CO2 Heat Pumps //
What Are CO2 Heat Pumps
A heat pump absorbs heat from an ambient temperature source and releases it to a warmer one. It uses an external source, such as air, the ground or water, to transfer energy and it uses a fluid called a refrigerant to facilitate this process. CO2 heat pumps work the same way, by transferring thermal energy, but they use CO2 as the refrigerant fluid. These heat pumps are environmentally friendly because the CO2 they use stays contained within the appliance and doesn’t get released into the atmosphere. Also CO2 is not toxic and only has a GWP (Global Warming Potential) of one much lower than chemical alternatives.

Why Invest in a CO2 Heat Pump
When discussing heat pump efficiencies, the following terms are commonly used: coefficient of performance (COP), seasonal coefficient of performance (SCOP) and seasonal performance factor (SPF). The higher the number, the more efficient a heat pump is, the less energy it consumes, and the more cost-effective it is to operate.
Heat pump technology is well established and works well at all scales. Unfortunately the traditional refrigerant fluids used have very high GWP (global warming potential; a multiple of the impact of CO2, with many being over 600). Regulators have already outlawed the use of the really bad refrigerants and are closing the door on the others, leaving a few low GWP and “natural” refrigerants.
Clade are the UK leaders in the natural refrigerant CO2 with the lowest GWP possible of 1. CO2 is also the easiest to maintain and is comparable in cost to R32 but without the flammability or toxic nature.
What’s the difference between CO2 heat pump and atmospheric CO2?
It is easy for confusion to arise, after all how can a CO2 heat pump help reduce CO2 emissions?
Combustion appliances like boilers and fossil fuel engines continuously produce CO2 as a by product of their operation, this CO2 is released into the atmosphere via the flue or exhaust.
By contrast CO2 heat pumps use Carbon Dioxide as the working fluid, the CO2 is contained permanently within the appliance. It is the thermodynamic properties of the expansion and compression of CO2 that enables a heat pump to work.
The CO2 that Clade use is captured as a by-product of other industrial processes. Unlike other natural refrigerants such as; propane which is component of natural gas, or ammonia which is made in a high carbon process.
Other types of heat pump use different working fluids, typically HFCs or HFOs which contribute more to global warming. This contribution is measured using GWP “global warming potential”, CO2 has the lowest possible score of 1.
Using CO2 heat pumps will result in an improvement in carbon reduction both directly in the heat output and indirectly through the production, service and disposal of the working fluid.
Other advantages of CO2 heat pumps include higher operating temperatures which more closely match existing heating systems and enable greater value in heat recovery. This can reduce the cost of the installation and operation of your facility.
CO2 is non toxic and inert which makes the burden of managing the risks lower than other working fluids.
CO2 Heat Pumps for Residential Applications
The great thing about CO2 heat pumps is that they can be used for both heating and cooling down your residential home. For instance, during the summer when the sun is out, the CO2 heat pump can keep your home nice, cool, and comfortable. To do this, the carbon dioxide will absorb the heat from the air inside your home, and then release it outside.
During the cold winter months, the heat pump can be used to heat your home. To keep your home warm and comfortable, the carbon dioxide will absorb the heat from the air outside, and then release it inside. This all sounds like a very simple and straightforward process, and it really is. It’s the only way we can substantially reduce heating emissions at scale.
How Does a CO2 Heat Pump Work?
A CO2 heat pump uses carbon dioxide as a refrigerant. Carbon dioxide is a naturally occurring gas, and it has a very low boiling point. This makes it ideal for use in a heat pump. When the carbon dioxide is compressed, it becomes a liquid. This liquid then evaporates, and as it does so, it absorbs heat from the surrounding air.
The carbon dioxide then condenses back into a gas, and as it does so, it releases the heat that it absorbed. This process can be repeated over and over again, and it is this that makes a CO2 heat pump so efficient. When it comes to cooling a residential home, a very similar process takes place
CO2 Heat Pump Emissions Info
There’s no secret that every system will lose some of its gas every year as a result of leakage between the components or maintenance activities. However, when compared to CO2, which records an annual loss of around 53kg, the alternative working fluids record losses that are thousands of times higher than CO2 – making carbon dioxide a much more environmentally friendly option.
Aside from that, CO2 is non-flammable, non-corrosive, and non-toxic, which means that it doesn’t decompose within the system or when it is accidentally released. As a result of the above, CO2 heat pumps are the most efficient and cleanest way to heat your home. This is great news for the environment and for your wallet. Not only will you be doing your part to help reduce greenhouse gas emissions, but you’ll also be saving money on your energy bills.
