The carbon emissions (carbon footprint) produced by biofuels are calculated using a technique called Life Cycle Analysis (LCA). This uses a "cradle to grave" or "well to wheels" approach to calculate the total amount of carbon dioxide and other greenhouse gases emitted during biofuel production, from putting seed in the ground to using the fuel ...
Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon dioxide (CO 2) that is produced. Greenhouse gas emissions from bioenergy can be low because when vegetation is harvested for bioenergy, new vegetation can grow that will absorb CO 2 from the air through ...
2), and carbon dioxide (CO 2), in the case of urea use, are produced. Selective catalytic reduction of NO x using ammonia as the reducing agent was patented in the United States by the Engelhard Corporation in 1957. Development of SCR technology continued in Japan and the US in the early 1960s with research focusing on less expensive and more ...
GreenFuel Technologies Corporation (GFT) was a startup that developed a process of growing algae using emissions from fossil fuels to produce biofuel from algae.. Based in Cambridge, Massachusetts, Greenfuel ceased operations on May 13, 2009, [1] [2] after having raised more than $70 million in investments, citing economic circumstances, and having run out of funds.
A 1965 report suggested synthesizing methanol from carbon dioxide in air using nuclear power for a mobile fuel depot. [62] Shipboard production of synthetic fuel using nuclear power was studied in 1977 and 1995. [63] [64] [65] A 1984 report studied the recovery of carbon dioxide from fossil fuel plants. [66]
Brazilian cerrado Amazon rainforest. The indirect land use change impacts of biofuels, also known as ILUC or iLUC (pronounced as i-luck), relates to the unintended consequence of releasing more carbon emissions due to land-use changes around the world induced by the expansion of croplands for ethanol or biodiesel production in response to the increased global demand for biofuels.
The amount of greenhouse gas emissions from deforestation is so large that the benefits from lower emissions (caused by biodiesel use alone) would be negligible for hundreds of years. [136] [138] Biofuel produced from feedstock such as palm oil could therefore cause much higher carbon dioxide emissions than some types of fossil fuels. [143]
The Intergovernmental Panel on Climate Change (IPCC) defines CCS as: "A process in which a relatively pure stream of carbon dioxide (CO 2) from industrial and energy-related sources is separated (captured), conditioned, compressed and transported to a storage location for long-term isolation from the atmosphere."
