Making Hydrogen Retrofits Ship-Ready: AURELIA’s Hands-On Work

Our recent collaboration with Newlight, lomarlabs, and Lomar on hydrogen retrofits for two- and four-stroke engines reflects AURELIA’s belief in turning ideas into real solutions.

Newlight has successfully completed Factory Acceptance Testing (FAT) with RINA for its hydrogen retrofit system.

The tests validated safety layers, control and monitoring logic, electrical integration, and engine behavior under real-world duty profiles. From shore-based testing on a four-stroke genset to sea trials on a two-stroke main engine, the system demonstrated stable performance, smooth changeover between hydrogen and conventional fuel, and measurable efficiency gains.

AURELIA’s contribution was central to translating this innovation into a ship-ready solution. We led the engineering design integration: defining interfaces, optimizing layouts, routing systems, and preparing detailed commissioning plans.

Every decision was guided by a single question: “How can this system be installed safely, efficiently, and repeatedly on existing vessels?” By ensuring alignment with RINA Class Rules and the IGF Code, we made it possible for the retrofit package to move seamlessly from the factory floor to a commercial ship.

Our role wasn’t just technical, we coordinated closely with partners to turn individual expertise into a single, functioning system. The result is a retrofit that is robust, compliant, and ready for Harbor Acceptance Testing (HAT) under RINA supervision, and eventually, commercial vessel installation.

For us at AURELIA, the milestone goes beyond awards or recognition. It’s proof that decarbonization solutions can be engineered, integrated, and applied at scale, without disrupting existing fleets. This is how we bring hydrogen innovation into practice.
