Energy Solutions
Innovative molten salt energy storage and thermal energy conversion technologies are revolutionizing the energy industry by providing a reliable and efficient means of harnessing renewable energy. These cutting-edge systems utilize molten salts to store heat at high temperatures to produce high-quality, stable steam, which can then be used directly in industrial applications such as food processing, the chemical industry, dyeing and printing, laundry, metalworking, and more, reducing costs while minimizing the impact on the environment. By efficiently capturing and utilizing heat, these technologies not only increase energy storage capacity, but also ensure the stability of the energy supply, even during periods of low sunlight or fluctuating demand. In the global transition to sustainable energy solutions, this technology is a promising pathway to achieving greater energy resilience and reducing dependence on fossil fuel
Our molten salt thermal energy storage (TES) steam generation system offers dual deployment modes — compact distributed units or large-scale centralized plants. A single modular unit currently achieves 1-6MWh daily storage capacity, while modular clusters can scale up to hundreds of megawatts. This scalable architecture supports customized steam output ranging from 1 to 100+ tons per day, seamlessly adapting to diverse industrial energy demands.
Industrial Heating
Here are key advantages of using molten salt thermal energy storage to convert low-cost electricity into heat and generate steam and hot air for industrial needs, presented in English with supporting technical insights:---
1. High Energy Storage Density
Molten salt has a high volumetric heat capacity, enabling large-scale energy storage with compact systems. Its thermal energy density is significantly higher than water or other liquid storage media, making it ideal for industrial-scale applications.
2. Cost-Effective Energy Utilization
By storing low-cost off-peak electricity (e.g., nighttime or renewable surplus) as heat, industries can reduce energy expenses by up to 50% compared to gas-fired boilers. For example, a Beijing steam supply project achieved a 50% cost reduction versus natural gas.
3. Long-Duration Storage (10+ Hours)
Molten salt systems can store heat for over 10 hours daily, ensuring stable steam supply during peak demand periods. This flexibility supports 24/7 industrial operations without interruptions.
4. High-Temperature Steam Output
Molten salt operates at temperatures exceeding 500°C, matching industrial steam requirements (e.g., 1.6MPa, 250°C in textile plants). This ensures compatibility with high-pressure steam turbines and industrial processes.
5. Long Lifespan & Low Maintenance
Molten salt systems have a lifespan of 30+ years with minimal degradation, outperforming electrochemical batteries. Their non-corrosive formulations and stable thermal properties reduce long-term operational costs.
6. Grid Stability & Peak Shaving
By shifting energy use to off-peak periods, molten salt storage reduces grid stress during peak hours. This supports renewable integration and qualifies for grid ancillary services (e.g., frequency regulation).
7. Environmental Sustainability
Replacing fossil fuel-based boilers with molten salt systems cuts CO₂ emissions by ~24,000
8. Flexible Integration with Renewables
Molten salt systems can store surplus solar/wind energy, ensuring continuous steam supply even during renewable intermittency. This is critical for zero-carbon industrial parks, as demonstrated in
9. High Efficiency (Up to 96.3%)
Energy conversion efficiency exceeds 96% in operational projects (e.g., Beijing’s heating system), minimizing losses during heat storage and steam generation.
10. Multi-Scenario Adaptability
Beyond steam supply, molten salt supports combined heat and power (CHP), waste heat recovery, and hybrid energy systems. Its modular design allows scalability for diverse industrial needs.
