Indian scientists develop test bed to generate clean energy

IANS  |  Bengaluru 

Indian scientists have developed a supercritical (CO2) Brayton test facility at the (IISc) here to generate from power plants, including solar thermal, the premier institute said on Thursday.

Touted to be the first in the country, the Brayton cycle test loop facility was unveiled by of Science and Technology Harsh Vardhan here.

The facility is part of the Indo-US consortium -- Solar Energy Institute for India and the (SERIIUS).

"The test bed was developed by a group at the inter-disciplinary centre for energy of the IISc as part of the consortium," an institute statement said.

Funding was provided by the Indian government's under the and Development Centre programme.

The new-generation high-efficiency power plants with closed cycle CO2 as the working fluid have the potential to replace steam-based nuclear and thermal power plants, thus reducing the carbon foot print significantly, the IISc said.

"This breakthrough research could potentially be game changer for meeting the of the country in terms of higher efficiency and capacity at lower operating costs and size," Vardhan said while speaking on the occasion.

While the current day's thermal power plants would use steam to carry the heat and turn a turbine to generate power, the research makes use of supercritical CO2 (SCO2) instead of steam to generate more power.

Supercritical refers to the state of above its critical temperature of 31 C and critical pressure of 73 atmospheres, which makes it twice as dense as steam.

"Besides increasing power generation and making the process more efficient, there are other advantages of using this new technology like making the power plants cheaper with lower operating costs," the statement added.
