Saft will add energy storage to BrightSource concentrating solar power project

Tadiran Batteries, a unit the Saft Group won a contract by Oakland-based BrightSource Energy, a concentrating solar power technology company.

Under this contract Tadiran will provide rechargeable energy packs to power more than 50,000 controllable mirrors — called heliostats — being deployed at the Ashalim Thermal Solar Power Station, located in the Israeli desert that Alstom will build.

BrightSource Energy’s CSP technology produces electricity the same way as fossil fuel power plants — by creating high-temperature steam to turn a conventional turbine. However, instead of using fossil fuels to create the steam, BrightSource uses the sun.

Thousands of individually-controlled heliostats track the sun and reflect sunlight onto a boiler that sits atop a tower. When the concentrated sunlight strikes the solar receiver, it creates superheated steam, which is used to turn a turbine and generate electricity. The Ashalim station will have a total power generating capacity of 121 MW, enough to meet the electricity needs of more than 120,000 homes.

During the day Tadiran’s rechargeable energy storage packs will drive the heliostat motors and power device communications. The rechargeable batteries help eliminate expensive cabling and wiring that would otherwise be required to power the heliostat motors and control modules.

Tadiran Batteries’ proven TLI series based rechargeable batteries will enable at least 25 years of day and night continuous operation. Designed specifically for harsh environments, the TLI Series represents progress in rechargeable battery technology that meets the strict requirements of long-term use under rough desert conditions.
