Eren Groupe
Eren Groupe’s expertise is built around three core transversal fields
Renewable energy productionProducing electricity from renewable energies such as wind and solar is one of the main keys to meet the inevitable growth in electricity consumption and a major climate crisis.

STEP 1Renewable energy production
Producing electricity from renewable energies such as wind and solar is one of the main keys to meet the inevitable growth in electricity consumption and a major climate crisis. But other technologies, other sources and other innovative solutions will be needed, and that's also what EREN Groupe is currently working on..
This is why EREN Groupe is developing wind and solar power plants, as well as a wide range of other renewable energies. For example, the aim is to produce hydrogen by developing power plants of several thousand megawatts in areas with exceptional wind or solar deposits, or, in smaller quantities but close to consumption areas, by pyro-gasification of biomass. The Group supports the development of a new generation of nuclear power, with smaller reactors that enable the nuclear fuel cycle to be closed. Finally, it produces renewable energy by recovering waste heat, that would otherwise be lost, from industrial processes or from the heating or cooling of buildings.
STEP 2Energy savings
Even before decarbonizing the energy we are already using, the best way to reduce CO2 emissions is to save it... Decarbonizing the energy we are currently consuming is in itself a complex objective. However, our energy consumption is set to increase as a result of numerous factors, including the growing use of electricity as well as the rising demographics and standard of living of the world's population. It is therefore crucial to seek to reduce our energy consumption wherever possible.
EREN Groupe is therefore developing technologies to optimize building's energy consumption (Accenta, Esmé Solutions), using software to control a large number of factors: thermal inertia, occupancy rate, cardinal orientation, weather forecasts, etc. Similarly, the Group is developing technologies to reduce the energy bills of critical cooling systems (BeeBryte), which are particularly energy-intensive. In addition to this direct consumption, EREN Groupe has also invested in technologies such as OSMOS Sensors, which extend the lifespan of civil engineering structures (bridges, buildings, etc.) and this reduce the periodic use of carbon-based materials and energy for their construction.
STEP 3Energy storage
The development of renewable energies, which are often intermittent but also sometimes overabundant, requires the ability to store these energies and explains the rapid development of chemical batteries. Through geothermal storage technologies as well as the use of phase-change materials, EREN Groupe is working, amongst other things, on creating thermal batteries capable of storing both cold and heat.
These storage methods have the advantage of not requiring the use of rare metals. Furthermore, since a large proportion of the energy consumption is linked to the production of heat and cold, thermal batteries are very well suited to a majority of uses. To design these batteries, EREN Groupe has put together a wide range of innovative thermodynamic solutions, to store large quantities of cold (Fafco's Icebats) or heat (ceramics developed by Stolect), but also to store the surplus cold or heat from tertiary and industrial buildings from one season to the next (Accenta).
