Energy storage for clean heating

Why is heat storage important?

Heat storage has been proven to be an effective way to fill the gap between energy supply and demand in building heating, it has demonstrated tremendous potential in advancing the utilization of renewable energy for clean heating.

What is seasonal thermal energy storage (STES)?

Seasonal thermal energy storage (STES) harvests and stores sustainable heat sources, such as solar thermal energy and waste heat, in summer and uses them in winter for heating purposes, facilitating the replacement of fossil fuel-based heat supply and coordinating the seasonal mismatch between heat supply and demand .

What is integrated energy storage for distributed heating?

Besides, integrated energy storage for distributed heating is also a research highlight for clean heating as it helps balance the supply load of the power grid, reduce the peak–valley gap, increase production efficiency and cut operating costs of distributed heating.

Why is long-term storage important for sustainable heat use?

The optimal usage of sustainable heat requires long-term storage to account for seasonal fluctuations in supply and demand.

What is sensible heat storage?

Sensible heat storage is so far the most widely used way of heat storage in building heating. 13 Water heat storage is the oldest and most technically mature way of sensible heat storage with high specific heat, low costs and good heat transfer and fluidity.

Why is energy storage important?

Energy storage can largely increase the reliability of the energy supply system to consume renewable energy, offset the randomness, fluctuation and discontinuity of renewable energy and facilitate the use of renewable energy in the building sector.
