The geothermal power generation market size is projected to reach US$ 27,149.2 million by 2031 from US$ 15,453.3 million in 2023. The market is expected to register a CAGR of 7.3% during 2023–2031. Growing role of geothermal power in future energy transition is likely to remain key trend in the market.

Geothermal Power Generation Market Analysis

Geothermal power generation is a clean, sustainable, and environmentally friendly method that taps into the Earth's internal heat to produce electricity. This process involves harnessing the natural steam or hot water reservoirs found beneath the Earth's surface. Flash steam power plants accounted for 64.6% of the total geothermal power generation market share globally.

Further, the rising demand for electricity from end users, such as residential, commercial, and industrial sectors, is anticipated to fuel the market growth during the forecast period. Industrial users accounted for 45.4% of the total geothermal power generation in the world, owing to the rise in demand for electricity for various industrial applications such as manufacturing, chemical, petrochemical, processing, and others. Asia Pacific accounted for the largest geothermal power generation market share, i.e., about 40.4%, in 2022.

Geothermal Power Generation Market Overview

The geothermal power generation market growth is linked to the geological conditions favorable for tapping into the Earth's internal heat. The Earth's geology influences geothermal power's global distribution, and regions with high volcanic activity, tectonic plate boundaries, or hotspots are more likely to have significant geothermal resources. While some regions have been at the forefront of geothermal development, ongoing advancements in technology, such as enhanced geothermal systems (EGS), are expanding the reach of geothermal power, making it an increasingly viable option for clean and sustainable energy worldwide.

Geothermal power aligns with global energy transition goals, which aim to reduce carbon emissions and increase reliance on renewable energy sources. As countries commit to international agreements like the Paris Agreement, the role of geothermal power becomes more prominent in achieving carbon neutrality. The reliable and low-carbon nature of geothermal energy makes it an integral part of the clean energy transition. Governments worldwide incorporate geothermal power into their energy transition strategies, setting targets for increased renewable energy capacity and reduced reliance on fossil fuels. The global shift toward sustainable energy practices emphasizes the importance of geothermal power in achieving broader environmental and climate goals.

Geothermal Power Generation Market Drivers and Opportunities

Low greenhouse gas emissions from geothermal power to Favor Market

The global growth in energy demand, driven by population growth and industrialization, necessitates the expansion of energy production. The expansion of energy production from fossil fuel-based plants has resulted in a rise in greenhouse gas emissions, which, in turn, is expected to increase the need for renewable power generation. Thus, a rise in the demand for reducing greenhouse gas emissions is expected to drive the geothermal power generation market growth from 2023 to 2031.

In addition, geothermal power is characterized by its low greenhouse gas emissions during both construction and operation. Unlike fossil fuel-based power plants, geothermal facilities produce minimal carbon dioxide and other pollutants. The emissions are primarily from the release of gases in small amounts, such as hydrogen sulfide, which are effectively managed and mitigated. The environmental impact of geothermal power is significantly lower than traditional energy sources, making it a cleaner and more sustainable option. As countries strive to reduce their carbon footprint and combat climate change, the low emissions profile of geothermal power positions it as a crucial component in the transition to a greener and more sustainable energy landscape.

Untapped Geothermal Potential in Emerging Economies

Heat flows from the Earth's interior that covers twice the global energy demand. In order to harness this heat, there is a requirement to drill deep underground and convert that heat into a usable form of energy. This is considered a difficult and expensive process; hence, geothermal energy, sometimes referred to as the forgotten renewable energy, only accounts for ~0.3% of global electricity production.  Another main advantage of geothermal energy is that it can provide baseload capacity, which is the minimum amount of electricity that must be available on the grid at any given time. While solar and wind output fluctuates seasonally and throughout the day, geothermal generation can be adjusted in the same way that a fossil fuel power plant can increase or decrease output.

In addition, the government initiatives toward exploring the untapped geothermal potential globally. For instance, to help countries unlock the untapped potential of geothermal energy and promote its widespread use, the International Renewable Energy Agency (IRENA) established the Global Geothermal Alliance (GGA) in 2015 as a platform to improve dialogue, collaboration, and coordinated action to increase the share of geothermal power installed as well as heat generation worldwide. Moreover, Indonesia, Turkey, and Kenya are key economies expected to lead in geothermal electricity generation by the end of 2030. The economic development plan named Kenya Vision 2030 by the Government of Kenya aimed at reaching 5 GW of geothermal capacity by 2030. Thus, exploring the untapped geothermal potential in emerging economies is expected to create several opportunities for the geothermal power generation market growth during the forecast period.
