Education, Training & Lessons Learned

A suitably trained emergency response force is an essential component for safe implementation of any type of fuel infrastructure. Because of the relative newness of hydrogen as a fuel however appropriate emergency response procedures are not yet well understood by responder workforces across the United States and around the world. A significant near-term training effort is needed to ensure that the future hydrogen infrastructure can be developed and operated with acceptable incident risk. Efforts are presently underway at the HAMMER site in Washington State to develop curricula related to hydrogen properties and behavior identification of problems (e.g. incorrect equipment installation) and appropriate response and other relevant information intended for classroom instruction. In addition a number of hands-on training props are planned for realistic simulation of hydrogen incidents in order to convey proper response procedures in high-pressure cryogenic high leakage or other high-risk accident situations. Surveys of emergency responders fire marshals regulatory authorities manufacturers and others are being undertaken to ensure that the capabilities developed and offered at HAMMER will meet the acknowledged need. This paper describes the training curricula and props anticipated at HAMMER and is intended to provide useful information to others planning similar training programs.

The onset and further development of the hydrogen economy are known to be constrained by safety barriers as well as by the level of public acceptance of new applications. Educational and training programmes in hydrogen safety which are currently absent in Europe are considered to be a key instrument in lifting these limitations and to ensure the safe introduction of hydrogen as an energy carrier. Therefore the European Network of Excellence ‘Safety of Hydrogen as an Energy Carrier’ (NoE HySafe) embarked on the establishment of the e-Academy of Hydrogen Safety. This work is led by the University of Ulster and carried out in cooperation with international partners from five other universities (Universidad Politecnica de Madrid Spain; University of Pisa Italy; Warsaw University of Technology Poland; Instituto Superior Technico Portugal; University of Calgary Canada) two research institutions (Forschungszentrum Karlsruhe and Forschungszentrum Juelich Germany) and one enterprise (GexCon Norway). The development of an International Curriculum on Hydrogen Safety Engineering aided by world-class experts from within and outside NoE HySafe is of central importance to the establishment of the e-Academy of Hydrogen Safety. Despite its key role in identifying the knowledge framework of the subject matter and its role in aiding educators with the development of teaching programmes on hydrogen safety no such curriculum appears to have been developed previously. The current structure of the International Curriculum on Hydrogen Safety Engineering and the motivation behind it are described in this paper. Future steps in the development of a system of hydrogen safety education and training in Europe are briefly described.

Safety is an essential element for realizing the “hydrogen economy” – safe operation in all of its aspects from hydrogen production through storage distribution and use; from research development and demonstration to commercialization. As such safety is given paramount importance in all facets of the research development and demonstration of the U.S Department of Energy’s (DOE) Hydrogen Fuel Cells and Infrastructure Technologies (HFCIT) Program Office. The diversity of the DOE project portfolio is self-evident. Projects are performed by large companies small businesses DOE National Laboratories academic institutions and numerous partnerships involving the same. Projects range from research exploring advances in novel hydrogen storage materials to demonstrations of hydrogen refuelling stations and vehicles. Recognizing the nature of its program and the importance of safety planning DOE has undertaken a number of initiatives to encourage and shape safety awareness. The DOE Hydrogen Safety Review Panel was formed to bring a broad cross-section of expertise from the industrial government and academic sectors to help ensure the success of the program as a whole. The Panel provides guidance on safety-related issues and needs reviews individual DOE-supported projects and their safety plans and explores ways to bring learnings to broadly benefit the DOE program. This paper explores the approaches used for providing safety planning guidance to contractors in the context of their own (and varied) policies procedures and practices. The essential elements that should be included in safety plans are described as well as the process for reviewing project safety plans. Discussion of safety planning during the conduct of safety review site visits is also shared. Safety planning-related learnings gathered from project safety reviews and the Panel’s experience in reviewing safety plans are discussed.

