This paper presents the concept of an electrode boiler working in cooperation with a thermal energy storage system, which constitutes a solution that can be integrated with heating systems to optimize the supply and demand for thermal energy.
High-voltage electrode boilers are closed pressurised vessels with water as a heat-receiving fluid on one side of their surfaces and high-voltage electrodes on the other side, where electrical energy is used as a power source instead of
Within this framework, the present study investigates potentials for application in buildings of the electrode boiler technology to minimize overloading events in the energy networks as well as to enhance demand-side management and energy flexibility.
High-voltage electrode boilers are not only an innovation in heating technology, but also a key fulcrum for the low-carbon transformation of the energy system. Its high efficiency, flexibility and safety are reshaping the energy utilization methods of industry and people''s livelihood.
Therefore, this paper proposes a control method for electrode boiler systems participating in rapid grid frequency response based on a fuzzy control strategy.
This review begins by outlining the operating principles of electrode boilers, emphasizing their advantages in terms of energy efficiency and environmental sustainability.
The electrode boiler enables converting the kinetic energy of ions that move in the fluid and collide against fluid molecules (from this the verbiage "ion friction") into heat
Then considering the influence of the frequently changing electrodes of the regenerative electric boiler on its working life, this paper introduces the optimization coefficient of electrodes, and the optimal operation strategy of hybrid energy storage system is put forward.
These zero-emission, high-voltage electrode boilers are used in diverse environments for applications such as centralized heating, power plants, nuclear stations, swing-load balancing, solar/wind energy consumption, and fuel boiler replacement.
High-voltage electrode boilers are closed pressurised vessels with water as a heat-receiving fluid on one side of their surfaces and high-voltage electrodes on the other side, where electrical energy is used as a power source instead of fossil fuel.
Electrode boilers feature high efficiency, no pollution, no emissions, and automatic control without the need of attendance, and can be used as an effective substitute or supplement for coal-fired, oil-fired and gas-fired boilers.

In the future, electrode boilers may integrate with novel thermal storage materials (e.g., phase-change materials and ceramic storage) to improve storage efficiency and thermal energy density. This will further enhance the electrode boiler’s capabilities in energy storage and heat recovery.
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.
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.
In terms of regulation, traditional sensors have limited accuracy, regulation systems exhibit slow response times, and algorithms are relatively outdated, with insufficient anti-interference capabilities, making them susceptible to external disturbances and unable to meet the demands of future electrode boiler developments.
The operation of nuclear power plants requires a significant supply of thermal energy. Compared to conventional coal-, oil-, and gas-fired boilers used in thermal power plants, electrode boilers offer several advantages, including lower investment costs, simpler piping systems, and easier installation.
