Superconducting magnetic energy storage technology and flywheel energy storage technology
Superconducting magnetic energy storage technology In the 1970s, Superconducting Magnetic Energy Storage (SMES) began to be used in power systems. Superconducting magnetic energy storage uses the characteristic that the resistance of a superconductor approaches zero when the temperature is close to absolute zero to store electrical energy in the superconducting coil without loss. The core […]

The characteristics of fuel cell and the microturbine
Features of fuel cell The distributed fuel cell demonstration power station uses natural gas as fuel. The natural gas is first converted into hydrogen, which is then sent to the fuel cell generator set to produce electricity and hot water. In principle, as long as the fuel cell continuously inputs reactants and discharges reaction products, […]

The working principle of the fuel cell
A fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy. In 1839, British scientist W.R.Grove discovered and verified the phenomenon of fuel cells in the laboratory. However, due to the failure of the research on the dynamics of generators and electrode processes to keep […]

Composition of solar thermal power generation system
Generally speaking, solar thermal power generation technology refers to solar steam thermal power generation technology. It uses a large-scale array of parabolic or dish-shaped mirrors to collect solar thermal energy, provides steam through a heat exchange device, and combines the technology of traditional steam turbine generators to achieve the purpose of generating electricity. It avoids […]
