Catastrophic news about biodiesel 7
Carbon Footprint of BiodieselA European Union document recently released to Reuters found that the emissions generated by biodiesel can be up to four times greater than diesel or gasoline. The study was not made public until Reuters used freedom of information rights.
According to reports by Reuters, the EU has found that burning forests to clear land results in carbon dioxide emissions that cancel out the benefits of biofuels.
The document says biodiesel made from soybeans can indirectly produce 339.9 kilograms of carbon dioxide emissions per gigajoule, Reuters reports. This is four times the amount of emissions of standard diesel, the report said.
While standard diesel or gasoline creates around 85 kilograms of carbon dioxide emissions, biodiesel from European rapeseed produces about 150.3 kilograms per gigajoule, according to the Reuters article.
A scientist involved with the research indicated that additional work needs to be done and that no final conclusions could be made on biofuel and its environmental impact, Reuters reports.

abomohra!
just think in the logic way, how soybean will produce CO2? This is a natural product, the other thing, to produce Biodiesel, what we want to use is Algaes, Hemp Seeds, WVO, etc. no crops grains. We need to put aside all the speculation, you know big Co. are paying whatever money is available to set back the green tech... have a good day
Dear MiguelAlfaro,
Thank you for your comment. I'm also wondering about this news. How is the natural product produces this a lot amount of CO2?!!! it is not logic to say this. And I agree you that we need to close the door of using edible plants for biodiesel production. Happy weekend.
I agree with MiguelAlfaro.
The US Environmental Protection Agency conclusion was that a 78% carbon emissions reduction, versus petrodiesel, is achievable.

Production of biodiesel from used cooking oils reduces carbon emissions by 90% (DTI). Every tonne of biodiesel used saves over 3 tonnes of carbon dioxide emissions, thereby reducing global warming.
I think, algae is the best feedstock for biodiesel production.Apart from co2 mitigation, they have several advantages over other biodiesel feedstocks. I came across an interesting article.Some interesting excerpts:
what does that fuel source look like? Ideally, it is:
1. Renewable,2. Continuously harvestable (not seasonal),3. Is ecologically friendly, using everything, wasting nothing, 4. Does not steal one resource for the sake of another (food versus fuel), 5. Competes with fossil fuels in the open market (does not require high oil prices to justify its production profitability),6. Produces more oil per acre than other bio mass sources.
7. Not limited by climate.
Currently, the only bio mass able to meet all of these requirements is algae. Grown in virtually all climates, algae has been shown to produce in excess of 130,000 gallons/acre/year. It can double in volume approximately every 52 hours. It consumes large quantites of greenhouse gas (570 metric tons of carbon dioxide per acre, per year). While oils from certain algae can be used to make food supplements or cosmetic oils, it is not a food source and does not compete with food sources such as corn, soy or palm. Using newly developed bioreactor technologies, algae based fuel oils can compete in the sub-$50/barrel market. Done properly, algae grown in a closed loop system is able to be harvested while recovering CO2, O2, and water for future use. In addition to the production of a fuel oil that does not require transesterfication, by-products of the production process may include methane, butanol, industrial grade charcoal and/or synthesis gas.
Thanks a lot Wasana and James for your comments. Really, they are very useful.
there's guys on youtube making hydrogen generators. Connect hydrogen to the air intake, and it burns both petroleum and hydrogen. Say it destroys the hydrocarbons in the combustion reaction, https://www.hydrolectricpower.com/GumBall_3000_Hollywood.html I don't know if there's anything to it, but it's along these lines so check it out and let me know.
