To meet the ever growing need of the world in terms of energy, technologies are springing up, such technology includes the Na-TECC, (Thermo-Electro-Chemical Converter).
As the world’s population continue to increase, and also projected to increase. there is a growing concern about energy efficiency and sustainability, as the demand for energy increase.
The Thermo-Electro-Chemical Converter also known as Na-TECC is a technology that uses the isothermal expansion of soduim (Na) and solar heat to directly generate electricity. amazing right?
The acronym Na-TECC is derived from soduim (Na) and the intials of Thermo-Electro-Chemical Converter.
The Na-Tech could be considered as an engine, even though it has no moving part.
The Na-TECC is a technology currently under intense development by Shannon Yee, who is currently an assistant professor in Georgia Tech’s George W. Woodruff School of Mechanical Engineering.
Working Principle of the Thermo-Electro-Chemical Converter
Shannon Yee, explained the principle and the goal behind the Na-TECC, he explained that electricity is generated from solar heat by thermally driving a soduim oxidation and reduction reaction on opposite sides of a solid electrolyte.
when this happens the positive charge generated passes through the solid electrolyte due an electrochemical potential produced by the pressure gradient, power is extracted as electrons travel through the external load.
Yee explained that this proceeds is a great way of generating energy because it is efficient. the closed system helps to ensure that available power is optimized without leakages.
the Yee led research work is Funded by the Department of Energy’s (DOE) SunShot Program, the research is being conducted in collaboration with Ceramatec Inc.
some of the major objectives is to reach heat-to-electricity conversion efficiency of more than 45 percent — a substantial increase when compared to 20 percent efficiency for a car engine and 30 percent for most sources on the electric grid.
with the Thermo-Electro-Chemical Converter it is possible to generate energy without spinning turbines, starting noisy and lousy generators.
The development of this tech will lead to increase in energy efficiency, reduction in green house effect.
It is possible to have this engine in your backyard and use it to generate energy, for your domestic use.
