Formic acid synthesis and utilization for solar energy storage through solar?driven chloralkali process and fuel cells

The objective of this work is to propose an integrated system for formic acid synthesis via photovoltaic (PV) assisted-chloralkali process and clean power generation by the fuel cell. initial step develop flow diagrams apply heat integration techniques conserve energy in direct cell (DFAFC). proposed forms from gaseous H2 produced chloralkali unit captured CO2. electricity requirements both PV-assisted compression stages are supplied PV units. results imply that necessitates about 7.22 MW produce hydrogen at 25°C 1 bar with efficiency 84%. CO2 gases compressed 60 bars a total requirement 951 kW. In part, different scenarios developed determine minimum heating cooling maximum recovery. such were achieved hot cold utilities 599 kW 1884 kW, respectively.
