Geothermal Turbines Market Growth Factors

Government Support and Incentives

Governments and regulatory bodies worldwide frequently provide financial incentives, subsidies, tax breaks, and favorable regulations to encourage geothermal energy development. Governments frequently offer feed-in tariffs (FiTs) and power purchase agreements (PPAs) that ensure set rates and long-term commitments to geothermal power companies. The Philippines, for example, has established FiTs to encourage geothermal energy development, with prices ranging depending on project size and location.

Furthermore, several countries offer investment tax credits, grants, and subsidies to help geothermal project developers minimize their financial burden. The federal Investment Tax Credit (ITC) in the United States provides incentives for qualifying geothermal projects. The ITC has been a strong driver of geothermal project investments in the United States. It provides a 26% tax credit for qualifying projects, resulting in greater development and capacity additions. Governments may also give loan guarantees and risk mitigation measures to entice private investment. For example, the U.S. Department of Energy's Loan Programs Office provides loan guarantees to geothermal projects, lowering developers' financing risks. As a result, government assistance and incentives are an important aspect of the global geothermal turbine market trend.

Market Restraints

High Initial Investment

Developing geothermal power projects requires exploration, drilling, and infrastructure investments. Exploration of geothermal resources can be costly, especially in areas with no recent geothermal development. With its immense geothermal potential, Indonesia exemplifies the difficulties of substantial initial investment. Creating new geothermal fields in remote places necessitates major investment in discovery, drilling, and power plant construction. For example, the Sarulla Geothermal Power Plant in North Sumatra, Indonesia, required a significant investment of more than USD 1.17 billion. The cost breakdown of a geothermal power project, according to the U.S. Department of Energy, typically includes exploration and drilling (up to 30% of total project cost), surface power plant (30-40%), and transmission and interconnection (10-20%).

Concurrently, the cost of producing geothermal electricity in India is considerable. If the site must be drilled more than 200 meters, it costs Rs 40 crores (about $5.3 million) to create 1 M.W. As a result of the large initial capital needs, emerging economies may struggle to attract investments, stifling the spread of geothermal energy in these countries.

Key Opportunity

Renewable Energy Transition

Geothermal energy is a reliable and consistent choice as the globe attempts to lessen its dependency on fossil fuels and migrate to renewable energy sources. The switch to renewables creates prospects for geothermal power capacity increase. Geothermal energy, being a renewable resource, meets a large portion of electricity demand in nations such as Iceland, El Salvador, New Zealand, Kenya, and the Philippines, and more than 90% of heating demand in Iceland. Iceland's Hellisheii Geothermal Power Plant. Iceland's Hellisheii Geothermal Power Plant is one of the world's largest geothermal plants. It generates power and hot water for district heating by combining geothermal and hydrothermal resources.

According to the International Geothermal Association (IGA), global geothermal power generation capacity could reach 28,000 MW within 15-20 years. With continued development, IGA intends to add 4,500 MW of power generation capacity over the next five years. Asia, Africa, Europe, and North America remain key growth markets.

Regional Insights

Asia-Pacific: Dominant Region with 4.5% Growth Rate

Asia-Pacific is the most significant global geothermal turbine market shareholder and is estimated to grow at a CAGR of 4.5% over the forecast period.The national government has been pushed to act and pass legislation due to these economies' immense potential for geothermal energy generation. These policies enable oil and gas companies to explore regional geothermal energy possibilities, promoting market expansion. Indonesia, the Philippines, and Japan are at the forefront of the geothermal sector in the Asia-Pacific area. Geothermal energy accounts for around 10% of electricity generation in the Philippines. As numerous new geothermal power projects are planned in the country, the country is projected to have a greater share of geothermal electricity shortly.

Furthermore, the Wayang Windu Geothermal Power Station is an example of an Asian-Pacific project. It uses Indonesia's extensive geothermal resources, adding to its renewable energy ambitions. The power station, which has a more than 200 MW capacity, employs binary cycle technology.

North America: Fastest Growing Region with 4.9% Growth Rate

North America is anticipated to exhibit a CAGR of 4.9% over the forecast period. The United States is expected to increase greatly during the projection period. Geothermal energy presently accounts for 0.4% of U.S. electricity generation.

Geothermal Turbines Market Segmentation Analysis

By Type

Based on type, the market is further segmented into Dry Steam, Flash Cycle, and Binary Cycle. Binary Cycle holds the maximum share of the market. For lower-temperature geothermal resources, binary cycle power plants are constructed. They use a secondary working fluid with a lower boiling point (e.g., isobutane) to collect heat from geothermal water. To create energy, the working fluid vaporizes and drives a secondary turbine. During the forecast period, the binary Cycle is the fastest-growing segment. This is because most binary plants are used in low- or medium-enthalpy geothermal sources, where resource fluid is heated in a closed loop by process fluid, increasing market demand.

Flash cycle power plants are the most frequent type of geothermal power facilities. They employ high-temperature geothermal water from a depressurized reservoir or "flashed" to generate steam. This steam is then utilized to power turbines, which produce electricity.

By Application

The market can be bifurcated by application into Industrial, Residential, and Agricultural. Industrial application is the most common application in the market. Geothermal energy is used in various industrial applications, such as direct heat utilization in manufacturing processes, space heating, and cooling. Geothermal energy is frequently used for process heating and other thermal needs in food processing, manufacturing, and mining industries. Geothermal heating can meet the heating needs of certain companies as long as they do not require exceptionally high temperatures. Geothermal heating has the potential to replace fossil fuels while also providing continuous industrial output.

Geothermal energy can heat, chill, and supply hot water to homes. Residential geothermal heat pump systems are becoming increasingly popular for residential space conditioning. They exploit the Earth's constant temperature to provide efficient heating in the winter and cooling in the summer.
