The transition to sustainable energy in the maritime sector demands more than ambition, it requires precision. That is why Alicat Scientific is proud to support the TU Delft Hydro Motion Team as a Bronze Partner in their groundbreaking 2025 project. They aim to design, build, test, and race Mira<\/em>, a hydrogen\u2011powered foiling boat designed with a dual hydrogen system, one gaseous hydrogen tank and one fully integrated liquid hydrogen tank, competing at the Monaco Energy Boat Challenge.<\/p>\n

Equipping this innovative fuel system with our MCRQ mass flow controllers<\/a> enables the team to manage hydrogen fuel delivery safely and accurately, helping them prove that liquid hydrogen can power the next generation of clean marine propulsion.<\/p>\n

[\/et_pb_text][et_pb_heading title=”The Challenge: Making Hydrogen Work for Maritime Transport” _builder_version=”4.27.4″ _module_preset=”default” title_level=”h3″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_heading][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” custom_margin=”||2rem||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n

The goal of the TU Delft Hydro Motion Team<\/a> is as ambitious as it is inspiring. They plan to design, build, test, and race a fully functioning boat equipped with a dual hydrogen system, all within one year, and to compete at the Monaco Energy Boat Challenge 2025.<\/p>\n

But beyond the competition itself, the team\u2019s mission reaches further. By proving that a boat can operate successfully on liquid hydrogen, they aim to spark broader innovation across the maritime sector. This work demonstrates hydrogen\u2019s potential as a clean, scalable alternative to fossil fuels.<\/p>\n

This project builds on the team\u2019s past successes with compressed hydrogen, already a proven, zero\u2011emission marine fuel. Now, as the team pushes for more range and onboard efficiency, storage volume and energy density are the next big challenges.<\/p>\n

To solve this, the team chose to work with liquid hydrogen. Its volumetric energy density is three times higher than compressed hydrogen at 350 bar. That makes it a powerful way to save space and extend endurance, key requirements in performance vessels.<\/p>\n

But storing and using liquid hydrogen introduces challenges. The fuel must be kept at \u2212253\u00b0C, requiring insulated cryogenic tanks. The team addresses this with a custom double\u2011walled, vacuum\u2011insulated carbon\u2011fiber tank system. This limits heat ingress to just 7 watts, equivalent to a small LED bulb. To avoid wasting energy, waste heat from the fuel cell is used to bring hydrogen up to the required ~20\u00b0C operating temperature before reaching the fuel cell.<\/p>\n

The trade\u2011offs (boil\u2011off rates, tank volume, storage weight, and onboard vaporization) are exactly the kinds of real\u2011world constraints this project is designed to explore. And while Mira<\/em> is a compact foiling boat, the bigger question remains: could a system like this scale to larger vessels, such as ferries? That is the kind of thinking Alicat is excited to support with partners who are pushing the boundaries of what is possible.<\/p>\n

Before reaching the fuel cell<\/a>, it passes through a vaporizer, transitioning into gas at ambient temperature. This phase is critical: delivering gas at the right pressure and flow requires stable regulation, fast feedback, and precise control.[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” module_alignment=”center” custom_margin=”||0px||false|false” custom_padding=”||2rem||false|false” custom_padding_last_edited=”off|desktop” custom_css_free_form=”selector figure {|| display: table;|| margin-left: auto;|| margin-right: auto;|| text-align: center;||}||||selector figcaption {|| caption-side: bottom;|| display: table-caption;||}||||selector img {|| margin-bottom: 1rem;||}” locked=”off” global_colors_info=”{}” custom_css_main_element_last_edited=”on|phone” theme_builder_area=”post_content”]<\/p>\n

To meet this need, the team integrated the Alicat MCRQ mass flow controller<\/a> immediately downstream of the vaporizer. This device manages the mass flow of hydrogen gas into the fuel cell and enables:<\/p>\n
