SkyFuel, the US-based concentrated solar power (CSP) manufacturer, has revealed that it won the order for Enel Green Power’s recently announced hybrid geothermal-CSP plant in Nevada.
Colorado-based SkyFuel says that it has already delivered
all the equipment for the parabolic-troughs that will be integrated into EGP’s
existing 33MW Stillwater geothermal plant, which already incorporates 26MW of PV
The addition of the 17MW CSP component – equivalent to 5MW
of additional geothermal generation capacity – will make Stillwater the world’s
first hybrid geothermal-CSP power station, with the CSP element slated for full
operation by the end of 2014.
The CSP field has been designed to return the temperature of
the brine brought up from Stillwater’s geothermal wells to their original
point, thus recapturing the full capacity and economic value of the existing
turbine generator, SkyFuel explains.
Parabolic-trough CSP technology – as opposed to power-tower – is
ideal for hybridizing CSP into an existing thermal-generation project, as it
can scale up or down to almost any size, SkyFuel claims.
Founded in 2007, SkyFuel has been relatively quiet since
2012, when it unveiled plans to enter the emerging Middle Eastern CSP market
via Saudi Arabia – having launched into China the year prior.
The company claims to be able to produce 50MW of parabolic-troughs per year out of its Colorado factory.
“Enel’s choice of our technology is the best validation
SkyFuel could ask for,” says chief commercial officer Kelly Beninga.
SkyFuel’s parabolic-trough system, known as the SkyTrough,
employs glass-free reflective mirrors, which the company says are lighter – and
therefore easier to install and transport – than competing technology.
