What Justy does

Justy is a French engineering and consulting firm founded in 2017 and headquartered in Dijon, specializing in hydrogen ecosystems and renewable energy. The company operates as a small, privately-held SARL with a four-pillar service portfolio: (i) Hydrogen Engineering covering feasibility studies, technical dimensioning, regulatory analysis, and assistance with project authorizations and funding applications to ADEME, FCH JU, and Blending Call programs; (ii) H2 Training Engineering, building territorial training networks to upskill technicians, agents, and engineers for hydrogen-sector roles; (iii) Wind Farm Maintenance Services, including inspection, anti-corrosion treatment, dimensional control, mast cleaning, and sensor/lighting installation for wind operators; and (iv) Strategic Consulting and Project Owner Assistance (AMO), spanning business model design, techno-economic studies, and project development from preliminary design through realization.

The firm serves a dual market: public territories and authorities (regions, metropolises, local agencies such as Vallée Sud Grand Paris, Bourgogne-Franche-Comté, Dijon Métropole, Sipperec, and Semardel) and private enterprises across mobility, energy, and industrial sectors (Keolis, Faurecia, Storengy, Veolia, APRR, MTC). Its geographic reach covers France with documented cross-border operations in Europe including Croatia. Revenue is generated through project-based professional services engagements with no disclosed pricing or recurring contracts.

Justy's operating model is sales-led and relationship-driven, relying on direct business development and a reference-customer portfolio rather than formal marketing channels. The firm has no external institutional investors, no disclosed parent, no subsidiaries, no patents, no certifications, and no AI/ML capabilities embedded in its service offering. The only public-facing management figure identified is Marion Savoy as Director of publication.

Broad incumbents

• Technip Energies: French-headquartered engineering and technology company with a hydrogen and decarbonization offering serving industrial and energy clients worldwide. A potential competitor for large French hydrogen project AMO work, with much greater execution capacity.
• Vestas: Global wind turbine OEM and service provider with a substantial wind operations and maintenance business across Europe. Comparable to Justy's Services Parc Éoliens line but at much larger scale, with full OEM service capability.
• Tractebel (Engie): Large global engineering consultancy with a dedicated hydrogen and decarbonization practice serving industrial, energy and public-sector clients across Europe. Overlaps with Justy on hydrogen feasibility and AMO work but at vastly greater scale and discipline breadth.
• AFRY: European engineering and design consultancy with active hydrogen and renewable energy practices covering feasibility, permitting and owner's engineering. Competes with Justy for industrial and territorial mandates but offers a much broader service portfolio.
• Wood (Wood Group): Global engineering consultancy with significant hydrogen, energy transition and industrial decarbonization capabilities. Competes for complex hydrogen project AMO and engineering mandates that Justy also targets.

Emerging players

• McPhy Energy: France-based hydrogen equipment and integrated solutions provider (electrolyzers, refueling stations). Adjacent rather than direct: Justy consults on ecosystems in which McPhy supplies technology, making them occasional ecosystem partners and indirect competitors for the same hydrogen project budgets.
• Hynamics (EDF subsidiary): French hydrogen subsidiary of EDF offering hydrogen project development, engineering and operations across industrial and mobility use cases. Competes with Justy in the French hydrogen ecosystem engineering space, with stronger parent-company backing.

Direct peers

• PowiDian: French hydrogen systems engineering firm providing turnkey power-to-gas and hydrogen solutions, including feasibility, engineering and integration services. Direct competitor in the French hydrogen ecosystem engineering space.
• Element Energy: UK-based clean energy consultancy with a strong hydrogen practice covering feasibility, techno-economic studies and policy advisory for public and private sector clients. Highly comparable services and customer mix to Justy.
• Hinicio: Brussels-based clean energy and hydrogen strategy/engineering consultancy supporting industrial and mobility clients on H2 feasibility, business models and project development across Europe. Closely matches Justy's hydrogen AMO and feasibility positioning at a similar scale.
