STEM® technology
STEM® (Solar Thermo-Electric Magaldi) is a patented concentrating solar technology, which uses a mirror system to concentrate the sun's light energy on a receiver and convert it into heat.
The heat can be used to power industrial thermal processes or to drive steam turbines to produce electricity.
The STEM® technology contains a TES (Thermal Energy Storage) system directly integrated into the solar receiver that is used to generate energy during cloudy periods and also even when solar radiation is no longer available (eg. hours after sunset or before sunrise). This feature makes STEM® a flexible source of renewable energy that can be dispatched on-demand.
Thermal applications
The International Energy Agency (IEA) claims that heat accounts for approx. 74% of the industrial sector‘s total energy demand.
Power applications
In agreement with what emerges from the document of IRENA “Innovation Outlook TES 2020”, there are currently 93 CSP plants operating worldwide.
