alternative bio fuels Frequently Asked Questions
What is your most preferred alternative fuel for vehicles?
i always hear alternatives like bio diesel and other kinds. what do you think is the best and the most preferred alternative?
The possible alternatives are electric, biofuels, and hydrogen. Among these, electric is undoubtedly the most promising.
Biofuels are good because the carbon released by burning them was taken out of the atmosphere by the plants, so in that sense there's no net emissions. However, you still have to put the energy into growing the biofuel crops. On top of that, you need to use more land for growing crops so that you have enough for biofuels and food, which means less land for grassland and forests.
For this reason, a study recently found that ethanol from corn and even switchgrass will contribute more to global warming than gasoline.

There are still good biofuels - for example using waste vegetable oil or creating ethanol from garbage (as discussed in the link above), but on a large scale, biofuels are simply not feasible.
Hydrogen could theoretically be a green fuel, but the problem is where to get the hydrogen from. Currently it mostly comes from natural gas, and the process emits as much CO2 as burning the natural gas itself for fuel, so there's no benefit. Theoretically you can get hydrogen from water by running a current through it, but with current technologies it takes far more energy to break the atomic bonds than you get by burning the hydrogen as fuel.
Plus there's no infrastructure to transport and store the hydrogen at refueling stations, and such an infrastructure would cost billions of dollars to build.
Electric cars are far more promising. The technology is advancing rapidly, and several reasonably affordable EVs with decent range and highway speed capabilities will be available within the next year or two (for example, the Miles Javlon, Aptera typ-1e, and ZAP Alias).
On top of that, because of the efficiency of large power plants and electric motors, studies have shown that even with the current US power grid mix (52% coal), EVs would emit less greenhouse gases than gas cars, hybrids, and even plug-in hybrids. And you can always build more renewable power plants to make the power grid greener. Plus the infrastructure (power grid) is already in place.
How can I bring my bio-diesel cost down?
My bio-diesel fuel is extremely expensive. The reason is that methanol costs me over $5 a liter and sodium hydroxide is also about $8 a kilogram. Is there a place where these chemicals are cheaper or is there an alternative method for producing bio-diesel? If there's an alternative method (a cheaper one of course), please name the chemicals and where I can buy them. I'm not interested in the "add another gas tank" method, so please skip that suggestion. (I don't work with gases, only liquids and solids please) Thanks.
Methanol can be bought through several types of distributors, as it is sold for several different uses. The price can vary from $2 a gallon to $4 a gallon.
Chemical Distributors- There are two major categories of chemical distributors; places that cater to laboratories and researchers and places that cater to industry.
If in doubt, go to www.forums.biodieselnow.com and ask your questions in the 'regional' forums for your area. Someone is likely to know where it's available in your location.
