In January 2022 the chair of IGC changed from Air Liquide (François de Bussy) to SIAD (Giorgio Bissolotti) . In 2022 there will be some changes in the IGC as three people have announced their retirement.
In 2021 WG-14 was re-titled to Hydrogen production (previously HyCO) and WG-18, Nitrous Oxide was created.
Themes emerging from the WGs (short summary of the main critical items of the WGs)
Items that could have a business direct impact are connected to the retesting of cylinders or battery vehicles (see WG-1 and WG-2). For cylinders there was a positive news relating to the agreement on the mutual recognition, which enter in force in the 2023, between Europe and the United States (DOT).
The items that need attention for the future relate to hydrogen regulation (see WG-11 and WG- 14) and, in general, the presence of EIGA members in the associations that prepare the standards/norms. The specification relating to hydrogen used in fuel cells which, thanks to the work of the WG-11, has been positively influenced according to the ideas in our sector.
The start of the work of some WGs (WG-14 and 18) and the quantity of technical documents produced by many working groups should also be highlighted.
DOT cylinders: changes in progress in the code of Federal Regulations 49 CFR. DOT cylinders will enter into ADR 2023 which is a very good news. The next step should be to recognise worldwide EU (ADR) and DOT cylinders. No news since last report, but still under observation of WG-1.
Cylinder periodic inspection of tubes in battery vehicles
More work is required to achieve the 15 years periodic inspection of tubes in battery vehicles. A specific WG should be created with stakeholders.
UN Disilane Air Transport
Creation of UN number for disilane: EIGA has withdrawn its original paper upon the request of CGA who were not in line with the EIGA position. CGA will prepare a new paper for a later UN meeting in coordination with EIGA. On hold for now.
Fuel Cell/Fully Electric Trucks ADR Task Force for Transportation of Dangerous Goods.
EIGA representatives participate in the meetings with competent authorities, manufacturers and other interested parties. It is not believed that Battery Electrical Vehicles (BEV) or Fuel Cell Electrical Vehicles (FCEV) with enter ADR before 2025.
Consequences of BLEVE meetings: three measures will enter ADR in order to mitigate BLEVE incidents. These are fire resistant mudguards, engine fire suppression system and safety valves for tanks. Safety valves on tanks are less relevant to the industrial gases industry since all of its equipment has safety valves in line with regulations anyway. Currently it is still unclear if the two relevant measures will also apply to compressed gases.
In-house Cylinder Retesting
There was discussion in the Tanks WG on the scope of work to be allowed for in-house inspection services (IS). There is a proposal to restrict their capabilities only to pressure receptacles that they own themselves. This would make retesting more expensive without added value. EIGA argued accordingly and submitted an INF document which was discussed.
WG-2: Gas Cylinders and Pressure Vessels
Cylinder wall thickness to reject cylinders
EIGA and ECMA agree to allow isolated pits and to allow a percentage below minimum wall thickness. However, different positions exist on the wall thickness to reject cylinders.
Tubes trailers 15 years retest regime (on going). Inert gases, H2 and He.
There was not a common position between WG2 and ECMA to increase the testing interval up to 15 years. It was decided to create an EIGA+ECMA informal working group to discuss the provisions under which an extension of the retest up to 15 years could be eventually accepted. Informal Working Group will start end of January 2022.
WG-3: Atmospheric Gases Process & Equipment
DOC 43-Cryogenic carbon absorbers.
Cryogenic carbon absorbers, DOC 43. It was proposed to archive the document as there was no real interest to update document.
Availability of experts in specialty gases
Availability of experts in specialty gases seems to be a problem due to its scarcity.
Harmonisation of EIGA documents with CGA documents
The work method is being optimised.
There is a large number of documents under revision
Materials in contact whit food gases.
A new document was drafted following the last conference call of the AHG 8.4 Food Contact Material a new document was drafted => Title “Guidelines for assessment of materials in contact with food gases”
Hydrogen quality specification
There are a number of new standards/norms on hydrogen:
- ISO 14687-2 « Hydrogen fuel -- Product specification -- Part 2: Proton exchange membrane (PEM) fuel cell applications for road vehicles »
- ISO 19880-8 : « Gaseous hydrogen — Fuelling stations — Part 8: Fuel quality control »
- EN 17124 « Hydrogen fuel - Product specification and quality assurance - Proton exchange membrane (PEM) fuel cell applications for road vehicles”.
WG-11 has been mandated by CEN TC268 WG-5 to propose a draft document for a European standard for H2 quality.
Refueling Protocols are defining the way to fill cars or other vehicles from a refueling station. They are one of the key factors for safe supply of H2 to mobility applications. WG-11 has initiated work to build a common position concerning the expectations of the H2 suppliers about the next generation of refueling protocols to be implemented on cars after 2025.
Interface HRS, Tube Trailer:
Establish an industry position about standardisation of the interface between tube trailer and H2 Refueling Station – WG-11 decided to put on hold due to lack of alignment internally for each member.
Preparing standardisation activity related to new usages of Liquid H2 for H2 energy infrastructure. EIGA needed to be able to share relevant docs to prepare the work on those standards. WG-11 may develop a position.
Implementation of DMF restriction uses
The restriction of DMF uses has been issued. This information will be included in the EIGA documents.
WG-14: Hydrogen production (previously HyCO)
H2 safety and handling and H2 production methods
Currently working on two new documents: the first is an overview of H2 safety and handling, the second is an overview of H2 production methods. We are mindful that there are a lot of newcomers to the H2 business, so we are starting with basics. We are also continuing with literature reviews with a plan to focus next on plugging any gaps. Plan to have meeting with WG-11 to get more familiar with their activities and to ensure we are aligned (WG-11 focus is on H2 energy and users).
Analysis of the incidents
All companies listed known incidents in a table. The majority of the incidents have been analysed. For all reviewed accidents, lessons learned and a number of requirements have been listed, in order to be matched with the existing documentation in a gap analysis.
