Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors.
Nevada Solar One is a concentrated solar power plant, with a nominal capacity of 64 MW and maximum steam turbine power output up to 72 MW net (75 MW gross), spread over an area of 400 acres (160 ha). The projected CO2 emissions avoided is equivalent to taking approximately 20,000 cars off the road. The project required an investment of $266 million USD, and the project officially went into operation in June 2007. Electricity production is estimated to be 134 GWh (gigawatt hours) per year.
Abengoa Solar is a subsidiary of Abengoa. Its primary activities include designing, promotion, financing attainment, construction and operation of solar power stations that use photovoltaics, concentrated photovoltaics, or concentrated solar thermal technologies.
There are several solar power plants in the Mojave Desert which supply power to the electricity grid. Insolation in the Mojave Desert is among the best available in the United States, and some significant population centers are located in the area. These plants can generally be built in a few years because solar plants are built almost entirely with modular, readily available materials. Solar Energy Generating Systems (SEGS) is the name given to nine solar power plants in the Mojave Desert which were built in the 1980s, the first commercial solar plant. These plants have a combined capacity of 354 megawatts (MW) which made them the largest solar power installation in the world, until Ivanpah Solar Power Facility was finished in 2014.
Spain is one of the first countries to deploy large-scale solar photovoltaics, and is the world leader in concentrated solar power (CSP) production.
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy. In 2019, nearly 75% of new installed electricity generation capacity used renewable energy and the International Energy Agency (IEA) has predicted that by 2025, renewable capacity will meet 35% of global power generation.
The renewable-energy industry is the part of the energy industry focusing on new and appropriate renewable energy technologies. Investors worldwide have paid greater attention to this emerging industry in recent years. In many cases, this has translated into rapid renewable energy commercialization and considerable industry expansion. The wind power, solar power and hydroelectric power industries provide good examples of this.
Sopogy was a solar thermal technology supplier founded in 2002 at the Honolulu, Hawaii-based clean technology incubator known as Energy Laboratories. The company began its research on concentrating solar thermal energy to produce solar steam and thermal heat for absorption chillers or industrial process heat. The company has also developed applications that incorporate its solar collectors to generate electricity and desalination. Sopogy's name origin comes from industry key words "So" from solar "po" from power and "gy" from energy and technology. The company has its OEM and IPP sales teams along with research and development located in Honolulu, and in 2006 expanded its manufacturing, C&I and oil and gas sales teams in its Silicon Valley facility. Pacific Business News and Greentech Media reported that the VC-funded micro-concentrator solar power firm was shutting down operations based on statements from its President David Fernandez, however Hitachi Power Systems acquired Sopogy in a private transaction in 2014.
The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix. It was completed in 2013. When commissioned, it was the largest parabolic trough plant in the world, and the first U.S. solar plant with molten salt thermal energy storage. Built by the Spanish company Abengoa Solar, the project can produce up to 280 megawatts (MW) gross, supplied by two 140 MW gross (125 MW net) steam turbine generators: enough electricity to meet the needs of approximately 70,000 homes and obviate the emission of roughly 475,000 tons of CO2 every year. Its name is the Spanish term for "sunny spot".
The PS20 solar power plant (PS20) solar power plant is a solar thermal energy plant in Sanlucar la Mayor near Seville in Andalusia, Spain. It was the world's most powerful solar power tower until the Ivanpah Solar Power Facility in California became operational in 2014. The 20 megawatt (MW) solar power tower produces electricity with large movable mirrors called heliostats.
Concentrated solar power systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine connected to an electrical power generator or powers a thermochemical reaction.
Shams Solar Power Station is a concentrating solar power station near Madinat Zayed, Abu Dhabi, the United Arab Emirates. The solar power station is located approximately 120 kilometres (75 mi) southwest of Abu Dhabi and 6 kilometres (4 mi) from Madinat Zayed on the road from Tarif to the Liwa Oasis.
Holaniku at Keahole Point is a 2MW micro-scaled concentrated solar power plant in the Kona District of the island of Hawaiʻi. It is located in the Natural Energy Laboratory of Hawaii at Keahole Point.
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural (off-grid) energy services. Based on REN21's 2014 report, renewables contributed 19 percent to our global energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively.
Areva Solar was part of the renewable energies portfolio of the French nuclear group Areva, headquartered in Mountain View, California, with offices in the United States and Australia. It designed, manufactured and installed solar steam generators for electric power production and industrial steam uses. Before 2010, the company existed as Ausra Inc. In August 2014, AREVA announced it was shuttering AREVA Solar.
The Mojave Solar Project (MSP) is a concentrated solar power (CSP) facility in the Mojave Desert in California, about 20 miles (32 km) northwest of Barstow. Surrounding the hamlet of Lockhart, Mojave Solar is adjacent to Harper Lake and the SEGS VIII–IX solar plant.
Solar power in South Africa includes photovoltaics (PV) as well as concentrated solar power (CSP). As of 2023, South Africa had over 2700 MW of installed PV solar power capacity in its grid, in addition to 500 MW of CSP. Installed capacity is expected to reach 8,400 MW by 2030.
Darren T. Kimura is an American businessman, inventor, and investor. He is best known as the inventor of micro concentrated solar power (CSP) technology known as MicroCSP.
Cerro Dominador Solar Power Plant is a 210-megawatt (MW) combined concentrated solar power and photovoltaic plant located in the commune of María Elena in the Antofagasta Region of Chile, about 24 kilometres (15 mi) west-northwest of Sierra Gorda. The project was approved by the Chilean government in 2013 and construction was started by Abengoa Solar Chile, a branch of the multinational Abengoa Spain. The plant was inaugurated on June 8, 2021. A follow-up project called Likana Solar bid $33.99/MWh in an auction in August 2021.
