One conundrum for the two main Concentrated Solar Power (CSP) technologies is how to be both bankable and efficient. Parabolic trough CSP is often considered more bankable, while central tower plants are more efficient. Trough technology is about a decade older than tower and has built up experienced supply chains, [...]
Engineers generally tend to be solutions-oriented, and engineers in Concentrating Solar Power (CSP) are no different. A history of making things better than they were is why we now have advanced technologies. As Hal Harvey, founder of Energy Innovation told the NYT opinion columnist Tom Friedman: “A prime difference between [...]
The US National Renewable Energy Laboratory (NREL) published June 12 the world's first global best practice report for Concentrated Solar Power plants. The report sets out recommendations to improve the performance and reliability of Concentrating Solar Power tower and trough plants, using feedback from 80% of global CSP capacity. [...]
So, you want to build a concentrated solar power (CSP) plant. Have you developed a technical specification that clearly defines the key project requirements? Does your team have the relevant experience and knowledge to successfully deploy a solar thermal project? Have you designed your plant for the daily start-ups and [...]
NREL's High-Flux Solar Furnace (HFSF) is a unique 10-kilowatt optical furnace that harnesses concentrated sunlight to test high-temperature processes or applications requiring high heating rates or solar concentration. At the top of NREL's South Table Mountain campus, the HFSF is a unique user facility for testing high-temperature processes and applications. [...]
On November 6, 2019, the U.S. Department of Energy Solar Energy Technologies Office awarded $128 million to 75 new projects that will advance solar technologies in five major areas. The National Renewable Energy Laboratory (NREL) earned a major portion of this funding—nearly $20 million. Each innovative project will work [...]
ARPA-E has challenged researchers to innovate a storage technology that can be deployed in almost any location and charge and discharge electricity, at a low fixed cost per cycle, for up to 4 days. The DAYS (Duration Addition to electricitY Storage) challenge is to supply an unmet market need – [...]
With seven new projects, NREL will elevate research in concentrating solar power (CSP). The projects are funded by the U.S. Department of Energy's Solar Energy Technologies Office (SETO) through a National Laboratory call for proposals. NREL's CSP work is part of the Department of Energy's CSP program, which supports early-stage [...]
Mark Mehos manages both the Thermal Sciences R&D group and the Concentrating Solar Power (CSP) Program at the National Renewable Energy Laboratory (NREL). The emphasis of NREL’s CSP program is the development of low-cost, high-performance, and high-reliability systems that use concentrated sunlight to generate power. Mark is also the [...]
Next-generation concentrating solar power (CSP) plants require high-temperature fluids, like molten salts, in the range of 550-750 degrees Celsius to store heat and generate electricity. At those high temperatures, however, the molten salts eat away at common alloys used in the heat exchangers, piping, and storage vessels of CSP systems. [...]
The Ivanpah Solar Electric Generating System in California (US), the world’s largest solar power plant, is a concentrating solar power (CSP) complex that uses more than 300,000 mirrors to generate electricity. On 19 May when a small fire shut down a generating tower the mainstream press jumped on the news [...]
Reducing the cost of Concentrated Solar Power (CSP)-generated electricity, however, requires improving the efficiency of this conversion.
NREL study finds additional value with 6–9 hours of storage in concentrated solar power (CSP) plants
NREL found that the value of energy delivered by dry-cooled parabolic trough and solar power tower plants with storage is similar.
