Energy piles offer a promising and eco-friendly technique to heat or cool buildings. Energy piles can be exploited as ground heat exchangers of a ground source heat pump system. In such application, the energy pile and its surrounding soil are subjected to temperature changes that could significantly affect the pile–soil interaction behaviour.
behaviours of energy piles is not available yet. In most cases, the design of energy piles has been based on empirical considerations (Boënnec, 2009). In order to be on the safe side, the safety factors could lead to error in predicting the energy pile behaviour. Several experimental studies have proven that subjecting soils to heating/
The challenges of large-scale energy storage application in power systems are presented from the aspect of technical and economic considerations. Meanwhile the development prospect of global energy storage market is forecasted, and application prospect of energy storage is analyzed.
Energy piles are a type of green foundations that can reduce the amount of energy consumed for space heating and cooling by up to 75%. It is inevitable that the operation of energy piles imposes heating and cooling cycles not only the pile but also the surrounding soil.
The heat exchange capacity of the energy pile depends on the thermal resistivity of the pile and the surrounding soils. The consequently, their thermal behaviour could be different. The pile Lennon et al., 2009; Wood et al., 2010) is not in good agreement with the theoretically calculated value.
Even if the energy storage has many prospective markets, high cost, insufficient subsidy policy, indeterminate price mechanism and business model are still the key challenges.
It is suitable for high power requirement. But there are many disadvantages such as high cost, low energy density and complex maintenance . The comparative analysis of electromagnetic energy storage technology is shown in Table 3.
