Unlocking 250 kW of Direct Mechanical Boost from Marine Waste Heat.
Without Touching the Prime Mover.
In commercial shipping, meeting stringent CII and EEXI targets cannot rely solely on future fuels that lack current bunkering infrastructure. Real-world decarbonization demands recovering the massive thermal energy currently lost through the stack.
Together with Alexander Borodin, we have been engineering an integration architecture that couples a closed supercritical CO_2 (sCO_2) bottoming cycle directly to the Hydro Puls Direct-Drive (HPDD) core for large 15–20 MW two-stroke engines:
Zero Electrical Conversion Losses: Mechanical power delivered straight to the shaftline via hydraulic Power Take-In (PTI).
Zero Prime-Mover Disruption: Operating strictly downstream of the turbocharger with verified aerodynamic backpressure below 25 mbar.
1 Ton Fuel Saved per Day: Eliminating hundreds of tons of bunker fuel and CO_2 annually per vessel.
Active Torsional Damping: Natural fluidic absorption of severe sea-state propeller shocks and cavitation loads.
A detailed breakdown of the thermodynamic validation, Inconel heat exchange boundary, and hydraulic isolation interface will be shared in the coming weeks.
Stay tuned.
