High-temperature and corrosion-resistant materials improve plant efficiency and durability, lowering maintenance costs over the project lifespan. Standardizing plant components allows for prefabrication and faster construction, leading to reduced project timelines and costs. Overall, advancements in drilling and power plant technologies are transforming the geothermal energy market by making it more accessible and economically viable. These advancements, coupled with other favorable trends, pave the way for continued market growth and contribute to a cleaner, more sustainable energy future.

Increase in Clean Electricity Generation Across the Globe to Boost the Market

Globally, the demand for clean electricity is increasing at a steady pace. Countries across the globe have already started focusing on increasing clean electricity generation to meet the growing demand. For instance, electricity demand in Mexico is anticipated to grow by 3.5% over the long-run forecast period. The country generated 86.27 Terawatt hours, which is 26.7% of electricity from clean energy in 2021. Increasing demand potential combined with the government's mandate for 35% electricity generated from non-fossil sources by 2024 opens up the requirement for renewable energy sources. The electricity demand in Mexico is expected to grow by over 12% by 2024, meeting the clean electricity generation target.

The U.S. targets maximum renewable electricity output. The primary focus area would be the Geothermal District Heating (GDH). According to the GeoVision report, the U.S. has the potential for 17,500 Geothermal District Heating (GDH) systems to operate by 2050. Currently, 23 GDH systems are in operation across the U.S. Considering the potential of the geothermal sector and growing renewable power requirements, a considerable place is still vacant across the energy sector in the United States.

Geothermal Energy Market Growth Factors

Shift toward Renewables to Increase Demand for Geothermal Energy

Globally, geothermal power generation is escalating steadily with the growing demand for renewable energy. Several governments are taking green initiatives globally to overcome greenhouse gas emissions. Generating energy with no or few greenhouse gas emissions will reduce air pollution. Geothermal power is reducing the dependency on the energy generated from fossil fuels. Geothermal power plants emit 99% less carbon dioxide than fossil fuels. Since the energy is one of the most reliable sources of energy, which is cost-effective, sustainable, and environment friendly, the market demand for this renewable source of energy will continually be increasing as the world is looking for renewable solutions to a great extent.

Growing Heating Requirement Across Residential and Commercial Sectors Boosting the Demand for Geothermal Energy

The global population is increasing at a steady pace. With an increase in the global population, the construction sector is also booming. Residential and commercial building construction has been growing significantly due to the steady rise in population. Several heat networks have been built across the globe to fulfill the growing residential and commercial heating requirements such as space heating and water heating. Geothermal power is a convenient source for district heating; a huge part of the energy is being used in residential and commercial buildings globally. So with the increasing building construction and growing heating requirements, the demand for geothermal power is also increasing.

RESTRAINING FACTORS

Alternative Renewables Options May Hinder the Market in the Long Run

Although geothermal energy is one of the convenient sources for several residential, commercial, and industrial applications, the availability and accessibility are not at par. The energy is restricted to specific locations and limited to certain areas in terms of energy distribution.

Moreover, geothermal power is considered one of the comprehensive sources due to vast monetary requirements from drilling to setting up a plant. A geothermal plant with a one-megawatt capacity will need USD 2 million - USD 7 million. Other renewable energy sources, such as onshore wind, offshore wind power, and solar photovoltaics, still offer lower costs due to the low cost incurred in the production. So, considering the long-term perspective, other renewable sources are expected to hamper the geothermal energy market share.

Geothermal Energy Market Segmentation Analysis

By Type Analysis

Increasing Requirement for Low-cost Energy Fuels the Demand for Binary Cycle

Based on type, the market is categorized into binary cycle, flash, and dry steam. In the global market, the binary cycle segment holds the maximum share owing to lowest cost and best performance benefits compared to other geothermal types. In a binary cycle geothermal power plant, the water is pumped from the geothermal reservoir via a heat exchanger, where it heats isobutene. Steam or water reservoirs under the earth's surface are never directly in contact with turbines in the binary cycle.

Globally, most geothermal areas contain moderate temperatures (below 400°F). The binary cycle power plants are best suited for the extraction of moderate-temperature geothermal. Hence, the binary cycle geothermal plants' overall installed capacity is much more than other geothermal types. In the long-run, the capacity addition from the binary cycle will be steady and continue its dominating position in the geothermal power sector.

Dry steam is the old type of energy production process developed decades ago. This type always has cost advantages compared to binary cycle as it collects and uses steam to run the turbine directly from the reservoir. The U.S. has the highest capacity for dry steam-powered plants. Most of the U.S. geothermal resources near the earth's surface are close to the western part of the country and Hawaii. California generated most electricity from geothermal power across the nation.

By Application Analysis

Growing Energy Demand across Commercial Applications Driving the Market

Based on application, the market is segmented into residential, commercial, industrial, and others. The commercial segment holds the majority global market share. Increasing heat pump uses for air-conditioning and cooling down inside the environment when needed provide a controlled climate in the commercial sector, including office buildings, hotels, schools, and hospitals, which is the primary reason behind the geothermal power demand in the commercial sector. Moreover, this type of energy is utilized for heating and cooling purposes in homes. Apart from this, district heating is also one of the primary contributors to geothermal energy in residential buildings.

Industries, such as pulp and paper, cement, food, aquaculture, lumber, and more, use geothermal heat for various applications. The cement industry uses geothermal heat to dry the materials they produce. The growing requirement for renewable energy in industrial applications is primarily to reduce greenhouse emissions conveniently. The industrial application of the energy has shown a nominal year-on-year growth during 2020 and 2021. Although the geothermal energy market growth prospect in terms of geothermal consumption in the industrial sector is higher as the demand for clean energy increases steadily to reduce GHG emissions.
