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 ...
The distinguishing feature is the technology involved in producing the intermediary product, rather than the ultimate off-take. A process producing liquid fuels from gas (normally syngas) is called a gas-to-liquid (GtL) process. [10] When biomass is the source of the gas production the process is also referred to as biomass-to-liquids (BTL).
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.

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]
The methanol used in most biodiesel production processes is made using fossil fuel inputs. However, there are sources of renewable methanol made using carbon dioxide or biomass as feedstock, making their production processes free of fossil fuels. [75] A by-product of the transesterification process is the production of glycerol. For every 1 ...
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 ...
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."
