University of Minnesota, Morris and partners develop diesel genset fueled by biomass
24 June 2012
The University of Minnesota, Morris, in partnership with Cummins Power Generation and the University of Minnesota Center for Diesel Research, has developed a transportable diesel engine generator (genset) that can be powered by biomass, called the PowerTrainer. The University is demonstrating the unit on 28 June.
Completely housed in a standard 20-foot shipping container, the unit was built by All Power Labs in Berkeley, California. Funding for the project was provided by the National Energy Technology Laboratory.
The unit comprises a gasifier, gas cleanup, fuel hopper, fuel handling system, diesel genset, and control system. The project focuses on the integration of a biomass gasifier with a commercially available diesel powered genset and aims to distinguish the characteristics of producer gas that may be useful or harmful to the system. The anticipated outcome of the research is a new transportable generation platform capable of displacing fossil fuel use in diesel generators.
The genset, when run on diesel, can generate up to 100 kW of electricity. A target for the genset when run on producer gas is 80 kW. One key benefit of this technology will be a 90% or greater potential decrease in greenhouse gas emissions by substituting renewable fuel sources for diesel fuel. The operating efficiency of this prototype system will be compared with the efficiency of the biomass gasification combined heat and power plant already in service on the Morris campus.
The PowerTainer has several potential applications, the University said. On farms, the shaft power can be used to run farm machinery, and the producer gas can be used to fuel grain dryers in addition to powering the generator. In disaster areas, wood and debris can be used to fuel the generator and provide electricity or mechanical power. Other potential applications include military and small industry use.
