BIOMASS GASIFIER IN INTERNALLY RECIRCULATING BUBBLING FLUIDIZED BED (ICBFB) FOR PRODUCTION OF GASEOUS ENERGY CARRIERS
Technology Readiness Level (TRL)
6
Innovations and Benefits
This technology allows to valorize energetically residual distributed biomass with efficiency higher than the conventional combustion technology. Thanks to the use of a steam/oxygen mixture as a gasifying agent with PCI of 10-12 MJ/Nm3, with mean composition for the main fuel gases of: 30-33 %v H2, 28-32 %v CO, 9-11 %v CH4 and an energy conversion efficiency higher than 70% can be obtained. The use of oxygen allows to significantly intensify the process, with consequent benefits in terms of reduction of plant equipment, investment costs and environmental impact. ICBFB gasification can effectively support the diffusion and consolidation of the small-medium-size CHP energy distributed production model through conventional systems such as internal combustion engines (ICE), or through higher conversion efficiency systems, such as gas turbines (GT) and fuel cells (FC). The produced gas can be used for producing secondary energy carriers, gaseous and liquid (e.g. H2, SNG, FT fuels, MeOH, DME), green-chemicals.
Use
This technology can find application in:
- companies producing renewable energy with lower GHG emissions;
- companies/districts having wood wastes available (working, farming, agroindustrial wastes) and interested in their energy valorization;
- companies producing chemicals from syngas for replacing fuel sources with renewables.
Applications and ongoing Activities
Realization of high-efficiency distributed industrial facilities of approximately 1 MWe power.
Several nationally-funded projects are underway on biomass gasification as well as consulting services to industrial partners. Therefore, significant expertise is available to provide support for the set-up and management of industrial facilities. Recently completed (2016) the EU project UNIfHY (Grant agreement No. 299732) aimed at producing FC-grade hydrogen to be used in the electric transport sector. ENEA is patent co-owner of the ICBFB gasifier, with the University of L’Aquila (2008IT-URM0022 14/02/2008, patent no. RM2008U000022 29-07-2011).
