Marine Transport

There is great potential to apply HYDI’s technology to any application utilising a diesel power for propulsion and for on board generators. As global emissions standards increase the demands for shipping operators to reduce GHG emissions, HYDI is responding with a solution.

Sustainable Marine Power: Hydrogen Solutions for the High Seas

The maritime industry is navigating a new era of environmental regulation. With the IMO targeting significant reductions in carbon intensity by 2030, vessel operators need immediate, scalable solutions. HYDI’s Hydrogen Direct Injection (HDI) offers a proven path to decarbonisation for existing diesel-powered fleets.

Environmental Compliance

Drastically reduce Diesel Particulate Matter (DPM) and Greenhouse Gas (GHG) emissions, ensuring your fleet meets strict port and coastal environmental standards.

Operational Efficiency

Achieve measurable fuel savings on main engines and auxiliary generators, even in high-load marine environments.

Engineered for the Harsh Marine Environment

Marine engines face unique stresses—salt air, high humidity, and constant load. HYDI units are built to thrive where others fail:

  • Corrosion Resistant: Housed in fully-welded 316 Marine Grade stainless steel for maximum durability against saltwater exposure.
  • Hydrogen on Demand: Safety is paramount at sea. Our system produces hydrogen only when the engine is running, eliminating the need for high-pressure hydrogen storage tanks on board.
  • AdBlue & Aftertreatment Support: By ensuring a more complete fuel burn, HYDI reduces soot load on Diesel Particulate Filters (DPF) and can lower the consumption of AdBlue/DEF in modern SCR systems.

Versatile Maritime Applications

From commercial fishing to harbor logistics, HYDI technology is applicable across the marine sector:

  • Aquaculture Support Vessels: Reduce the environmental footprint of feeding and maintenance boats.
  • Ferries & Passenger Transport: Improve air quality for passengers and reduce urban waterfront emissions.
  • Tugs & Workboats: Optimise torque and fuel efficiency during high-stress towing operations.
  • Onboard Generators: Clean up the power source for refrigeration and vessel electronics.

The HYDI Unit

The HYDI unit is a sophisticated but simple to use Hydrogen on demand system. It uses distilled water
and low voltage electricity from the electrical system of the vehicle or plant to produce Hydrogen.

The HYDI unit does not store Hydrogen and employs a number of safety features to prevent Hydrogen
being generated if the engine is not running.

There are no chemicals or additives used in the HYDI unit.

Just pure water.

The HYDI unit uses Bluetooth Applications to display the status on the operation of the unit on
an Android phone or tablet in real time.

Benefits

The HYDI Hydrogen on demand system supplies hydrogen gas to the engine
intake to supplement diesel fuel. The controlled addition of hydrogen into
the engine improves combustion efficiency.

This has the effect of reducing fuel consumption and to reducing carbon and
greenhouse gas exhaust emissions.
