The Petroleum and Natural Gas Regulatory Board (PNGRB) has unveiled its 2030 roadmap for small-scale LNG (SSLNG), highlighting an apparent economic advantage of LNG over diesel. PNGRB’s analysis places delivered LNG costs at approximately Rs 1,571 per MMBTU, compared to diesel at Rs 2,583 per MMBTU—making LNG about 40% cheaper on an energy-equivalent basis.

For trucking fleets, this translates into 20–30% lower fuel costs per kilometer, as LNG-powered heavy-duty vehicles achieve 3.5–4.2 km per kg versus 2.7–3.3 km per litre for diesel. On paper, the economics look transformative.

However, India’s on-road reality is far removed. The country currently has only about 700 LNG trucks in operation and just 20 retail LNG outlets nationwide. PNGRB’s target—50,000 LNG trucks and nearly 190 outlets by 2030—would require a 70-fold expansion in fleet size and a 10-fold increase in station count within just six years.

Infrastructure bottlenecks compound the challenge. India’s LNG terminals have 18 loading bays, with eight more under construction. PNGRB projects that 27–28 bays will be needed by 2030, operating in two shifts, just to meet forecast demand. Even then, the margin for growth would remain slim.

Capital costs are another hurdle. An LNG truck costs around Rs 65 lakh, compared to Rs 45 lakh for a diesel truck. With a payback period estimated at 11–12 years—longer than the typical 10-year operational life of a diesel truck—the economics deter fleet operators.

The price advantage itself is fragile. Retail LNG sells at Rs 82–87/kg against diesel at ~Rs 108/kg, but this relies on stable global LNG markets. Volatility in spot cargoes could erode the parity, unlike China where domestic LNG and byproduct gas kept prices consistently lower.

PNGRB also projects demand from industries and city gas distribution (CGD) networks via LCNG stations. But CGD players acknowledge LNG as a temporary measure until pipelines arrive, meaning demand may peak and fade. Industrial uptake is expected to remain limited to catchment areas around LNG terminals.

The Big Picture: On paper, LNG promises cleaner emissions (20–30% lower CO₂, with sharp reductions in NOx and particulates) and lower costs. In practice, however, the lack of retail corridors, high truck capex, infrastructure gaps, and policy uncertainty mean India’s LNG trucking sector risks stalling before takeoff.
