Novel artificial photosynthesis based carbon emission reduction technology with feasibility analysis of clean electricity generation.

The article focuses on a novel artificial photosynthesis (AP) based Carbon Capture and Utilization (CCU) technology designed to reduce carbon dioxide (CO2) emissions from electricity generation and produce clean power. Using a case study of a 56.1 MW wind power plant in Karnataka, India, the system captures CO2 emitted during the plant's life cycle via Direct Air Capture (DAC), synthesizes glucose through an AP-driven glucose reactor powered by wind energy, and then converts the glucose electrochemically into electricity via a Membrane based Direct Glucose Fuel Cell (M-DGFC). Results indicate that the system can capture 369 tonnes of CO2 and produce 252 tonnes of glucose within approximately 16 days under sufficient wind conditions, generating up to 37 kW/cm² of power density, thus creating a closed-loop power-to-power approach. Sensitivity analysis shows that wind speed directly affects glucose production and system efficiency, highlighting the integration of renewable energy with carbon capture for sustainable energy generation and emission mitigation.
