High-power solar power generation terminal

What is a solar power tower?

Solar Power Towers (SPT), also denominated Central Receiver Systems (CRS), are set up by a heliostats field which reflects solar radiation into a central receiver located atop a tower. These heliostats track the Sun with two axis. They are also considered as point focus collectors.

Are solar power towers a promising technology?

All the issues commented above make solar power towers, among other concentrated solar power technologies, a promising technology with commercial possibilities in the mid term. Better performance and cheaper electricity compared with other options seems within reach.

What is the thermal efficiency of solar power towers?

2.3. Thermo-economic data Regarding efficiency values and as a general overview, it can be highlighted that thermal efficiency (solar to mechanical) is estimated between 30% and 40% for solar power towers.

How do solar power plants work?

The heat can then be used to create steam to drive a turbine to produce electrical power or used as industrial process heat. Concentrating solar power plants built since 2018 integrate thermal energy storage systems to generate electricity during cloudy periods or hours after sunset or before sunrise.

How high can a solar receiver withstand a high temperature?

Quite high temperatures can be reached in the solar receiver, above 1000 K, ensuring a high cycle efficiency. This review is focused to summarize the state-of-the-art of this technology and the open challenges for the next generation of this kind of plants.

Are hybrid solar tower gas turbines a viable technology?

Some already mentioned interesting projects include SOLGATE , SOLHYCO , SOLUGAS and HYGATE , which proved that hybrid solar tower gas turbine systems are a feasible technology that requires more R&D for decreasing electricity prices .
