The Eni-MSC cruises trial confirms that Enilive’s 100% HVO diesel biofuel can slash maritime emissions by up to 90% without requiring any expensive ship retrofits. This successful “plug-and-play” roadmap offers the industry a pragmatic, immediate solution to meet strict new EU environmental regulations while staying on course for 2050.
San Donato Milanese | May 12, 2026 – In a landmark development for maritime decarbonization, Energy giant Eni and MSC Cruises have successfully completed a comprehensive trial of 100% Hydrogenated Vegetable Oil (HVO) diesel. The tests, conducted over 2,000 operational hours on the MSC Opera, have confirmed that high-performance cruise engines can achieve drastic emission reductions today, without a single cent spent on mechanical upgrades.
The results provide a powerful “plug-and-play” roadmap for an industry facing the looming financial pressures of the FuelEU Maritime regulation and the EU Emissions Trading System (EU ETS).
The trial moved beyond short-term “pilot” samples. One of the primary engines of the MSC Opera was powered exclusively by pure HVO for roughly 2,000 hours. The data, monitored with the technical support of engine manufacturer Wärtsilä and independently validated by Bureau Veritas, confirmed a seamless transition from traditional fossil fuels.
Key Technical Outcomes:
The success of the Eni-MSC cruises trial arrives at a critical moment. As shipowners scramble to meet the carbon intensity targets set by FuelEU Maritime, HVO emerges as a strategic survival tool. Because it is produced from waste feedstocks, such as used cooking oils and animal fats, HVO allows operators to slash their emission-related costs while maintaining operational flexibility.
Stefano Ballista, CEO of Enilive, commented, “The trial with MSC has demonstrated how HVO diesel biofuel can contribute immediately to the decarbonization of maritime transport. It allows a reduction in climate-altering emissions, calculated along the entire supply chain, of between 65% and 90%. HVO is already available at the ports of Genoa, Ravenna, and Venice for direct delivery via barge, representing a viable solution to comply with FuelEU Maritime obligations.”
Enilive’s HVO is not a futuristic concept; it is a current industrial reality. The fuel is produced at Enilive’s flagship biorefineries in Venice and Gela, utilizing residues from the agri-food industry.
For MSC Cruises, the trial is a pillar of their broader “Multi-Fuel” strategy. By proving that HVO can work alongside existing LNG and Bio-LNG solutions, the cruise line is closing the gap toward its Net Zero 2050 goal.
Michele Francioni, Chief Energy Transition Officer of MSC Cruises, commented, “We are very pleased to have confirmed the technical feasibility of 100% HVO on our cruise ship. HVO constitutes an immediate opportunity that could be deployed on board to accelerate the transition towards renewable fuels, bringing us a step closer to our ultimate goal of reaching net zero GHG emissions by 2050.”
The maritime industry has often been criticized for being “slow to change,” but the Eni-MSC cruises partnership proves that when the technology (HVO) matches the infrastructure (Wärtsilä engines), the results are instantaneous.
As bunkering hubs in the Mediterranean continue to scale their HVO availability, the MSC Opera trial will likely be remembered as the moment “Drop-in” fuels became the industry’s most pragmatic weapon against carbon.
Eni is an Italy-based global integrated energy company committed to a low-carbon future. The company’s strategy centers on achieving carbon neutrality by 2050 through resource optimization, expanded renewable capacity, and circular economy initiatives. Eni focuses heavily on the production of biofuels from waste and agricultural residues, leveraging its global footprint to facilitate the energy transition across multiple sectors.
Enilive, a wholly owned Eni subsidiary, is a leading producer and distributor of low-carbon energy carriers for transport. As Europe’s second-largest HVO producer, Enilive operates over 5,000 service stations and provides a suite of ready-to-use fuels, including hydrogen, bio-LPG, and biomethane. Its maritime expansion is a core component of its mission to provide immediate, scalable decarbonization solutions.
