GRE DFB multi-fuel gasification
The GRE DFB gasification system is the world’s first functioning FICFB (Fast Internally Circulating Fluidized Bed) plant. The core of the plant is formed by the two inter-connected fluidized bed systems of the fluidized bed steam gasifier (reactor).
In the gasification zone the cut-down biomass is whirled up and gasified in anaerobic conditions at approx. 850°C in the shortest time possible by introducing steam. The bed material (olivine sand) has the function of a heat transfer medium and provides a stable temperature in the reactor.
In the next step the resultant product gas is purified and cooled. The heat emitted during cooling is used for the generation of district heat. Subsequently, the gas is filtered, and tar scrubbed with bio-diesel. In this specialized process all resulting residual materials are recycled.
In the gas purification neither solid waste nor waste water arises, and the product gas is completely free from nitrogen. Fluidized bed steam gasifiers work extraordinarily reliably and regularly (7,000-8,000 operating hours per annum) and are considered state-of-the-art (Best Available Technology).
A downstream engine optimized for gas operation can produce electric power and heat from the product gas (combined heat and power, CHP), with the overall efficiency being higher than 85%. Alternatively, a methanization plant also allows the generation of bio synthetic natural gas (BioSNG) from product gas in certified quality. The product gas consist of up to 40% of hydrogen, which can be extracted; in Fischer-Tropsch-Synthesis high-grade fuels can be synthetisized from the product gas.
The GRE Multi-Fuel Plant, the logical advancement of the plant developed in Güssing and in use there since 2002, reliably provides energy with system relevance – i.e., a minimum of 7.000 hours per annum – and, in addition to the feedstock wood, also allows waste materials rich in hydrocarbon, dried sewage sludge, and the like, to be used as feedstock for gas generation.
The energetic exploitation of waste otherwise unusable as a material is increasingly becoming of interest to communities, as waste management presents an enormous logistic and financial burden which will still increase in the future. In gas generation the toxic potential of the waste is eliminated without causing harm to the environment.
What is used here, is fractions of high caloric value from the mechanical-biological processing of domestic waste, domestic-waste-like industrial waste, and the like. The construction of the GRE Hofbauer Reactor is more than 50% cheaper than that of comparable waste combustion plants.
GRE realized this progress together with German engineering consultancy Consulectra (RWTÜV group), and the scientific support by VUT (Vienna University of Technology, Prof. Hermann Hofbauer).
The planning of the Multi-Fuel Plant has been completed, documented and certified, the application for a patent will be filed shortly. Blueprints for putting it into practice are ready. This makes Güssing Renewable Energy the world´s only enterprise which is in a position to offer this technology on a realistic basis. Owing to the advanced engineering applied, GRE has a technological lead of at least 10-15 years.

We continued looking for alternative feedstock to be utilized in the GRE DFB gasifier for the production of energy and met Mr. Pinter who manages various short-rotation plantations and tells us his experiences with the crops.
tech flash gasification animation -> polygeneration
This animation of the GRE DFB gasification system will show you how we produce a multitude of energy-products such as electricity, heat, natural gas and liquid fuels from carbonic residues. We call this process "polygeneration". Instead of combusting the waste material, which create additional CO2 in the atmosphere, our gasification technology is 100% CO2-neutral.
tech flash liquid fuels from biomass through Fischer-Tropsch synthesisIn this video we show you how we convert biomass to liquid fuels. Through Fischer Tropsch synthesis, the cleaned syngas from GRE DFB gasification systems can be turned into waxes for further refining to liquid fuels. With the side-by-side comparison, you will see the advantages of biomass derived fuels compared to fossil fuels.
Gasification vs. Incineration
In this video the two applications gasification and incineration are compared, whereas the advantages of gasification are clearly visualized.

ACC Limited is India's largest cement producer and is interested to cut down their CO2 emissions by generating energy for their manufacturing from renewable resources.
energy crisis - old news for the salt industry
A documentary about the energy-crisis of the salt industry over the last centuries. The efficient utilization of biomass was an important cornerstone to accelerate the development of the salt industry in the municipality of Steinbach by the Attersee. The first wood scarcity in the 12th century made the locals inventive.
Today, the salt industry by the Attersee imports fossil fuels from abroad. With the help of a GRE DFB gasifier, local wood resources could be utilized for decentralized and sustainable energy production.
License agreement with Edison Power Co. Ltd. from Japan signed
Güssing Renewable Energy GmbH and Edison Power Co. Ltd. sign a license agreement for the exclusive rights to the GRE DFB gasification technology in Japan
Güssing Renewable Energy GmbH proudly announces the signing of a license agreement with Edison Power Co. Ltd. for the exclusive rights to manufacture, build and operate the GRE DFB gasification technology in Japan. The GRE DFB gasification technology, originally developed at the Vienna University of Technology, under the lead of Prof. Hermann Hofbauer, is the first functioning FICFB (Fast Internally Circulating Fluidised Bed) plant worldwide. The first plant of this technology was commissioned in Güssing, Austria in 2002 and has since achieved over 80,000 operating hours.
The partnership with Edison Power Co. Ltd. foresees the construction of the first demonstration plant in 2014-2015. This first plant will serve as know-how transfer and to showcase the ability of this technology to potential public and private customers in Japan. The first commercial plant, with 1MW electric output, is scheduled in the Ibaragi prefecture in 2015.
Prime Minister Abe’s policy to activate Japan’s rural communities creates large potential for sustainable and renewable energy solutions. The GRE FICFB Gasification Technology is a ready-to-use technology for the utilization of carbonic waste-streams for decentralized and CO2-neutral energy production.
Mr. Peter Panholzer, CEO of Güssing Renewable Energy GmbH: “We are happy and confident to step into a partnership with Edison Power in Japan, to provide our Carbon Recycling© technology and our community development to the Japanese communities."
