Standard Fuels for CHP and Generators
Reliable, Proven Fuel Options to Power Your CHP System
While many organisations are advancing toward Net Zero, standard fuels remain essential for the day-to-day operation of Combined Heat and Power (CHP) systems and generators.
At Fleetsolve, we support the safe, efficient, and compliant use of natural gas, diesel, LPG, and other conventional fuels — while helping you plan for a future transition to renewable energy when the time is right.
Fuels We Support
Natural Gas
Natural gas remains the most widely used and cost-effective fuel for CHP systems in the UK, offering a dependable and efficient energy source with clean combustion and a continuous, reliable supply. It’s fully supported by all major OEM platforms, including Guascor, MAN, and RMB, making it a practical choice for a wide range of applications. Better still, many natural gas systems can be future-proofed by upgrading to support hydrogen blends — allowing operators to transition toward lower-carbon fuels without the need for full system replacement.
Diesel
Diesel remains a high-energy, readily available fuel that’s well-suited to both prime power and standby CHP applications. It’s commonly used in off-grid locations and as a reliable emergency backup solution, offering dependable performance when continuity is critical. To meet today’s environmental regulations, modern diesel systems require up-to-date emissions controls — but with the right setup, diesel remains a practical and accessible option across the UK.
LPG (Liquefied Petroleum Gas)
LPG is an excellent choice for rural or off-grid CHP installations, offering a cleaner-burning alternative to diesel and even natural gas, with notably lower CO₂ emissions. Its flexible storage and delivery options make it easy to manage on sites without access to mains gas, while its clean combustion helps reduce maintenance needs over time. Ideal for applications that demand reliable performance with lower environmental impact, LPG provides both efficiency and versatility in a compact fuel solution.
