Hydroelectric pumped storage
Hydroelectric Pumped Storage (PHS) is the most widely utilised form of large-scale electrical energy storage (EES). The energy is stored as the potential energy of water raised against gravity. Water is pumped from a lower reservoir (1) to a higher reservoir (2), using the energy provided by the pumping unit (3), storing it as potential energy in the water. Figure 1 is a simple scheme of a PHS ...
متن کاملThermodynamic 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...
متن کاملThermodynamic efficiency of pumped heat electricity storage.
Pumped heat electricity storage (PHES) has been recently suggested as a potential solution to the large-scale energy storage problem. PHES requires neither underground caverns as compressed air energy storage (CAES) nor kilometer-sized water reservoirs like pumped hydrostorage and can therefore be constructed anywhere in the world. However, since no large PHES system exists yet, and theoretical...
متن کاملOperating Experience with Raydac
THE RA YDAC acceptance tests were run from June 4 to July 19, 1952, in five sessions of 3 days each. The tests were divided into three phases. Phase 1 consisted of programmed test routines which caused each unit of the computer to go through its various combinations of operations. This included tests of the terminal equipment, central control, and internal memory; the arithmetic unit; and the e...
متن کاملHigh-power diode-pumped fiber laser operating at 3 μm.
A high-power diode-cladding-pumped Ho³⁺-doped fluoride glass fiber laser operating in cascade mode is demonstrated. The ⁵I₆→⁵I₇ and ⁵I₇→⁵I₈ laser transitions produced 0.77 W at a measured slope efficiency of 12.4% and 0.24 W at a measured slope efficiency of 5.2%, respectively. Using a long fiber length, which forced a large threshold for the ⁵I₇→⁵I₈ transition, a wavelength of 3.002 μm was mea...
