State of Art of Small Scale Biomass Gasification Power Systems: A Review of the Different Typologies
Manuela Sisinni

Energy Procedia, 2014

The security of supply and climate change issues and the linked recent growth of the local power generation by means of renewable energies technologies are providing real opportunities for the development of small scale biomass gasification systems. The present paper reports the state of art of the small scale gasification power plants. Initial attention has been given to the different biomass feedstock suitable for gasification, focusing on residues with low cost and low environmental impact. Then the two major typologies of gasifiers (fixed and fluidized bed) have been analyzed in terms of raw gas yield, composition and tar and particulate content. The different cold and hot raw gas conditioning systems, highlighting their compatibility with the different gasification system, are described. High efficiency examples of power production by means of internal combustion engine, micro gas turbine, Solid Oxide Fuel Cell or a mix of them, both as realized plants and process simulated ones, have been then reported. The paper provides an overview of the different power plants in terms of efficiency, reliability and cost.

Biomass gasification for rural electrification: prospects and challenges
Sangeeta Kohli

SESI J, 2003

In the development of rural India, employment generation is the most fundamental issue to be addressed, which, in today's context, is very closely connected to the power supply to villages. Decentralised power supply is being increasingly recognised as having much greater potential for supplying quality power to the remote areas as compared to the conventional centralised supply. Biomass gasification has emerged as a very promising technology for decentralised power generation and hence must be utilised for rural electrification to its full potential. In this paper, an effort has been made to draw attention to the suitability of this technology for power supply to villages and also to the challenges which must be addressed for effective use of the technology for this purpose. Many issues which need careful consideration, like resource and demand assessment, various aspects of plant management, economics and the government policies have been discussed. Many of these are pertaining to field situations and hence pose considerable challenge for effective handling. The paper is directed towards a wide class of readership -from those responsible for rural electrification including policy makers and implementers, who may need to know even the basics of the technology to those familiar with technology but with little or no experience in field implementation. It is hoped that such a paper will provide the concerned people with adequate exposure to the complexities associated with rural electrification using biomass gasification and hence help in its more effective implementation.

Green Energy Production:The Potential of Using Biomass Gasification
Edris Madadian

Journal of Green Engineering, 2014

Biomass gasification shows a great potential to displace fossil fuels. In this paper, the potential of bioenergy production from biomass feedstock has been investigated, focusing on gasification technology as an environmentally friendly alternative. The present research is principally focused on a down draft gasifier equipment kit (GEK) unit. Biomass encompasses a wide range of feedstocks such as agricultural residues, energy crops, forestry materials, food waste, municipal solid waste, grains and starch crops. An efficient gasification unit produces syngas with calorific value up to 20 MJ/kg. Syngas predominately consists of a mixture of hydrogen and carbon monoxide. This syngas can be used in a number of different processes including electricity generation, steam generation, transportation fuels, hydrogen production as well as chemical production, fertilizer manufacturing and consumer products. Results from our research highlight the potential of biomass gasification as a strong alternative for bioenergy production and a substitute for fossil fuels.

Promising Concepts for Biomass Conversion by Gasification in the Small and Large Power Range
Markus Bolhar-Nordenkampf

Biomass gasification offers the possibility to produce heat and power at a high efficiency. RENET Austria, a framework of scientists, industry and operators, has set up two gasification demonstration plants in Austria. One plant uses the FICFB (Fast Internal Circulating Fluidized Bed) gasification process, an innovative process to produce a high grade synthesis gas from solid fuels. The product gas is cleaned and combusted in a gas engine. The combined heat and power (CHP) plant has a fuel capacity of 8 MW and an electrical output of about 2 MW el with an electrical efficiency of about 25 %. The other plant uses a fixed bed gasifier to produce a low calorific gas, which is converted into heat and electricity in a gas engine too. This CHP-plant has a fuel capacity of 2 MW and an electrical output of about 500 kW el with an electrical efficiency of about 25 %.

