Europe is the dominant market for transcritical CO2 systems
September 21, 2015
The global transcritical CO2 refrigeration market was valued at $4.9 billion in 2014, and is forecast to reach $30.7 billion by 2020, growing at a compound annual growth rate (CAGR) of 40.2 percent from 2015 to 2020, according to a report published by MarketsandMarkets.
The following is excerpted from “Case Study: Transcritical Carbon Dioxide Supermarket Refrigeration Systems,” which was prepared by Navigant Consulting Inc. for the Better Buildings Alliance; Building Technologies Office; and the Office of Energy Efficiency and Renewable Energy, U.S. Department of Energy (DOE).
Natural refrigeration technology is gaining traction with end users, yet, despite technological successes, there are still challenges to overcome in the form of regulatory obstacles and skill shortages.
This case study documents one year of operating experience with a transcritical carbon dioxide (TC CO2) booster refrigeration system at Delhaize America’s Hannaford supermarket location in Turner, Maine. This store, which began operation in June 2013, is the first supermarket installation in the U.S. of a TC CO2 booster refrigeration system.
To continue to meet refrigeration needs, f-gas proponents are turning to low-global warming potential (GWP) HFCs and hydrofluoroolefins (HFOs) while advocates of so-called natural solutions — hydrocarbons (HCs), CO2, and ammonia — continue to build their cases.
Hussmann Corp. and Systemes LMP, Quebec, Canada, have announced an alliance to provide customized solutions for CO2 transcritical refrigeration systems. Together, the two companies expect to expand the reach of their products to a broader audience.
CO2 as a refrigerant has been a part of the refrigeration landscape for close to a decade. The most anticipated next step was running CO2 as a standalone refrigerant in a system, which is being done in Europe in more and larger applications. Finally, the approach crossed the Atlantic.
