Engineered geothermal does not rely on existing hot water sources. Rather, water is injected into the dry hot rocks that are much more common. Steam from recovered water drives turbines to produce electricity. Much of the water is recycled by re-injecting. The potentail looks very good for this technology.

With a high compression engine to take advantage of high octane, fuel economy on ethanol can be near that of fuel economy on gasoline. But most flex fuel engines are designed for optimum fuel economy on gasoline. That’s why they get much worse fuel economy on E85. A variable compression engine […]

Researchers at Iowa State University are developing a catalyst that can be more selective in producing ethanol from syngas rather than other products. Through gasification, syngas can be produced from almost any organic material including waste materials. This technology ofr gasification is already in use and well developed. Syngas can be […]

Here is yet another ethanol feedstock that seems to hold great promise without the need for cellulosic ethanol technology (though it does yield large amounts of cellulose in addition to simple sugars). According to the linked article, Agave could produce much more ethanol per acre per year than corn or sugarcane, […]

Trials by Illinois researchers indicate the perennial grass known as Miscanthus could produce 2.5 times more biofuel energy per acre as compared to corn. This is with much less fertilization and erosion as compared to corn cropping. The variety used is sterile, and invasion of nearby fields has not been a […]

A Louisiana biofuel company focused on non-corn kernel feedstocks is arguing that ethanol import tariffs should be eliminated. They argue that more supply would permit and promote a building out of infrastructure for use of ethanol beyond 10% blending. Blender pumps, especially, would allow blending of gasoline and ethanol at various […]

Using Sweet sorghum as the main input, a Dominican agricultural complex plans to produce 100 million gallons of ethanol per year in addition to methane, hydrogen, and several types of livestock. Such an integrated system should be able to get more value from each ton of energy crop inputs.

A Florida company, Global Renewable Energy, is considering the kind of sorghum that produces lots of sugar-laden juice in the stems, similar to sugar cane. The ethanol would be made from this juice rather than grain. Ethanol is easier to make from these simple sugars, but the stems must be processed […]

Researchers at the University of Texas found that biogas (mainly methane) from livestock manure could produce about 2.4% of U.S. electricity needs while reducing greenhouse gas emmissions. A useful fertilizer would be left as a byproduct. Currently, a large portion of livestock manure is wasted or even produces environmental contamination.

This news is very important to the food vs. fuel debate. A new study lends support to the idea that native grasses can improve the soil while providing biomass for biofuel production at the same time. Soils currently too exhausted for food production could be restored while providing biofuel feedstocks. With […]

A tremendous amount of power is wasted in the form of heat from power plants. Changes in regulations related to retail pricing and emissions would likely encourage use of this heat resource through the market system. The rising cost of energy makes this more likely. Thomas Blakeslee’s article linked below explains […]

A major barrier for cellulosic ethanol from energy crops is transportation of huge volumes of biomass. KSU researchers want to find out whether pelletizing cellulosic biomass using proven technology could be an answer to this dilemma, reducing volume considerably. Pellets could also be handled with existing grain handling equipment, reducing infrastructure […]

In an exclusive interview, Richard Branson, head of the global Virgin Atlantic Airways, explains what sparked his mission to develop a “clean fuel” to replace the conventional “dirty fuels” that are currently “destroying our planet.”
The British-born entrepreneur says he has put 100 % of his airline’s profits toward “coming up with a fuel that can […]

T. Boone Pickens propese massive wind farms to free up natural gas that is now used for generating electricity. Much of that natural gas would be used to fuel CNG (Compressed natural Gas) vehicles. These vehicles are proven and available already in some states. Honda makes one suitable for commuting. Driving […]
