  • effects of land use change on the carbon balance of 1st Generation Biofuels an analysis for the european union combining spatial modeling and lca
    Biomass & Bioenergy, 2013
    Co-Authors: Florian Humpenöder, Rüdiger Schaldach, Yalda Cikovani, Liselotte Schebek
    Abstract:

    Abstract Biofuels are considered as an important option for the mitigation of climate change. However, the negative impact of land-use change (LUC) on soil and vegetation carbon pools may jeopardize the potentially achievable savings of greenhouse gas (GHG) emissions. In this study the impact of GHG emissions from LUC on the overall GHG performance of 1st Generation Biofuels was analyzed for the European Union (EU). The scenario-based analysis was done by coupling a spatial land-use model to a Life Cycle Assessment (LCA) of Biofuels. The biofuel demand in the scenarios was derived from figures for the transport sector of the EU-27 Member States. The calculation of GHG emissions was performed with a Geographic Information System. Finally, these results were integrated into the LCA approach of the EU Renewable Energy Directive (RED). Without taking LUC into account, the average GHG emission saving compared to fossil fuel use amounts to ∼50%. In this case the mandatory 35% emission saving target laid down in the RED would be fulfilled. If LUC is considered, this target is reached under none of the simulated biofuel scenarios. In the most realistic scenario the GHG emission savings from 1st gen. biofuel use compared to fossil fuel use range between −2% and 13%. Based on our findings, we conclude that national policy plans for biofuel use should be reconsidered and revised as in their current form they do not provide an adequate measure for the mitigation of global warming on EU-level.

  • A Broad Introduction to First-, Second-, and Third-Generation Biofuels
    Recent Advancements in Biofuels and Bioenergy Utilization, 2018
    Co-Authors: Sonil Nanda, Rachita Rana, Prakash Kumar Sarangi, Ajay Kumar Dalai, Janusz A Kozinski
    Abstract:

    The aggregating usage of fossil fuels, rising demand for energy, fluctuating fuel prices, and increasing emissions of greenhouse gases are some of the concerning factors contributing to a shift in the interest from fossil fuels to Biofuels. Biofuels are carbon-neutral sources of energy as the CO2 emissions resulting from their combustion is utilized by the plants during photosynthesis leading to no net increase in atmospheric CO2 levels. It is indispensable to focus on the new approaches to the research, development, and production of Biofuels and their processing technologies to reshape a sustainable bioeconomy. Biofuels can be categorized into first, second, and third Generation depending on the feedstock used for their production. The product range for first-Generation Biofuels is largely limited to ethanol produced from corn and distillers grains. In contrast, the second-Generation Biofuels are produced from non-food residues or lignocellulosic biomass such as agricultural biomass and forestry refuse, as well as energy crops. The third-Generation Biofuels are produced from algae, sewage sludge, and municipal solid wastes. This chapter comprehensively focuses on various first-, second-, and third-Generation Biofuels with emphasis on their biomass sources, fuel properties, and applications. The fuel products broadly discussed in this chapter are ethanol, butanol, bio-oil, biodiesel, algal oil, hydrogen, biomethane, and aviation fuel.

  • production of first and second Generation Biofuels a comprehensive review
    Renewable & Sustainable Energy Reviews, 2010
    Co-Authors: Vaibhav V. Goud, Pravat Kumar Rout, S N Naik, Ajay Kumar Dalai
    Abstract:

    Sustainable economic and industrial growth requires safe, sustainable resources of energy. For the future re-arrangement of a sustainable economy to biological raw materials, completely new approaches in research and development, production, and economy are necessary. The 'first-Generation' Biofuels appear unsustainable because of the potential stress that their production places on food commodities. For organic chemicals and materials these needs to follow a biorefinery model under environmentally sustainable conditions. Where these operate at present, their product range is largely limited to simple materials (i.e. cellulose, ethanol, and Biofuels). Second Generation biorefineries need to build on the need for sustainable chemical products through modern and proven green chemical technologies such as bioprocessing including pyrolysis, Fisher Tropsch, and other catalytic processes in order to make more complex molecules and materials on which a future sustainable society will be based. This review focus on cost effective technologies and the processes to convert biomass into useful liquid Biofuels and bioproducts, with particular focus on some biorefinery concepts based on different feedstocks aiming at the integral utilization of these feedstocks for the production of value added chemicals.
