Hydro Ecotech

A project led by Hydro Ecotech to develop and commercialize the HydrogenFusion onboard CO₂-to-hydrogen system for auxiliary and main marine engines, with early demonstrations and promotion centered around Marseille and the Euromaritime 2026 trade fair.

Hydro Ecotech markets its core hydrogen injection concept as "HDT" hydrogen, a form of hydrogen produced onboard and injected into the intake or combustion chamber of internal combustion engines to enhance combustion efficiency, reduce fuel consumption, and cut emissions.[3] The approach aligns with broader research on diesel–hydrogen dual‑fuel engines, where small hydrogen additions can improve flame propagation and reduce certain pollutants, though overall benefits depend strongly on engine calibration and operating conditions.[3]

CarboNow is a digital platform integrated into Hydro Ecotech’s solution stack that aims to generate automated carbon performance reports, track emission reductions in real time, and support the monetization of avoided emissions through carbon credits. The platform is presented as using artificial intelligence and blockchain to provide traceable, tamper‑resistant records of fuel savings and emission reductions for industrial operators and shipowners.

HydrogenFusion is presented by Hydro Ecotech as a maritime technology that captures carbon dioxide from engine exhaust gases, reacts it with water and a chemical mixture, and produces high-purity hydrogen in a closed loop for immediate onboard use.[2] The system is targeted at marine engines, particularly auxiliary engines on ships, and is designed to generate hydrogen on demand while operating without external energy sources such as solar or nuclear, according to company statements.[2]
