Biomass for energy production in the context of selected European and international policy objectives

Author
Arno Becker

Abstract: Biomass based energy production has attained a significant market share within the developing renewable energy market. In comparison to alternative renewable energy sources, biomass has several special features: it is not inexhaustible in the short term (limitation of arable land) and it is not only an energy source. Other usages like food or feed compete with energy production for this resource. A number of problems arise which have a direct impact on the fulfillment of policy objectives which are connected with its promotion. Primarily, the production of bioenergy has significant impacts on coupled biomassmarkets. Further, a change in production intensity or arable land use increases the use of nutrient loads and agro - chemicals. When evaluating renewable energy production, the wide range of political objectives has to be considered. Therefore, the focus of the overall study will be on three objective areas: promotion of the agricultural sector, environmental protection (reduction of GHG emissions) and maintenance of food supply security. The objective of this study is to combine an analysis of selected economic and ecological impacts of an increased biomass based energy production (primarily biofuels) under the assumption of European and international quantity targets by adjusting and applying the agricultural sector model CAPRI (Common Agricultural Policy Regional Impact Analysis). This poster intends to display the methodical approach of the intended analysis.

Characterization of dhaincha accessions based on morphological descriptors and biomass production

Author
A. K. M. Golam Sarwar

Abstract: Forty five accessions of dhaincha germplasms were collected from different parts of Bangladesh and characterized on the basis of morphological descriptors and biomass production ability. Thirty eight accessions were identified as Sesbania bispinosa, four as S. cannabina and two as unidentified Sesbania spp. One accession as S. rostrata was included for comparison. Both at seedling and maturity stages, wide and significant differences were observed among the accessions of different dhaincha germplasms for their biomass production capability and other morphological descriptors. At the seedling stage, total dry mass (TDM) production varied from 10.2 to 41.6g 30-plants–1. At the maturity stage, plant height, total number of branches and base diameter of dhaincha germplasms varied from 347.5–474.7cm, 10.4–23.7, and 1.9–4.9cm, respectively. The highest amount (4.10kg 10-plants–1) of above-ground TDM was produced in one accession of unidentified Sesbania sp. followed by S. rostrata and one accession of S. cannabina (3.85kg 10-plants–1), and the lowest TDM (0.9kg 10-plants–1) was measured in two accessions of S. bispinosa. It may be concluded that the biomass production capability of at least two accessions of local Sesbania germplasms were higher/comparable to that of exotic S. rostrata. It will be too early to make a conclusive remark based on only a few dhaincha germplasms. A detailed study with a large number of germplasms collected from whole Bangladesh is obviously needed to reach in a precise conclusion.

Review of catalytic supercritical water gasification for hydrogen production from biomass

Author
Y. Guo, S.Z. Wang, D.H. Xu, Y.M. Gong, H.H. Ma and X.Y. Tang

Renewable and Sustainable Energy Reviews, 2010, vol. 14, issue 1, pages 334-343
Abstract: Hydrogen is defined as an attractive energy carrier due to its potentially higher energy efficiency and low generation of pollutants, which can replace conventional fossil fuels in the future. The governments have invested huge funds and made great efforts on the research of hydrogen production. Among the various options, supercritical water gasification (SCWG) is a most promising method of hydrogen production from biomass. Supercritical water (SCW) has received a great deal of attention as a most suitable reaction medium for biomass gasification because it is safe, non-toxic, readily available, inexpensive and environmentally benign. However, high temperature and pressure are required to meet the minimum reaction condition. Therefore, the high operating cost has become the biggest obstacle to the development of this technology. To overcome this bottleneck, many researchers have carried out intensive research work on the catalytic supercritical water gasification (CSCWG). Based on the previous studies stated in the literature, the authors try to give an overview (but not an exhaustive review) on the recent investigations of CSCWG. Besides, the physicochemical properties of SCW and its contributions in subcritical and supercritical water reaction are also summarized.

Techno-economic analysis of ammonia production via integrated biomass gasification

Author
Jim Andersson and Joakim Lundgren
Applied Energy, 2014, vol. 130, issue C, pages 484-490

Abstract: Ammonia (NH3) can be produced by synthesis of nitrogen and hydrogen in the Haber–Bosch process, where the economic challenge is the hydrogen production. Currently, substantial amounts of greenhouse gases are emitted from the ammonia industry since the hydrogen production is almost exclusively based on fossil feedstocks. Hydrogen produced via gasification of lignocellulosic biomass is a more environmentally friendly alternative, but the economic performance is critical. The main objective of this work was to perform a techno-economic evaluation of ammonia production via integrated biomass gasification in an existing pulp and paper mill. The results were compared with a stand-alone production case to find potential technical and economic benefits deriving from the integration. The biomass gasifier and the subsequent NH3 production were modelled using the commercial software Aspen Plus. A process integration model based on Mixed Integer Linear Programming (MILP) was used to analyze the effects on the overall energy system of the pulp mill. Important modelling constraints were to maintain the pulp production and the steam balance of the mill. The results showed that the process economics and energy performance are favourable for the integrated case compared to stand-alone production. The main conclusion was however that a rather high NH3 selling price is required to make both production cases economically feasible.

