SolidWatts secures Seed round to accelerate industrial heat storage
Pully-based startup SolidWatts has raised €1.9 million (CHF 1.8 million) in Seed funding to advance the development and commercialisation of its high‑temperature industrial heat battery technology. The fresh capital will help the company move from pilot projects to early commercial deployments with energy‑intensive manufacturers.
Tapping into the industrial decarbonisation wave
SolidWatts focuses on storing surplus renewable electricity as high‑temperature heat that can later be used by factories and large facilities. By converting excess power into thermal energy, its systems aim to replace fossil‑fuel boilers and reduce industrial CO₂ emissions, one of the hardest segments to decarbonise.
The startup’s modular heat batteries are designed to integrate with existing industrial processes, supplying reliable heat on demand. This approach targets sectors such as chemicals, food processing and heavy manufacturing, where continuous, high‑grade heat is essential and traditional electrification is often costly or technically challenging.
Funding to drive product development and commercial pilots
The €1.9 million Seed round will be used to refine SolidWatts’ core technology, expand engineering capacity and scale demonstration units into fully bankable commercial systems. The company plans to collaborate closely with industrial partners to validate performance, optimise system design and prove long‑term cost savings.
By combining advances in thermal energy storage, power‑to‑heat conversion and smart controls, SolidWatts aims to offer a flexible alternative to gas and oil-fired systems. The Seed funding marks a key step in positioning the Swiss startup within Europe’s rapidly growing market for industrial energy transition solutions.
As manufacturers across the continent face rising carbon prices and stricter climate regulations, technologies that can deliver affordable, low‑carbon heat are drawing increasing investor attention. SolidWatts’ latest round underlines the momentum behind industrial decarbonisation and the strategic role of advanced heat storage in future energy systems.
