It is the perennial problem associated with renewable enery: how can the sun be used to provide energy even when it is not shining?
With heat storage installed, the production of electricity and heat can be uncoupled for a period of time.
A microgrid consists of a localized, nominally self-sufficient group of consumers and producers.
When it comes to Direct Current (DC), confusion reigns about where to draw the line around the concept of a microgrid.
Two complementary technologies - district cooling and thermal energy storage - are being increasingly used, not only in their traditional US market but also in other markets around the world.
Korea's Incheon Container Terminal (ICT) has purchased a REGEN energy storage flywheel unit from US-based VYCON to maximize fuel savings on its gantry cranes. Fuel savings are achieved through the REGEN's ability to harness the power generated during the lifting operations and use it during the crane's peak lifting cycles.
The key to developing a smarter power grid is to standardize and integrate two systems: the power and energy delivery system and the information system that controls it.
The technology holds vast promise, but the hype has far outstripped the reality. i
Finning International has won a $7m contract to build a power plant to supply electricity to Barrick Gold Corp.'s gold project in Argentina.
The 'electronic age' demands high quality power, free from surges and harmonics. Supercapacitors can meet these needs, and have advantages over batteries and other power quality devices.
