Hydrogen burns in the same engine.

You don't replace the car. We feed green hydrogen into a petrol or diesel engine, so it burns less fossil fuel.

  • Two prototypes
  • Petrol + H₂
  • Diesel + H₂

What is H2brid

H for hydrogen.
H for hybrid.

H2brid is a hydrogen-as-second-fuel system for vehicles with internal combustion engines. The engine stays the same. Part of the conventional fuel burned in it is replaced with green hydrogen, which cuts emissions.

The hydrogen is produced by SG dujos, one of the first companies in Lithuania developing hydrogen technologies for transport. Alongside electric vehicles and biomethane, it is another path to a cleaner transport sector.

Where the system fits

Passenger cars

Buses

Trucks

The first swallows

Two prototype cars

Officially registered as prototypes, developed together with VILNIUS TECH scientists and fueled with green hydrogen produced by SG dujos.

Prototype A

Petrol hatchback

A car with a spark-ignition engine converted into a petrol–hydrogen hybrid: part of the petrol in the combustion process is replaced with green hydrogen.

Fuel
Petrol + H₂
Engine
No major structural changes
Status
Officially registered prototype
Prototype B

Diesel hatchback

A car with a compression-ignition engine converted into a diesel–hydrogen hybrid: part of the diesel in the combustion process is replaced with green hydrogen.

Fuel
Diesel + H₂
Engine
No major structural changes
Status
Officially registered prototype
Why it matters

Another path to cleaner transport

Works with existing engines

No need to replace the whole fleet. The hydrogen system is fitted to conventional internal combustion engines, from passenger cars to trucks.

Green fuel

The hydrogen is green, produced in Lithuania from renewable energy rather than imported as fossil fuel.

Only infrastructure is missing

The technology is already on Lithuanian roads. The next step is expanding the hydrogen refueling network.

The project

"Use of Green Hydrogen in the Transport Sector"

The project was implemented by UAB "SG dujos Auto" under the state program "Implementation of Mission-Based Science and Innovation Programs".

  • Project No. 02-002-P-0001
  • Goal — to develop and test green hydrogen supply and utilization systems in internal combustion engines
  • Two cars officially registered as prototypes
  • Project partner — VILNIUS TECH
