We believe that technology can make the world a better place.
When science and engineering comes together, something magical happens.

Today more and more companies start to operate in a more responsible way as we start to understand the importance of the environment and the fact that our very future is at stake. As scientists and engineers we understand that the best solutions for our problems come with practicality. If we can help our clients operate in a more efficient way and save energy, we also help everyone to have a cleaner and better future.

We are going the right direction

The Story

Storing energy is a great challenge for engineers. Spotlight is usually put on storing electricity, however thermal energy storage, i.e. storing heat or cold, is also a key issue for effective energy management.

It is estimated, that 20 billion euros or 250 million metric tons of CO2 equivalent green-house gases could be saved only in Europe with optimal thermal energy storages.

We are a dedicated engineer team with 8 years experience in thermal energy storage. We started as a university research to investigate thermodynamics and the Phase Change Materials.

We made a modelling algorithm, to simulate the processes inside these materials and create more efficient energy storages. Since than we verified our solution with prototypes and pilot projects and now we have many working systems in the national and international market.
We are the proof that everybody can reach his or her dreams with hard work and commitment.

Rita Andrássyné Farkas and Zoli Andrássy during work

Our mission is to find efficient and environmental friendly solution for the arisen problems with thermal energy storage. There are many known solutions even so an engineer can never accept a current, quite-good solution but have to create and develop something new. Our technology is patented, but our research can never end, our goal is to reach better and better scientific results, make the energy systems more efficient and save the environment.
