Summary of Research Results

Analysis of a Whole Adiabatic Compressed Air Energy Storage Systems

Compressed Air Energy Storage (CAES) is considered as one of the cheapest Energy Storage (ES) technologies in terms of capital cost ($/kWh) and maintenance cost ($/kW-year). CAES works in the process as: the ambient air is compressed via compressors into one or more storage reservoir(s) during the periods of low electricity demand (off-peak) and the energy is stored in the form of high pressure compressed air; during the periods of high electricity demand (on-peak), the stored compressed air is released, heated by a heat source from the combustion of fossil fuels or other methods, and then the energy stored in compressed air is captured by turbines/expanders to generate electricity. The major concern in deployment of CAES is its relatively low cycle efficiency compared with other ES technologies. (more…)

Feasibility study of Thermal Energy Storage integration with power plant operation

Load balance in the power grid is managed mainly through fossil fuel peaking generation plants that respond passively to the load changes. With increased deployment of intermittent renewable power generation, conventional power plants play more important role in frequency control, as they are considered as flexible power generation units. This requires power plants working more flexibly, responding faster and more frequent (start-ups/shut-downs) for maintaining the power network stability.  IMAGES project explore a new technology which will address the challenges. The project conducted feasibility study for suitable way of integrating Thermal Energy Storage (TES) to the power plant operation (steam-water loop) and investigate how the plant dynamics respond to the cycle of energy storage.
