What Inocel does

INOCEL is a French deep-tech company that designs and manufactures high-power hydrogen PEM fuel cell systems and modular zero-emission generators. Founded in 2022 (originating from a 2020 collaboration with the CEA), the company is headquartered in Saint-Égrève, France, with a 15,000 m² gigafactory in Belfort, an R&D center in Grenoble, and a system integration center of excellence (INOCEL Advanced Technology, IAT) in Mougins. Its core products are the GEN-Z family of containerized hydrogen generators (300, 600, and 1300 kVA) and the Z-series fuel cell stacks (Z100-G at 100 kW, Z125-G at 125 kW, and Z300-S at 300 kW), built on over 25 years of CEA fuel cell research and protected by approximately 25 patents covering hardware and proprietary energy-management software. The Z300 stack delivers over 300 kW of power, up to 65% electrical efficiency, and a 1.5-second dynamic response from idle to full power — enabling the fuel cell to act as a primary energy source without a large battery buffer.

The company sells to enterprise customers across stationary power (data centers, critical infrastructure, construction sites, events, airports/ports, and industrial backup) and is preparing entry into heavy mobility and maritime through Z100-G/Z125-G systems and the 2027-planned Z100-M marine variant. Its go-to-market combines direct field sales, a 2025 strategic partnership with EQUANS for turnkey deployment, and a managed-service layer that includes installation, commissioning, fuel supply, rental, and maintenance. Revenue streams span hardware sales (generators and fuel cell systems), professional services (engineering integration via IAT, installation, and maintenance), and managed services (rental and fuel supply). Named customers are limited in disclosure, with ACCIONA documented as a port-construction pilot. As of 2024, INOCEL employs around 70 people, and the company has raised approximately €80.5M cumulatively (€16.5M in 2022 and €64M in March 2024) to fund industrialization, ramp production to 90 MW by 2027 and 3 GW by 2032 at Belfort, and expand commercial activities across Europe, including new business development hires in Norway and the Netherlands.
