TheStorage secures €3.6M to expand its industrial thermal energy storage solutions

The company aims to tackle one of the most emissions-intensive and difficult sectors to decarbonise: industrial heat production. Its technology stores energy in sand, allowing industrial players to electrify heat processes, integrate renewable energy, and optimise usage based on electricity market prices. This approach can help significantly lower both energy costs and emissions compared to fossil fuel-based systems.

At present, most industrial heat is still produced using fossil fuels. However, the growing availability of renewable energy and fluctuations in fossil fuel prices are increasing the need for more flexible and cost-effective solutions. By storing energy and releasing it when required, TheStorage’s system addresses the intermittent nature of renewables and enables a more stable and economically viable shift toward low-carbon energy.

The new funding gives us real momentum in commercialising our technology. Interest in thermal energy storage is growing enormously across industry, and our goal is to be the number one choice for companies looking for efficient solutions to manage their energy costs and support their sustainability targets,

said Timo Siukkola, CEO and co-founder of TheStorage.

Beyond lowering costs and emissions, the technology allows industrial operators to adapt to changes in electricity prices and take part in grid balancing markets. This opens up new revenue opportunities while also supporting grid stability. The system is built for efficient heat transfer and is designed to integrate smoothly into existing industrial processes without affecting performance.

With the new funding, the company plans to speed up commercialisation, grow its team, and continue improving its technology, with the goal of scaling its solution globally as industries look for practical ways to cut emissions and reduce energy costs.

About TheStorage

TheStorage is a cleantech company focused on developing industrial thermal energy storage solutions to help reduce emissions and energy costs. Its core technology stores energy in materials like sand and releases it as heat when needed, enabling industries to replace fossil fuels with electricity-based heating. By allowing companies to use renewable energy more effectively and manage energy consumption based on electricity prices, TheStorage supports a more flexible and cost-efficient transition to low-carbon industrial processes. The company primarily targets sectors where heat production is energy-intensive and difficult to decarbonise.
