Field expertise serving industry
Commercial subsidiary of Energy Observer, EODev develops reliable, sustainable, and accessible energy storage solutions for the widest possible audience, thanks to its unique expertise on land and at sea and its ready-to-use zero-emission solutions.
EODev designs and manufactures a range of complementary zero-emission solutions for land and sea: the GEH2 (mobile electro-hydrogen unit), the BESSTIE 120 (battery energy storage system), and the REXH2 (zero-emission marine generator for navigation).
All share common values: reliability, performance, ease of use, and clean energy.
Our zero-emission energy production and storage solutions
The zero-emission hydrogen generator
GEH2
Quiet, mobile, and easy to deploy, the GEH2 is a carbon-free energy solution capable of adapting to a wide range of applications and providing electricity wherever it is needed: construction sites and remote locations, events and entertainment venues, data centers, and backup or emergency power. This solution is ideal for reducing your emissions without compromising on reliability or efficiency.
The zero-emission marine generator
REXH2
The marinized and modular “Plug & Play” power generator system designed for marine and river navigation. Silent, clean and certified TAC, this hydrogen fuel cell solution delivers reliable power for vessel propulsion and/or on-board systems. Fully hybrid-compatible, it seamlessly integrates into existing or new electrical architecture, adapting to a wide range of vessel types and operational needs.
The zero-emission battery energy storage
BESSTIE
Sustainable and reliable, BESSTIE is the ideal partner for rapid energy response, whether in stand-alone or hybrid mode. Powered by advanced in-house designed LFP (Lithium Iron Phosphate) technology, it offers exceptional performance and safety. This BESS supplies clean, stable and tailored power for construction sites, grid support, film productions or EV charging stations.
Clean, high-performance alternative to diesel generators
With a new industrial site inaugurated in 2025 and a commercial presence in nearly thirty countries, EODev is transforming Energy Observer's vision into an industrial reality.
From construction sites to outdoor festivals, data centers to marinas, our solutions replace diesel generators with clean, high-performance, and easily deployed alternatives.
