Our promise to the sea.
BZero is Baglietto’s project to implement a green hydrogen production module on its yachts. Using filtered and deionized seawater, BZERO is capable of producing grade 5.0 hydrogen at a maximum pressure of 35 bar. This is achieved through a system of AEM electrolyzers (for a total power of approximately 55 kW), powered primarily by energy from renewable sources.
“One day, water will be the coal of the future: the hydrogen and oxygen that compose it, once separated, will provide an inexhaustible source of heat and light.”

Inside BZERO
From a technical standpoint, the hydrogen produced is stored in solid form, at low pressure and ambient temperature, inside metal hydride cylinders (MH storage). The hydrogen storage and release process is managed by a thermal management system that heats the metal hydrides during discharge and cools them during recharging. The required thermal energy is recovered from the heat generated by a PEM-type Fuel Cell module, approximately 185 kW, which uses hydrogen as fuel to produce electrical power with zero emissions and zero noise. The generated power is regulated through a DC/DC converter onto a central 700 V DC bus, a solution already tested on Baglietto yachts equipped with hybrid technology. Connected in parallel to the Fuel Cell on the same bus is a set of lithium-ion batteries designed to absorb peaks and sudden variations in energy demand on the user side.
PURE ENERGY. CREATED ON BOARD
The prototype is used to develop onboard operating procedures, optimize technical aspects, and obtain the necessary maritime certifications required to operate the system and independently refuel the hydrogen tanks, either autonomously or from external sources. This approach addresses the current lack of infrastructure on one hand, while speeding up refueling times on the other. Particular attention is given to safety and control aspects, which will be ensured by the Classification Society RINA, overseeing and validating each phase of the implementation process through to the final system certification.
