An overview of biodiesel the renewable source of fuel

There is no statutory volume requirement for "conventional" biofuel. In this lecture worldwide biofuel scenario is assessed by biofuel policies and standards. In other words, the fuel with a higher GHG reduction threshold can be used to meet the standards for a lower GHG reduction threshold.

Under a Creative Commons license Abstract Depletion of petroleum derived fuel and environmental concern has promoted to look over the biofuel as an alternative fuel sources.

EPA calculates and establishes RVOs every year through rulemaking, based on the CAA volume requirements and projections of gasoline and diesel production for the coming year.

Different biofuel processing techniques are also summarized. EPA continues to review and approve new pathways, including for fuels made with advanced technologies or with new feedstocks.

The Clean Air Act provides EPA authority to adjust cellulosic, advanced and total volumes set by Congress as part of the annual rule process. RINs are generated when a producer makes a gallon of renewable fuel At the end of the compliance year, obligated parties use RINs to demonstrate compliance RINs can be traded between parties Obligated parties can buy gallons of renewable fuel with RINs attached.

The statute also contains a general waiver authority that allows the Administrator to waive the RFS volumes, in whole or in part, based on a determination that implementation of the program is causing severe economic or environmental harm, or based on inadequate domestic supply. Previous article in issue.

The standards are converted into a percentage and obligated parties must demonstrate compliance annually. For example, fuels or RINs for advanced biofuel i. Brazil successfully boosted their bioethanol marketing by introducing flexible-fuel vehicles FFVwhich have a dedicated engine for both ethanol and gasoline.

Advanced pathways already approved include ethanol made from sugarcane; jet fuel made from camelina; cellulosic ethanol made from corn stover; compressed natural gas from municipal wastewater treatment facility digesters; and others.

The four categories of renewable fuel have the following assigned D-codes: Among other requirements, fuels must achieve a reduction in greenhouse gas GHG emissions as compared to a petroleum baseline.

Energy security and climate change are the two major driving forces for worldwide biofuel development which also have the potential to stimulate the agro-industry. Yet, marginal replacement of diesel by biofuel can prolong the depletion of petroleum resources and abate the radical climate change caused by automotive pollutants.

Discussing all this advantages and disadvantages of biodiesel, it is comprehended that, a dedicated biodiesel engine is the ultimate solution for commercializing biodiesel.

Cellulosic biofuel is assigned a D-code of 3 e.

U.S. Energy Information Administration - EIA - Independent Statistics and Analysis

So dedicated biofuel engine is a challenge for mass commercialization and utilization of biofuel. Minor modifications on the engine may not cost much; but continuous research and development is still needed.

Moreover, severe corrosion, carbon deposition and wearing of engine parts of the fuel supply system components are also caused by biodiesel. More information on RINs: But a complete substitution of petroleum derived fuels by biofuel is impossible from the production capacity and engine compatibility point of view.

Some guidelines on dedicated biofuel engine are prescribed.

Overview for Renewable Fuel Standard

Obligated parties must obtain sufficient RINs for each category in order to demonstrate compliance with the annual standard. Nonetheless, there are other problems associated with biofuel usage such as automotive engine compatibility in long term operation and also food security issues that stem from biofuel production from food-grade oil-seeds.

A similar approach can bring a breakthrough in biofuel commercialization and production.Energy Information Administration - EIA Hydroelectricity is the most prevalent renewable source in 19 states; wind in tags: electricity generation hydroelectric wind.