A best practice is a technique or methodology that has reliably led to a desired result. A wealth of experience regarding the safe use and handling of hydrogen exists as a result of an extensive history in a wide variety of industrial and aerospace settings. Hydrogen Safety Best Practices (www.h2bestpractices.org) captures this vast knowledge base and makes it publicly available to those working with hydrogen and related systems including those just starting to work with hydrogen. This online manual is organized under a number of hierarchical technical content categories. References including publications and other online links that deal with the safety aspects of hydrogen are compiled for easy access. This paper discusses the development of Hydrogen Safety Best Practices as a safety knowledge tool the nature of its technical content and the steps taken to enhance its value and usefulness. Specific safety event examples are provided to illustrate the link between technical content in the online best practices manual and a companion safety knowledge tool Hydrogen Incident Reporting and Lessons Learned (www.h2incidents.org) which encourages the sharing of lessons learned and other safety event information.

In close cooperation with their Canadian counterparts United States public safety authorities are taking the first steps towards creating a proper infrastructure to ensure the safe use of the new hydrogen fuel cells now being introduced commercially. Currently public safety officials are being asked to permit hydrogen fuel cells for stationary power and as emergency power backups for the telecommunications towers that exist everywhere. Consistent application of the safety codes is difficult – in part because it is new – yet it is far more complex to train emergency responders to deal safely with the inevitable hydrogen incidents. The US and Canadian building and fire codes and standards are similar but not identical. The US and Canadian rules are unlikely to be useful to other nations without modification to suit different regulatory systems. However emergency responder safety training is potentially more universal. The risks strategies and tactics are unlikely to differ much by region. The Hydrogen Executive Leadership Panel (HELP) made emergency responder safety training its first priority because the transition to hydrogen depends on keeping incidents small and inoffensive and the public and responders safe from harm. One might think that advising 1.2 million firefighters and 800000 law enforcement officers about hydrogen risks is no more complicated than adding guidance to a website. One would be wrong. The term “training” has specific legal implications which may vary by state. For hazardous materials federal requirements apply. Insurance companies place training requirements on the policies they sell to fire departments including the thousands of small all-volunteer departments which may operate as private corporations. Union contracts may define training and promotions may be based on satisfactorily completed certain levels of training. Emergency responders could no sooner learn how to extinguish a<br/>hydrogen fire by reading a webpage than a person could learn to ride a bicycle by reading a book. Procedures must be learned by listening reading and then doing. Regular practice is necessary. As new hydrogen applications are commercialized additional responder training may be necessary. This highlights another obstacle emergency responders’ ability to travel distances and take the time to undergo training. Historically fire academies established adjunct instructor programs and satellite academies to bring the training to firefighters. The large well-equipped academies are typically used for specialized training. States rarely have enough instructors and instructors often must take the time to create a course outline research each point and produce a program that is informative useful and holds the attention of responders. The challenge of training emergency responders seems next to impossible but public safety authorities are asked to tackle the impossible every day and a model exists to move forward in the U.S. Over the past few years the National Association of State Fire Marshals and U.S. Department of Transportation enlisted the help of emergency responders and industry to create a standardized approach to train emergency responders to deal with pipeline incidents. A curriculum and training materials were created and more than 26000 sets have been distributed for free to public safety agencies nationwide. More than 8000 instructors have been trained to use these materials that are now part of the regular training in 23 states. Using this model HELP intends to ensure that all emergency responders are trained to address hydrogen risks. The model and the rigorous scenario analysis and review used to developing the operational and technical training is addressed in this paper.

Experience makes a superior teacher. Sharing the details surrounding safety events is one of the best ways to help prevent their recurrence elsewhere. This approach requires an open non-punitive environment to achieve broad benefits. The Hydrogen Incident Reporting Tool (www.h2incidents.org) is intended to facilitate the sharing of lessons learned and other relevant information gained from actual experiences using and working with hydrogen and hydrogen systems. Its intended audience includes those involved in virtually any aspect of hydrogen technology systems and use with an emphasis towards energy and transportation applications. The database contains records of safety events both publicly available and/or voluntarily submitted. Typical records contain a general description of the occurrence contributing factors equipment involved and some detailing of consequences and changes that have been subsequently implemented to prevent recurrence of similar events in the future. The voluntary and confidential nature and other characteristics surrounding the database mean that any analysis of apparent trends in its contents cannot be considered statistically valid for a universal population. A large portion of reported incidents have occurred in a laboratory setting due to the typical background of the reporting projects for example. Yet some interesting trends are becoming apparent even at this early stage of the database’s existence and general lessons can already be taken away from these experiences. This paper discusses the database and a few trends that have already become apparent for the reported incidents. Anticipated future uses of this information are also described. This paper is intended to encourage wider participation and usage of the incidents reporting database and to promote the safety benefits offered by its contents.

