Building upon both strands of work, we propose to characterize business models of energy storage as the combination of an application of storage with the revenue stream earned from the operation and the market role of the investor.
profitability of energy storage. eagerly requests technologies providing flexibility. Energy storage can provide such flexibility and is attract ing increasing attention in terms of growing deployment and policy support. Profitability profitability of individual opportunities are contradicting. models for investment in energy storage.
Energy storages are an integral element of energy systems, especially in those with high shares of wind and solar power [1,2]. The intermittent nature of renewable energy sources can be balanced by the operation of flexibility options such as storages or demand side management.
Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).
A thermal energy storage with a PCM has been designed with the use of an electric heater for charging and water for discharge. The influence of the heat source temperature on the TES charging rate and its thermal capacity was investigated. The conducted numerical simulations confirmed the correctness of the designed TES.
