High-Temperature Molten Salt Energy Storage for Industrial Decarbonization

energyPilotedTRL 6

Imagine a giant thermos that can hold heat for a long time using special salts. This system captures extra energy as heat and saves it for when it's needed most. By using a specific chemical trick to stop the salt from eating through the metal tanks, the system lasts longer and costs less.

The business problem

What needed solving

Energy-intensive industries struggle to decarbonize because renewable energy is intermittent and existing thermal storage is often too expensive, bulky, or corrosive to be practical.

The solution

What was built

A thermal energy storage system using hydroxide salts, including a patented corrosion control method and industrial-grade oxoacidity sensors for remote monitoring.

Heavy Industry
enterprise
Target: Energy-intensive industrial plants

If you are a factory operator dealing with high carbon emissions in heat-heavy processes — this project developed a thermal energy storage system that helps decarbonize operations using high-temperature heat.

Food & Beverage
enterprise
Target: Large scale dairy or food processing plants

If you are a food producer like Arla dealing with high energy costs — this project developed a cost-efficient thermal storage solution to stabilize energy use and reduce carbon footprints.

Frequently asked

Quick answers

How does this impact the total installation cost?

The project activities focus on achieving a 70% total installed cost (TIC) reduction through technology development and component design optimization.

Can this be deployed at an industrial scale?

Yes, the system is designed to be scalable and compact, utilizing a design proven for over 20 years in the concentrated solar power industry.

What intellectual property protects this technology?

The system is built around a patented method for adjusting oxoacidity to limit and control corrosion of hydroxide salts on structural materials.

How is the system monitored for safety and maintenance?

The project is industrializing oxoacidity sensors and developing feedback mechanisms for remote monitoring and predictive maintenance.

What is the current commercial progress?

Based on available project data, Hyme has progressed its first commercial project with Arla and submitted an application to the EU Innovation Fund.

Consortium

Who built it

The project is led by a single Danish SME, Hyme Storage ApS, which operates as a spin-off from Seaborg ApS. With a lean 1-partner structure and 35 FTEs, the consortium is 100% industry-driven, focusing on rapid commercialization and industrialization rather than academic research.