A decision support system for planning biomass-based energy production

Author
Francesco Frombo, Riccardo Minciardi, Michela Robba and Roberto Sacile
Energy, 2009, vol. 34, issue 3, pages 362-369

Abstract: Environmental decision support systems (EDSS) are recognized as valuable tools for environmental planning and management. In this paper, a geographic information system (GIS)-based EDSS for the optimal planning of forest biomass use for energy production is presented. A user-friendly interface allows the creation of Scenarios and the running of the developed decision and environmental models. In particular, the optimization model regards decisions over a long-term period (e.g. years) and includes decision variables related to plant locations, conversion processes (pyrolisis, gasification, combustion), harvested biomass. Moreover, different energy products and different definitions of the harvesting and pre-treatment operations are taken into account. The correct management of the forest is considered through specific constraints, security factors, and procedures for parcel selection. The EDSS features and capabilities are described in detail, with specific reference to a case study. Discussion and further research are reported.

Renewable alternative fuels: Alcohol production from lignocellulosic biomass

Author
Stanley R. Bull
Renewable Energy, 1994, vol. 5, issue 5, pages 799-806

Abstract: Advances in renewable alternative biomass-based fuel technologies make their commercialization likely within a decade. Substituting fuels derived from biomass for fossil fuels can reduce dependence on petroleum use, improve air quality, mitigate global warming, and strengthen a weak farm economy. Implementation of the Clean Air Act Amendments of 1990 increased the oxygenate content in gasoline, providing greater market opportunities for alcohols—as direct blends and to produce ethers such as ETBE and MTBE. Alcohol production from lignocellulosic biomass is promising, leading to renewable, alternative transportation fuels that are projected to be competitive as pure fuels with fuels derived from petroleum at $20–$25/bbl ($0.13–$0.16/liter) within the next 5 to 10 years. However, the timeframe for deployment depends not only on the development of technologies, but also on the active involvement of appropriate industries. Industrial partnerships have been formed, and commercialization strategy is well under way; process development units at the pilot scale are both operating and under construction in the United States. Alliances between industry and the government include agreements to proceed with scale-up to engineering development units and eventually to commercial-scale plants.

Hydrogen production from biomass by catalytic gasification in hot compressed water

Author
Tomoaki Minowa and Seiichi Inoue
Renewable Energy, 1999, vol. 16, issue 1, pages 1114-1117

Abstract: Cellulose, a major component of woody biomass, was gasified to hydrogen rich gas using a reduced nickel catalyst in hot-compressed water of around 350 °C and 18 MPa. During the gasification, steam reforming and methanation can occur, and the methanation was prevented at subcritical condition. The reaction model and the catalyst are described.

Thermodynamic analysis of a biomass anaerobic gasification process for hydrogen production with sufficient CaO

Author
Jian Guan, Qinhui Wang, Xiaomin Li, Zhongyang Luo and Kefa Cen
Renewable Energy, 2007, vol. 32, issue 15, pages 2502-2515

Abstract: Based on CO2 acceptor gasification technology, a biomassanaerobic gasification technology for H2 production was proposed. Utilizing thermodynamic equilibrium calculation software FactSage 5.2, the rules of biomass/CaO/H2O and C/CaCO3/air reaction system involved in this H2 production technology were studied. The results show that the increase of CaO can obviously increase H2 mole fraction in C/H2O reaction products. When the mole ratio of CaO to carbon ([Ca]/[C]) is 1, H2 concentration may achieve the maximum value. The H2 amount obviously increases, and H2 mole fraction decreases slightly with increasing reaction pressure in a specific range. Higher reaction temperature obviously decreases the amount and mole fraction of H2. There are different maximum temperatures which are suitable for H2 production under various pressures. Increasing of the mole ratio of H2O to carbon of biomass ([H2O]/[C]) is helpful for H2 production. But the H2 mole fraction is reduced with the increasing of [H2O]/[C] when it exceeds 1.5. The calculations of linear sensitivity coefficient show that [H2O]/[C] has the greatest influence on H2 production efficiency, the influence of reaction pressure and temperature are also obvious. Compared with the coal gasification for H2 production, the excess of H2O in biomass anaerobic gasification system is relatively obvious. Lower reaction pressure is helpful for CaO regeneration in the C/CaCO3/air reaction system, and there are different minimum temperatures which CaO regeneration needs under various reaction pressures.

Author
Matej Polak (matej.polak@euke.sk) and Vladimír Kocak(vladimir.kocak@euke.sk)
Additional contact information

Abstract: Such as other sectors of industry, the agricultural sector has to find the way how to deal with new conditions within the world financial crisis. Other negatives which this sector has to deal are coming from the grant policy of EU, which creates different conditions in particular member countries. Financial crisis brought to agricultural industry new problems and challenges, which the private farms have to solve by the diversification of their business strategies. Some of the farms have already implemented new steps in their business plans by the growing of biomass for energetic purposes. Authors of the article are assessing the aim and scope of the action plan of biomass exploitation and its transformation to final energy in the farm PD Kapusany. This farm has close cooperation with the University of Economics Bratislava, Technical universities of Kosice and Zvolen. Result of this cooperation is the project of biomass exploitation in energetic sector. There was implemented new biogas station technology with the performance 180 kWh within the project.
