Prospective CO2 emissions from energy supplying systems

Conclusions: A quantitative study based on life cycle assessment has compared the CO2-eq.per kilowatt hour emissions coming from supplying an electrochemical reactor by conventional grid and by photovoltaic solar modules under Spanish frame conditions and stated that the novel process photovoltaic solar electrochemical oxidation would be a preferred environmental option due to the lower CO2-eq.per kilowatt hour emissions under present and future scenarios.
