Outlook for Alkali and Acid Chemical Development in 2025: Green Transition and High-Value-Added Innovation
- Industry Status and Core Drivers
The global chemical market is undergoing structural transformation. Alkalis and acids, as foundational chemical products, are shifting from traditional large-scale production toward greener and higher-value-added solutions. By 2025, China’s soda ash capacity is projected to exceed 13 million tons, with natural soda ash accounting for 35% of total production. Meanwhile, traditional acids such as sulfuric acid and nitric acid face stricter environmental regulations, accelerating the adoption of advanced variants like ultra-pure acids and catalytic acids.
Key Drivers:
Dual-Carbon Goals Driving Innovation: China’s Regulations on the Safety Management of Hazardous Chemicals and the EU’s Green Deal are pushing companies to adopt low-carbon technologies. For example, natural soda ash extraction reduces carbon emissions by 60% compared to the conventional ammonia-soda process.
Emerging Industry Demand: High-purity acids (e.g., electronic-grade sulfuric acid) for new energy vehicles and semiconductors are growing at an annual rate of 12%, while photovoltaic glass production boosts soda ash consumption by 8%.
Geopolitical Reshaping of Supply Chains: U.S. tariffs on Chinese chemicals are accelerating domestic upgrades, such as bio-based citric acid replacing petroleum-derived alternatives.
- Alkali Chemicals: Natural Soda Ash Dominance and Circular Economy Breakthroughs
- Natural Soda Ash Ushers in a New Era
The commissioning of Inner Mongolia Boyuan Group’s 7.8-million-ton/year natural soda ash project in Alxa Tamsag marks China’s transition from synthetic to resource-efficient production. Key advantages include:
Cost Efficiency: Per-ton cost is ¥400–600 lower than the ammonia-soda process.
Environmental Benefits: Water consumption decreases by 70%, with zero ammonia-nitrogen wastewater.
Quality Enhancement: Purity reaches 99.9%, meeting high-end photovoltaic glass standards.
- High-Value Diversification in Caustic Soda
The chlor-alkali industry leverages integrated “alkali-chlorine-hydrogen” production:
Hydrogen fuels energy storage systems for hydrogen refueling stations.
High-concentration caustic soda (50% liquid) replaces imports in PCB etching.
- Technological Frontiers:
CO₂ Mineralization for Soda Ash: Researchers at the Chinese Academy of Sciences synthesize sodium carbonate using industrial exhaust and calcium-based minerals, achieving carbon capture and resource utilization.
- Acid Chemicals: Environmental Upgrades and Functional Innovation
- Green Production Breakthroughs for Traditional Acids
Pyrite-Based Sulfuric Acid: Dual peroxide catalytic oxidation improves purity to 99.99% with 95% wastewater reuse.
Nitric Acid Emission Control: SCR denitrification + molecular sieve adsorption reduces NOx emissions below 50 mg/m³.
- Functional Acids Gain Momentum
Category | Representative Product | Application Field | Technical Highlights |
Superacids | Fluorosulfonic Acid | Lithium Battery Electrolyte | 30% higher thermal stability (>200°C) |
Bio-based Acids | Polylactic Acid (PLA) | Biodegradable Plastics | 25% cost reduction via corn starch fermentation |
Catalytic Acids | SO₄²⁻/ZrO₂ Solid Superacid | Petrochemical Cracking | 50% increase in active site density |
- Emerging Market Demand:
Electronic Chemicals: 12-inch wafer manufacturing requires electronic-grade hydrofluoric acid (purity ≥99.999%), with domestic self-sufficiency rising from 30% (2020) to 65% (2025).
Agricultural Acidifiers: Citric-humic acid composite soil conditioners improve saline-alkali land yields by 15%.
- Strategic Recommendations for the Next Decade
Investment Priorities:
Focus on natural soda ash integrators (e.g., Boyuan Group) and electronic-grade acid producers.
Avoid high-energy synthetic alkali facilities (EU carbon tariffs to rise 15% by 2027).
R&D Directions:
Alkalis: Underground crystallization control, alkali residue-to-refractory material conversion.
Acids: Ionic liquid acid catalysts, microbial synthesis of organic acids.
Policy Coordination:
Establish “alkali-acid-new material” alliances (e.g., soda ash → PV glass → cadmium telluride cells).
Enhance hazardous chemical logistics tracking with IoT-enabled smart storage tanks.
