Coal to electricity heating and energy storage

Can heat storage transform coal-fired power plants?

This article provides a review of the research on the flexibility transformation of coal-fired power plants based on heat storage technology, mainly including medium to low-temperature heat storage based on hot water tanks and high-temperature heat storage based on molten salt.

Can thermal energy storage improve the flexibility of coal-fired power plants?

At present, large-scale energy storage technology is not yet mature. Improving the flexibility of coal-fired power plants to suppress the instability of renewable energy generation is a feasible path. Thermal energy storage is a feasible technology to improve the flexibility of coal-fired power plants.

How does coal-to-electricity work?

On the one hand, “Coal-to-Electricity” can effectively reduce the burning of loose coal, increase the utilization of coal by power generation, improve the efficiency of coal utilization, and reduce pollutant emissions. 1 ton of loose coal combustion emissions are equivalent to 5–10 tons of power plants burning coal pollutants.

What is coal-to-electricity?

On the other hand, “Coal-to-Electricity” can promote the elimination of clean energy, and can use the abandoned wind to abandon the photoelectric amount to achieve clean heating, instead of burning coal for heating, reducing the total amount of coal consumption.

How does a coal stove work?

Residents separately purchase the bulk coal and transport them to the residences for storage. The coal is directly burned in the primitive coal stoves, and the heat warms the surrounding air by radiation, which can only heat the nearby area, with a small range and low comfort.

How does China's coal to electricity policy affect the power system?

Compared to air pollution, the Coal to Electricity (CtE) policy's impacts on the power system are less discussed. As China transitions to carbon neutrality, unstable wind, and photovoltaic (PV) units exacerbate power dispatching challenges amid increased heating loads.
