Jason Robbins presents the successes Walgreens has experienced with CO2 trancritical refrigeration. The company sought to test a number of green technologies to define the scalability of the options. The company used best practices experienced throughout Europe to achieve optimal results and have found that the total cost of ownership is lower for natural refrigerant systems. Rob Olden of GI Energy presents Walgreens' transcritical CO₂ system, an innovative solution combined with a geothermal loop, which adds redundancy and increases operational flexibility. In addition to the system overview, he presents the lessons learned throughout the project.
