Dallara and Conflux Develop Liquid Hydrogen Thermal Management for Racing

Dallara and Conflux Technology are working on a project focused on the development of a liquid hydrogen-to-coolant heat exchanger for hydrogen internal combustion engine race cars. The project is aligned with the ACO's hydrogen roadmap targeting 2030, aiming to support manufacturers and racing teams in hydrogen-fueled endurance programs.

The study includes evaluating liquid hydrogen storage and delivery systems, developing a digital twin for vehicle-level assessments. A primary engineering challenge involves preventing coolant freezing at cryogenic temperatures, which can hinder performance.

By utilizing Additive Manufacturing, the collaboration aims to optimize thermal performance, reduce weight, and minimize hydrogen embrittlement risks. This partnership is expected to accelerate the adoption of liquid hydrogen ICE technology in motorsport.
