Greetings, and welcome to Saras LLC.
Who We Are
I am Dr. Suresh Mani, founder and President of Saras LLC. Saras works in the energy storage and renewables space. We are a small business located in beautiful Ann Arbor, Michigan.
Saras has developed a coating for Concentrating Solar Power (CSP) receivers. Our target customers are CSP providers: e.g., Abengoa Solar, Areva, BrightSource, etc. The coating absorbs the heat from sunlight and transfers it to a carrier fluid ,e.g., molten salt which can store the heat until it is needed and then the it is used to convert water to steam that drives turbines to generate electricity.
The coating enables operation at temperatures as high as 800 C vs current coatings that operate at 400 C. Operation at higher temperatures improves the Carnot efficiency and reduces the cost of CSP electricity. We have begun working with Prof. Pitchumani, Virginia Tech, to make the Saras coating spectrally selective. This spectrally selective coating will be optimized to have high solar absorptance while minimizing radiation losses. This coating is a game changer and will reduce the cost of solarthermal electricity from 13 to 6 cents/kWh.
