Carbon capture is a critical process for separating, purifying, and recovering CO₂ from industrial emissions or the atmosphere, serving as the entry point between carbon emissions and resource utilization. In e-Fuels and carbon cycle systems, CO₂ is not only an emission but also a valuable feedstock for further conversion.

Depending on the application, CO₂ can be sourced from industrial off-gases (such as chemical, steel, and cement industries) or from direct air capture (DAC). These sources differ significantly in concentration, impurity composition, and fluctuation characteristics, placing different requirements on capture technologies, purification processes, and system stability.

In engineering applications, carbon capture is not merely a separation process but also involves gas pretreatment, impurity removal, concentration enhancement, and pressure and flow regulation. Its core function is to provide a stable, continuous, and controllable CO₂ supply for downstream conversion. System performance depends not only on capture efficiency but also on energy consumption, operational stability, and integration with subsequent processes.

EPC Energy focuses on the “power–hydrogen–carbon” coupling pathway, delivering engineered carbon capture systems through integrated design and process optimization. By enabling advanced gas treatment, CO₂ is transformed from an emission source into a usable feedstock. Through coordinated design with hydrogen production and CO₂ conversion systems, stable coupling between subsystems is achieved, supporting the practical deployment of carbon utilization technologies.

CO₂ conversion is a key process that transforms captured carbon dioxide into usable intermediates or fuel molecules, serving as a core pathway connecting carbon resources with green fuel systems. Through electrochemical (CO₂RR) or thermocatalytic processes, CO₂ can be converted into carbon monoxide (CO) or syngas, which can be further used for the synthesis of methanol, methane, and liquid fuels.

In engineering applications, CO₂ conversion emphasizes process controllability and system integration. By converting CO₂ into intermediates and coupling with downstream synthesis processes, a more stable and scalable fuel production pathway can be achieved.

EPC Energy focuses on CO₂ conversion pathways through coordinated optimization of electrolysis systems and reactor design, enabling stable conversion of CO₂ into usable intermediates and efficient integration with downstream fuel synthesis systems.
