Concentrated Thermodynamic Solar Power in Italy

The Italian projects for solar concentrated thermal power (SCTP) are among the most significant ones in Sicily, Sardinia, and Basilicata. Other projects of solar thermal energy with concentration are being developed or have been completed in Lombardy and Sardinia. This article will delve into the world of SCTP, exploring its benefits, technology, and current status.

What’s the Difference Between Solar Thermal Power with Concentration and Solar Energy?

The main distinction between SCTP and solar thermal power lies in their final products. In the first case, the outcome is electricity production through a thermodynamic cycle (turbine and generator) or an Organic Rankine Cycle (ORC) system. In the second case, it’s direct heating of water for applications like hot water supply.

This distinction highlights the versatility of SCTP technology, allowing it to be adapted to various energy needs and purposes. By harnessing the power of solar energy, SCTP can provide both heat and electricity, making it an attractive option for industries and households alike.

How Does SCTP Technology Work?

In both cases, the technology uses mirrors (parabolas) to concentrate solar energy and transfer it to a heat exchanger fluid. Enea has developed an Italian, clean, and sustainable technology for SCTP that uses molten salts instead of mineral or synthetic oils.

This innovation enables the efficient collection and utilization of solar energy, minimizing losses and maximizing output. The use of molten salts also allows for greater flexibility in terms of storage and deployment, making SCTP a more practical option for large-scale energy production.

Current Status of Electricity Production from Solar Thermal Power

While current electricity production from SCTP is still too expensive compared to traditional sources, the possibility of combining energy storage systems with SCTP and hybridizing these systems with biomass or other fuels for industrial processes makes this technology highly promising. A wider deployment of these systems should also lead to a rapid decrease in costs.

As the demand for renewable energy continues to grow, the potential benefits of SCTP become increasingly apparent. By leveraging solar energy, SCTP can provide clean, sustainable power while reducing dependence on fossil fuels.

Sicily Leads in Solar Thermal Power Development

The Sicilian region has the most significant number of SCTP projects currently under development. Currently, there are three major projects: Insulation 17 near Mazara del Vallo and Marsala (Trapani province), Reflex Sola Power near Gela, and Gruppo FERA in Noto (Siracusa province).

These projects showcase the potential for SCTP to drive economic growth and job creation in Sicily. By investing in solar thermal power, the region can not only reduce its carbon footprint but also capitalize on new business opportunities.

Sardinia Also Hosts Significant Solar Thermal Power Projects

In Sardinia, there are Villasor and Decimoputzu projects developed by EnergogreenRenewabless, as well as the Medio Campidano projects Gonnosfanadiga and Guspini (the same company). Basilicata is currently pursuing the authorization for a Banzi solar thermal power project in Matera province.

These projects demonstrate Sardinia’s commitment to renewable energy and its potential for growth. By investing in SCTP, Sardinia can create jobs, stimulate local economies, and contribute to a cleaner environment.

Other Solar Thermal Energy with Concentration Projects Are Being Developed

In Lombardy, there’s Gorla Maggiore project, while San Nicolò d’Arcidano in Oristano province is also hosting a development in Sardinia. These projects highlight the widespread interest in SCTP across Italy and demonstrate its potential for growth.

Conclusion

Solar concentrated thermal power (SCTP) is an emerging technology with significant potential for electricity production and heating applications. By leveraging solar energy, SCTP can provide clean, sustainable power while reducing dependence on fossil fuels.

As the demand for renewable energy continues to grow, the benefits of SCTP become increasingly apparent. With its versatility, efficiency, and sustainability, SCTP has the potential to play a major role in Italy’s transition to a cleaner, more environmentally friendly energy mix.
