It also tracks historical and forecasted market growth across various geographies.

The geothermal electricity market size has grown rapidly in recent years. It will grow from $8.29 billion in 2024 to $9.23 billion in 2025 at a compound annual growth rate (CAGR) of 11.3%. The growth in the historic period can be attributed to resource availability, environmental concerns, government incentives, energy security.

The geothermal electricity market size is expected to see rapid growth in the next few years. It will grow to $13.93 billion in 2029 at a compound annual growth rate (CAGR) of 10.8%. The growth in the forecast period can be attributed to climate goals, energy transition, market liberalization, global expansion. Major trends in the forecast period include technological advancements, increasing deployment of enhanced geothermal systems (egs), hybridization with other energy sources, geothermal heat pumps, direct use applications.

The escalating global need for electricity is anticipated to be the driving force behind the geothermal electricity market in the upcoming forecast period. Factors such as expanding economies, rapidly growing populations, and heightened transportation demands, particularly in developing nations like China, India, Brazil, and certain African countries, are significantly contributing to the surge in electricity demand. Projections indicate a substantial increase in global electricity demand, estimated to reach 38,700 Terawatt-hours (TWH) by 2050, with electric vehicles expected to represent around 9% of this demand. As the global population is forecasted to increase by approximately two billion in the next two decades, a corresponding 49% surge in electricity generation is expected by 2040. Consequently, the mounting requirement for electricity is foreseen to steer the growth of the geothermal electricity market.

The upward trajectory in the utilization of heat pumps within the commercial sector is poised to propel the expansion of the geothermal electricity market in the foreseeable future. Commercial heat pumps, integral components of heating, ventilation, and air conditioning (HVAC) systems tailored for non-residential and commercial setups, rely on thermal electricity to facilitate the heat exchange process. This process enables the extraction or release of heat from the surrounding environment, thereby effectively delivering heating or cooling solutions for residential, commercial, or industrial applications. For instance, statistics from March 2023 published by the International Energy Agency (IEA) highlighted an 11% growth in global heat pump sales in 2022, marking a second consecutive year of double-digit expansion, primarily attributed to increased policy backing and incentives. Notably, in Europe, heat pump sales experienced exceptional growth, reaching nearly 40%. Consequently, the escalating utilization of heat pumps in the commercial sphere is a significant driver in the advancement of the geothermal electricity market.

Globally, the geothermal electricity market is experiencing substantial financial backing from governments. This support is in the form of grants and other incentives aimed at fostering sustainable energy sources. An illustrative instance is the Geothermal Energy from Oil and Gas Demonstrated Engineering Funding Opportunity (FOA), announced in 2022 by the U.S. Department of Energy (DOE). The initiative is set to allocate up to $165 million to expand the deployment of geothermal energy in the United States, utilizing technologies and expertise from the oil and gas sector. The initial FOA plans to earmark $10 million for the establishment of a consortium, envisaged to devise a roadmap addressing technological and knowledge gaps in geothermal energy. Subsequently, leveraging this roadmap, the U.S. Department of Energy (DOE) plans to allocate an additional $155 million for research purposes aimed at filling these identified gaps.

Enterprises within the geothermal electricity sector are investing in innovative technologies to make geothermal energy more accessible for electricity generation and heating purposes. Presently, significant geothermal energy extraction occurs in areas abundant in easily accessible, high-temperature water. Yet, regions like the UK and France possess limited availability of such resources compared to volcanic regions like Iceland and Indonesia. Consequently, companies are channeling investments into novel methodologies to enhance the extractability and accessibility of geothermal energy. An example is Climeon, a Sweden-based company that developed technology functioning within temperature ranges of 70 °C to 120 °C. This innovation utilizes temperature differentials between hot and cold water to produce electricity, providing a continuous power source unaffected by weather conditions, unlike solar and wind power.

Leading entities operating in the geothermal electricity market are embracing strategic partnerships to fortify their capabilities and competitive positioning. Strategic partnerships involve a collaborative process wherein companies leverage each other's strengths and resources for mutual benefit and success. In March 2023, Geothermal Core Inc., a US-based geothermal exploration and production power company, partnered with GEG ehf, an Iceland-based geothermal developer and EPC company. Their joint objective is to establish a utility-scale geothermal power plant in Texas, emphasizing the production of clean baseload electricity for sustainable energy purposes.

Geothermal electricity involves generating power by harnessing the Earth's internal heat. This renewable energy source utilizes steam or hot water from geothermal reservoirs beneath the Earth's surface to drive turbines connected to electricity generators. Geothermal electricity is a sustainable and environmentally friendly energy option, offering a reliable power supply with a low carbon footprint. It is used in a variety of applications, from residential heating to large-scale power plants.

The geothermal electricity market, as outlined in this report, is categorized into various types, including back pressure, binary, double flash, dry steam, single flash, and triple flash systems. Additionally, it is further divided by end-users, encompassing dry steam power stations, flash steam power stations, and binary cycle power stations.
