Insight into Solar Thermal Electricity (STE) technology


ABENGOA

STE and PV are two different technologies

STE vs. PV

2

Manageable, which means production can be adapted to energy demand.

Can be hybridized with fossil fuels like natural gas. In conventional plants, this can reduce pollution from atmospheric gas emissions. This can also prolong its useful life.

Promotes socio-economic development by creating employment and industrial infrastructure, which encourage technological development, innovation and

entrepreneurship.

Low-cost.

Wide geographical area of application.

Low maintenance costs: photovoltaic technology does not need major economic investment and human resources for its maintenance.
