BEP – Much Better Fuel
CS

Cleaner combustion.Less fuel.

BEP is a patent-protected catalyst dosed into the fuel. Fuel burns more completely and engines use less.

Ferrocene, Fe(C₅H₅)₂

One dose in the tank, four gains on the road

The effect starts with catalytic action during combustion and carries all the way to the exhaust and the service bill. Every step links to the measurement behind it.

The catalyst in detail

  1. Cleaner combustion

    BEP carries iron bound in ferrocene into the combustion chamber. There it acts catalytically during combustion: the fuel burns more completely and soot oxidation is enhanced.

  2. Less fuel

    When more of every litre burns, the engine does the same work on less fuel, from passenger cars to quarry machines.

  3. Fewer emissions

    Less fuel burned means less CO₂. A complete burn also leaves less soot and less carbon monoxide in the exhaust.

  4. Less maintenance

    Fewer carbon deposits keep particulate filters (DPF) and exhaust gas recirculation (EGR) valves clean for longer.

One principle for every combustion engine

BEP acts catalytically during combustion, so it suits any diesel or petrol engine design. Each tile shows the strongest result in our ledger.

Dosing in detail

  • Tablet

    1 tablet

    per 40 l of fuel

    Drop it into the tank when you refuel. Ideal for cars, vans and smaller fleets.

  • Granulate

    12.5 g

    per 1,000 l of fuel

    Dissolves into a concentrate that doses whole storage tanks at once.

  • Liquid

    1 l

    per 1,000 l of fuel

    Dosed straight into bulk fuel at the depot or the pump.

Patent-protected in Europe, the US and South Africa

BEP technology is protected by granted patents in the Czech Republic, five European countries (Germany, France, the United Kingdom, Italy and Greece), the United States and South Africa. The South African patent, granted in 2026, protects the newest BEP composition, developed in 2025. Patent proceedings for this composition are under way in 23 more countries: 20 ARIPO member states including Zimbabwe, Kenya and Ghana, the Democratic Republic of the Congo, Angola and Vietnam.

From the first tablet to the newest composition

Three development stages from 2013 to 2018, then patents in Europe, the US and South Africa and independent validation.

Read our journey
  1. Step 12013–2015

    The composition

    First tablets in 2013, then the search for the optimal ferrocene-based composition. Fuel with the tablet met all assessed EN 590 and EN 228 parameters (VÚRUP, 2013).

  2. Step 22015–2017

    Fast dissolution

    Dissolution cut from up to two hours to about three minutes for today’s tablets. Patent application filed (priority 17 July 2017).

  3. Step 32018

    Liquid for tanks

    Liquid form for dosing straight into fuel tanks completed: 1 litre per 1,000 litres of fuel. Czech patent granted.

  4. Step 42021

    European and US patents

    EP 3655508 and US 11,203,727 granted; exclusive licence to Blue Marble Services, recorded in the European Patent Register.

  5. Step 52025

    Newest composition, field validation

    A further developed composition, protected by a new patent family. Independent field validation by NUST in Zimbabwe.

  6. Step 62026

    South African patent

    ZA 2025/06075 granted on 25 March 2026 for the newest composition; proceedings are under way in 23 more countries.
