“…Retrofitting an existing thermal power plant with a heat pump and thermal stores was recently investigated in a study by Vinnemeier et al [34]. The concept is appealing because it results in a hybrid plant able to operate using either the original heat source (e.g.…”

“…Vinnemeier et al investigated this concept by modelling the performance of transcritical and supercritical (i.e. Brayton) heat pumps operating at temperatures compatible with steam power plants [34]. The authors found that the heat pumps were generally less susceptible to irreversibility when operating at higher temperatures (e.g.…”

“…Laughlin proposed a PTES concept based on closed-cycle Brayton cycle with cold hexane and hot molten solar salt storage [120]. Vinnemeier et al provided a characteristic diagram which allows to identify the most reasonable heat pump working fluid and process configuration referring to the boundaries of a specific storage concept [125]. McTigue investigated different PTES concepts with supercritical CO2 cycles with molten salt storage with and without concentrating solar heat input [126].…”

“…Indeed, fossil capacity is not directly replaced by renewable plants, resulting in an installed overcapacity corresponding to a rapid decline of fossil units operating hours [12]. Moreover, additional overcapacity and a further reduction of fossil-fuelled plants working hours encounter in the case of extensive exploitation of large-scale energy storage.…”