In 2020 the Department for Business Enterprise and Industrial Strategy (BEIS) commissioned Energy & Utility Skills to develop and deliver a Hydrogen Competency Framework as part of the Hy4Heat programme. The successful completion of this work is detailed in a new report published today.

The work done by Energy & Utility Skills was underpinned by three key pillars:

Collaboration

• Driving growth in engagement levels across the industry

Scalability

• Designing the framework for both initial trials and any future rollout

Safety

• The framework ensures engineers will have all the skills knowledge and understanding they need

The Hydrogen Competency Framework establishes a series of sequential components designed to ensure any future work done to install and maintain new hydrogen appliances will be completed safely to the highest standards and will only be carried out by hydrogen competent Gas Safe Registered engineers.

The resulting outputs of the design development stages are:

• A Comparative Analysis of Hydrogen and existing hydrocarbon gases
• A Skills Matrix that translates the analysis into skills knowledge and understanding
• An Interim Hydrogen Technical Standard that defines acceptable parameters and requirements for hydrogen installation work
• A Hydrogen Training Specification that will enable training course consistency and facilitate industry recognition
• An independent Hydrogen Assessment Module that will facilitate the addition of a hydrogen competence category on the Gas Safe Register

The Hydrogen Competency Framework is a significant success for the UK Gas Sector. This scalable framework will evolve and expand as the roll out of hydrogen into larger commercial applications occurs ahead of Hydrogen Apprenticeships becoming a reality. In the meantime it delivers the means to ensure the competence of engineers who will pioneer the transition to a hydrogen-fuelled gas industry.

The objective of this pre-normative research (PNR) document entitled EU harmonised terminology for hydrogen generated by electrolysis is to present an open and comprehensive compendium of harmonised terminology for electrolysis applications. This report is prepared under the FWC between JRC and FCH2JU as the result of a collaborative effort between European partners from industry research and development (R&D) organisations and academia participating to FCH2JU funded R&D projects6 in electrolysis applications.7 The commonly accepted definitions of terms may be used in RD&D project documents test and measurement methods test procedures and test protocols scientific publications and technical documentation. This compendium is primarily intended for use by those involved in conducting RD&D as well as in drafting and evaluating R&I programme. The terms and definitions presented cover many aspects of electrolysis including materials research modelling design & engineering analysis characterisation measurements laboratory testing prototype development field tests and demonstration as well as quality assurance (QA). Also it contains information useful for others e. g. auditors manufacturer designers system integrators testing centres service providers and educators. In future it may be expanded to account for possible power-to-hydrogen (P2H2) developments in energy storage (ES) particularly electrical energy storage (EES) hydrogen-to-power (H2P) hydrogen-to-industry (H2I) and hydrogen-to-substance (H2X) applications.

This paper explores the skills landscape of the emerging green hydrogen industry in Australia drawing on data collected from a study that gathered insights on training gaps from a range of hydrogen industry participants. A total of 41 industry participants completed a survey and 14 of those survey respondents participated in industry consultations. The findings revealed widespread perceptions of training and skilling as being very important to the industry but under-provisioned across the sector. Data were analysed to consider the problem of skilling the green hydrogen industry and the barriers and enablers as perceived by industry stakeholders. In this paper we argue that urgent cross-sector attention needs to be paid to hydrogen industry training and skill development systems in Australia if the promise of green hydrogen as a clean energy source is to be realised.
