    Building the world’s best marine battery takes work… and destruction testing. We select chemistry that avoids fires even in extreme conditions — like shooting it with 12 nails to see if we can trigger a thermal runaway. With this design, we think we’ve nailed it. 😉 The Leviathan™ energy storage system is engineered so that gas is safely extracted away from the vessel, and the ship continues drawing power from unaffected parts of the system. We won’t put something on board that we wouldn’t sail on ourselves.

    Last week at SF Climate Week, Obvious Ventures and Propeller hosted a panel featuring our CEO Steven H. alongside Vatn and Navier. The discussion focused on autonomy at sea and the electrical systems empowering it. An autonomous vessel is only as capable as the power system underneath it. Autonomy gets the headlines, but the compute, controls, and redundancy it depends on require a fundamentally different power architecture, one that diesel struggles to deliver. Thanks to Obvious Ventures and Propeller Ventures for hosting, and to the Vatn and Navier teams for the conversation.

  • We were honored to speak at the UM Naval Architecture & Marine Engineering program. The next generation of naval architects is asking the right questions, with electric ships taking center stage. The future of maritime innovation is being built in classrooms like these.

    Students, staff and alumni of UM Naval Architecture & Marine Engineering gathered at Pierpont Commons for the department's first Sustainability Symposium—an afternoon of industry talks, student presentations, and insights into the future of sustainable maritime engineering. The symposium was funded by a donation from Drew Orvieto (BS NAME '10), who has helped install electric systems on hybrid-electric ferries for Siemens Energy, including Wenatchee, Washington State's first ferry converted to hybrid-electric propulsion. He wanted to donate to the department to help share his passion for sustainability and inspire people the way his grandfather had inspired him to pursue engineering. "He was a completely self-made civil engineer; [he] started his own business, traveled all around the world developing soil testing technology for roads, primarily in developing nations," said Orvieto. "He was such an inspiration to me that I thought it would be cool to give back to a department that gave me so many opportunities." Orvieto presented on the tips and challenges to building and launching electric and hybrid ferries. Alum Eileen Tausch (BSE NAME ’13, MSE NAME ’14) also presented her work to develop marine batteries with Fleetzero, a mariner-owned start up in Houston. She is helping to launch a hybrid-electric support vessel for a Singapore-based company. The vessel is designed to deploy cushions for ships exchanging cargo. After the industry talks, two graduate students presented their thesis research and two groups of undergraduates presented their capstone design projects. For their capstone projects, students designed a ship for an application of their choice. Their designs were comprehensive—covering the engines, electronics, hull shapes, propellers, crew areas, and any other components required for the ship to do its job. During the symposium, students presented calculations proving that their ships were seaworthy and met current regulations. They also defended every design choice, down to the types of steel selected to construct the ship. The students were competing for a cash prize to the best graduate and undergraduate presentation. Owen Baldwin—who discussed decarbonization strategies for vessels in Michigan—won the award for best graduate presentation. The award for best undergraduate project was taken by the team that designed a vessel to clean up plastic pollution from rivers in the Philippines.

  • 90% of global trade moves by ship. Yet maritime is one of the last industries to modernize. Fleetzero has set out to chart the course for the future of shipping. Fleetzero's Steven H. will be on the panel at Autonomy at Sea, a part of SF Climate Week 2026, hosted by Obvious Ventures in San Francisco on April 23. We'll be talking about what it actually takes to electrify long-haul cargo shipping: the modular battery systems, and why now is the moment. Join us if you're in SF. 👇 www.luma.com/AutonomyatSea

  • We’re excited to announce Fleetzero’s $43M Series A led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy, 8090 Industries, Y Combinator and more. This funding accelerates production of our Leviathan™ hybrid and electric propulsion system and supports the opening of our new manufacturing and R&D headquarters in Houston, TX. We believe electrification and autonomy will define the next era of shipping by making it more affordable, safer, cleaner, and scalable. The future of marine technology is being built now! ⚡️

    We love working with great partners! 🤝 Fleetzero and American Bureau of Shipping (ABS) have signed a memorandum of understanding (MoU) to advance containerized marine battery systems, another step toward making zero emission power both safe and scalable at sea. This work brings together Fleetzero’s battery expertise with ABS’s leadership in safety and classification. The result is faster progress toward future standards and broader commercial deployment. ⚡ We’re proud to be working with ABS to set the bar for what marine electrification can be. The future of shipping is electric, and it’s being built now.

    Fleetzero is leading the charge to electrify cargo vessels by driving down the cost of electrification. Great post, Andrew Beebe. We are at an inflection point in the shipping industry where electric vessels are becoming dramatically cheaper for operators than traditional diesel propulsion! #electrification #Fleetzero

    A decade ago we went long on electrification, convinced it would reshape industries far beyond cars. The market has since delivered a master class in momentum. What started as a climate thesis has exploded into one of the most powerful economic rewires underway — infrastructure, logistics, manufacturing, all getting pulled into the current. And the pace isn’t slowing; if anything, it’s accelerating. What’s been especially fun is watching the world keep handing us evidence like it’s trying to win bonus points. EVs are the warm-up act. The next wave is bigger, faster, and still building up charge.
