Feedback on our H2P solution at the GRDF/NaTran webinar

On Tuesday 17 June, Hevatech had the honour of presenting, alongside Michel Luong from MERSEN Gennevilliers, concrete feedback on our H2P solution during the GRDF/NaTran webinar on decarbonisation and industrial competitiveness.

The presentation covered the design and installation by Hevatech of an H2P (Heat to Power) solution for the MERSEN site in Gennevilliers, a company specialising in advanced materials.
This project demonstrates the effectiveness of our approach, with remarkable results :

  • 200 tonnes of CO₂ avoided every year ;
  • 15% of the site's heating needs covered ;
  • 7% of the waste heat deposit converted into electricity ;
  • An estimated return on investment of 3 years, excluding subsidies ;
  • Environmental and economic performance ;

This installation is a perfect example of how the recovery of waste heat can combine environmental performance and economic profitability. It is part of a concrete and measurable industrial energy transition. Hevatech would like to thank Laurent Lantoine from GRDF for this invitation and congratulate all the teams involved in this technical and environmental achievement.

Participation in the National Eco-Enterprise Forum at the Ministry of the Economy !

On Thursday 3 April 2025, Hevatech and France Cleantech Industries (FCI) will be taking part in the Forum National des Éco-entreprises at the French Ministry of the Economy, with a clear ambition :

Demonstrate that economic performance and emissions reductions can go hand in hand.

This strategic meeting will address crucial issues such as decarbonisation without compromising competitiveness, full financing of projects up to 100%, optimising the use of waste heat, and the sharing of practical experience in the field.

Convinced that sustainable solutions must be efficient, cost-effective and immediately operational, we are working to help manufacturers accelerate their ecological transition.

In this emblematic venue, our team looks forward to meeting you for constructive discussions in the service of a shared vision: accelerating our country's energy and industrial transition.

Hevatech Launches MAEVA : The First Offer Dedicated to Industrial Waste Heat Characterization

MAEVA - Measure, Audit and Study of Energy VAlorisation is an innovative offer dedicated to the characterisation of industrial waste heat.

This waste heat, which is often overlooked, offers significant potential for improving competitiveness and reducing carbon emissions.

MAEVA enables this heat to be accurately characterised by analysing existing data and carrying out on-site measurements. This solution is based on minimally intrusive measurement tools, remote monitoring and in-depth financial analysis. MAEVA enables industrial companies to maximise the use of waste heat to optimise their energy consumption.

A complete study in 5 stages :

  1. Analysis of existing data and acquisition of new measurements ;
  2. Statistical processing and precise quantification of recoverable heat ;
  3. Analysis of suitable solutions: cogeneration, heat/cold production, etc. ;
  4. Architecture optimisation and equipment sizing ;
  5. Evaluation of costs (CAPEX/OPEX), calculation of ROI and search for financial assistance ;

Participation in the Industry & Ecological Transition Commission Evening

Tuesday 4 March 2025, during the Industry & Ecological Transition Commission Evening organized by France Invest, a roundtable discussion addressed the challenges of the energy transition. Patrick Bouchard, president of HEVATECH, participated in the conversation moderated by Sophie Paturle Guesnerot, with influential speakers such as Antoine Huard (Verso Energy), David Marchal (ADEME), and Julia Reinaud (Breakthrough Energy).

The event highlighted the importance of energy efficiency and the valorization of waste heat as a key lever to accelerate the transition. However, several obstacles remain, such as insufficient knowledge of these waste heat sources and concerns about the impacts on existing industrial processes. Investors also face difficulties in financing, particularly in the intermediate phase.

To overcome these obstacles, Patrick Bouchard proposed simplifying existing support mechanisms and creating an assurance system, such as an “energy savings guarantee,” to reassure industrials about early-stage demonstrators.

The energy transition must no longer be a matter of intent, but of action. Additional solutions are needed to make this planning a tangible reality, and reflections are encouraged to move toward a sustainable energy future.

Hevatech : At the Heart of Innovation for a More Sustainable Industrial Process !

Hevatech warmly congratulates Essity for its latest milestone towards zero industrial waste at its site in Hondouville (27)! This significant initiative is supported by ADEME and NextGenerationEU, and we are proud to contribute to this innovative project by sharing our expertise in energy recovery and industrial efficiency.

Thanks to H2P technology, an innovative demonstrator has been implemented to transform recycled paper production residues into several valuable resources :

  • A mineral that can be used by the cement industry ;
  • An energy source for the site ;
  • Electricity and hot air required for paper drying ;

This achievement marks a key step towards a more circular and low-carbon industrial model, fully aligned with the objectives of France 2030.

A big congratulations to all the teams involved in this sustainable transformation !

HEVATECH & ENOGIA, specialists in waste heat recovery and conversion, join forces to conquer new markets in France and International

The aim of this merger is to combine the two Groups' commercial and industrial expertise to sell innovative decarbonization solutions, better meet customer needs, and increase their market presence in France and abroad.

This partnership is based on a strategy of cross-promotion and the pooling of sales networks. The two groups are committed to promoting each other's technological solutions to their customers and partners, by fostering the complementary nature of their offerings. They intend to multiply growth opportunities while consolidating their positions in France and internationally.

While the partnership is primarily commercial, it is also based on technological synergies. On the one hand, ENOGIA specializes in the conversion of low-temperature heat (80 to 200°C) into electricity, thanks to its compact, innovative ORC machines. On the other, HEVATECH is an expert in higher temperatures, from 200°C with its TURBOSOL two-phase turbine technology, and up to 1000°C with its H2P hot-air engine technology, both of which are highly efficient, particularly in cogeneration (heat and power). These complementary solutions enable the two companies to meet a broader spectrum of energy needs, making them even more attractive to customers.

Together, ENOGIA and HEVATECH are leveraging their know-how, networks and technologies to meet the challenges of the energy transition, while pursuing their commercial ambitions in new markets.

AID validation of the SUN2P project and commercial opportunity to recover intermittent waste heat

Hevatech has just obtained validation of the final milestone of its SUN2P project funded by AID (Agence Innovation Défense). The project involves combining an H2P machine with an Eco-Tech Ceram thermal storage system, using heat intermittently supplied by a solar concentrator.

AID's objective in this project was to demonstrate the relevance of a solution for producing electricity continuously 24/7, from intermittent solar energy, but without the need for conventional batteries (sovereignty issue and reduction of battery pollution).

The combination of a hot-air engine and thermal storage has been demonstrated. This result means that Hevatech can now pass on to its industrial customers the solutions developed in this project with its partner Eco-Tech Ceram.

For Hevatech, this represents an opportunity to address intermittent (i.e. non-continuous) sources of waste heat in order to generate electricity on a continuous basis - a whole new area of the market ! Indeed, it is estimated that 29% of waste heat above 300°C in Europe is intermittent, i.e. 22 TWh of the 75 TWh forecast for 2023.

 

     

 

See you at ENLIT in Milan !
