When combusted, this carbon is re-released into the atmosphere, closing the carbon cycle and making biofuels carbon neutral under some conditions. [3] First generation biofuels such as biodiesel [4] are produced directly from crops, such as cereals, maize, sugar beet and cane, and rapeseed. Second generation fuels are produced from byproducts ...
Neste has estimated that the use of NExBTL diesel cuts greenhouse gas emissions by 40 to 90 percent in comparison to fossil based diesel. [8] Due to the chemistry of the process, the renewable diesel is pure alkane and contains no aromatics, oxygen (although oxygen would have promoted cleaner combustion [9]) or sulfur. [3] [dead link ]
PBRs is an easier system to be controlled compare to the raceway pond system, yet it costs a larger overall production expenses. [citation needed] The carbon emissions from microalgae biomass produced in raceway ponds could be compared to the emissions from conventional biodiesel by having inputs of energy and nutrients as carbon-intensive. The ...
According to the Renewable Fuel Standards Program Regulatory Impact Analysis, released by the Environmental Protection Agency (EPA) of the United States in February 2010, biodiesel from soy oil results, on average, in a 57% reduction in greenhouse gases compared to petroleum diesel, and biodiesel produced from waste grease results in an 86% ...
The Washington, D.C., environmental group, compared ethanol, biodiesel and renewable diesel emissions from 226 reporting plants to those of oil refineries, based on data reported to the U.S ...
Turmoil in the biomass-based diesel sector, an umbrella term for renewable diesel and biodiesel, could become a roadblock to future investments in biofuels, the U.S. Energy Information ...
Algae can be produced in ponds or tanks on land, and out at sea. [78] [79] Algal fuels have high yields, [80] a high ignition point, [81] can be grown with minimal impact on fresh water resources, [82] [83] [84] can be produced using saline water and wastewater, and are biodegradable and relatively harmless to the environment if spilled.
Strategic Biofuels LLC, a project development company, announced on Friday it plans to develop a renewable diesel plant in Louisiana that will produce up to 32 million gallons per year of ...
