HEVATECH is a company specialized in waste heat valorization, installed on 2 manufacturing sites in south-east of France, with test and simulation facilities, and employs a 20 people team.

HEVATECH designs and manufactures its proprietary energy conversion machines, transforming waste heat into electricity and useable clean heat (hot water or high temperature air).

HEVATECH delivers to industrial companies very efficient decarbonization solutions for waste heat sources at minimum temperature of 300°C. Usually conversion efficiency exceeds 70%, thanks to cogeneration (among which 10 to 15% of electricity efficiency), allowing very shorts return on investment. Our main industries applications are metallurgy, forging, casting, glass, paper and special materials manufacturing, waste management (combustion of gases, calcination or pyrolysis of liquids and solids), and power generation.

Our solutions allow waste heat valorization up to 1000°C, using 2 different technologies, based on 2 patented thermodynamic cycles, using heat exchangers with a turbine machine from 300 to 600°C called TURBOSOL, and a piston machine for higher temperature sources called H2P.

We focus on waste heat sources with potential to produce from 10 to 500 kW of electric power after conversion.

Altrans Energies is developing a patent-driven solutions for on-line and global monitoring of transient phenomena in every electrical power networks, especially the undergrounds ones. The objective is to identify the early warning indicators of weaknesses in power grids that would conduct, sooner or later, to power failures and outages.

The innovation consists of several units of transient signal sensors placed on the network and which allow the automatic synchronization-free localization of further faults by exploiting the signal deformation due to propagation (TRANSLOCATOR© technology).

A quantum – inspired artificial intelligence module is implemented at the central data level for the classification of fault sources and to extend the diagnosis by the classification of faults. The software and the AI-driven early detections are the heart of our innovation.

Creating Virtual Power Plants for grid flexibility

Voltalis, an international company founded in France, is the European pionner and leader of automated Demand Response for residential and commercial buildings.
Since 2006, our technology has been optimising energy consumption across Europe. We’re reducing demand on the energy network, the reliance on fossil fuels and lower energy bills for millions of homes and businesses.
We operate in France, Belgium, Spain, France, Finland, Portugal, United Kingdom, Slovenia and Sweden.
Voltalis leverages cutting-edge technology to deliver unparalleled flexibility at scale. Our innovative approach ensures precise, realtime energy management, contributing to a more resilient and adaptable electricity network. This capability enables the electricity network operators to maintain the stability and security homes and businesses spend on, while simultaneously reducing costs and enhancing efficiency.
We offer smart technology which, when installed in properties with electrically controlled devices like heating, cooling, battery storage, and EV chargers, modulates the flow of energy. We optimise the energy consumption of each individual device, communicating the cumulative reductions made with the grid, in real time. When amplified across millions of devices in our network, the resulting financial and environmental savings are transformative.
