A low-temperature glide cycle for pumped thermal energy storage

Pcm-graphite Composites for High Temperature Thermal Energy Storage

Thermodynamic analysis of pumped thermal electricity storage

The increasing use of renewable energy technologies for electricity generation, many of which have an unpredictably intermittent nature, will inevitably lead to a greater need for electricity storage. Although there are many existing and emerging storage technologies, most have limitations in terms of geographical constraints, high capital cost or low cycle life, and few are of sufficient scale...

Modern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant

Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...

Cost and performance analysis of an integrated solar combined cycle with two tanks for indirect thermal energy storage

In this paper, the annual and economic performance of an integrated solar combined cycle (ISCC) with indirect energy storage tanks is investigated. The study includes four scenarios, in which the combined cycle performance was studied exclusively in the first scenario. In the second scenario, the integrated solar combined cycle (ISCC) was examined, and the use of supplementary firing instead of...

Energy efficiency in a building complex through seasonal storage of thermal energy in a confined aquifer

Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
