Everllence Introduces ESAL to Increase Vessel Efficiency by up to 6%

Everllence has unveiled a novel technology called Engine Supported Air Lubrication (ESAL) to enhance vessel efficiency by as much as 6%. The company has also published an industry white paper titled "A leap in vessel energy efficiency advancement with engine-supported air lubrication," which explains the significance of energy efficiency in shipping's path to net zero emissions.

Everllence argues that energy efficiency advancements are the most dependable approach to lowering emissions and costs, especially since the transition to net zero is still unfolding. ESAL, positioned as a practical solution, cuts fuel consumption, diminishes regulatory exposure, and increases vessel efficiency through the integration of hull air-lubrication with the main engine. This integration delivers value today, irrespective of future fuel or regulatory conditions.

Bjarne Foldager, Head of Two-Stroke Business at Everllence, emphasizes that the maritime energy transition should begin with reducing energy demand. He asserts that solutions improving efficiency today will retain their value under any credible future framework, making efficiency improvements a prerequisite rather than an alternative to fuel transition.

Pending final IMO rules, Everllence believes that ESAL already presents a clear business case. By minimizing fuel consumption, ESAL reduces emissions, compliance costs, and exposure to fuel-price and regulatory volatility. Consequently, the fuel savings from ESAL can yield substantial long-term economic and environmental benefits throughout a vessel's operational lifespan.

Per Cato, SVP and Head of Engineering Two-Stroke at Everllence, highlights that reduced fuel consumption directly translates to lower absolute emissions, decreased compliance costs, and decreased exposure to volatility in fuel and regulatory costs. He emphasizes that ESAL is not merely a technology but a strategic response to the uncertainty in the regulatory landscape.

Everllence concludes that energy efficiency is crucial to shipping's decarbonization and positions ESAL as a practical, forward-looking solution. By combining air lubrication with the main engine, ESAL enhances net efficiency gains by up to 6%, further reducing fuel consumption, emissions, regulatory costs, and fuel demand. This technology supports competitiveness and the transition to net-zero shipping.
