Geothermal energy, also known as geothermal energy, is one of the clean and renewable sources that relies on the high temperatures that exist - naturally - in the ground, where systems can be operated that exploit this heat to generate steam. This steam then rotates a turbine connected to a generator to generate electricity.

Geothermal energy is usually produced by drilling a deep well in the ground, to reach hot water tanks that are characterized by rising steam. Therefore, this energy is widely considered a sustainable and environmentally friendly source. Because its greenhouse gas emissions are limited, and its environmental impact is limited - as well - compared to traditional fossil fuels.

In this article, we will review with you the extent to which we can rely on this energy, as a clean and sustainable source in the future, highlighting how to extract it, and answer the question: What are the current restrictions on this new type of energy?

How is ground energy generated?

Generating this type of energy requires a series of complex steps, and the beginning is by identifying and exploring places rich in geothermal resources, and this is through geological studies that determine each spot on the Earth’s thermal nature. After determining the appropriate location, a well is drilled in the earth’s crust, to reach hot water or steam tanks, where this water - or steam - is extracted through production wells and transported to the surface. This is for use in power plants.

It is worth noting that there are three types of geothermal power plants.

First- Known as dry steam plants, which use steam coming directly from drilling wells to rotate turbines; And then generate electricity.

Second- Known as steam stations, which transfer hot water from one tank to another with lower pressure, which quickly turns the water into steam. Thus generating electricity.

Third- Double cycle stations, which exploit ground fluids, which are characterized by high boiling points; To heat liquids with a lower boiling point, such as: ammonia or isobutane, where the latter’s vapor is exploited to generate electricity.

Energy AdvantagesGeothermal

Thermal energy offers various benefits as a sustainable energy alternative, as the Earth’s internal heat is a reliable, almost constant energy source that can be accessed at all times, unlike solar and wind energy, which both depend on the weather pattern. Which means they will not be available at all times.

Geothermal energy is considered an environmentally sustainable energy source. Because of their small contribution to greenhouse gas emissions, this is because they differ from fossil fuels in that they do not involve a combustion process; Which reduces air pollution, and avoids any cause of climate change.

Geothermal energy can be used in a wide range of applications - other than electricity production - including the use of geothermal heat pumps - for example - or central heating systems; This is to provide heating and cooling for residential, commercial and industrial activities.

On the economic side, the market for using geothermal energy will provide many job opportunities, in addition to contributing to strengthening local economies and reducing dependence on fossil fuel imports. Here we ask a question: Since geothermal energy is a renewable and sustainable resource, why do we not rely on it more?

Energy defectsGeothermal

Although ground energy is a sustainable and environmentally friendly source - compared to fossil fuels - it suffers from some obstacles that prevent greater reliance on it. The most prominent of these obstacles is the restriction to specific sites according to the natural distribution of geothermal resources, and the process of research and excavation to establish new stations requires huge investments and great technical expertise.

The development and establishment of geothermal power plants may also face obstacles, and these obstacles are represented in obtaining the necessary licenses and permits from various parties, in addition to allocating land, which may take a long time and be high in cost.

Energy developmentGeothermal

In recent years, the field of geothermal energy has witnessed remarkable development, which has contributed to the growth of this industry and increased reliance on it as a source of renewable energy. In addition, drilling technology has advanced significantly; This expanded the range of places that can be exploited to generate this type of energy.

On the other hand, political support played a decisive role in the progress achieved in the field of geothermal energy, as efforts were made to facilitate the implementation of geothermal projects, by establishing clear regulatory frameworks and allocating financial incentives for these projects. Which led to increased investment, research and development in this emerging technology.

In addition to the above, the use of ground energy is gradually making its way to new markets and applications beyond the production of electricity. International partnerships between countries also play an important role in the development of this sustainable industry, as this has facilitated the exchange of knowledge and the transfer of technology. To accelerate joint research and development projects. This cooperation has contributed to accelerating the development of geothermal technologies and introducing them to new regions on a global level.

Energy FutureGeothermal

Geothermal energy represents a promising source in the future. Because of its many advantages, it is renewable energy and a sustainable source that relies on the Earth’s heat without the need to burn any type of fuel. So it can meet our energy needs cleanly for hundreds of centuries to come.

In conclusion, we say that despite the disadvantages of relying entirely on terrestrial energy, it undoubtedly constitutes an essential part of the clean energy future, and a major player in our efforts to achieve the “energy transition.”
