SINGLE

SINGLE will enable ammonia as an energy carrier in the hydrogen value chain through demonstration of a proton ceramic electrochemical reactor (PCER) that integrates the ammonia dehydrogenation (ADH) reaction, hydrogen separation, heat management and compression in a single stage. The realisation of 4 process steps in a single reactor allows the technology to achieve unprecedented energy efficiencies with a project target to demonstrate > 90% (HHV) at system level. The PCER-ADH technology enables to directly deliver purified, pressurised H2 (20 bar). SINGLE will demonstrate the technology at a 10 kg H2 /day scale that will provide a pathway for future scale-up systems ranging from small (fuelling stations) to large centralised (at harbour) deployments. A key technology component is the electrochemical cell, that will be engineered to act as a durable PGM-free ADH catalyst at 500 °C and a voltage-driven membrane separator. The achievements in SINGLE will be an important proof of technological feasibility advancing the technology from TRL3 to TRL5. To strengthen the implementation of NH3 as a H2 carrier, SINGLE will actively disseminate and communicate the results to influence stakeholders in the value chain, including standardisation entities within the hydrogen sector. The consortium counts on partners from the industry, institute and academia sector with high world-wide excellence in the respective fields of catalysis, electrochemical membrane reactors, life-cycle assessment, process engineering, control systems and hydrogen fuelling stations.

Standardisation objectives

The overall objective is to identify/establish the regulatory framework for the deployment of the results from the project.

Specific objectives include:

• Identify relevant standards related to ammonia, hydrogen and high temperature pressurised electrochemical reactors
• Collect and provide information on relevant EU legislative and standard frameworks
• Increase and valorise project results by contributing to both creation and revision of standards

Reason for applying to HSbooster.eu services

General:

The technology to be evaluated in SINGLE is novel and few or no direct standards exist. It is therefore of interest to understand the pathway to develop new standards. Understanding the procedure and effort for this is of interest.

Furthermore, they believe that the HSBooster can assist the standardisation activities in the project in the following 2 areas:

1. Utilisation of ammonia as a hydrogen carrier for hydrogen fuelling stations

Knowledge on existing regulations and standards related to transport, storage and handling of NH3 in a hydrogen fuelling station deployment. This relates to safety regulations/standards in terms of quantities and conditions for storage.  

Standards on fuel cell quality of hydrogen. Impurity levels with respect to NH3, H2 and H2O. ISO standard exists, however are there any upcoming changes/modifications. Can they influence the current standard.

2. High temperature (300-700 °C) handling of pressurised NH3 (up to 30 bar) and H2 (up to 30 bar)

Knowledge on standards/regulations/directives related to high temperature pressurised operation with NH3 and H2. Specific standards/requirements with respect to manufacturing, e.g. welding.
