Abstract
To reduce the economic and environmental costs of wastewater treatment, researchers are developing a novel treatment approach in which bacteria purify wastewater while producing hydrogen as a byproduct. To evaluate the feasibility of using this hydrogen for energy, a 1kW engine-generator was modified to combust hydrogen instead of gasoline. The engine was run at constant speeds of 5500, 5750, and 6000 RPM as its load increased, and intake and exhaust characteristics were measured. The engine emitted only water vapor and oxygen without harmful pollutants, but generated no more than .5 kW and ran at an equivalence ratio of no higher than .6 regardless of speed or hydrogen flowrate. Further characterization of hydrogen combustion in the engine is needed to improve power output.
