Greeley Performance update Dec 2023

Lineage - Greeley Performance Update

On a high level, the Greeley IcePoint unit is matching its design spec and meeting its thermal performance metrics. The thermodynamics at full scale have been proven. 

Below is a snapshot of the data taken since commissioning in April 2023. The high moisture capture rate of 90% matches the model very well.  Another highlight is the unit has made over 1.2 million pounds of ice! 
 
During the summer we realized the wet scrubber performance was not making spec and the air/brine temperatures were too high.  Our engineers specified new packing material, which resulted in a 10X improvement in heat exchanger efficiency – shown below.

Also, the demand response (thermal battery) performance of IcePoint has been proven at 100% capacity for up to 3 hours and 50% capacity for the entire Xcel Energy demand response period. Here is a plot of power consumption approaching zero as cooling and dehumidification benefits are provided to the facility for 5 hours.
