This paper investigates the feasibility of butanol as alternative fuel for transportation, starting from its production, from renewable hydrogen, to its utilization in SI (Spark Ignition) engines. In particular, the production pathway is based on the HT (high temperature) co-electrolysis by using the solid oxide technology and on the GtL (gas to liquid) plant via the intermediate product methanol. In order to evaluate the PtB (Power to Butanol) system performance and behavior, thermochemical and electrochemical models have been developed and validated by means of experimental data. Then, the behavior of a small, turbocharged spark-ignition engine, firing with gasolinebutanol blends (up to 40% butanol mass percentage), has been investigated and analyzed by means of experimental tests carried out at different engine operating points. Results show that butanol is a viable alternative to fossil fuels in the transportation sector.

Abstract
This paper investigates the feasibility of butanol as alternative fuel for transportation, starting from its production, from renewable hydrogen, to its utilization in SI (Spark Ignition) engines. In particular, the production pathway is based on the HT (high temperature) co-electrolysis by using the solid oxide technology and on the GtL (gas to liquid) plant via the intermediate product methanol. In order to evaluate the PtB (Power to Butanol) system performance and behavior, thermochemical and electrochemical models have been developed and validated by means of experimental data. Then, the behavior of a small, turbocharged spark-ignition engine, firing with gasolinebutanol blends (up to 40% butanol mass percentage), has been investigated and analyzed by means of experimental tests carried out at different engine operating points. Results show that butanol is a viable alternative to fossil fuels in the transportation sector.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
