Who are we
Pioneer of a carbon-neutral future
We are pioneers in a transformative shift that initially impacts the use of fossil fuels in industrial steam production and gradually expands towards more diverse applications. We will be a significant part of the electricity grid’s demand response capacity. We provide an opportunity for the continuous growth of renewable energy sources by creating flexibility in the power grid
Our story
From Research to Operational Company
Our story began in 2016 when Professor Jero Ahola, an energy efficiency professor at LUT University, and serial entrepreneur Ari Piispanen from Lappeenranta explored alternative solutions for energy storage.
The prices of electrochemical batteries are too high for economically viable storage, and the required raw materials are rare and expensive. Industrial steam production relies heavily on fossil fuels, making steam production currently more expensive than electricity production.
As a result of the research, Elstor Oy, a company focusing on thermal energy storage, was founded in July 2017. The development of the energy storage has been ongoing since then and continues. Our current storage solution, proven to be operational in industrial use, has been in operation since 2021.
The experiences with our equipment have been positive. Through the first pilots and commercial implementations, we have evolved the device into its current form – functional, profitable, and sustainable.
