BioHFO: The Inline Revolution Transforming Maritime Decarbonisation

07 May 2026

TecnoVeritas unveils its patented BioHFO technology at NAVALIA, delivering over 50% emissions reduction with a return on investment in less than two years

At NAVALIA, TecnoVeritas is highlighting BioHFO (Bio Hybrid Fuel Optimiser), its patented inline biofuel processing system. Focused on immediate action and operational efficiency, BioHFO presents itself as the most advanced and profitable technological response on the market for maritime fleets.

How BioHFO Works: Cutting-Edge Inline Technology Unlike traditional solutions, BioHFO stands out for its precision engineering. Its main features include:
• Inline Isolation and Blending: The B100 biofuel is stored in a dedicated and fully isolated tank. The major innovation is that it only comes into contact with the mineral fuel 2 to 3 seconds before the injection pumps.
• Dynamic Optimisation: The system adjusts the biofuel incorporation rate in real-time, depending on the engine load, maximising emission reductions at any point during the voyage.
• Automated Compliance: The system continuously records mass flow data according to the ISO 8217 standard, generating audit-ready data for the MRV (Monitoring, Reporting and Verification) system and including the ISCC sustainability certificate.
Overwhelming Advantages Over Market Alternatives BioHFO's superiority becomes evident when compared to the two main alternatives available to shipowners:

1. Compared to Pre-mixed Bunker Blends (e.g., B30)
• Zero Risk of Incompatibility and Losses: The supply of pre-mixed B30 entails losses during the centrifuge separation process and mechanical risks due to fuel incompatibility. Since BioHFO does not require pre-mixing tanks and injection is immediate, this risk is zero.
• Dynamic vs. Fixed Ratio: While B30 burns at a fixed ratio, BioHFO adapts to the engine load.
• Greater Emission Reduction: BioHFO guarantees a greenhouse gas reduction of over 50% (saving around €300,000/year in ETS costs for a 10,000 GT vessel), in contrast to the modest 10% reduction and €90,000 savings offered by a B30 blend.

2. Compared to LNG (Liquefied Natural Gas) Conversion
• Dramatically Lower Costs (CAPEX): Converting a ship to LNG requires a colossal investment of 5 to 15 million euros. The BioHFO system requires only about €500,000.
• No Engine Modifications: Unlike LNG, which requires deep engine alterations and new bunkering infrastructure in a project that can take 2 to 5 years, BioHFO does not require any engine modifications and is installed during a single drydock stop.
• Ultra-fast Return on Investment: The investment in BioHFO has a return of less than 2 years, compared to the 8 to 15 years for an LNG conversion, making it the obvious choice for ships with 8 to 12 years of remaining lifespan.

Reliability Guarantee With Type Approval certification from DNV and Bureau Veritas, the system is already operational on 8 ships (including ferries, container ships, and cruise ships). The technology records zero mechanical incidents and has already avoided more than 70,000 tonnes of CO₂ in the first half of 2025.

We invite all visitors to NAVALIA International Fair to take a closer look at the BioHFO technology and discover how to transform environmental compliance into a competitive commercial advantage in less than two years. Visit us at stand 3C19.
