Why use CO2 heat pumps for central heating?

The current world market for heat pumps is growing rapidly. Virtually all of them use R407C, R410A or R134A, which are very powerful greenhouse gases with relativily high global warming potentionals (GWP). Although the refrigerant leakages from these systems are small, they cannot be neglected. An alternative solution is to utilize refrigerants that don’t have a negative impact on the global environment. For example non-synthetic fluids such as ammonia, hydrocarbons and carbon dioxide. Carbon dioxide (CO2, R744) is one of the few non-toxic and non-flammable fluids that contributes neither to ozone deplation or global  warming. Due to its favourable thermophysical properties, R744 is regarded as an interesting alternative instead of the HFC’s in residential and commercial heat pumps.
