Swiss high-temperature solar system

Can solar energy deliver heat at high temperatures?

Using solar radiation, they have engineered a device that can deliver heat at the high temperatures needed for the production processes. The team led by Emiliano Casati, a scientist in the Energy and Process Systems Engineering Group, and Aldo Steinfeld, Professor of Renewable Energy Carriers, has developed a thermal trap.

Can a solar receiver transmit solar energy at a high temperature?

However, this technology has difficulties transferring solar energy efficiently above 1,000°C. To boost the efficiency of solar receivers, Casati turned to semitransparent materials such as quartz, which can trap sunlight -- a phenomenon called the thermal-trap effect.

Can solar power generate heat over 1000 degrees Celsius?

Cell Press. (2024, May 15). Scientists generate heat over 1,000 degrees Celsius with solar power instead of fossil fuel. ScienceDaily. Retrieved November 1, 2024 from 240515122039.htm

How does a thermal trap improve solar absorption?

At higher temperatures, heat loss by radiation increases and reduces the efficiency of the plants. A major advantage of the thermal trap developed by ETH Zurich researchers is that it minimises radiative heat losses. Our approach significantly improves the efficiency of solar absorption,” says Casati.

What is solar blind pyrometer temperature measurement?

Solar blind pyrometer temperature measurements in high temperature solar thermal reactors (Transient radiative and conductive heat transfer in ceramic materials subjected to laser heating, Int J Thermophys, 2005, pp. 981 - 999, 10.1007/s10765-005-6679-7): a method for correcting the system-sensor cavity reflection error.

What is the Solar Technology Laboratory at PSI?

The Solar Technology Laboratory at PSI is internationally highly recognized as one of the principal players in the field of solar thermochemical process and reactor engineering. Over the past 25 years, it has demonstrated its leading role with pioneering research and numerous peer-reviewed publications.
