Description du projet
De l’hydrogène pour les trains et les camions
Grâce au financement de l’entreprise commune «Piles à combustible et Hydrogène 2» (FCH 2 JU), le projet PRHYDE vise à élaborer des recommandations pour un protocole non propriétaire de ravitaillement en carburant des véhicules lourds utilisé pour les futures activités de normalisation des camions et autres systèmes de transport lourd appliquant les technologies de l’hydrogène. Sur la base des protocoles de ravitaillement existants et de l’état actuel de la technique pour le ravitaillement en hydrogène comprimé (gazeux), différents protocoles de ravitaillement en hydrogène doivent être développés pour les grands systèmes de réservoirs avec des pressions de service nominales de 35, 50 et 70 MPa en utilisant des simulations ainsi qu’une vérification expérimentale. La perspective de l’industrie est largement capturée à travers un processus de participation intense des parties prenantes à toutes les étapes du projet. Les travaux permettront le déploiement généralisé de l’hydrogène pour les applications destinées aux véhicules lourds dans les transports routiers, ferroviaires et maritimes. Les résultats constitueront un guide précieux pour la conception de la station, mais également la condition préalable au déploiement d’une infrastructure hydrogène standardisée et rentable.
Objectif
The objective of the proposal is to build the foundations of non-proprietary heavy duty refueling protocols for large tank systems (larger than 10kg), such as the ones found in heavy duty hydrogen applications. The consortium of PrHyde involves all the types of stakeholders linked with hydrogen HD refuelling. It and is therefore well suited to take end user needs, learnings from existing light duty protocols, learnings from the field, requirements for heavy duty applications, existing prior work (e.g. HyTransfer), considerations for improvements and requirements for safety into account and combine those into a proposal for a protocol that meets long term customer needs. Key metrics are refueling time, potential for cost reduction and ease of use. Although the consortium is formed by a large variety of companies, further partners are involved through a series of workshops to make sure the wider industry perspective is captured. The protocol to be developed is validated by simulation and experimental work on single tanks and multi-tank systems, showing that the proposed protocol works as intended and the understanding of thermodynamic effects on large, multi-vessel systems is adequate. Performance specifications for components and application-to-infrastructure communications are a planned by-product of the project. The results of the project will be used to develop an international standard for wide reach and adaptation outside of the project scope. The work will enable the widespread deployment of hydrogen for heavy duty applications, such as trucks, trains, etc. but also transport systems. The results are both a valuable guidance for station design, but also the prerequisite for the deployment of a standardized, cost effective infrastructure. To maximize impact, solutions are developed for pressure levels of 35MPa, 50MPa and 70MPa and non-gaseous storage options are analyzed and benchmarked against current state of the art storage and refueling performance.
