Laughlin Battery – Google Recuperator
- Google has made a public commitment to renewable energy for their growing data center power demands.
- The Laughlin-Brayton Battery is intended for utility-scale renewable energy storage.
- Brayton designed heat exchangers for the recuperator, molten salt, and hexane fluids.
- The plant layout (right) shows the integrated system, with Brayton’s gas turbine design. The system is clearly dominated by heat exchangers.
- The goals of this project were to design, build, instrument, and test a recuperator and molten salt heat exchangers. This data was use to further validate Brayton analytical design tools.
- Active since 2011, Brayton remains committed to bringing realism to Bob Laughlin’s theory of a high efficiency reversible Brayton cycle energy storage system.
