Engie Solutions Hydrogène & Engie Green développe le projet MarHySol afin d’installer une unité de méthanation destinée à produire du méthane de synthèse.
Il sera fabriqué grâce au CO2 fatal extrait d’un méthaniseur existant et de l’hydrogène généré par un électrolyseur de 4 MW, alimenté en électricité par un parc photovoltaïque.
Pour initier ce projet, les équipes Ingérop réalisent les études de faisabilité afin d’alimenter l’étude d’impact nécessaire à la validation de l’implantation des infrastructures.

Following an initial first framework agreement aimed at outsourcing the complete project management for certain overhead line rehabilitation and underground line construction projects, RTE, the operator of France’s electricity transmission network, is once again placing its trust in Ingerop’s teams by awarding them two new framework agreements:

• research and processing of declarations of public utility and agreements for HTB1 overhead lines, in partnership with SEGAT (subcontractor),
• complete outsourcing of project management for the construction or extension of certain Very High Voltage substations. Our mission notably includes civil engineering, high voltage/low voltage studies, and telecommunications networks.

This ambitious programme enables us to support RTE in the development and modernisation of its power grid for at least the next three years.

Le projet du Val’Tram consiste à prolonger la ligne T du tramway d’Aubagne sur près de 14 km jusqu’à la commune de La Bouilladisse. Le tracé réutilise en grande partie l’emprise de l’ancienne voie ferrée dite « voie de Valdonne » et parcourt cinq communes (du Nord vers le Sud) : La Bouilladisse, La Destrousse, Auriol, Roquevaire et Aubagne. Le tracé étant en majeure partie en voie unique, les 11 nouvelles stations sont principalement conçues en voie double afin de permettre le croisement des tramways.
Pour parfaire le projet qui vise à réduire le trafic sur la zone, deux parkings relais et deux poches de stationnement seront créés.

The redevelopment of the Paris Issy-les-Moulineaux heliport is intended to reduce the amount of land in the City of Paris occupied by Aéroports de Paris (ADP). This will enable the extension of the Suzanne Lenglen Park, in particular.
The first phase of works, which was completed at the end of 2025, involved reducing the footprint of the FATO (Final Approach and Take-Off) area, installing new markings and fencing, and freeing up two areas totalling 2.5 hectares.
The second phase involves constructing three buildings (an office building, a helicopter hangar and a helipad), creating helicopter parking areas and building the associated roadways.

The Ring des Ulis is one of the largest road junctions in the Essonne region. Notably, it provides access to the Courtaboeuf business park, which is one of the main economic hubs in the Île-de-France region.
The existing junction has been completely redeveloped to improve access to the business park, enhance user safety, and optimise traffic flow between the various lanes. To this end, new infrastructure has been created for the interchange with the RN118, thereby reserving the Ring for local traffic.
This involved constructing a new engineering structure to cross the RN118, as well as creating five slip roads and removing the old ones, all while maintaining traffic on the existing infrastructure.

The Toulouse metropolitan authority has undertaken the transformation of the Garonne’s banks, quays and islands (Ramier) by developing the Grand Parc Garonne project. This landscaped area comprises leisure spaces and a soft mobility route along the river.
As part of the project to reconnect the city with nature, the consortium comprising Eiffage, Ingerop, Grimshaw, PPA and Quartiers Lumières won the competition to design the Robert Poujade footbridge. The bridge is located between the embankment and the ‘Rapas’ alley on the left bank, opposite the new Ile du Ramier park.
The five-metre-wide, cable-stayed footbridge has a main span of 165 metres and is complemented by a 158-metre-long access ramp. The 60-metre-high, inclined metal pylon supports the cable stays of the central span and the retaining cable stays.

Voltix, a subsidiary of the VINCI Group, is developing its own network of charging stations for electric heavy goods vehicles (HGV). The company plans to deploy around fifty stations on priority routes and in major logistics hubs by 2028. These hubs will be equipped with megawatt fast-charging systems (MCS), which are charging stations with a capacity ranging from 350 kW to 1 MW.
They will also have a photovoltaic canopy and an access control system with number plate recognition.
The teams from Ingerop are responsible for project management of the design of an initial charging station located in the Vienne department, including civil engineering, structural engineering, external works, electrical engineering and environmental aspects.
An active environmental approach is being pursued to meet regulatory requirements and the VINCI Group’s environmental objectives for 2030.

Spark Cleantech is a start-up founded by the CNRS and CentraleSupélec that is developing a methane plasmalysis process.
This process will enable the production of low-carbon hydrogen from cost-effective, locally sourced natural gas, while recovering clean solid carbon. This approach will facilitate large-scale decarbonisation of the industry without putting additional strain on the electricity grid.
Ingerop is supporting Spark Cleantech in the design of the pilot plant by providing project management assistance services.
Preliminary design studies:

• design of the process flow diagramme, selection of equipment technologies, 2D/3D drawings
• pre-consultations with process equipment suppliers: drafting of process datasheets, consultation and evaluation of tenders, technical and commercial recommendations, comparison of
  capital expenditure(s)
• recommendations on the equipment operating ranges.
• ATEX compliance support, risk analysis.

France is entering a new era in civil nuclear energy with its EPR2 plan, which involves building six new reactors at three sites.
Ingerop and its subsidiaries, including Actierra, are supporting the design and construction of the Operational Support Centres (OSC).
Over 100 of the Group’s ISO 19443-certified nuclear infrastructure engineers and technicians will be deployed to fulfil two project management roles:
a design and construction contract with Eiffage Construction
Normandie, in collaboration with the architectural firm ATAUB,
for the Penly OSC.
A project management contract for the Gravelines and Bugey
OSCs, acting on behalf of EDF.
Ingerop’s expertise in soil analysis and designing resilient infrastructure in response to local climatic and geotechnical conditions will enable it to meet the high safety, ecological, sustainable and comfort standards required.

Founded in 2024 by Frédéric Varaine and selected for the France 2030 call for projects by the Banque Publique d’Investissement, Otrera originated from the CEA and brings together French expertise in fast neutron reactors. The company is developing a next-generation small nuclear reactor capable of producing lowcarbon electricity and heat at a competitive and optimised cost.
To support it in carrying out the preliminary design studies for its first reactor, Otrera One (200 MWth – 80 MWe), the start-up called on Ingerop.
The challenge to obtain the necessary permits first time they are applied for application is crucial. Our mission is to be a preferred partner capable of combining design excellence, regulatory rigour, agility and adherence to deadlines and cost targets.

Against the backdrop of an unstable global political landscape, France and the European Union are prioritising the strengthening of the defence industry to ensure security and sovereignty. To support this strategy, our experts in munitions production, infrastructure hosting systems, nuclear deterrence and naval and aerospace engineering provide innovative and reliable solutions to companies in the defence industrial and technological base (DITB).
Our international presence also enables us to support these companies wherever their export contracts require infrastructure to be constructed, optimised or secured.

Kerat’Innov is a producer of high-quality keratin for the nutraceutical(food supplement) and cosmetics industries. As part of its development, particularly at an international level, the company intends to expand production at its La Ciotat site.
The support provided for this project is a prime example of the expertise our Group has to offer. The teams from Deltaèdre, Ingerop Life Sciences and Ingerop are working together to deliver an expanded EPCM project management assignment, including project management, pharmaceutical feasibility studies, design and regulatory affairs, processes, commissioning, start-up and consultancy, within an extremely tight 18-month timeframe.
