  2. Biomass (energy) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(energy)

    Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]

  3. Bioenergy with carbon capture and storage - Wikipedia

    en.wikipedia.org/wiki/Bioenergy_with_carbon...

    Biomass production is subject to a range of sustainability constraints, such as: scarcity of arable land and fresh water, loss of biodiversity, competition with food production and deforestation. [39] [obsolete source] It is important to make sure that biomass is used in a way that maximizes both energy and climate benefits. There has been ...

  4. Biogasoline - Wikipedia

    en.wikipedia.org/wiki/Biogasoline

    Diesel fuel is made up of linear hydrocarbons. These are long straight carbon atom chains which differ from the shorter, branched hydrocarbons that make up common gasoline. In a 2014 experiment, held at the University of California, Davis, researchers used a feedstock of levulinic acid to create biogasoline. [10]

  5. Bioenergy - Wikipedia

    en.wikipedia.org/wiki/Bioenergy

    The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3]

  6. Biofuel - Wikipedia

    en.wikipedia.org/wiki/Biofuel

    Biofuels are biomass-derived fuels from plants, animals, or waste; depending on which type of biomass is used, they could lower CO 2 emissions by 20–98% compared to conventional jet fuel. [68] The first test flight using blended biofuel was in 2008, and in 2011, blended fuels with 50% biofuels were allowed on commercial flights.

  7. Biomass to liquid - Wikipedia

    en.wikipedia.org/wiki/Biomass_to_liquid

    Fuel costs depend on how fast the grasses grow and other factors. [2] An estimated investment of over $325 billion (2008 basis) would be needed to build biofactories capable of producing the 65 billion gallons of biofuel needed to meet 2030 national goals.

  8. Biomass - Wikipedia

    en.wikipedia.org/wiki/Biomass

    Biomass is a term used in several contexts: in the context of ecology it means living organisms, [1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, [ 2 ] from plants and algae, [ 3 ] from plants and ...

  9. Biodiesel production - Wikipedia

    en.wikipedia.org/wiki/Biodiesel_production

    The process can tolerate water in the feedstock, free fatty acids are converted to methyl esters instead of soap, so a wide variety of feedstocks can be used. Also the catalyst removal step is eliminated. [9] High temperatures and pressures are required, but energy costs of production are similar or less than catalytic production routes. [10]
