The Issue

In order to meet California's ambitious climate goals, Senate Bill 1383 mandates a reduction in short lived climate pollutants, including a target to reduce hydrofluorocarbon (HFC) emissions by 40 percent below 2013 levels by 2030. Conventional refrigeration systems use HFC-based refrigerants, such as Freon, which have a very high global warming potential (GWP) of approximately 4000 times carbon dioxide (CO2). Transcritical CO2 refrigeration is a commercially available, high efficiency, low-GWP alternative to conventional HFC-based refrigeration. There is a need to demonstrate high efficiency, cost-effective transcritical CO2 refrigeration systems in commercial and industrial facilities.

Project Innovation

The purpose of this project is to install and operate an advanced heat recovery system at the Recipient's meat processing facility. The heat recovery system will be incorporated into an existing, large-scale transcritical carbon dioxide (CO2) refrigeration system in order to recycle waste heat for use in a singer system resulting in reduced onsite greenhouse gas (GHG) emissions, energy consumption, and operating costs. Natural gas consumption will be measured before and after the system is installed in order to quantify and validate the GHG emissions reductions.

Project Benefits

This project will result in GHG and criteria pollutant emission reductions by using waste heat to offset natural gas consumption at the facility.

Environmental & Public Health

Environmental Sustainability

This project is expected to reduce GHG emissions by approximately 2,500 metric tons of carbon dioxide equivalent per year and nitrogen oxide emissions by approximately 6,000 pounds per year.
