The Sand Battery saves thousands of tons in GHG emissions annually, with zero toxic or harmful substances released.

Profitable

Our solution provides a 15–40% return on investment compared to traditional heat production methods. 

Reliable

Our Sand Battery ensures high security of supply with fast, automatic activation.

Industries

Food & Beverage

The Food and Beverage industry relies on precise temperature control for processes like pasteurization, sterilization, and drying.

By switching to the Sand Battery, you can achieve stable heat supply for these processes without relying on fossil fuels, lowering both operational costs and carbon emissions. The Sand Battery’s ability to supply heat ranging 60 to 400 °C makes it ideal for diverse thermal applications in food production, improving energy efficiency and reducing dependency on volatile fuel markets.

Pulp & Paper

Pulp and Paper production requires a significant amount of heat for drying, pulping, and chemical recovery processes.

The Sand Battery provides a sustainable and efficient heat source that can replace combustion-based systems, offering high-temperature heat for drying and pulping while reducing greenhouse gas emissions. It helps lower energy costs and increase sustainable development in an energy-intensive industry.

Textiles & Clothing

Textiles and Clothing production involve energy-intensive processes like dyeing, washing, and drying, which require large amounts of heat.

With the Sand Battery, textile manufacturers can store and supply clean, consistent heat, enhancing operational efficiency while minimizing the carbon footprint of their high-heat processes. Our solution can also help lower energy costs and improve regulatory compliance in sustainable fashion production.

Metal, Mining & Minerals

Metals, Mining, and Mineral industries demand extreme temperatures for smelting, refining, and sintering processes.

The Sand Battery can provide heat up to 400°C, offering a renewable alternative to combustion for lower-temperature processes like drying and preheating, reducing emissions in mineral processing. Its robust design is ideal for supporting energy-demanding sectors, reducing reliance on fossil fuels, and enabling better integration with renewable energy sources.

Chemicals & Pharmaceuticals

Chemical and Pharmaceutical manufacturing requires precise thermal management for processes like distillation, crystallization, and chemical reactions.

The Sand Battery delivers reliable and emission-free heat for these processes, ensuring energy efficiency and reducing carbon emissions. By decarbonizing thermal energy storage, companies in this sector can lower their costs and meet increasingly stringent environmental regulations.

Manufacturing

Manufacturing sectors ranging from the automotive industry to electronics need substantial thermal energy for processes like drying, molding, and curing.

The Sand Battery provides a clean and cost-efficient source of heat that can decarbonize energy-intensive manufacturing processes. With customizable temperature ranges, it helps manufacturers reduce their operational costs and carbon footprints while ensuring process stability and efficiency.

Other Process Industries

Other process industries such as glass, ceramics, and plastics require consistent and high-temperature heat for production.  

The Sand Battery offers a flexible thermal energy solution that can replace fossil-fuel-based systems, providing stable, clean heat for high-temperature processes. This enables industries to reduce emissions, lower energy costs, and contribute to a circular economy by integrating renewable energy into their thermal processes.
