Water Treatment Chemicals Industry Overview
The global water treatment chemicals market specifically for geothermal power was valued at approximately USD 8.84 million in 2023 and is anticipated to grow at a compound annual growth rate (CAGR) of 3.5% from 2024 to 2030. This market expansion is largely driven by the increasing global demand for clean, renewable energy sources. The International Renewable Energy Agency (IRENA) reported that global geothermal electricity capacity rose from 13,196 MW in 2018 to 14,846 MW by 2023. This upward trend emphasizes the rising adoption of geothermal energy as part of the shift toward sustainable energy solutions.
The growing use of scale control agents is also contributing significantly to the market’s growth, as these agents are essential in enhancing the operational efficiency of power generation in geothermal plants. Geothermal power plants are considered environmentally friendly since they produce electricity without burning fuel, releasing 97% fewer sulfur compounds and 99% less carbon dioxide compared to fossil fuel-based plants of similar size. However, geothermal power production involves the use of water that is often saline and contains impurities, requiring thorough filtration before reaching the heat exchanger. Without adequate treatment, the mineral-laden brine can lead to scaling, which hinders performance and can cause costly damage. Water treatment chemicals play a vital role in preventing salts and metals in discharged water from contaminating rivers and lakes, thus protecting surrounding ecosystems.
In geothermal power plants, the water requires treatment due to its rich content of scaling and corrosion-promoting substances, including silica, calcium, potassium, sulfate, hydrogen sulfate, fluoride, magnesium, and chloride. Additionally, geothermal water can contain gases such as carbon dioxide and nitrogen, with traces of ammonia, boron, mercury, and radon. If left untreated, these minerals can cause scaling, which leads to blockages and disrupts power generation. Therefore, geothermal water treatment chemicals are essential to protect these plants from buildup that could interfere with the reliability and continuity of power production.
The range of chemicals used for treating geothermal water includes polyphosphates, azoles, phosphonates, polymaleic acid, and polyacrylate. These compounds help mitigate the risks of scaling and corrosion, ensuring a smooth operational flow. Geothermal power plants utilize naturally heated underground water to produce electricity, providing a renewable energy source that helps meet the global demand for sustainable power solutions.
