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 MY Renewable Diesel (formerly NExBTL) is a vegetable oil refining fuel production process commercialized by the Finnish oil and refining company Neste.Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems.
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 ...
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
Carbon-neutral fuel is synthetic fuel—such as methane, gasoline, diesel fuel or jet fuel—produced from renewable or nuclear energy used to hydrogenate waste carbon dioxide recycled from power plant flue exhaust gas or derived from carbolic acid in seawater.
Electric vehicles are getting a huge amount of attention these days because of their energy efficiency and low emissions. But there's another emerging technology out there that makes the same ...
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 ...
Biodiesel currently has 3% of the diesel market in Germany and is the number 1 alternative fuel. [17] The German government has a Biofuels Roadmap in which they expect to reach 10% biofuels by 2010 with the diesel 10% coming from fuel made from vegetable oil. [18] From 2005 to 2007 a number of types of vegetable oil have doubled in price.
