Renewable Hydrogen: Simultaneous Storage of Biorenewable Energy and Carbon Dioxide

Increasing amounts of low-cost and relatively pure carbon dioxide is available as a feedstock of nearly zero (or even negative) cost for conversion to fuels. On the other hand, the development of alternative sources for greener electricity generation (wind, hydro and photovoltaic) has a potential of making electrochemistry an inherently environmentally friendly, as electrons can replace more polluting conventional reducing agents. The aim of this proposal is to develop efficient electrocatalytic fuel production from carbon dioxide (residual emissions) and hydrogen (energy vector produced by intermittent renewable resources). Such fuel production can reduce the dependence on petrochemical resources through utilization of non-fossil fuel carbon as a building block.It is envisaged to use novel electrolytic systems capable to improve electrochemical reaction kinetics, assuring very high concentration of reagents in vicinity of electrodes, sufficient electrolytic strength and enhanced transport properties. In the last stage of this project, generated experimental data will be used for feasibility study to evaluate scalability and to estimate of the operational and investment costs.
