Global Warming Solutions Begins R&D for LETG Solar Power Plant

Houston-based Global Warming Solutions has initiated R&D for a small light electric thermal generator solar power plant with a capacity of up to 1MW.

The light electric thermal generator (LETG) is a hybrid solar and thermal energy technology that generates energy by heating up liquids that circulate on the surface of a solar panel to produce electricity even during periods of no sunlight.

Global Warming Solutions has previously announced that it was preparing to develop a prototype electricity-generating power plant based on the LETG technology. The plant would be a combination of an LETG with a low-temperature thermal turbine.

The firm said that the rated levelized cost of developing the LETG solar power plant is projected to be 1.9-2.2 times less than the levelized cost of a conventional solar thermal plant.

Alexander Kornaraki, COO of Global Warming Solutions, said: “The LETG produces both electrical and thermal energy. Electrical energy is produced by a photovoltaic process and thermal energy is gathered by the LETG heat-transfer medium. We will now be adding a low-temperature heat to energy converter that will produce even more electricity from the LETG.”
