About Course

Hydrogen Expert Programme is a specialist, professionally designed training course tailored for participants with foundational knowledge and recognised practical experience in hydrogen technologies and applications.

The programme aims to provide a comprehensive understanding of hydrogen’s diverse properties, risk assessment methodologies, safety checklists, and internationally recognised best practices related to hydrogen production, storage, handling, and associated processes. It also covers hazard identification, emergency response planning, and applicable occupational health and safety standards.

This programme is suitable for safety specialists, engineers, technicians, environmental experts, and professionals working — or intending to work — in hydrogen production, transport, industrial applications, and sustainability sectors.

Upon successful completion of the programme, participants will receive a Hydrogen Safety Professional Certificate, demonstrating their competence in managing occupational safety requirements in line with global industry standards.

Course Content

CERTFIED HYDROGEN SAFETY SPECILIST
This Emergency Response Guide on hydrogen and fuel cell applications for First Responders was first produced within the Response project. This guide is intended to be used by emergency response personnel, both by front-liners and commanders, from the moment they have received an emergency call until the FINAL INSPECTION. It is expected that this guide will support the decision-making personnel, who already have knowledge of emergency response operations and procedures. This revised version includes events related to liquefied hydrogen (LH2). New vectors of mobility and transport such as buses, trucks and trains have been added. Moreover, a new set of operational tactical sheets have been inserted and the previous version has been enriched with multiple contributions.

MODULE 2 (Properties of hydrogen relevant to safety)
This lecture outlines the properties of hydrogen relevant to safety. The advantages of hydrogen over traditional hydrocarbon-based fuels are very clear:  it does not produce any CO2 emissions during combustion;  hydrogen is capable to produce more energy per unit mass;  it can be generated from a range of renewable sources such as wind, sun, tidal and hydro-power. From a safety point of view, hydrogen is not more or less dangerous than other fuels, but it is different. This difference is in its specific physical properties and combustion characteristics. Not only first responders but the members of general public should be aware of these properties as they are directly linked to hazardous behaviour of hydrogen. For example, hydrogen leaks are difficult to detect by human senses because it is colourless, odourless and tasteless. Hydrogen has an invisible flame when it burns in a clean atmosphere. It is prone to leakage, and hydrogen fires can escalate to explosions. Nevertheless, the main safety asset of hydrogen is its highest among other gases buoyancy, which allows it to flow out of an incident/accident scene and to mix with air to a safe concentration levels. This lecture relates hydrogen structural, physical, chemical, ignition, combustion and other characteristics to a range of safety considerations. It also compares the main parameters of hydrogen against those for traditional fuels, which are currently in use.

MODULE 3 (Hydrogen storage)
This lecture introduces different hydrogen storage options – compressed, liquefied and in solid materials, as well as hazards and safety issues associated with them. Specifically catastrophic rupture of the vessels is introduces along with online tools which may be used.

MODULE 4 (Compatibility of hydrogen with different materials)
The present lecture gives an overview of hydrogen interaction with different types of materials and hydrogen permeation, which are extremely relevant to hydrogen storage technologies. Although hydrogen is a non-corrosive gas, the reaction of hydrogen with some metals at high temperature may form corrosive hydrides, which then generates gas bubbles within the metal lattice, known as blistering. At low temperatures, some metal could become more brittle due to the change from ductile to brittle behaviour mode, which is called cold embrittlement. The interaction of hydrogen with polymer could also lead to swelling, blistering and deterioration of the polymer, increasing the permeation rate of hydrogen through the polymer matrix. The permeation rate of hydrogen through metallic containers (i. e. Type I and Type II) or containers with metallic liners (i. e. Type III) is negligible. However, the hydrogen permeation rate through Type IV containers must be correctly controlled to a very low value, to avoid the concentration of hydrogen reaching the LFL of hydrogen in air (4.0 vol. %).

MODULE 5 (Safety of liquefied hydrogen)
For various applications of hydrogen where volume is an essential issue, liquified hydrogen (LH2) is a necessary for the sake of volume reduction. However, there are also other situations where the liquid state represents a reasonable and economic solution for storage and distribution of large amounts of hydrogen depending on the end-user’s requirements. Furthermore, LH2 has the advantage of extreme cleanliness making it appropriate in many industrial applications. Major drawback is the enormous energy input required to liquefy the hydrogen gas, which has a significant impact on the economy of handling LH2. The hazards associated with the presence and operation of LH2 containing systems are subject of safety and risk assessments. Essential part of such accident sequence analyses is the simulation of the physical phenomena which occur in connection with the inadvertent release of LH2 into the environment by computation models. The behaviour of cryogenic pool propagation and vaporization on either a liquid or a solid ground as well as potential pool burning is principally well understood. Furthermore, state-of-the-art computer models have been developed and validated against respective experimental data. There are, however, still open questions which require further efforts to extent the still poor experimental data basis. This lecture is based on the Deliverable 6.1 – Handbook of hydrogen safety: Chapter on LH2 safety – of Pre-normative REsearch for Safe use of Liquid Hydrogen (PRESLHY) project. The experimental and theoretical investigation of the characteristics of liquid hydrogen, its favourable and unfavourable properties, as well as the lessons learnt from accidents have led to a set of codes, standards, regulations, and guidelines, which resulted in a high level of safety achieved today. This applies to both LH2 production and the methods of mobile or stationary LH2 storage and transportation/distribution, and its application in both science and industries.

MODULE 6 (Harm criteria for people and property)
This lecture provides responders with valuable information on the impact of hydrogen leaks, fires and explosions on the health and environment of humans. It also considers the damage to structures and equipment caused by hydrogen fires and overpressure events.

MODULE 7 (Unignited hydrogen releases outdoors and their mitigation)
Unwanted hydrogen releases are followed by the mixing of escaped gas with air, thus establishing the initial conditions for fire and explosion hazards. The unignited releases involve the escape of compressed gaseous hydrogen stored at high pressures at FCH systems and infrastructure.

MODULE 8 (Ignition sources and prevention of ignition)
Hydrogen is easily ignited due to having the lowest minimum ignition energy (MIE) amongst known fuels. It is often difficult to establish the exact source of hydrogen ignition and to determine its specific mechanism. This lecture gives an overview of hydrogen ignition incidents and mechanisms.

MODULE 9 (Hazard distances from hydrogen flames and fire fighting)
This lecture is focused on ignited hydrogen releases. A useful terminology has been introduced at the start. Then a classification of different types of hydrogen fires is provided

MODULE 10 (Dealing with hydrogen explosions)
This lecture considers the main features of ‘chemical’ explosions, i.e. deflagrations and detonations, and ‘physical explosions’, i.e. tank ruptures.
