Concentrating Solar Power
-
In many ways, space is the perfect place for a solar energy array. In other ways, it poses massive technical challenges. China's Xidian University has begun testing the full range of space solar functions with a purpose-built 75-meter tower facility.

Mining giant Rio Tinto has announced plans to install a pilot version of Heliogen's high-temperature "solar refinery" at a Californian boron mine, supplying clean energy as well as heat for industrial processes, with operations set to start in 2022.
-
A new project in the Australian Outback will trial an innovative technique for converting solar energy into hydrogen by capturing moisture from the air and splitting it via hydrolysis, making it possible for hot, arid areas to become energy exporters.
-
California-based Heliogen has reaching temperatures of more than 1,000° C (1,832° F) with its concentrating solar thermal system, expanding the technology's potential from electricity generation to various industrial processes.

Concentrating solar power (CSP) plants can be a key part of a renewable energy strategy, but progress is often focused on larger facilities. Now, engineers from Sandia National Laboratories are improving the efficiency of smaller plants, designing a new receiver that can absorb much more sunlight.

Australian scientists are no strangers to world records for solar power: in 2014, the CSIRO superheated steam, and in May, UNSW achieved 34.5 percent efficiency in directly converting sunlight to electricity. Now, ANU hit a new record of 97 percent efficiency in converting sunlight into steam.

Concentrating solar power (CSP) systems use the sun’s thermal energy to produce steam and generate power through a turbine. Now, MHPS is testing the performance of a new hybrid system, which takes some of the pressure off a CSP setup by combining it with a Fresnel evaporator, increasing efficiency.
-
For five years now, an experimental Tulip concentrating solar power plant has been operating at a kibbutz in Israel. Soon, however, the world's first commercial Tulip plant will be built for a paying client, in Ethiopia.
-
The Ivanpah Solar Electric Generating System is now fully operational. The 392 MW plant is expected to generate enough electricity to power 140,000 homes each year. NRG announced last week that each of the plant's three units is now supplying electricity to California’s grid.
-
Cogenra has installed a cogeneration solar system at SoCalGas' Energy Resource Center, to show it can work for cooling purposes as well.
-
AORA's Tulip system uses the sun's rays to heat air, which is then used to spin a turbine, creating electricity.
-
Taking inspiration from the sunflower, researchers have devised a more efficient design that would allow Concentrated Solar Power (CSP) plants to be constructed on a much smaller area.
