Project description
Hydrogen for trains and trucks
With funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (FCH 2 JU), the PRHYDE project is aiming to develop recommendations for a non-proprietary heavy-duty refuelling protocol used for future standardization activities for trucks and other heavy-duty transport systems applying hydrogen technologies. Based on existing fuelling protocols and current state of the art for compressed (gaseous) hydrogen fuelling, different hydrogen fuelling protocols are to be developed for large tank systems with 35, 50, and 70 MPa nominal working pressures using simulations as well as experimental verification. A broad industry perspective is captured via an intense stakeholder participation process throughout the project. The work will enable the widespread deployment of hydrogen for heavy-duty applications in road, train, and maritime transport. The results will be a valuable guidance for station design but also the prerequisite for the deployment of a standardized, cost effective hydrogen infrastructure.
Objective
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.
