A promising technology in renewable energy sector where a plant that produces energy from sun and sand begins operation in Italy’s Sicily.
It is a 2-megawatt modular unit of solar thermo electric power (STEM) technology where solar radiation captured by 786 heliostats is concentrated on a secondary reflector made of flat mirrors and focused in a receiver positioned at ground level.
For the first time ever, the receiver is based on a fluidized bed of sand that is able to absorb, store and transfer heat to produce steam for the conversion into electricity and other thermal uses, as technicians explains at the plant launch to Xinhua.
Giovanni Valotti, chairman of Italy’s largest multi-utility company A2A stresses that the technology were not only totally clean, but it will give unprecedented possibility to store solar for use on demand at night and on sunless days and all without batteries.
“Our key words are environmental sustainability and social responsibility,” Valotti told journalists.
“All leading companies in the world should have the objective not only to benefit themselves but to improve environment and society,” Valotti elaborated.
However, with the threat of global warming accelerating, STEM is a significant international advance in concentrated solar power compared to existing systems which use molten salt for heat transfer and storage, said former South Australian premier Mike Rann, who took part in the launch ceremony along with local authorities.
Since the threat of global warming is accelerating, Mike Rann, former South Australian premier who attended the ceremony along with local authorities said that STEM could be a significant international advance in concentrated solar power compared to existing systems that uses molten salt for heat transfer and storage.
“STEM can produce a huge amount of energy, is incredibly cost efficient and can have fantastic applications in many parts of the world where the sun shines like Australia, Asia and Africa,” said Rann who has special interest in renewable energy told Xinhua.
Rann pointed out, “The sun provides enough energy every hour for the planet to be powered for all year, and if we are smart then we would grab it,”
A2A CEO Luca Valerio Camerano wished Italy can have talks with China on this brand new technology.
“Our idea is trying to explore whether we can export our green technology to China and help fill the existing infrastructure deficit there,” Camerano told Xinhua.
Also, Mario Magaldi, the head of Magaldi group wished that his family company with 120 years of experience in green solutions could be able to build partnerships with China.
“Presently all big countries of the world are under pressure to develop clean energies. In this common effort, collaboration is fundamental to enhance good businesses that not only help save the planet but are more efficient and cheaper at the same time,” Magaldi said.
