RE<C: Brayton Project Overview
Google’s Brayton CSP Engine Goals Engine Configuration Selection Engine and System Efficiency Conclusions
RE<C was a Google initiative to drive innovation in renewable energy, with the goal of making renewable energy cheap enough to compete head-to-head with coal-fired power plants. Hence the name RE<C - “renewable energy cheaper than coal.” As part of this initiative, Google formed an engineering team to develop promising technologies in the field of solar energy power generation. After evaluating many technologies, we focused our engineering efforts on concentrating solar power (CSP) because we felt it was an area where we had the biggest opportunity to innovate.
CSP is a proven means of solar power generation and new technologies are lowering its cost curve, but a common characteristic of current CSP technologies is the use of steam turbines for power generation. Steam turbines, although well understood, consume large amounts of water and require extensive balance-of-plant equipment. CSP works best in regions with a lot of sun year-round, and these tend to be desert areas where water is in short supply and permission to use water may be difficult or impossible to obtain.
Examples of different types of CSP: tower, trough, and dish
Our goal for the power conversion part of a CSP plant was to create a new approach that was water-free, modular, and less expensive than steam-based CSP. This led us to examine the Brayton power cycle as a possible solution.
