HEVATECH is a research and development company for sustainable and innovative energy solutions
based on heat accumulation.

The accumulation of energy is a greater challenge in future energy scenarios. To adapt supply to demand, storage is an essential step to optimize resources at central or local level. Storage is also essential to accompany the growth of renewable energy whose main defect is discontinuity.

  • It develops a solution for thermal energy conservation based on thermodynamics, i.e. the ability of some products to "store heat" during a chemical transformation, and then return it during an inverse transformation.

  • It develops a range of products and associated technological solutions, to select a return temperature in a wide range from 40 ° C to 450 ° C. This opens up a vast field of applications ranging from domestic heating to turbo power alternators for power generation. The selected products are safe products that are not harmful to the environment.   Visita il sito dell'azienda HEVATECH

Hevatech technology

To convert heat into electricity, HEVATECH proposes an innovative and economically competitive solution with its proprietary process TURBOSOL, currently with a power range of 20 to 100 kWe, soon to be increased to 500 kWe.

HEVATECH targets waste incineration and biomass markets, industry and large generators. It focuses on Europe and countries with high electricity prices.

In 2020, the European market for waste heat recovery technologies in the same power range will represent over € 4 billion.

Waste incinerators:

  • The European waste incineration market is growing (138 million tonnes in 2012, up to 169 million by 2023 according to Eurostat). One of the ways to recover energy involves producing electricity, which is likely to represent 84% of market shares in 2023.

Biomass incinerators and cogeneration:

  • The potential market for heat recovery technologies covers Europe and the French overseas territories for the biomass market, and only Europe for cogeneration. New installations and replacements have been considered in these two segments.
  • The total reachable biomass market should grow from 1.3 GW in 2010 to 2.8 GW in 2023, with cogeneration moving from 2.9 GW in 2010 to 8.8 GW in 2023.



  • In Europe, waste heat from industry is set to rise from 3 GW in 2015 to over 3.9 GW in 2023. This only concerns industrial applications under 5 MW. These heat sources represented around 2.5 % of resources in 2005 and could reach 7% by 2023.

Generators and engines:

  • The generator market includes diesel generators (most of the equipment in Europe), generators operating with gas/natural gas and other fuels (heavy fuels, biofuels and mixed). HEVATECH only targets equipment operating continuously with a power range of under 5 MW, which represented 5.5 GW of installed capacity in 2012 and should reach 10.8 GW in 2023 in Europe alone.

Market Goals

On the one hand, industrialists have an economic goal of energy optimization; on the other hand, they are confronted with fiscal and environmental issues, in particular CO2 emissions.
Three main areas:

Recovery and remediation

Energy balance

IMG.2 Technologies in comparison

TURBOSOL technology

TURBOSOL technology is based on a combination of 3 concepts :

  • Waste heat is captured by two fluids: a heat-transfer fluid (oil) and a thermodynamic fluid (water/steam).
  • A two-phase accelerator triggers a strong acceleration of the mix during a quasi-isothermal expansion.
  • A Pelton-type impulse turbine is employed, renowned for its robustness and high performance.

Its easy use and robustness give TURBOSOL technology a distinct economic advantage over its competitors:

  • A 4-year return on investment, twice as fast as directly competing ORC solutions.
  • The turnkey target cost for TURBOSOL technology comes to €k 3-3.5 per kWe installed depending on the conditions (exchangers, power, environment, cold source, etc.) for mass production from 2020.
  • A simple, robust, quiet machine that is easy to install and operate (small size, low rotation speed of 1,500 turns/min.)
  • Very low-pressure operation (1-bar turbine, 10-bar circuits)
  • “Free” heat recovery in a broad temperature range (from smoke temperature > 300 °C, up to 100°C)
  • Security, respect for the environment (no pressure, no organic fluid)
  • Modular (several jets on the same turbine) and standardized
  • Potential thermal discharge of up to 100 °C, making it possible to implement the technology in a “hot context” or recovery for associated hot or cold production.
  • No change to the facilities’ environmental classification (ICPE) (confirmed by the Regional Department of Environment, Planning and Housing)
