As such, any increase in the cost of oil sparks even more interest in gasoline alternatives. Things like electric cars and hydrogen fuel cells are being talked about as feasible alternatives to oil. But, not lost in the mix are the biofuels, fuels made from biological ingredients instead of ...

Other biofuels include fatty acid methyl ester (FAME), a type of biodiesel derived from either vegetable oils or animal fats. Biomethanol is produced from agricultural residues, woody biomass, or byproducts from pulp mills. And biogas is produced through the anaerobic digestion of waste streams su...
Neat, planet-friendly policies, for the win. These biofuels sound all good. What is the downside? The cost. Currently biofuels, despite being faster, aren't cheap to produce because in the same way oil from the earth needs to be refined into its components, the biomass needs to be ...
Their theory was correct, and the results were groundbreaking. The natural gRNA complex was engineered into a chimeric single guide RNA (sgRNA), offering a simple and cost-effective method of genetic manipulation. Researchers only needed to provide a different guide RNA - which can be generated...
Unfortunately, prices will need to drop to about $30 per kilowatt before hydrogen is competitive with gasoline as a fuel; however, the National Research Council predicts that the cost of the hydrogen itself, measured on a per mile basis, could soon be as much as 50 percent lower than the ...
Cost-effectiveness.Producing bioethanol is cheaper than producing petrol, so combining the two could be a great way to cut expenses in the transportation industry. The same goes for biodiesel and diesel. What’s more, as stocks of fossil fuels run low, their prices w...
Biodiesel is not pure vegetable oil. Although raw vegetable oil has been used to fuel diesel engines in the past, it has usually caused problems. The raw fat or oil must first undergo a series of chemical reactions in order to become fuel. There are a few different ways to make biodiesel...
The fact is that California is running out of refineries. When they’re not closing, they’re being converted into biodiesel factories, taking advantage of the subsidies California and the federal government provide for such better-for-the-environment fuels. The stat...
