Outokumpu Delivers Stainless Quarto Plates for Solar Power Project
03/02/2012 - Outokumpu is supplying 650 tonnes of stainless steel quarto plates for the construction of a hot nitrate salt storage tank used at the Crescent Dunes Solar Energy power plant located in Tonapah, Nev. The plates are produced at Outokumpu’s quarto plate unit in Degerfors, Sweden.
Outokumpu is supplying 650 tonnes of stainless steel quarto plates for the construction of a hot nitrate salt storage tank used at the Crescent Dunes Solar Energy power plant located in Tonapah, Nev. The salt storage tank is part of a heat storage system that allows energy to be stored for 10-15 hours.
The quarto plates made out of heat-resistant stainless steel grade 347H are delivered to Felguera IHI, who is responsible for the fabrication all the way to commissioning of the salt storage system to the new solar power plant. The plates are produced at Outokumpu’s quarto plate unit in Degerfors, Sweden.
The salt storage tank’s hot service environment of 600°C sets high requirements on the material selection. Outokumpu’s heat-resistant grade offers high corrosion resistance and the ability to handle elevated temperatures.
The Crescent Dunes Solar Energy power plant, belonging to Solar Reserves, is the first commercial-scale solar power facility in the U.S. and upon completion also the largest of its kind in the world, according to Outokumpu, providing a renewable energy source to about 75,000 households. The project is estimated for completion in 15 months.
"Solar energy is increasing in importance as a renewable energy source due to technological advancements. We hope this case increases the awareness of the use and benefits of stainless steel in the area of solar energy production," said Erik Johansson from Outokumpu.
Outokumpu is a global leader in stainless steel with customers in a wide range of industries worldwide. The company employs about 8000 people in more than 30 countries. The Group's head office is located in Espoo, Finland.
