The video below is an inside look of PS10 solar thermal power station located in Seville, Andalucia, Spain. This type of solar power station is known as solar tower. A very massive type of solar energy sources due to the area occupied by lenses called heliostats that directs sunlight on a single tower.
The tower is where the water is converted into steam by sunlight heat to power a turbine. Newer designs uses liquid sodium and molten salts (40% potassium nitrate, 60% sodium nitrate) as the working fluids. These working fluids have high heat capacity, which can be used to store the energy before using it to boil water to drive turbines. These designs allow power to be generated even when there is no sun unlike conventional solar panels which are operational only when there is sunlight.
PS10 Solar Power Plant
I think this is the future of solar energy generation especially for large industrial consumption. Countries surrounding the equator like the Philippines should start exploring possibilities in order to have this kind of renewable energy sources. Its a common knowledge that this type of energy is inexhaustible and doesn't produce toxic substance and therefore is the major focus of future energy development.
The number of projects will be the driving force on the lowering of power prices for this type of energy sources. The more energy generating plants of this type are develop the lower the electricity cost will be.