Development of a Small Scale Biomass Gasifier and Testing of Various Feedstock
Bivek Baral

2017

Biomass is good source of energy in the field of renewable energy. Conventionally, use of biomass was made for simple firing purposes, for cooking and heating. However, more extensive use of biomass is seen in gasification process that may permit electrical utilities to obtain a portion of their fuel requirements from renewable energy sources. Gasification processes convert biomass into combustible gases. Biomass Gasification is a chemical process that converts biomass into useful convenient gaseous fuels or chemical feedstock. It has emerged as a promising technology to fulfill the increasing energy demands of the world, as well as to reduce significantly the volume of biomass waste generated in developing societies [1]. Maize cones, Maize steam, Pine needle and Cones, Hog Plum Seeds, Furniture Waste, Sugarcane Waste, etc. which has no food value can be used to produce syngas. Maize cones, Pine cones, Hog Plum seeds are compact and need no fuel modification while Pine Needles need ...

Energy production from biomass (Part 3): Gasification technologies
Peter McKendry

Bioresource technology, 2002

The conversion of biomass by gasification into a fuel suitable for use in a gas engine increases greatly the potential usefulness of biomass as a renewable resource. Gasification is a proven technology and can be operated either as a simple, low technology system based on a fixed-bed gasifier, or as a more sophisticated system using fluidized bed technology. The properties of the biomass feedstock and its preparation are key design parameters when selecting the gasifier system. Electricity generation using a gas engine operating on gas produced by the gasification of biomass is applicable equally to both the developed and the developing world.

A GLOBAL PERSPECTIVE ON BIOMASS GASIFICATION
Patrick Moriarty

Biomass is a unique renewable energy fuel in that unlike other renewables, it is naturally available as a solid fuel, but can be converted into liquid or gaseous fuels. The world in 2005 used around 48 EJ of biomass energy, nearly all of which was combusted at low thermal efficiency as fuelwood in developing countries. Around 4.6 EJ was used in modern biomass systems, either as liquid transport fuels or as a solid fuel for boilers in power stations or heating units. At present, very little is gasified. The future use of gasified biomass will increasingly depend on its ability to deliver higher greenhouse gas savings at lower costs than other ways of using bioenergy. Because of the high efficiencies possible for combined cycle gas turbines, the potential for gasification is considerable, but cost reductions and further technical progress are still needed. Its potential could be enhanced if gasification combined with carbon capture becomes feasible.

Small scale power generation unit using biomass gasification: the SUBe project
joão paulo azevedo

2019

This paper presents a research and development project aiming to demonstrate the technical feasibility of using forest biomass for power generation using small scale systems. For this purpose, an experimental setup, suitable to be used as a distributed generation unit, has been developed. Then, key developments of this project rely on the design and development of the biomass gasifier prototype as well as on the syngas cleanup system to fuel a conventional internal combustion engine for running the synchronous generator. Also, a suitable monitoring and control system will be developed to assure the safe operation of the whole system and to control the coordinated operation of the integrated subsystems. High level control functionalities will be implemented for performing load following when the power unit is operated in stand-alone or to adjust the output power following requests of the distribution system operator.info:eu-repo/semantics/publishedVersio

Sustainability aspects of biomass gasification systems for small power generation
CARLOS ALIRIO DIAZ GONZALEZ

Renewable and Sustainable Energy Reviews, 2020

A review of the aspects related to the sustainability of the biomass gasification and the use of syngas from biomass for small scale power generation is presented, taking as a frame of reference the sustainable development goals (SDG) of the UN. Initially, the most relevant aspects of the SDGs related to the energy transition and the energy trilemma are presented, as well as different considerations on the sustainability of bioenergy from biomass. The aspects related to the sustainability of the gasification processes are also presented, dividing them into different categories to find the most important restrictions for gasification processes under the framework of sustainability. Aspects such as the availability of land, the development of policies that promote the use of bioenergy, and the effects of syngas on the power and efficiency of combustion engines have been found to be the most relevant when reviewing the sustainability of biomass as a resource for small-scale power generation. It is found that the complexity of the relationship between bioenergy and sustainability requires the elaboration of detailed studies in the different aspects to find the most appropriate configurations and features to bring these energy solutions mostly to rural areas of developing countries.
