Why fuel-based methods can lead to higher compliance cost

  • Generic emission factors

    The gap between assumed and actual emissions is driven by fuel that is estimated but not actually consumed.

  • Incomplete combustion

    Not all carbon becomes CO2, a share becomes CO, HC and methane slip, however fuel-based formulas count it all as CO2.

  • Sludge removal

    Purification systems remove sludge from fuel prior to combustion. This sludge is recorded as consumed in tank monitoring and BDN records, but it is never burned

  • Manual measurement errors

    BDN variances, tank sounding, and manual data entry each introduce small but compounding errors into the fuel consumption baseline that carry through the emission calculation.

  • Perfect combustion assumption

    Fuel-based methods assume complete, efficient combustion at all engine loads. Engines operate at varying loads and their combustion efficiency changes as the load changes.

The Revelle solution: designed to align with evolving maritime regulations

  • EU Monitoring, Reporting and Verification

    Revelle™ delivers actual emission values with the data quality score and traceability required for annual MRV report submission and verifier sign-off.

  • Data Collection System

    Data from Revelle's sensor stream feeds directly into reporting requirements, providing actual data rather than assumptions.

  • FuelEU greenhouse gas intensity

    FuelEU obligations incorporate CH₄ and N₂O alongside CO₂. Revelle directly measures all three, providing the methodology-aligned data needed for defensible FuelEU compliance reporting.

Revelle™ 3.0: how it works

 

EU MRV Method D.

 

Direct, verified, and in real time, Method D (direct emission monitoring) is the only EU MRV methodology that measures what actually exits the exhaust. Revelle's system installed on your vessel delivers continuous emission data.

Three independent sensor streams; emissions, fuel, and engine load, are cross-verified continuously. Discrepancies between streams trigger automatic quality flags.

 

 

Audit-ready data delivered into your systems

 

Revelle™ does not replace your reporting platform. It feeds verified, method-D emission data directly into your existing EU MRV and workflows via API with meeting requirements for regulatory submission and third-party verification.
