According to the U.S. Geological Survey, Hydrofluoric acid is still the primary input for the vast majority of fluorine-containing compounds, and is widely used in Texas and Louisiana. Solvay has three large hubs spread globally, dedicated to the growth of anhydrous hydrogen fluoride. The U.S. Geological Survey 2023 data continue to underscore the strategic value of acid-grade fluorspar in the U.S. industrial consumption, supporting anhydrous hydrogen fluoride market studies and supply chain reliability.

Market Dynamics:

Drivers:

• Petrochemical Refinery Upgrades Amplify Acid-Grade Anhydrous Hydrogen Fluoride Consumption

Worldwide refinery modernizations to meet tighter sulfur regulations for low-sulfur fuels are raising demand for the acid-grade anhydrous hydrogen fluoride needed in alkylation units. Five large U.S. refineries have undertaken alkylation unit upgrades in 2023 and are projected to consume about 8% more hydrofluoric acid than they did in 2022, the U.S. Energy Information Administration said. These installations make it possible to produce higher-octane gasoline, with the added benefit of reducing olefins, and contribute to securing the position of hydrofluoric acid as an essential catalyst. Major petrochemical companies, such as ExxonMobil and Shell have announced multi-year hydrogen fluoride contracts to 2027. This further underlines a robust anhydrous hydrogen fluoride market share and long-term demand. This trend further reinforces the overall anhydrous hydrogen fluoride market size and indicates the need for strong anhydrous hydrogen fluoride market analysis.

• Expansion of Semiconductor Fabrication Centers Drives High-purity Anhydrous Hydrogen Fluoride Demand

The presence of wafer fabrication plants in North America and Asia is driving substantial consumption of high-purity anhydrous hydrogen fluoride (AHF) in silicon wafer etching and chamber cleaning. To back up this demand, Thiele said the USGS had observed a 12% year-on-year increase in the use of acid-grade fluorspar feedstock in 2023, due to a 20% rise in global semiconductor etching capacity. Top anhydrous hydrogen fluoride firms, such as Solvay and DuPont, have answered with new purification systems providing sub-5 ppm hydrogen fluoride purity to satisfy stringent semiconductor needs. This is a result of very strong growth in the anhydrous hydrogen fluoride market and suggests the necessity of focused and dedicated anhydrous hydrogen fluoride market research to assist investment decisions in the anhydrous hydrogen fluoride sector.

Restraints:

• Safety concerns and handling complexities hinder the wider adoption of anhydrous hydrofluoric acid

Anhydrous hydrofluoric acid is deadly and burns through everything, necessitating significant safety measures too expensive for some smaller chemical companies to implement. In 2022, the National Institute for Occupational Safety and Health identified more than 120 incidents of hydrofluoric acid exposure in the workplace. OSHA, in turn, responded by enacting more stringent safety requirements, including enhanced personal protective equipment and specialized operator training. These steps are not only arduous, but they are also expensive, about USD 250,000 per facility, creating obstacles to entry for new or cash-strapped companies. This has led to companies within the developing regions not wanting to be early adopters of hydrogen fluoride-based processes despite the potential technical benefits, and thus restricting the taking of anhydrous hydrogen fluoride market share in many regions globally.
