What is life cycle assessment of biofuels?
The concept of LCA and its application to biofuels. Life cycle analysis or assessment (LCA) is an internationally renowned methodology for evaluating the global environmental performance of a product, process or pathway along its partial or whole life cycle, considering the impacts generated from “cradle to grave”.
How is electricity produced from biofuels?
Biomass is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity.
Can biofuel be used for electricity?
The term biofuels usually applies to liquid fuels and blending components produced from biomass materials called feedstocks. Most biofuels are used as transportation fuels, but they may also be used for heating and electricity generation.
What is biofuel energy?
biofuel, any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.
What is biofuel life cycle analysis?
Biofuel Life Cycle Analysis accounts for inputs and outputs associated with feedstock production through to biofuel end use. Setting appropriate system boundaries can be challenging.
How much n is converted to N2O during the biofuel life cycle?
A major claim of this study [ 7•• ], which includes a rudimentary life cycle assessment, is that, averaged worldwide, 3–5% of newly fixed N associated with the biofuel life cycle is converted into N 2 O.
What is the global share of bioenergy in life-cycle assessment?
Total bioenergy curr ently has a global share of approx. 11% in total “inventory” part of life-cycle assessment. F or a more detailed description o n the standardized app roaches, methodologies, and terms for LCA see ISO 14000ff. Work of EEA addressed bioenergy more bro adly – see EEA 2006 and 2007.
Can biofuels replace fossil fuels in the transport sector?
The promotion of biofuels as energy for transportation in the industrialized countries is mainly driven by the perspective of oil depletion, the concerns about energy security and global warming. However due to sustainability constraints, biofuels will replace only 10 to 15% of fossil liquid fuels in the transport sector.
