Propose a model to assess economic feasibility for decoupled energy storage. Revenues from both energy markets and ancillary service markets are considered. Optimal sizes for the charging, storing and discharging unit are obtained. Profitability can be improved by increasing waste heat or system scale.
According to , a decoupled energy storage system means the storage medium is stored independently and can be physically separated from the charging and discharging units. In a decoupled energy storage system, each unit (charging, storing and discharging) can be sized independently, examples include PHES and CAES.
By using a genetic algorithm, our model provides the optimal design of the size/capacity of different components and assesses the economic feasibility of the liquid air plant. The profitability of a liquid air energy storage plant can be improved by either introducing waste heat into the system or increasing system scale.
According to , and many others, only two technologies are considered mature for grid-scale energy storage: Pumped Hydroelectric Energy Storage (PHES) and Compressed Air Energy Storage (CAES), which are both examples of decoupled energy storage technologies.
On 1st August 2017, Highview Power Storage was awarded a £1.5 million grant from Innovate UK to add super-capacitors and flywheel technology to the existing 5 MW/15 MWh demonstration plant.
