Safety requirements related to the end-user equipment

This LAP is concerned with the safety requirements (and design and operational aspects) for commercial and domestic end-user equipment operating with hydrogen gas blends resulting from hydrogen injected and transmitted in the gas grid at the TSO level

Glossary:

The requirements needed to guarantee the safety of the end user application.

select country:

Is it a barrier?

Yes

Type of Barrier

Structural barriers, Economic barriers

Assessment Severity

Questions:

Question 1 Is there any legislation with regard to safety requirements related to end-user equipment (e.g.: limits in terms of H2 for use in gas appliances)? If yes, please answer the following question.

Yes

Question 2 Changes to gas supply composition may have implications for the design of gas appliances (safety) and the relevant legislation. What are the implications you expect with regard to the possible concentrations of hydrogen in the H2NG blend?

the GAD specifically permits Notified Bodies to certify nearly all gaseous fuel appliances against the fundamental requirements of the GAD and manufacturers can (and have already) brought hydrogen appliances to market

Question 3 For which end user applications do you foresee the main consequences and at which level? Could you please provide references to underpin your opinion?

Domestic and commercial gas appliances. l

Question 4 Changes to gas supply composition may have implications for CNG compression, storage, and use in CNG vehicles. What are the additional safety precautions needed? Could you please provide references to underpin your opinion

Assessment had to be carried out for each type of installation.
