Abstract
This letter presents a design for a novel voltage controller (NVC) which can exhibit three different reactions using the integration of a vanadium redox battery (VRB) with solar energy, and uses only electrochemical potentials with optimal external bias voltage control to carry out hydrogen production and the conversion of carbon dioxide (CO2) into methane and methanol. This NVC is simply constructed by using dynamic switch and control strategies with a time-variant control system. In this design, the interval voltage bias solutions obtained by the proposed NVC exhibit better voltage ranges and good agreement with the practical scenarios, which will bring significant benefits to operation for continuous reduction of CO2 into value-added clean fuels using the integration of a VRB with solar energy or any other renewable energy resource for future applications.

Summary
Renewable energy generation increase and carbon dioxide (CO2 ) reduction targets have been included in energy policy in Taiwan. In photoelectrochemical (PEC) routes, photogenerated electrons are used to convert CO2 into synthetic fuels either directly at certain non-oxide semiconducting photoelectrodes or indirectly using a redox mediator [8]. These routes have been inadequate for performing on a commercial scale. This letter, we present a simple design for a novel voltage controller (NVC) using a standalone in this letter, we present a simple design for a novel voltage controller (NVC) using a standalone solar/BESS energy system to switch three different loop reactions in order to drive the reaction to solar/BESS energy system to switch three different loop reactions in order to drive the reaction to carry out hydrogen production and the conversion of carbon dioxide into methane and methanol.
