ESolar
eSolar is a privately held company that develops concentrating solar power (CSP) plant technology. The company was founded by the Pasadena-based business incubator Idealab in 2007 as a developer of CSP plant technology. The company aims to develop a low cost alternative to fossil fuels through a combination of small heliostats, modular architecture, and a high-precision sun-tracking system. In October 2017, an article in GreenTech Media suggested that eSolar ceased business in late 2016. Technology Heliostat design eSolar has designed heliostats that are smaller than the industry norm, allowing for pre-fabrication, mass-manufacturing, and easy installation, thereby reducing production and installation costs. eSolar announced a new heliostat design, referred to as SCS5, during the 2013 SolarPACES Conference in Las Vegas, Nevada. SCS5 offers a more simplified design and enhanced reliability to reduce total installed solar collector system cost by more than a third. Sun-tracki ...

Sierra SunTower
Sierra SunTower was a 5 MW commercial concentrating solar power (CSP) plant built and operated by eSolar. The plant is located in Lancaster, California. As of mid-September, 2022, the two towers that were the center of the facility are no longer standing. However the rest of the plant is still present. Project overview The Sierra SunTower facility was based on power tower CSP technology. The plant featured an array of heliostats which reflected solar radiation to a tower-mounted thermal receiver. The concentrated solar energy boiled water in the receiver to produce steam. The steam was piped to a turbine generator which converted the energy to electricity. The steam coming out of the turbine was condensed and pressurized back into the receiver. In the summer of 2009, eSolar unveiled the 5 MW Sierra SunTower plant, a commercial facility in Lancaster, California, to demonstrate the efficacy of this CSP technology. Sierra SunTower was connected to the Southern California Edison ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern California Edison
Southern California Edison (or SCE Corp), the largest subsidiary of Edison International, is the primary electricity supply company for much of Southern California. It provides 15 million people with electricity across a service territory of approximately 50,000 square miles. However, the Los Angeles Department of Water and Power, San Diego Gas & Electric (SDG&E), Imperial Irrigation District, and some smaller municipal utilities serve substantial portions of the southern California territory. The northern part of the state is generally served by the Pacific Gas & Electric Company of San Francisco. Other investor-owned utilities (IOUs) in California include SDG&E, PacifiCorp, Bear Valley Electric, and Liberty Utilities. Southern California Edison (SCE) still owns all of its electrical transmission facilities and equipment, but the deregulation of California's electricity market in the late 1990s forced the company to sell many of its power plants, though some were probabl ...

Ferrostaal is a German-owned industrial services company. It has 4,400 employees and an annual turnover of around 1.6 billion euros (2008), and has a market presence in around 40 countries. The company's activities are focused in two areas: Projects (Petrochemicals, Industrial Plants, Solar Energy and Power) and Services (Equipment, Piping, Automotive). In 2009, the International Petroleum Investment Company (IPIC) of Abu Dhabi took over 70% of the shares of Ferrostaal AG from MAN AG, Munich. Due to the acquisition of the majority shares, the company entered the commercial register as Ferrostaal, signifying its separation from the MAN Group. History Ferrostaal was founded in The Hague, Netherlands, in 1920. The steel trading company was bought by Gutehoffnungshütte Aktienverein (GHH) in 1926. Over time Ferrostaal expanded into more countries, and had a presence in the international steel trade from the 1950s onwards. During the 1960s the company started building industrial plant ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

The Solar Project
The SOLAR Project consists of the Solar One, Solar Two and Solar Tres solar thermal power plants based in the Mojave Desert, United States and Andalucía, Spain. The US Department of Energy (DOE) and a consortium of US utilities built the country's first two large-scale, demonstration solar power towers in the desert near Barstow, California. Solar One/Solar Two have been scrapped since 2009. Solar Tres (later renamed Gemasolar), the first commercial plant of the project, was opened in Spain in 2011. Solar One Solar One was a pilot solar-thermal project built in the Mojave Desert just east of Barstow, CA, USA. It was the first test of a large-scale thermal solar power tower plant. Solar One was designed by the Department of Energy (DOE) (led by Sandia National Laboratories in Livermore, California), Southern California Edison, LA Dept of Water and Power, and California Energy Commission. It was located in Daggett, CA, about east of Barstow. Solar One's method of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molten Salt Thermal Storage
Thermal energy storage (TES) is achieved with widely different technologies. Depending on the specific technology, it allows excess thermal energy to be stored and used hours, days, months later, at scales ranging from the individual process, building, multiuser-building, district, town, or region. Usage examples are the balancing of energy demand between daytime and nighttime, storing summer heat for winter heating, or winter cold for summer air conditioning (Seasonal thermal energy storage). Storage media include water or ice-slush tanks, masses of native earth or bedrock accessed with heat exchangers by means of boreholes, deep aquifers contained between impermeable strata; shallow, lined pits filled with gravel and water and insulated at the top, as well as eutectic solutions and phase-change materials. Other sources of thermal energy for storage include heat or cold produced with heat pumps from off-peak, lower cost electric power, a practice called peak shaving; heat fro ...

MW·h
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ). Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities. Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) sustained for (multiplied by) one hour. Expressed in the standard unit of energy in the International System of Units (SI), the joule (symbol J), it is equal to 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 330). Gaithersburg, MD: National Institute of Standards and Technology. 20.
