Modern energy systems present important opportunities for efficiency improvement, particularly through integration of systems for multiple service extraction by redefining waste as an input to subsequent processes. This presentation introduces my research on the utilization of waste heat to produce hydrogen, as well as the use of hydrogen enrichment to improve efficiency and reduce emissions in internal combustion engines.

Addition of hydrogen to air-fuel mixtures in spark ignition engines has been shown to enable ultra-lean or high exhaust gas recirculation operation that increases efficiency and reduces emissions.

Thermochemical recuperation (TCR) processes utilize heat from the combustion exhaust stream to power catalytic reformation of the primary fuel in order to efficiently generate a hydrogen-rich gas for hydrogen enrichment. Under some conditions TCR will increase the net heating value of the processed fuel. My research has explored novel application of autothermal reformation techniques to TCR in order to utilize waste heat over a wide range of temperatures while providing a stable source of hydrogen.

Integration of TCR and hydrogen enrichment of spark ignition engines has the potential for 30% increases in efficiency and 95% reductions in engine-out NOx emissions. By focusing research on waste resource utilization technologies we can increase systems integration and achieve transformational increases in efficiency and sustainability across a wide range of applications.
