Hyme Energy, a Danish company, is making significant strides in renewable energy storage by advancing molten salt battery technology. This innovative approach aims to enhance the efficiency and reliability of energy storage, particularly for industrial applications, by utilizing excess renewable energy to heat molten salt for later use.
Key Takeaways
- Hyme Energy’s molten salt technology can store renewable energy for over 10 hours.
- The system achieves efficiencies of up to 90% for industrial heat applications.
- A new 1 GWh molten salt storage system is in development, capable of powering 100,000 homes.
- Collaboration with Sulzer enhances the technology’s commercial viability.
The Concept Behind Molten Salt Energy Storage
Hyme Energy’s approach is a variation of concentrated solar power (CSP), which traditionally uses mirrors to focus sunlight to generate heat. Instead of relying on complex mirror installations, Hyme Energy proposes using excess renewable energy during peak sunlight hours to heat molten salt. This stored energy can then be converted back into steam for industrial use after sunset, addressing the challenge of renewable energy dispatchability.
Advantages of Molten Salt Technology
- Extended Storage Duration: Unlike conventional grid-scale batteries that typically provide power for about four hours, Hyme Energy’s system can store energy for ten hours or more.
- Cost-Effective Solution: The technology offers a competitive alternative for industrial heat electrification, supporting the decarbonization of process heat.
- High Efficiency: The system boasts efficiencies of around 90% for industrial applications, making it a viable option for energy-intensive industries.
Recent Developments and Collaborations
In 2024, Hyme Energy partnered with Swiss fluid engineering specialist Sulzer to create a molten salts (MOSS) demonstrator plant in Esbjerg, Denmark. This facility successfully validated the concept of storing renewable energy in molten salt at temperatures reaching 600°C (1,112°F).
Sulzer’s expertise in molten salt pump development has been instrumental in advancing this technology. The collaboration aims to optimize the system further and establish a robust supply chain for commercial deployment.
Future Prospects
Hyme Energy is currently working on developing a 1 GWh molten salt storage system, which is expected to power approximately 100,000 homes for ten hours. This project highlights the potential of molten salt technology to significantly contribute to the energy transition and decarbonization efforts across various industries.
Additionally, the company is developing what is touted as the world’s largest industrial thermal energy storage system, a 200 MWh facility in Holstebro, Denmark. This project is anticipated to save Arla Foods, a major dairy cooperative, approximately €3 million annually in process heat costs.
Conclusion
Hyme Energy’s advancements in molten salt battery technology represent a promising step forward in renewable energy storage solutions. By harnessing the power of molten salt, the company is not only addressing the challenges of energy dispatchability but also paving the way for a more sustainable and efficient energy future. As the world continues to seek innovative solutions to combat climate change, technologies like those developed by Hyme Energy will play a crucial role in the transition to a greener economy.
