Tampere-based startup TheStorage secured €1 million in funding from 2C Ventures and Superhero Capital to develop its sand-based thermal energy storage technology, which aims to decarbonize industrial heat. The company’s system stores renewable energy as heat, enabling a stable supply of fossil-free industrial heat, even during periods when renewable energy generation is low. The funding will be used to construct a proof-of-concept system, which will be tested with industrial customers to demonstrate its ability to meet various heat requirements, supporting the transition to cleaner energy in the industrial sector.
The industrial sector as a whole consumes about 40% of global energy, significantly more than sectors like transport or building-related energy consumption. Over half of the energy consumed by industry is used for heat production, which is essential for various manufacturing processes, from producing food to making steel. 75% of this heat is generated by burning fossil fuels. Electrifying industrial heat and transitioning to renewable energy requires cost-effective energy storage solutions, as industry needs stable heat energy even when the wind isn’t blowing, and the sun isn’t shining.
The company’s sand-based thermal energy storage technology provides a highly scalable, cost-efficient, and fossil-free solution for industrial heat, delivering substantial reductions in greenhouse gas emissions while also offering significant cost savings. These savings are achieved by allowing customers to harness abundant, low-cost renewable energy—such as wind and solar—when it is plentiful and inexpensive, storing it as heat. This stored energy can then be converted into a stable, continuous supply of industrial heat, reducing reliance on traditional fossil fuels and lowering overall energy costs.
“Currently, majority of industrial heat is produced via burning fossil fuels. Our solution empowers industries to transition to fossil-free processes. Not only will the technology allow industries to reduce their carbon footprint, it will also lead to direct cost savings as the companies utilize renewable energy when it is cheap. The larger the energy storage capacity, the greater the cost-saving benefits,” says Timo Siukkola, Co-Founder & CEO of TheStorage.
Investors recognize industrial heat as acritical challenge, as it accounts for 30% of global greenhouse gas emissions. The growth of renewable energy presents a timely opportunity to address this issue. Electrifying industrial heat is not only technologically viable but also economically and environmentally imperative. The global shift to renewable energy offers a unique opportunity to transform industrial energy systems, aligning them with the goals of emission reduction, cost efficiency, and enhanced energy security.
Hendrik Reimand, partner at the venture capital fund 2C Ventures, believes that the technology could play a critical role in addressing one of the largest challenges in green transition.
“The production of industrial heat is an often overlooked vertical that accounts for an outsized share of global emissions. The technology developed by TheStorage has the potential to be the missing piece of the puzzle in utilizing renewable energy for decarbonizing the industry while also leading to actual cost savings for the customers,” states Hendrik Reimand, Partner at 2C Ventures.
“From the moment we first saw the core fundamentals of TheStorage’s technology, we knew this was a game-changing innovation. For the massive storage capacities required to decarbonize industrial heat and power systems, TheStorage offers an unmatched cost-efficiency that sets it apart from any other solution we’ve seen. We are thrilled to support this team as they scale their breakthrough technology,” comments Jussi Pyörre, Partner at Superhero Capital.
The €1 million investment will enable TheStorage to construct a proof-of-concept system that will be tested in collaboration with several industrial customers at their production sites. This system will demonstrate the technology’s ability to meet diverse industrial heat needs, including pressurized hot water, saturated steam, and thermal oil—using the same base system with easily upgradeable discharging units.
The company envisions large-scale Combined Heat and Power (CHP) storage units capable of supplying both electricity and heat to industrial users and district heating systems. These systems use a steam turbine to convert stored thermal energy into electricity and heat, with electricity from the grid acting as the “fuel.” This electricity heats the storage material, which can later be discharged to produce steam and run the turbine, providing a continuous energy supply.
Unlike fossil fuels, which require complex logistics and handling, electricity flows directly from the grid, simplifying operations and enhancing flexibility in response to fluctuating energy prices. By repurposing steam turbines once powered by fossil fuels, the company enables a transition to fossil-free energy production while making use of existing infrastructure. These units would also contribute to grid stability by providing the inertia needed to maintain frequency control, which renewable energy sources like wind and solar cannot supply.
TheStorage is actively hiring new talent to join its mission of driving the global energy transition. The company is poised to showcase its unique solution to customers, moving from proof of concept to pilot systems, and eventually to full-scale deployment.
