Biomass Gasification getting ready for t
Small and mid-range capacity thermo chemical biomass gasification for power production is showing promising new potential as part of the energy mix for decentralized energy production from renewable energy sources. Still, a few developmental hurdles remain before the technology can finally break through and become ecologically and economically feasible, particularly in regards to waste emissions and energy efficiency, as well as general social awareness. The renewable energy awareness organization FEE e.V. has established a workgroup dealing with biomass and is collaborating with REECO GmbH to present the 5th International User Conference for Biomass Gasification as part of the CEP® CLEAN ENERGY & PASSIVEHOUSE on February 11th, 2011.
The demand for wood gasification units for the combined production of electricity and regenerative heat remains strong, particularly for small capacity units. At present, facilities with a production capacity of 5 MWel are poised to enter the market rather successfully. End users have shown an increasing interest in units with under 150 MWel.
One of the challenges for developers is perfecting the processing technology that has shown the most promise and create solutions that will lead to long-term success. These include increasing the automation, reducing heat loss and improving the energy conversion efficiency which is currently at around 25 percent.
The emission of organic waste into the air presents a special challenge. “The production of emissions must be examined more closely,” according to Christian Hischmeier from FEE. “The focus here should be on benzene as a leading indicator. Gasification with less benzene producing less tar is achievable with modern technology.” The reduction in both the toxicity and amount of gasification waste is another area where work is being done.
Solution oriented research and development in collaboration with manufacturers must be improved, in order to help bring thermo chemical biomass gasification up to a marketable level. This also goes for new plans to look to regenerative methane in the gas network at its key potential as a means of energy storage in a system of renewable energies. This technology, according to FEE, should be cemented in the energy concept of the German government as well as in energy research plan and should play a key part in the 2012 revision of the renewable energies law. Collaborating developers, manufacturers, planners and operators into a well-networked business sector would help immensely in reaching this goal.
The 5th International User Conference for Biomass Gasification on February 11th, 2011 will offer investors and potential users a current overview of the state of technological development of marketable gasification systems – all as part of the CEP® CLEAN ENERGY & PASSIVEHOUSE in the New Trade Fair Centre Stuttgart. The conference will discuss national and international developments in the area of market-ready small and mid-sized biomass gasification systems for cogeneration. The event aims to assist the introduction of gasification systems on the wider market.
The CEP® 2011 will for the first time offer an entire exhibition hall dedicated to the topic of bioenergy. In particular wood energy, forestry technology, cogeneration and biogas will be the central topics of this exhibition area. The trade forum on bioenergy dealing with the bioenergy village sponsored by the Baden-Württemberg Ministry of Food and Rural Affairs as well as the Economic Ministry completes the program.
