  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]

    The so-called "third-generation biofuels", similar to second-generation biofuels with an emphasize on the use of algae and cyanobacteria as a source of biofuel feedstocks, have an additional advantage as they take up a relatively small fraction of space when compared to first and second-generation biofuel sources, and may also help to reduce seawater eutrophication.

  4. 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.

  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. Pellet fuel - Wikipedia

    en.wikipedia.org/wiki/Pellet_fuel

    From Spring 2015, any biomass owners—whether domestic or commercial—must buy their fuels from BSL (Biomass Suppliers List) approved suppliers in order to receive RHI payments. [72] The Renewable Heat Incentive scandal also referred to as the "cash for ash scandal", was a political scandal in Northern Ireland that centred on a failed ...

  7. Second-generation biofuels - Wikipedia

    en.wikipedia.org/wiki/Second-generation_biofuels

    Biomass in this context means plant materials and animal waste used especially as a source of fuel. First-generation biofuels are made from sugar-starch feedstocks (e.g., sugarcane and corn ) and edible oil feedstocks (e.g., rapeseed and soybean oil), which are generally converted into bioethanol and biodiesel , respectively.

  8. Biofuel in the United States - Wikipedia

    en.wikipedia.org/wiki/Biofuel_in_the_United_States

    Congress supported the renewable fuels program under the Energy Independence and Security Act of 2007 to contain particular annual volume standards for complete renewable fuel and also for the fixed renewable fuel groups of biomass-based diesel, biofuel, and advanced biofuel.

  9. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    The final two columns deal with the carbon footprint of the fuel. The fourth column contains the proportion of CO 2 released when the fuel is converted for energy, with respect to its starting mass, and the fifth column lists the energy produced per kilogram of CO 2 produced. As a guideline, a higher number in this column is better for the ...
