Carbon Clean Energy launched the first carbon dioxide electrochemical utilization system in Taiwan at 2024. The key advantage of this system lies in its ability to perform carbon dioxide utilization under ambient temperature and pressure. In addition, the hydrogen ions required for the electrochemical reaction are sourced directly from water, eliminating the need for externally supplied hydrogen gas. This design significantly enhances operational safety compared to conventional thermochemical processes, which typically involve high temperatures, high pressures, and flammable gases. Compared with thermochemical methods, electrochemical conversion also offers notable advantages in terms of equipment footprint. Taking Carbon Clean Energy’s compact system, E-Oak, as an example, the device measures less than 1.5 meters in length, width, and height—approximately the size of a household refrigerator—yet is capable of processing up to 5 tons of carbon dioxide annually. To further improve user convenience, the E-Oak system is equipped with a human–machine interface (HMI) and features fully automated electrolysis operations. Users can initiate and manage the entire conversion process with a single click, significantly reducing operational complexity and manpower requirements. In response to the growing demand for smart manufacturing and digital management, Carbon Clean Energy integrates 5G AIoT technology to synchronize operational data with a cloud-based cloud platform. This enables users to remotely monitor system performance in real time and to generate equipment operation reports for specific time periods with one click, thereby facilitating efficient data-driven decision-making and intelligent factory management. Beyond these features, the electrochemical stack within Carbon Clean Energy’s system incorporates proprietary patented technologies. Its modular design allows for easy expansion of the reaction area, enabling the system’s carbon reduction capacity to scale with minimal limitations. One of Carbon Clean Energy’s core strengths is its ability to customize the electrolysis stack area according to each client’s specific carbon reduction requirements. Furthermore, the system can be tailored to produce a range of electrochemical products, including green methanol, ethylene, carbon monoxide, and syngas. Clients may choose to directly reuse these products within their existing processes or further process and sell them, allowing companies to achieve carbon reduction while generating additional economic value. The operational workflow begins by connecting the system to on-site emission sources via pipelines, with flue gas used as a representative example. The flue gas is first directed into an upstream carbon capture unit, where carbon dioxide is separated and captured. The captured carbon dioxide is then compressed and fed into the E-Oak system for electrochemical conversion. Using carbon monoxide as an example product, the generated gas can be directly reused on-site or stored in gas cylinders. In the case of syngas production, the electrochemically generated carbon monoxide can be combined with green hydrogen to form syngas, which can partially substitute natural gas for combustion applications or be stored and sold as a value-added product. Carbon Clean Energy’s core technologies consist of mechanical system design, carbon dioxide electrolysis stacks, and advanced catalysts. Intellectual property protection has been established for each of these components, with patent applications currently underway, including one in the United States, two in China, two in Taiwan, and two PCT applications. Looking ahead, Carbon Clean Energy continues to develop next-generation catalysts to expand product options for clients, while simultaneously optimizing internal mechanical structures to deliver superior carbon reduction performance and an enhanced user experience.
