Renewable Fuels for CHP

Sustainable Fuel Solutions for Low-Carbon Energy Generation

Fleetsolve Logo Icon

Fleetsolve specialises in the integration of renewable fuels for use in Combined Heat and Power (CHP) and generator systems. We help organisations across the UK reduce carbon emissions from on-site energy generation without compromising on performance, reliability, or system uptime.

From NHS estates to industrial campuses and public-sector energy networks, we support the transition to biofuels, end-of-waste materials, and low-carbon fuels — aligned with UK Net Zero targets and wider sustainability goals.

We offer a complete, compliant fuel solution — from system compatibility assessments and design to fuel supply, installation, maintenance, and HMRC/environmental compliance reporting.

Renewable CHP Fuels We Support

We supply and support a full range of certified renewable fuels for CHP and generator systems:

Bio-Liquids

Bioliquids offer a low-carbon, sustainable fuel option produced from waste materials such as tallow, used cooking oils, and pharmaceutical residues. With only minor adaptations, they can be used in most liquid-fuel CHP engines, making them a practical choice for organisations looking to reduce emissions without compromising performance. Bioliquids support strong operational continuity and are available through bulk delivery or, in some cases, on-site processing — offering flexibility alongside environmental benefits.

Biogas

Biogas is a renewable fuel sourced from anaerobic digestion (AD), landfill gas, or wastewater treatment processes — turning organic waste into a valuable energy resource. When integrated into CHP systems, it enables a truly circular, waste-to-energy solution that supports both sustainability and energy independence. To ensure optimal performance, biogas requires proper clean-up and engine tuning. Fleetsolve offers a full turnkey service — from digester to engine — delivering a seamless, end-to-end solution tailored to your site and fuel source.

Biodiesel (FAME & UCOME)

Biodiesel — including FAME and UCOME varieties — is derived from renewable sources such as used cooking oils and animal fats, making it a sustainable alternative to traditional fossil fuels. It’s drop-in compatible with many CHP platforms, requiring little to no engine modification, which makes adoption both simple and cost-effective. By switching to biodiesel, operators can achieve significant reductions in lifecycle CO₂ emissions while maintaining reliable energy performance.

HVO (Hydrotreated Vegetable Oil)

Hydrotreated Vegetable Oil (HVO) is a high-purity synthetic diesel made from renewable feedstocks, offering a cleaner and more sustainable alternative to conventional diesel. Its advanced refining process results in cleaner combustion, lower emissions, and improved cold-weather performance — making it ideal for year-round operation. HVO is approved by multiple CHP engine manufacturers and fully OEM-compliant, providing a seamless transition for operators looking to reduce their environmental impact without compromising reliability.

Hydrogen: The Future of Zero-Carbon CHP

Hydrogen is a key enabler in the future of clean energy. Fleetsolve supports clients preparing for hydrogen blending or full hydrogen-ready CHP systems, ensuring they remain compliant, efficient, and futureproof.

Our hydrogen CHP services include:

  • Full system assessments for H₂ blend or 100% hydrogen compatibility

  • Support with ATEX/DSEAR compliance and emissions recalibration

  • Supply of hydrogen-ready engines and compatible gas trains

  • Integration into existing fuel networks

  • Strategic planning for phased fuel transitions and regulatory readiness

Why Choose Renewable Fuels for CHP?

Choosing renewable fuels for your CHP system is a powerful way to take control of your carbon reduction journey through on-site, low-emission energy generation.

Whether you’re using bioliquids, biogas, biodiesel, or HVO, all fuel types offer reduced and reportable carbon emissions, making them a smart fit for ESG strategies, CHPQA compliance, and emissions trading schemes. Many of these fuels are waste-derived, supporting the circular economy while offering a practical, scalable alternative to fossil fuels — available and deployable today. Aligned with long-term sustainability and Net Zero commitments, these fuels don’t just reduce impact — they futureproof your energy strategy.

And with Fleetsolve, every renewable fuel is safely integrated into your system, performance-optimised through proper storage, filtration, and ongoing monitoring to keep things running smoothly.

System Compatibility & Conversion Support

Our engineers offer comprehensive technical support to transition existing systems to renewable fuels:

  • Fuel system and engine modifications

  • Emissions recalibration and compliance documentation

  • Control system updates and software tuning

  • Ongoing performance reporting and analytics

We also support multi-site users with consolidated fuel switching strategies, blend trials, and centralised fuel management.
