Before delving into the benefits and applications of geothermal solutions, it’s crucial to understand how geothermal systems work and the different types available.

How Geothermal Systems Work ? 

Geothermal systems harness the Earth’s natural heat to generate electricity or provide heating and cooling. These systems rely on the heat stored beneath the Earth’s surface, which is accessed through wells drilled into the ground. Water or a heat-transfer fluid is circulated through these wells, absorbing heat from the subsurface and transferring it to a power plant or a heat pump for further use.

Types of Geothermal Systems

There are two main types of geothermal systems: open and closed. Open systems pump groundwater into a building, where it is heated or cooled by the HVAC system before being returned to the ground. Closed systems, on the other hand, circulate a fluid through a closed-loop system, extracting heat from or dissipating heat to the ground. Closed-loop systems, particularly those using vertical wells, are commonly employed in commercial applications due to their efficiency and reduced environmental impact.

The Benefits of Geothermal Solutions

Geothermal solutions offer a myriad of benefits that make them an attractive option for industry and communities striving to achieve net-zero emissions. Let’s explore some of these advantages in detail.
