• The Finnish start-up Heliostorage relies on IOTA Tangle for the implementation of its geothermal storage solution.
• Heliostorage technology is already being implemented as part of a Smart Village project in Finland.

According to an article by alykyla.fi, Arctic Smart Village Oy, which is developing sustainable housing, and Holda Energy Solutions Oy, which is developing innovative energy systems, have signed a framework agreement for the design and implementation of a system energy for five Smart Villages in Finland. The first sites are GeoHouse Älykylä in Utajärvi and Mynämäki Älykylä, Finland.

Involved in the implementation, the Finnish technology start-up Heliostorage, which was founded in 2016 and relies on the IOTA Tangle for the implementation of its geothermal storage systems. The idea of ​​Heliostorage is to heat the floor in summer and recover the heat to heat the building in winter with a single water circulation pump.

The controller developed by Heliostorage plays a key role in the solution. As the start-up described, they have managed to replace expensive hardware with software. The control unit performs temperature, flow, energy and power measurements on site and sends the measurements to the cloud where the storage and retrieval algorithms are located. Calculations are performed in the cloud and the results are returned to the controller, which makes the necessary adjustments to the system.

In terms of security and data transfer, IOTA comes into play, as Heliostorage already explained in November 2019 on Reddit:

We chose IOTA and the tangle to provide the connection because of the high security, reliability and authentication services provided by the IOTA tangle . This also allows us to minimize the computing inside the controller, which reduces the cost of the controller unit and the need for on-site maintenance visits, which in turn further improves system economics. .

As Heliostorage commented in a Reddit article published yesterday, the eco-village project of Utajärvi aims to create an energy autonomous village where excess energy is used to recharge electric vehicles. The role of the start-up is to store thermal energy. In addition, the Arctic Smart Village will also develop and test the use of IOTA for micro-payments, in addition to data transfer:

In our current solution, we use IOTA for the transfer of IOT data between our controller and the cloud server. In this Utajärvi project, we are evaluating to extend the use of IOTA in order to also cover micro-payments for thermal and photoelectric energy. The project is at the LOI stage, so no fixed plan exists yet, just ideas and a concept.

We are a technological start-up in renewable energy that loves IOTA , so we are using all possibilities to raise the IOTA flag .

The first Smart Villages is intended to lay the foundations for future cooperation with future projects. As have shown the companies involved, the solution can be replicated to other sites. The framework agreement also applies to export markets, the Älykylä concept having already aroused interest in Europe, Asia and the United States, among others.
