From the first transcritical CO2-only supermarket in Australia, to an impressive number of CO2 components and systems on display at the international trade fair Chillventa, the year 2008 held some major progress for R744 in refrigeration and cooling. Among the highlights: a clear commitment to CO2 by beverage giant Coca-Cola, a rising trend towards R744 in the US, and CO2 Technology at the Beijing Olympic Games.

Mobile Air Conditioning
The year 2008 started and ended with discussions about a next-generation refrigerant to replace R134a. Narrowed down to two global refrigerant solutions, cross talks divided proponents of CO2 and the chemical alternative 1234yf at key events in Japan, Austria, France, China and the U.S. In October, and right after the German car industry reconfirming its CO2 choice, alarming flammability and toxicity results for 1234yf sparked controversial reactions in Europe and the US. 2008 ends with no clear commitment to CO2 or any other refrigerant besides the one from the German automotive industry.

In 2008, governments around the world acknowledged heat pumps as one of the most sustainable way to achieve energy savings and cut dependency on oil. While the success story of CO2 heat pumps (Eco-Cute) in Japan continued, other world regions, including the EU and US, showed rising interest in the potential that CO2 offers for low-energy passive houses, and industrial processes.
