LNG for Heavy Vehicles

LNG delivers higher energy output with lower fuel usage

LNG is a cleaner, high-energy fuel that can extend vehicle life and significantly reduce emissions. It is a practical and economical choice for long-haul buses, trucks and tippers on Indian highways.

Fuel cost
~50% lower vs diesel*
Indicative for high-mileage fleets on fixed corridors.
Emissions
Up to 20% CO₂ reduction
With almost zero SOx and deep NOx cuts.
Asset life
+5–7 years extended
By converting older buses and heavy vehicles to LNG.
  • Higher drive range on the same tank – ideal for STU routes and logistics corridors.
  • Cleaner combustion can reduce engine deposits and improve long-term reliability.
  • Domestic natural gas supply supports stable fuel economics over time.
LNG-powered heavy vehicle concept
LNG-ready concept for state transport undertakings

*Illustrative economics – actual values depend on route, duty cycle and local prices.

Use cases

Designed for high-mileage, high-duty fleets.

LNG is especially suited for vehicles that run long distances daily on fixed corridors. Typical applications include state transport buses, line-haul trucks, mining tippers and dedicated freight fleets.

Intercity & express buses
Long-haul trucks & trailers
Mining & construction tippers
Milk / bulk carriers
🚌
State transport buses
Strong savings on predictable routes with depot-based refuelling planning.
🚛
Line-haul trucks
Long-distance corridors benefit from fewer stops and cleaner combustion.
⛏️
Mining & tippers
Better local air quality on sites, with lower emissions and robust duty support.
Diesel vs LNG – operating view
Per km cost
LNG ~50% of diesel
Indicative for high-mileage fleets on fixed corridors.
Range
Higher range / tank
Energy-dense storage supports long-haul planning.
Emissions
Up to 20% CO₂ reduction
Near-zero SOx and significant NOx reduction.
After-treatment
Simpler than diesel
Cleaner burn can reduce treatment complexity.
Diesel to LNG opportunity

High diesel states = strong LNG potential.

India’s transport segment offers large conversion headroom. LNG corridors along key highways unlock reliable, repeat demand from buses and heavy trucks.

State Diesel demand (Thousand MT)
Gujarat5,608
Maharashtra9,529
Karnataka6,874
Rajasthan7,829
Punjab2,870
Odisha3,875

Even partial conversion of heavy vehicles over the next few years can create strong base-load LNG demand and accelerate station development.

For MSRTC & STUs

Extend bus life and lower operating burden.

LNG conversion can extend the usable life of buses by 5–7 years, enabling older assets to operate cleaner and more economically on fixed corridors.

  • Target high-mileage routes with predictable demand and depot access.
  • Plan refuelling around day/night operations to reduce downtime.
  • Lower fuel bill and improve fleet reliability over the long term.

Engine & fuel system

How LNG is used in heavy vehicles.

  • 1
    Storage in LNG cylinder
    Vacuum-insulated cylinder stores LNG safely with minimal boil-off.
  • 2
    Vaporisation & pressure control
    Vaporiser + regulator ensures stable gas supply before fuel rail.
  • 3
    ECU-controlled gas supply
    ECU manages injection to optimise power, efficiency and emissions.
  • 4
    Safety & testing
    Cylinders tested for vibration, drop and high-temp performance with safety valves.
