Electrochemical production of syngas from CO2 at pressures up to 30 bar in elec...
Messias, Sofia; Sousa, Miguel M.; Ponte, Manuel Nunes; Rangel, C. M.; Pardal, T.; Machado, AnaABSTRACT: Electrochemical CO2 reduction in a reactor that can operate up to 100 bar and 80 degrees C, with a configuration similar to that of an alkaline electrolyser, for hydrogen production suitable to be used industrially is reported for the first time. The effect of pressure on the co-electrolysis of CO2 and water was studied. The successful scale-up from a previously reported batch process to electrodes of...
Electrochemical CO2 reduction at room temperature and mild pressures
Messias, Sofia; Sousa, Miguel M.; Ponte, Manuel Nunes; Rangel, C. M.; Pardal, T.; Machado, AnaABSTRACT: Carbon capture and utilization technologies (CCU) and electrolytic hydrogen production are closely interconnected technologies and necessary for a sustainable energy system. This work describes the development of a process for room temperature co-electrolysis of CO2 and water to produce syngas, at mild pressures. The influence of several parameters in the performance of the process is reported.

Pressurized electrochemical process for syngas production [Resumo]
Messias, Sofia; Sousa, Miguel M.; Rangel, C. M.; Pardal, T.; Ponte, Manuel Nunes; Machado, AnaABSTRACT: Carbon Capture and Utilisation (CCU) comprise technologies that capture carbon dioxide and convert it into chemical products, such as fuels, chemicals and building materials that can replace the same products derived from fossil resources. These technologies can thus contribute to reach the ambitious 2030 targets set by the European Union for decarbonisation of the economy of 40% CO2 reduction, introd...
