Current Research Status and Prospects of Electrode Boilers Under the Background of the “Dual Carbon” Goals

In the context of “dual carbon” goals, energy structures are rapidly shifting towards cleaner, low-carbon solutions. The clean and efficient electrode boiler, with its unique heat generation mechanism, is well aligned with this trend. This review begins by outlining the operating principles of electrode boilers, emphasizing their advantages in terms of energy efficiency and environmental sustainability. It then examines the current status of electrode boiler applications within the framework of the “dual carbon” objectives, addressing key challenges and technological barriers. The review concludes that electrode boilers hold significant potential for clean heating, grid peak-shaving, and the integration of renewable energy. However, research on electrode materials, boiler-based water treatment, electric field distribution within boilers, and corrosion issues remains insufficient. To address these gaps, this paper proposes several recommendations, including fostering cross-regional scientific collaboration, advancing the development of new electrode materials and coatings, and leveraging smart internet technologies to optimize electrode boiler performance and applications.
