Spanish engineers have built a thermo solar power station that can shrug off cloudy days and generate electricity 24 hours a day, AFP reported.
The Gemasolar station, located in Andalusia, southern Spain, has a central tower surrounded by 2,600 solar mirrors, each measuring 120 square meters, in an immense 195-hectare circle.
The solar panels reflect sunrays on the tower and energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees Celsius. Those salts are then used to produce steam to turn on the turbines and produce electricity.
It is the station's capacity to store energy that makes Gemasolar so different, because it allows the plant to transmit power during the night, relying on the energy it has accumulated during the day.

據(jù)法新社報(bào)道,西班牙工程師已經(jīng)修建了一座熱能太陽(yáng)能混合電站,這種電站不懼陰天,可24小時(shí)發(fā)電。
吉馬太陽(yáng)能電站位于西班牙南部的安達(dá)盧西亞地區(qū),有一個(gè)中央塔,塔周圍環(huán)繞著2600塊太陽(yáng)反光鏡。反光鏡每塊面積為120平米,鋪成195公頃的大圈。
太陽(yáng)能板將陽(yáng)光反射到中央塔,然后能量?jī)?chǔ)藏在裝有溶鹽的大桶中,溶鹽溫度超過500攝氏度。這些鹽可用于制造蒸汽來(lái)帶動(dòng)渦輪發(fā)電。
正是該電站儲(chǔ)存能量的功能使得其與眾不同,因?yàn)檫@使該電站在夜間依靠白天積攢的能量輸送電能。 |
