The shale gas revolution in the United States in recent years has resulted in an oversupply of methane and ethane, the major components of natural gas and natural gas liquids, respectively, and this trend will continue for the foreseeable future. Due largely to these cheap resources, the chemical industry has moved manufacturing plants back to the United States, creating thousands of jobs, while enjoying healthy margins compared to international rivals that typically use more expensive oil-based naphtha as feedstock. However, the ethylene production from ethane or naphtha is energy intensive and represents the single most energy consuming process in the chemical industry. To fully exploit the potential of ethane as a feedstock, low-thermal-budget and low-carbon footprint processes are required. We demonstrated that co-production of ethylene and hydrogen through an electrochemical deprotonation process at intermediate temperatures with significant reduction in process energy and CO2 emission, compared to the commercial ethane steam cracking process. If the heating value of produced hydrogen is taken into account, the electrochemical deprotonation process actually has a net gain in processing energy.
