Thermodynamic Solar: For Legambiente It's a Yes

As the world continues to shift towards a cleaner and more sustainable energy future, innovative technologies like solar thermal power are gaining momentum. In Italy, we have a unique advantage when it comes to harnessing the potential of solar thermal power, thanks to our country’s rich history of technological innovation.

A New Era in Renewable Energy

Solar thermal power, also known as concentrated solar power (CSP), uses mirrors or lenses to focus sunlight onto a heat exchanger, producing steam that drives an electricity-generating turbine. This technology has significant potential for large-scale energy production and storage, making it an attractive solution for reducing our reliance on fossil fuels.

A Winning Formula: Italy’s Innovative Approach

Italy is home to some of the most cutting-edge solar thermal power technologies in the world, thanks in part to the pioneering work of physicist Carlo Rubbia. The “salis fusi” technology developed by Enea has shown remarkable results, using salt at high temperatures (up to 550°C) as a heat exchanger instead of traditional oils.

A New Era for Renewable Energy: Legambiente and ANEST Join Forces

To promote the development of solar thermal power in Italy, Legambiente and the Association of National Solar Thermal Power (ANEST) have signed an agreement outlining guidelines for new projects. The three key pillars of this collaboration are:

Identifying suitable locations for new solar thermal power plants, avoiding environmentally sensitive areas and protecting natural habitats.
Measures to compensate for land loss, through environmental restoration and upgrading infrastructure in affected zones.
Transparency and public engagement, ensuring that communities are informed about the benefits and risks associated with these projects.

The vice-president of Legambiente, Stefano Ciafani, highlights the importance of solar thermal power as a technology that allows for energy storage. However, he emphasizes the need to carefully select locations for new plants, minimizing their impact on the environment and local ecosystems.

So, What is Solar Thermal Power?

In simple terms, solar thermal power uses mirrors or lenses to focus sunlight onto a heat exchanger, producing steam that drives an electricity-generating turbine. This technology differs from traditional photovoltaic systems in its ability to generate electricity at scale, similar to traditional fossil fuel-based power plants.

A Key Differentiator: Scale and Application

Solar thermal power is not suitable for domestic applications, unlike photovoltaics. However, the latest advancements in small-scale solar thermal power technologies offer promising solutions for families looking to harness renewable energy.

From Theory to Practice: Italy’s Leading Role in Solar Thermal Power

The first salis fusi plant was inaugurated in 2013 by Archimede Solar Energy at Massa Martana (Perugia). This pioneering technology has been developed and patented by Enea, paving the way for future innovations in solar thermal power.

What’s Next? The Future of Renewable Energy

As we move forward, solar thermal power is poised to play a significant role in our transition to a cleaner energy landscape. With its potential for large-scale energy production and storage, this technology has the power to transform our relationship with fossil fuels and reduce our carbon footprint.
