Biogas Fuels
CNG & LNG Refuelling
As the UK transport sector accelerates its shift towards cleaner, low-carbon operations, biogas fuel is fast becoming the first-choice solution for fleets looking to cut emissions without compromising performance. With both CNG and LNG refuelling now increasingly available nationwide, understanding how each option supports operational efficiency is essential for fleet managers planning a future-proof sustainability strategy.

The Basics of Biogas
Biogas is produced by breaking down organic waste from food waste to agricultural residues through anaerobic digestion. When upgraded to biomethane, it becomes a highly efficient, low-carbon replacement for traditional diesel, perfectly suited to heavy goods vehicles.
Why biogas matters
- Up to 84% CO₂ savings
- Compatible with leading gas truck models from Scania, Volvo and Iveco
- Ready-to-deploy today — no waiting for future technology
- Supports circular, localised UK energy systems
Roadgas is committed to supporting the UK’s transition to renewable fuels. Learn more about our approach to clean fuel solutions on our About Us page.
Understanding CNG
CNG is biomethane compressed to high pressure and stored in onboard gas cylinders. It’s widely used for regional, urban and mixed-route logistics because of its excellent cost efficiency and strong emissions performance.
CNG offers
- Lower cost per mile
- High emissions reduction
- Quick, safe and reliable fuelling
- Ideal suitability for short- to medium-range operations

Advantages and Limitations of CNG Refuelling
Advantages
- Excellent cost savings vs diesel
- Simple station infrastructure
- Ease of refuelling
- Strong nationwide availability
Limitations
- Shorter vehicle range than LNG
- Slightly longer fuelling time
- Best suited to regional operations
Understanding LNG
LNG is biomethane chilled to -160°C, turning it into a liquid and significantly increasing its energy density. It’s the preferred choice for long-distance trunking routes and heavy payloads.
LNG offers
- The longest driving range of any renewable gas
- High efficiency for long-haul operations
- Ultra-fast refuelling
- Reliable, stable performance
Roadgas also develops bespoke on-site depot LNG systems, helping fleets tailor infrastructure to specific operational demands. Explore our custom engineering solutions on our Bespoke Stations page.
Advantages and Limitations of LNG Refuelling
Advantages
- Longest range capability
- Very fast refuelling
- Perfect for trunking and distribution
- Strong CO₂ reduction potential
Limitations
- Higher vehicle and tank cost
- More specialised infrastructure
- Best for long-haul routes
CNG & LNG – Key Differences for Fleet Operators
Both fuels are part of the UK’s low-carbon transport future — but they serve different needs.
Feature | CNG | LNG |
Fuel State | Compressed gas | Cryogenic liquid |
Best Use Case | Urban/regional deliveries | Long-distance trunking |
Refuelling Time | Fast | Faster |
Range | Moderate | Very high |
TCO (Total Cost of Ownership) | Lower | Competitive |
Infrastructure | Simple | Simple |
