The potential of Aquifer Thermal Energy Storage (ATES) is becoming increasingly apparent as a green heating and cooling solution. A recent study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this sector by 40 per cent. If implemented, it could have a significant impact on climate change – creating a more sustainable future for businesses seeking to reduce their carbon footprint.

What Is ATES?

ATES consists of an array of wells connected to one or more heat pumps, which are used to extract warmth from the ground during winter months, and coldness during summer months. This energy is stored in the form of heat and cold, which can be used as a source for heating or cooling buildings.

The Benefits of ATES

ATES is an attractive option for reducing energy costs and improving comfort in homes and businesses, thanks to its efficiency and reliability. By using ground water instead of electricity or gas for heating, this green technology could save up to 40 per cent on energy bills. As well as being cost-effective, it’s also environmentally friendly – reducing carbon emissions by up to two thirds compared to traditional methods.

In addition, ATES provides consistent temperatures year-round because underground temperatures remain relatively stable regardless of external conditions. This means that there’s no need to adjust settings throughout the year, saving time and effort in the process.

Drawbacks of ATES

Although ATES is a promising green technology, it’s not without its drawbacks. The installation costs can be high, as drilling wells and installing heat pumps is an expensive process. Additionally, there are limited areas suitable for installation – such as locations with accessible ground water – which may limit its use to certain regions.

The Future of ATES

Despite these challenges, ATES is growing in popularity due to its potential for reducing energy consumption, emissions and bills. With more businesses looking for ways to reduce their carbon footprint and save money, this green solution could become increasingly attractive in the coming years. As awareness increases and technology advances, ATES could be the green future for heating and cooling buildings.


ATES offers a cost-effective and environmentally friendly solution for heating and cooling buildings, with the potential to reduce energy consumption by up to 40 per cent. Although there are some drawbacks associated with installation costs and limited suitable locations, its popularity is growing as businesses take steps towards sustainability. As technology advances, ATES could become the go-to option for green heating and cooling in the future.
